For moderate floods, the influence of basin geology is apparent in modifying severity of flooding, but for the most extreme events, flood discharges relate mainly to rainfall characteristics such as intensity, duration, storm size, and location. Landslide susceptibility relates more directly to geologic controls that determine what intensity and duration of rainfall will trigger slope instability.</p><p>Large floods and landslides are not necessarily effective in producing prominent geomorphic features. Large historic floods in the Piedmont have been minimally effective in producing prominent and persistent geomorphic features. In contrast, smaller floods in the Valley and Ridge produced erosional and depositional features that probably will require thousands of years to efface. Scars and deposits of debris slide-avalanches triggered on sandstone ridges recover slowly and persist much longer than scars and deposits of smaller landslides triggered on finer-grained regolith, even though the smaller landslides may have eroded greater aggregate volume.</p><p>The surficial stratigraphic record can be used to extend the spatial and temporal limits of our knowledge of catastrophic events. Many prominent alluvial and colluvial landforms in the central Appalachians are composed of sediments that were deposited by processes similar to those observed in historic catastrophic events.

Buoyancy stratification, downgradient advection, and hydrodynamic dispersion are the principal natural processes that reduce the amount of injected water that can be recovered. Buoyancy stratification is shown to depend on injection-zone permeability and the density contrast between injected and saline native water. Downgradient advection occurs as a result of natural or induced hydraulic gradients in the aquifer. Hydrodynamic dispersion reduces recovery efficiency by mixing some of the injected water with native saline aquifer water. In computer simulations, the relation of recovery efficiency to volume injected and its improvement during successive injection-recovery cycles was shown to depend on changes in the degree of hydrodynamic dispersion that occurs.

The attendant acidic conditions solubilise a host of trace metals. Within this flow regime the potential exists to contaminate surface drinking water supplies with a variety of trace materials. Accordingly, in evaluating the applications for mines located in the headwaters of water sheds, the pre-mining prediction of the occurrence of acid mine drainage is of paramount importance. There is general agreement among investigators that coal organic sulphur is a nonparticipant in acid mine drainage generation; however, there is no scientific documentation to support this consensus. Using simulated weathering, kinetic, mass balance, petrographic analysis and a peroxide oxidation procedure, coal organic sulphur is shown to be a nonparticipant in acid mine drainage generation. Calculations for assessing the acid-generating potential of a sedimentary rock should not include organic sulphur content.</p>","language":"English","publisherLocation":"Kluwer Academic Publishers","doi":"10.1007/BF01758669","issn":"02694042","usgsCitation":"Casagrande, D., Finkelman, R.B., and Caruccio, F., 1989, The non-participation of organic sulphur in acid mine drainage generation: Environmental Geochemistry and Health, v. 11, no. 3-4, p. 187-192, https://doi.org/10.1007/BF01758669.","productDescription":"6 p.","startPage":"187","endPage":"192","numberOfPages":"6","costCenters":[],"links":[{"id":224158,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bae22e4b08c986b323f1f","contributors":{"authors":[{"text":"Casagrande, D.J.","contributorId":13378,"corporation":false,"usgs":true,"family":"Casagrande","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":371087,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Finkelman, R.

