Litter was collected from eight sites at distances as far as 33 km from an Al reduction plant in western Tennessee. As a result of an accumulation of fine litter (<4.75 mm) the weight of the litter per unit area was abnormally high at the two sites within 2 km of the plant. Compared to litter collected far from the plant, it had a lower fiber content, was more sapric, and was less acid. Fluoride emissions from the plant were suggested as the probable cause of litter changes. Concentrations of water-extractable and acid-extractable F− in the litter, the 0- to 5-cm soil layer, and the 5- to 15-cm soil layer were strongly correlated with distance from the plant. Total acid-extractable F− in the litter and upper 15 cm of soil was about 41 times as much at the closest site (700 mg/kg) as at the most distant sites (12 and 16 mg/kg). In a bioassay of litter from our study sites, woodlice (Porcellio scaber Latr.) had an abnormally high mortality in litter that contained 440 mg/kg or more of acid-extractable F−. However, when F− was added as NaF to litter, a significant increase in mortality was observed only in treatments exceeding 800 mg/kg. The decrease in the rate of decomposition of the litter might eventually induce a deficiency of soil macronutrients, but none was detected.

Edwin B. Forsythe NWR (BNW) during three field seasons (1983-1896). Use of the BNWR impoundments was strongly associated with open vs. closed hunting seasons and with presence or absence of ice cover. Black ducks primarily used the impoundments for daytime roost sites and fed in saltmarsh areas at night during the hunting season. Following the hunting season use generally dispersed to saltmarsh and inland freshwater habitats. Freeze-up of the impoundments resulted in dispersal of black ducks to saltmarsh, inland freshwater, or areas to the south of New Jersey. We conclude that the BNWR impoundments only partially meet the habitat requirements of wintering black ducks. Access to saltmarsh habitats for feeding, and to inland freshwater habitats during periods of hard freeze, may be critical. The utility of the BNWR impoundments to black ducks, needs to be considered in conjunction with the availability of these other important habitats.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Waterfowl and Wetlands Symposium: Proceedings of a Symposium on Waterfowl and Wetlands Management in the Coastal Zone of the Atlantic Flyway","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Delaware Coastal Management Program, Delaware Department of Natural Resources and Coastal Control","publisherLocation":"Dover, Delaware","usgsCitation":"Conroy, M., Costanzo, G., and Stotts, D.B., 1987, Winter movements of American black ducks in relation to natural and impounded wetlands in New Jersey, chap. of Waterfowl and Wetlands Symposium: Proceedings of a Symposium on Waterfowl and Wetlands Management in the Coastal Zone of the Atlantic Flyway, p. 31-45.","productDescription":"v, 522","startPage":"31","endPage":"45","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201386,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dee4b07f02db5e30fd","contributors":{"editors":[{"text":"Whitman, William R.","contributorId":111631,"corporation":false,"usgs":true,"family":"Whitman","given":"William","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":506140,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Meredith, William H.","contributorId":113637,"corporation":false,"usgs":true,"family":"Meredith","given":"William H.","affiliations":[],"preferred":false,"id":506141,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Conroy, M.J.","contributorId":84690,"corporation":false,"usgs":true,"family":"Conroy","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":328027,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Costanzo, G.R.","contributorId":17960,"corporation":false,"usgs":true,"family":"Costanzo","given":"G.R.","email":"","affiliations":[],"preferred":false,"id":328026,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stotts, Daniel B.","contributorId":90003,"corporation":false,"usgs":true,"family":"Stotts","given":"Daniel","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":328028,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5210002,"text":"5210002 - 1987 - Acid rain effects on waterfowl: Use of black duck broods to assess food resources of experimentally acidified wetlands","interactions":[],"lastModifiedDate":"2012-02-02T00:15:17","indexId":"5210002","displayToPublicDate":"2009-06-09T09:23:16","publicationYear":"1987","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"seriesNumber":"6","title":"Acid rain effects on waterfowl: Use of black duck broods to assess food resources of experimentally acidified wetlands","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"The Value of Birds.

