Network habitat analysis refers to the evaluation of an entire river basin (or network) by predicting its habitat response to alternative management regimes.  The analysis principally focuses on the biological and hydrological components of the riv er basin, which include both micro- and macrohabitat.  (The terms micro- and macrohabitat are further defined and discussed later in this document.)  Both conceptual and analytic models are frequently used for simplifying and integrating the various components of the basin.  The model predictions can be used in developing management recommendations to preserve, restore, or enhance instream fish habitat.</p>\n<br/>\n<p>A network habitat analysis should begin with a clear and concise statement of the study objectives and a thorough understanding of the institutional setting in which the study results will be applied.  This includes the legal, social, and political considerations inherent in any water management setting.  The institutional environment may dictate the focus and level of detail required of the study to a far greater extent than the technical considerations.  After the study objectives, including species on interest, and institutional setting are collectively defined, the technical aspects should be scoped to determine the spatial and temporal requirements of the analysis.  A macro level approach should be taken first to identify critical biological elements and requirements.  Next, habitat availability is quantified much as in a \"standard\" river segment analysis, with the likely incorporation of some macrohabitat components, such as stream temperature.  Individual river segments may be aggregated to represent the networkwide habitat response of alternative water management schemes.  Things learned about problems caused or opportunities generated may be fed back to the design of new alternatives, which themselves may be similarly tested.  One may get as sophisticated an analysis as the decisionmaking process demands.</p>\n<br/>\n<p>Figure 1 shows a decision point that asks whether the results from the micro- or macrohabitat models display cumulative or synergistic effects.  If they do, then network habitat analysis is the appropriate tool.  We are left, however, in a difficult bind.  We may not know a priori whether the effects are cumulative or synergistic unless some network-type questions are investigated as part of the scoping process.  The next several sections raise issues designed to alert the modeler to relevant questions necessary to address this paradox.</p>","language":"English","publisher":"National Ecology Center","publisherLocation":"Washington, D.C.","usgsCitation":"Bartholow, J.M., and Waddle, T.J., 1986, Introduction to stream network habitat analysis, ix, 242 p.","productDescription":"ix, 242 p.","numberOfPages":"251","costCenters":[],"links":[{"id":292742,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f707dee4b05ec1f2431bef","contributors":{"authors":[{"text":"Bartholow, John M.","contributorId":77598,"corporation":false,"usgs":true,"family":"Bartholow","given":"John","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":498974,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Waddle, Terry J.","contributorId":43430,"corporation":false,"usgs":true,"family":"Waddle","given":"Terry","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":498973,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Because of the physical and hydrologic characteristics of the watershed, major contributions of groundwater to stormflow are very unlikely. The large increase in dissolved chemical load observed at maximum river discharge required that extensive interaction with, and presumably penetration of, soils occurred within a few hours time.

The multicomponent system was simplified to two components by regarding all exchangeable cations other than strontium 90 as a single component. The binary ion-exchange parameter was a function of the variable, total ion concentration. A one-dimensional solute transport model was formulated to evaluate the time necessary for natural groundwater flow to remove the strontium 90 contamination plume from the groundwater system to the Pawcatuck River. The finite difference transport equations were solved sequentially for total ion concentrations, then strontium 90 concentrations. Clay-free quartz and feldspar sands at the study site have little potential for strontium 90 sorption, and high calcium, magnesium, and sodium concentrations compete for the few ion exchange sites. As the total ion concentration plume moves out of the system, ion exchange of strontium 90 increases, reducing the strontium 90 concentration in the groundwater.