Three types of landslides are analyzed: (1) old, coherent slumps and block slides, which have eroded and revegetated features and no active analogs in the area; (2) old earth flows, which are also eroded and revegetated; and (3) young rotational slumps, which are present only along near-river bluffs, and which are the only young, active landslides in the area. Discriminant analysis shows that only one characteristic differs significantly between bluffs with and without young rotational slumps: failed bluffs tend to have sand and clay at their base, which may render them more susceptible to fluvial erosion. Bluffs having old coherent slides are significantly higher, steeper, and closer to the hypocenters of the 1811-12 earthquakes than bluffs without these slides. Bluffs having old earth flows are likewise higher and closer to the earthquake hypocenters. Multiple regression analysis indicates that the distribution of young rotational slumps is affected most strongly by slope steepness: about one-third of the variation in the distribution is explained by variations in slope steepness. The distribution of old coherent slides and earth flows is affected most strongly by slope height, but the proximity to the hypocenters of the 1811-12 earthquakes also significantly affects the distribution. The results of the statistical analyses indicate that the only recently active landsliding in the area is along actively eroding river banks, where rotational slumps formed as bluffs are undercut by the river. The analyses further indicate that the old coherent slides and earth flows in the area are spatially related to the 1811-12 earthquake hypocenters and were thus probably triggered by those earthquakes. These results are consistent with findings of other recent investigations of landslides in the area that presented field, historical, and analytical evidence to demonstrate that old landslides in the area formed during the 1811-12 New Madrid earthquakes. Results of the multiple linear regression can also be used to approximate the relative susceptibility of the bluffs in the study area to seismically induced landsliding.&nbsp;</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0013-7952(89)90044-6","issn":"00137952","usgsCitation":"Jibson, R., and Keefer, D.K., 1989, Statistical analysis of factors affecting landslide distribution in the new Madrid seismic zone, Tennessee and Kentucky: Engineering Geology, v. 27, no. 1-4, p. 509-542, https://doi.org/10.1016/0013-7952(89)90044-6.","productDescription":"34 p.","startPage":"509","endPage":"542","numberOfPages":"34","costCenters":[],"links":[{"id":223990,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Kentucky, Tennessee","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -90.52812986039102,\n              34.97478273364989\n            ],\n            [\n              -88.22100095414115,\n              34.97478273364989\n            ],\n            [\n              -88.22100095414115,\n              37.40389220228255\n            ],\n            [\n              -90.52812986039102,\n              37.40389220228255\n            ],\n            [\n              -90.52812986039102,\n              34.97478273364989\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"27","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9711e4b08c986b31b86d","contributors":{"authors":[{"text":"Jibson, R.W.","contributorId":8467,"corporation":false,"usgs":true,"family":"Jibson","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":371065,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keefer, D.

Geologic and geophysical studies from the Arabian continental margin in the southern Red Sea and LANDSAT analysis of the northern Somalia margin in the Gulf of Aden suggest that the early continental rifts were long narrow features that formed by extension on closely spaced normal faults above moderate- to shallow-dipping detachments with break-away zones defining one rift flank and root zones under the opposing rift flank. The rift flanks presently form the opposing continental margins across each ocean basin. The detachment on the Arabian margin dips gently to the west, with a breakaway zone now eroded above the deeply dissected terrain of the Arabian escarpment. The Arabian detachment projects westward to middle crustal levels beneath the sediment of the southern Red Sea coastal plain. Strata in the upper plate dip as steeply as 60° to the west, and the beds are repeated by numerous planar and listric normal faults that dip to the east. Most of the faults truncate downward at the detachment. Thus, the upper plate is highly extended and the rocks in its eastern part have been translated about 20 km westward and 21/2- to 5-km downward relative to the rest of Arabia. A prominent detachment surface, with a north dip, is evident in northernmost Somalia where it breaks away north of the Somalian escarpment in an otherwise undeformed section of cratonic strata of Jurassic to Eocene age. The upper plate of the Somalian detachment consists of a highly faulted collage of the cratonic strata.

The second, third, and fifth tuff sequences are of crystal-rich dacite that forms extensive simple cooling-unit outflow sheets and partial caldera fillings of compound cooling units.