The ratio was determined as the slope of a Model II regression of POC' against (Chla), where POC' is total particulate organic carbon minus sediment-associated non-phytoplankton carbon. Samples from 30 fixed sites in the channel and lateral shoals of San Francisco Bay were collected once or twice a month from April to November 1980, and at irregular intervals in South Bay during 1984 and 1985. For all data the calculated mean value of phytoplankton C:Chla was 51 (95% confidence interval = 47–54). No significant differences were found in the C:Chla ratio between shallow and deep sites (where light availability differs) or between northern and southern San Francisco Bay (where phytoplankton community composition differs). Using the mean C:Chla ratio of 51, we calculated that phytoplankton biomass constitutes about one third of seston carbon under most circumstances, but this fraction ranges from about 95% during phytoplankton blooms to less than 20% during spring periods of low phytoplankton biomass and high suspended sediment concentration.

This calculation depends on several quantities, such as water-surface fall, that are subject to large measurement errors. Other critical quantities, such as Manning's n, are not even amenable to direct measurement but can only be estimated. Finally, scour and fill may cause gross discrepancies between the observed condition of the channel and the hydraulic conditions during the flood peak.
The effects of these potential errors on the accuracy of the computed discharge have been estimated by statistical error analysis using a Taylor-series approximation of the discharge formula and the well-known formula for the variance of a sum of correlated random variates. The resultant error variance of the computed discharge is a weighted sum of covariances of the various observational errors. The weights depend on the hydraulic and geometric configuration of the channel.
The mathematical analysis confirms the rule of thumb that relative errors in computed discharge increase rapidly when velocity heads exceed the water-surface fall, when the flow field is expanding and when lateral velocity variation (alpha) is large. It also confirms the extreme importance of accurately assessing the presence of scour or fill.

Peak stages can sometimes be determined for outstanding floods that occurred many years ago before systematic gaging of streams began. In the United States, this information is usually not available for more than 100-200 years, but in countries with long cultural histories, such as China, historical flood data are available at some sites as far back as 2,000 years or more. It is important in flood studies to be able to assign a maximum discharge rate and an associated error range to the historical flood.
This paper describes the significant characteristics and uncertainties of four commonly used methods for estimating the peak discharge of a flood. These methods are: (1) rating curve (stage-discharge relation) extension; (2) slope conveyance; (3) slope area; and (4) step backwater. Logarithmic extensions of rating curves are based on theoretical plotting techniques that results in straight line extensions provided that channel shape and roughness do not change significantly. The slope-conveyance and slope-area methods are based on the Manning equation, which requires specific data on channel size, shape and roughness, as well as the water-surface slope for one or more cross-sections in a relatively straight reach of channel. The slope-conveyance method is used primarily for shaping and extending rating curves, whereas the slope-area method is used for specific floods. The step-backwater method, also based on the Manning equation, requires more cross-section data than the slope-area ethod, but has a water-surface profile convergence characteristic that negates the need for known or estimated water-surface slope.
Uncertainties in calculating peak discharge for historical floods may be quite large. Various investigations have shown that errors in calculating peak discharges by the slope-area method under ideal conditions for recent floods (i.e., when flood elevations, slope and channel characteristics are reasonably certain), may be on the order of 10-25%. Under less than ideal conditions, where streams are hydraulically steep and rough, errors may be much larger. The additional uncertainties for historical floods created by the passage of time may result in even larger errors of peak discharge.

In the United States, the possibility that flood peaks were overestimated and the closeness of these peaks to the probable maximum floods suggest that this limiting curve of maximum floods will not significantly change position with more data. Data for future floods that plot above this curve need to be examined carefully. The most likely interpretations for new data points above the curve would be the confusion of a mud or debris flow with a water-dominated flood, or the damming of channels by debris or a landslide and subsequent bursting. In the United States, excluding Hawaii, the largest measured historic floods in basins less than about 1000 km2, all occurred in arid and semi-arid areas. In China, the majority of the largest measured historic floods occurred in the east and southeast in basins on the windward side of mountainous areas, and in locations affected by typhoons. One extraordinary flood that exceeds any other recorded flood in the world for the size of the drainage basin in which it occurred is the New Caledonia flood of December 24, 1981 on the Ouaieme River. Worldwide, the largest measured historic floods occurred primarily between 40°N and 40°S latitude on streams and rivers near coastal areas.