To help assess the value of using such models to make predictions, a postaudit was conducted on a previously studied area in the Salt River and lower Santa Cruz River basins in central Arizona. A deterministic, distributed-parameter model of the ground-water system in these alluvial basins was calibrated by Anderson (1968) using about 40 years of data (1923–64). The calibrated model was then used to predict future water-level changes during the next 10 years (1965–74). Examination of actual water-level changes in 77 wells from 1965–74 indicates a poor correlation between observed and predicted water-level changes. The differences have a mean of 73 ft that is, predicted declines consistently exceeded those observed and a standard deviation of 47 ft. The bias in the predicted water-level change can be accounted for by the large error in the assumed total pumpage during the prediction period. However, the spatial distribution of errors in predicted water-level change does not correlate with the spatial distribution of errors in pumpage. Consequently, the lack of precision probably is not related only to errors in assumed pumpage, but may indicate the presence of other sources of error in the model, such as the two-dimensional representation of a three-dimensional problem or the lack of consideration of land-subsidence processes. This type of postaudit is a valuable method of verifying a model, and an evaluation of predictive errors can provide an increased understanding of the system and aid in assessing the value of undertaking development of a revised model.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.1986.tb00993.x","usgsCitation":"Konikow, L.F., 1986, Predictive accuracy of a ground-water model--Lessons from a postaudit: Groundwater, v. 24, no. 2, p. 173-184, https://doi.org/10.1111/j.1745-6584.1986.tb00993.x.","productDescription":"12 p.

Both Cu and Zn are essential algal micronutrients, cofactors in numerous biochemical processes. The availability of a nutrient or toxic substance can be significantly affected by precipitation. Methods for modeling the effects of adsorption–desorption reactions have been previously reviewed. Useful predictions of algal response require an understanding of the relative importance of these interactions (both magnitude and time dependence). Photoreduction and dissolution of Mn oxides by dissolved humic substances has been proposed as an important factor regulating dissolved Mn distribution in seawater. Photodegradation of iron (Fe) chelates also enhances Fe uptake by algae.

Moreover, groundwater flow in these environments appears to influence the evolution of certain hydrologic, geologic, and geochemical systems, may affect the accumulation of pertroleum and ores, and probably has a role in the structural evolution of parts of the crust. Such environments are also important in the context of waste disposal. This review attempts to synthesize the diverse contributions of various disciplines to the problem of flow in low-permeability environments. Problems hindering analysis are enumerated together with suggested approaches to overcoming them. A common thread running through the discussion is the significance of size- and time-scale limitations of the ability to directly observe flow behavior and make measurements of parameters. These limitations have resulted in rather distinct small- and large-scale approaches to the problem. The first part of the review considers experimental investigations of low-permeability flow, including in situ testing; these are generally conducted on temporal and spatial scales which are relatively small compared with those of interest. Results from this work have provided increasingly detailed information about many aspects of the flow but leave certain questions unanswered. Recent advances in laboratory and in situ testing techniques have permitted measurements of permeability and storage properties in progressively “tighter” media and investigation of transient flow under these conditions. However, very large hydraulic gradients are still required for the tests; an observational gap exists for typical in situ gradients. The applicability of Darcy's law in this range is therefore untested, although claims of observed non-Darcian behavior appear flawed. Two important nonhydraulic flow phenomena, osmosis and ultrafiltration, are experimentally well established in prepared clays but have been incompletely investigated, particularly in undisturbed geologic media. Small-scale experimental results form much of the basis for analyses of flow in low-permeability environments which occurs on scales of time and size too large to permit direct observation. Such large-scale flow behavior is the focus of the second part of the review. Extrapolation of small-scale experimental experience becomes an important and sometimes controversial problem in this context. In large flow systems under steady state conditions the regional permeability can sometimes be determined, but systems with transient flow are more difficult to analyze. The complexity of the problem is enhanced by the sensitivity of large-scale flow to the effects of slow geologic processes. One-dimensional studies have begun to elucidate how simple burial or exhumation can generate transient flow conditions by changing the state of stress and temperature and by burial metamorphism. Investigation of the more complex problem of the interaction of geologic processes and flow in two and three dimensions is just beginning. Because these transient flow analyses have largely been based on flow in