Greater detail may be of value to surveyors trying to follow old land deed descriptions, or to pilots of small planes or small pleasure boats operating in inland waterways. It would be extremely expensive to make adequate declination measurements needed for such a chart. It was hoped that declination details could be derived from the information contained in the existing magnetic anomaly map of the United States. This could be realized only if all of the survey data were corrected to a common epoch, at which time a main-field vector model was known, before the anomaly values were computed. Because this was not done, accurate declination values cannot be determined. In spite of this conclusion, declination values were computed using a common main-field model for the entire United States to see how well they compared with observed values. The provisional geomagnetic reference field for 1978.5 was used as the main-field model. The computed detailed declination values were found to compare less favorably with observed values of declination than declination values computed from the IGRF 1985 model itself. This result indicates that the computed anomaly elements or their combination with main-field values cannot be used as accurate anomaly values, but they may be used as an indication of where anomalies probably occur.</p></div><div id=\"datarepo-wrap\"><br></div><div id=\"article-overiew-references-wrap\"><br></div>","language":"English","publisher":"J-STAGE","doi":"10.5636/jgg.41.549","usgsCitation":"Alldredge, L., 1989, An attempt to obtain a detailed declination chart from the United States magnetic anomaly map: Journal of Geomagnetism & Geoelectricity, v. 41, no. 6, p. 549-563, https://doi.org/10.5636/jgg.41.549.","productDescription":"15 p.","startPage":"549","endPage":"563","numberOfPages":"15","costCenters":[],"links":[{"id":479884,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5636/jgg.41.549","text":"Publisher Index Page"},{"id":224096,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ea1ee4b0c8380cd48642","contributors":{"authors":[{"text":"Alldredge, L.R.","contributorId":53457,"corporation":false,"usgs":true,"family":"Alldredge","given":"L.R.","email":"","affiliations":[],"preferred":false,"id":371075,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Biostratigraphic ties are available to exploratory wells at three of the sites. Uniform, slow accumulation of hemipelagic sediments was locally terminated by the late Miocene sea-level lowering, which is also reflected in changes in foraminiferan faunas on the continental shelf. Data are very limited for the early Pliocene but suggest a return to slow hemipelagic sedimentation. At the beginning of the late Pliocene, there was a change in sedimentation style marked by a several-fold increase in accumulation rates and cutting of slope valleys. This late Pliocene cutting of slope valleys corresponds to the onset of late Cenozoic growth of the Laurentian Fan and the initiation of turbidite sedimentation on the Sohm Abyssal Plain. Although it corresponds to a time of sea-level lowering, the contrast with the late Miocene lowstand indicates that there must also have been a change in sediment delivery to the coastline, perhaps as a result of increased rainfall or development of valley glaciers. High sedimentation rates continued into the early Pleistocene, but the extent of slope dissection by gullies increased. Gully-cutting episodes alternated with sediment-draping episodes. Throughout the southeastern Canadian continental margin, there was a change in sedimentation style in the middle Pleistocene that resulted from extensive ice sheets crossing the continental shelf and delivering coarse sediment directly to the continental slope. ?? 1989.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine and Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0264-8172(89)90030-5","issn":"02648172","usgsCitation":"Piper, D., and Normark, W.R., 1989, Late Cenozoic sea-level changes and the onset of glaciation: impact on continental slope progradation off eastern Canada: Marine and Petroleum Geology, v. 6, no. 4, p. 336-347, https://doi.org/10.1016/0264-8172(89)90030-5.","startPage":"336","endPage":"347","numberOfPages":"12","costCenters":[],"links":[{"id":224206,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268649,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0264-8172(89)90030-5"}],"volume":"6","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a44c9e4b0c8380cd66da0","contributors":{"authors":[{"text":"Piper, D.J.W.","contributorId":17351,"corporation":false,"usgs":false,"family":"Piper","given":"D.J.W.","email":"","affiliations":[{"id":7219,"text":"Natural Resources Canada","active":true,"usgs":false}],"preferred":false,"id":371090,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Normark, W.

Dune fields occur along Morgan peninsula between the foredune line and Little Lagoon and the Mobile Bay area. These dune fields consist primarily of one or more continuous ridges that parallel the coast and are generally vegetaed to grassy. Washover of the beach and backshore during Hurricane Frederic (1979) and subsequent smaller scale storms resulted in significant erosion of many of Alabama's dune fields. The primary dunes or foredunes are beginning to recover from the effects of these storms; however, numerous breaks in the primary dune line are present. Sand dunes in coastal Alabama provide protection against storm-generated waves and washover. The foredunes are protected by adherence to a Coastal Construction Control Line (CCCL) or construction setback line identified by markers along coastal Baldwin County.","largerWorkTitle":"Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management","conferenceTitle":"Coastal Zone '89: Proceedings of the Sixth Symposium on Coastal and Ocean Management","conferenceDate":"11 July 1989 through 14 July 1989","conferenceLocation":"Charleston, SC, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","usgsCitation":"Bearden, B.L., Hummell, R.L., and Mink, R.M., 1989, Geomorphology of coastal sand dunes, Baldwin County, Alabama, <i>in</i> Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management, v. 2, no. pt2, Charleston, SC, USA, 11 July 1989 through 14 July 1989, p. 1038-1050.","startPage":"1038","endPage":"1050","numberOfPages":"13","costCenters":[],"links":[{"id":223718,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"pt2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a27a9e4b0c8380cd59ab5","contributors":{"authors":[{"text":"Bearden, Bennett L.","contributorId":71318,"corporation":false,"usgs":true,"family":"Bearden","given":"Bennett","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":371028,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hummell, Richard L.","contributorId":68040,"corporation":false,"usgs":true,"family":"Hummell","given":"Richard","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":371027,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mink, Robert M.","contributorId":41972,"corporation":false,"usgs":true,"family":"Mink","given":"Robert","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":371026,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