Results indicate that despite the discontinuous nature of the local aquifers, many wells have good hydraulic connection with Devils Hole. Hydraulic connection between the wells and Devils Hole exhibits a complex spatial variability typical of carbonate terrane. Zones or directions of minimal hydraulic connection may result from fault-controlled structural discontinuities. Zones or directions of enhanced hydraulic connection point to the presence of large-scale groundwater flow through fractures or conduits. The orientation of waterbearing fractures or conduits inferred from this study is qualitatively consistent with the major orientation of local and regional structural features.

This system is analyzed in cross section with a variable-density groundwater flow and solute transport model on a regional scale. The simulation is difficult, because the coastal aquifer system has a saltwater transition zone that is broadly dispersed near the discharge area, but is very sharply defined inland. Steady-state simulation analysis of the transition zone in the layered basalt aquifer of southern Oahu indicates that a small transverse dispersivity is characteristic of horizontal regional flow. Further, in this system flow is generally parallel to isochlors and steady-state behavior is insensitive to the longitudinal dispersivity. Parameter analysis identifies that only six parameters control the complex hydraulics of the system: horizontal and vertical hydraulic conductivity of the basalt aquifer; hydraulic conductivity of the confining \"caprock\" layer; leakance below the caprock; specific yield; and aquifer matrix compressibility. The best-fitting models indicate the horizontal hydraulic conductivity is significantly greater than the vertical hydraulic conductivity. These models give values for specific yield and aquifer compressibility which imply a considerable degree of compressive storage in the water table aquifer.

This analysis identified twelve floods that were the largest ever measured. These floods all occurred in semiarid to arid areas.
For eleven of the twelve largest rainfall-runoff floods measured in small basins by the slope-area method, values of hydraulic depth; hydraulic radius; width-depth ratio; n value; mean velocity; velocity-head coefficient; Froude number; water-surface, energy, and channel slopes; shear stress; and unit stream power are tabulated. Estimated composite n values weighted by subsection conveyance range from 0.028 to 0.048 with a mean of 0.038. Mean velocities ranged from 3.47 to 9.97 m s−1. Froude numbers ranged from 0.81 to 2.49, with 9 of 12 floods having values greater than 1.00.
Water-surface, energy, and channel slopes vary considerably for each flood. Energy slope always was less than water-surface slope by values of 1–104%. Channel slope was greater than energy slope in eight floods. Shear stresses ranged between 61 and 855 N m−2, and unit stream power from 212 to 8131 w m−1.
Floods in these small basins produced shear stresses and unit stream powers several hundred times greater than floods in large rivers. Floods on other small streams, with smaller unit discharges, produced greater shear stresses and stream powers. This indicates that the force of a flood is controlled by the depth-slope product, not absolute discharge.
In the twelve watersheds studied, basin relief ranged from 165 to 1280 m, elongation ratios ranged from 0.55 to 0.80, the number of first-order streams (basin magnitude) ranged from 10 to 4297, drainage density ranged from 4.1 to 10.9 km km−2, basin slope ranged from 0.0043 to 0.2486, relief ratio ranged from 0.0097 to 0.34, ruggedness number ranged from 0.69 to 7.17, and first-order channel frequency ranged from 5.1 to 38.6 km−2. Elongation ratios were larger, and drainage density and first-order channel frequency lower, than other small flash-flood prone basins in the United States. These twelve basins have neither the most favorable morphometric characteristics which contribute to flash-flood peaks, nor did the storms causing these flash floods have the greatest short-duration intensities. Maximum flood peaks originate from an optimal combination of basin morphology and physiography, and storm intensity.