experimental scale systems or in relatively permeable systems, deformation in response to effective stress changes is generally treated as linearly elastic; however, this treatment creates difficulties for the long periods of interest because viscoelastic deformation is probably significant. Also, large-scale flow simulations in argillaceous environments generally have neglected osmosis and ultrafiltration, in part because extrapolation of laboratory experience with coupled flow to large scales under in situ conditions is controversial. Nevertheless, the effects are potentially quite important because the coupled flow might cause ultra long lived transient conditions. The difficulties associated with analysis are matched by those of characterizing hydrologic conditions in tight environments; measurements of hydraulic head and sampling of pore fluids have been done only rarely because of the practical difficulties involved. These problems are also discussed in the second part of this paper.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR022i008p01163","usgsCitation":"Neuzil, C.E., 1986, Ground-water flow in low permeability environments: Water Resources Research, v. 22, no. 8, p. 1163-1195, https://doi.org/10.1029/WR022i008p01163.","productDescription":"33 p.","startPage":"1163","endPage":"1195","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":224071,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"22","issue":"8","noUsgsAuthors":false,"publicationDate":"2010-07-09","publicationStatus":"PW","scienceBaseUri":"505a1484e4b0c8380cd54a86","contributors":{"authors":[{"text":"Neuzil, Christopher E. 0000-0003-2022-4055 ceneuzil@usgs.gov","orcid":"https://orcid.org/0000-0003-2022-4055","contributorId":2322,"corporation":false,"usgs":true,"family":"Neuzil","given":"Christopher","email":"ceneuzil@usgs.gov","middleInitial":"E.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":369953,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This model provides a means of understanding the interaction of hydrophobic pollutants with humic materials. In this model, it is proposed that the humic materials in soils and sediments consist of a number of different oligomers and simple compounds which result from the partial degradation of plant remains. These degradation products are stabilized by incorporation into humic aggregates bound together by weak bonding mechanisms, such as hydrogen bonding, pi bonding, and hydrophobic interactions. The resulting structures are similar to micelles or membranes, in which the interiors of the structures are hydrophobic and the exteriors are hydrophilic. Hydrophobic compounds will partition into the hydrophobic interiors of the humic micelles or \"membrane-like\" structures. ?? 1986.","language":"English","publisher":"Elsevier","doi":"10.1016/0169-7722(86)90005-7","issn":"01697722","usgsCitation":"Wershaw, R., 1986, A new model for humic materials and their interactions with hydrophobic organic chemicals in soil-water or sediment-water systems: Journal of Contaminant Hydrology, v. 1, no. 1-2, p. 29-45, https://doi.org/10.1016/0169-7722(86)90005-7.","productDescription":"17 p.","startPage":"29","endPage":"45","numberOfPages":"17","costCenters":[],"links":[{"id":223691,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e4abe4b0c8380cd46815","contributors":{"authors":[{"text":"Wershaw, R.L.","contributorId":62223,"corporation":false,"usgs":true,"family":"Wershaw","given":"R.L.","affiliations":[],"preferred":false,"id":369878,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We hypothesize that the detergents form two distinct plumes, which consist of alkyl benzene sulfonates (ABS) detergents and linear alkyl sulfonates (LAS) and sodium dodecyl sulfate (NaLS) detergents. The ABS detergents were deposited from approximately 1940 through 1965, when ABS detergents were banned. From 1965 to the present, LAS and NaLS detergents were in the sewage. The ABS detergents appear to be transported in the aquifer at the same rate as the specific conductance (major cations and anions) and boron, which are currently used as conservative tracers of the plume of contaminated groundwater. There appears to be little or no biological degradation of the ABS detergents in the aquifer, based on their concentration in the plume. On the other hand, the LAS and NaLS detergents have degraded rapidly and have been detected only 0.6 km down gradient. The roleof the detergents in the transport of other organic compounds in the plume is nuclear. There is a separation of the ABS detergent plume and the volatile organic compound plume; however, the time of entry of the detergents and the volatile organic compounds is unknown. Therefore, it is not possible to conclude on the interaction of these two classes of compounds.&nbsp;</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0169-7722(86)90013-6","issn":"01697722","usgsCitation":"Thurman, E., Barber, L., and LeBlanc, D., 1986, Movement and fate of detergents in groundwater: A field study: Journal of Contaminant Hydrology, v. 1, no. 1-2, p. 143-161, https://doi.org/10.1016/0169-7722(86)90013-6.","productDescription":"19 p.","startPage":"143","endPage":"161","numberOfPages":"19","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":224229,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5f0ee4b0c8380cd70d47","contributors":{"authors":[{"text":"Thurman, E.M.","contributorId":102864,"corporation":false,"usgs":true,"family":"Thurman","given":"E.M.","affiliations":[],"preferred":false,"id":369801,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barber, L.B.
