Comparing Three Water Quality Sampling Techniques For Measuring Non-Point Source Pollution In Forest Streams, R. Scott Beasley

Arkansas Water Resources Center Technical Reports

Coshocton wheel samplers, ISCO pumping samplers, and single stage samplers were compared on each of three small (5-6 ha), forested watersheds in the Ouachita Mountains of central Arkansas. The objective of the comparisons was to evaluate the performance of each sampling method in providing reliable samples for measuring concentrations of total suspended solids (TSS). H-flumes and water level recorders provided stream discharge data; a network of recording and non-recording raingages provided preciptation measurements. Rainfall and storm discharges during the study period were unusually low. No samples were collected by the single stage samplers. They appear unsuited for use on small …

Algorithms For Pipe Network Analysis And Their Reliability, Don J. Wood

KWRRI Research Reports

Algorithms for analyzing steady state flow conditions in pipe networks are developed for general applications. The algorithms are based on both loop equations expressed in terms of unknown flowrates and node equations expressed in terms of unknown grades. Five methods, which represent those in significant use today, are presented. An example pipe network is analyzed to illustrate the application of the various algorithms. The various assumptions required for the different methods are presented and the methods are compared within a common framework.

The reliabilities of these commonly employed algorithms for pipe network analysis are investigated by analyzing a large number …

Mathematical Model For Water Quality In Streams Impacted By Point And Nonpoint Source Pollution, Michael E. Meadows

KWRRI Research Reports

Modeling the impacts of stormwater runoff on small streams, requires that the prediction model has the capability of simulating the behavior of the hydrologic and water quality components of the stream system. Development of such a model involves coupling the equations for pollutant transport during unsteady flow with the appropriate flood routing equations. The decision on which equations to choose requires a full understanding of the pollutant transport and hydrograph dispersion processes.

This research was undertaken to develop a rigorous theoretical evaluation of the pollutant transport and hydrograph dispersion processes during unsteady flow, and to recommend a suitable model for …

Report No 41 - A Survey Method For Identifying Roadside Flora Suitable For Conservation In Western Australia, John K. Scott

Fisheries Research Reports

A survey method for identifying flora suitable for conservation alongside roads in south-western Australia was derived from an examination of characteristics of road verges. Two roads, from Midland to Toodyay and from Armadale to Bunbury, were examined. Width of verge, weed cover, soil disturbance, vegetation structure, presence of public utilities, evidence of fire and the type of adjoining land were measured at one mile (1.6 km) intervals on both sides of the road. Also recorded were aesthetic qualities such as stands of beautiful trees and sites of special interest, e.g. the presence of rare plants.

The White Perch, Marone Americana (Gmelin) In Nebraska, Gene Zuerlein

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The white perch, Morone americana (Gmelinl, is a member of the Percichthyidae family. It is a euryhaline species that is common along the northern Atlantic coast south to the Carolinas. Marine, estuarine and freshwater ecosystems with salinities ranging from 5 to 18 percent have been known to support white perch (Mansueti 1964). The species is semianadromous, making spawning runs up coastal streams. It commonly becomes completely landlocked in ponds and reservoirs of its native range where it spawns successfully. This species has been known as a game fish to generations of New England fishermen, but when stocked in landlocked waters …

A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer

Reports

Introduction: Scrubber wastes obtained in an affort to limit air pollution generated by coal-fired pwoer plants may contribute to another possible sources of pollution. To date, scrubber wastse have been in a liquid phase which causes disposal problems partially due to the liquid characteristics. The use of solid scrubber wastes and the land deposition of such wastes is proposed. The feasibility of solid scrubber wastes disposal in landfills is under question. The primary area of concern is the effect that water percolation through such wastes would have on groundwater quality parameters. Contamination could result either as precipitation travels downward through …

After presenting the relevant physiographic, geologic, and hydrologic characteristics of the various regions of Utah and discussing how these relate to groundwater contamination in general, representative groundwater quality hazards in 32 sites or regions in Utah are presented. A very wide range of hazards to groundwater quality was found to exist. These cases cover the range …

Energy Siting In Utah: A Programming Model, Donald L. Snyder, John E. Keith, Terrence F. Glover, Gene L. Wooldridge

Reports

Using a conceptual model of a multiple-product firm, the necessary conditions for an optimal input and output allocation were determined for a region constrained by resource availabilities and/or policy constraints. A linear programming model was developed to deteremine the optimal allocation of water between agricultural and coal-fired electrical generating entities as well as the trade offs which could occur if electrical generation were increased. Other areas of potential trade offs such as coal source restrictions and air quality regualtions were also examined. Coal mining and transportation costs were included as were SO2, Nox, and particulate emission rates on a coal …

A User's Manual For Computer Programs Used In: Model Choice: An Operational Comparison Of Stochastic Streamflow Models For Droughts, W. Robert James, David S. Bowles, Nath T. Kottegoda

Reports

The rapid development of stochastic or operational hydrology over the past 10 years has led to the need for some comparative analyses of the currently available long-term persistence models. Five annual stochastic streamflow generation models (autoregressive, autoregressive-moviing-average (ARMA), ARMA-Markov, fast fractional Gaussian noise, and broken line) are compared on their ability to preserved drought-related time series properties and annual statistics. Using Monto Carlo generation procedures and comparing the average generated statistics and drought or water supply properties, a basis is established to evaluated model performance on four different Utah study streams. A seasonal disaggregation model is applied to each of …

Update On Estimation Of Water Surface Elevation Probabilities For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield

Reports

The techniques of operational hydrology, employing an autoregrssive moving average (ARMA (1,0) model were used to replicate historical patterns of streamflow into, precipitation on, and evaporation from the Great Salt Lake. The results were combined with a lake water balance model to simulate lake stage sequences beginning with known initial conditions and extending up to 125 years into the future and used to generate probability distributions for future lake stages. Starting with a spring 1980 high stage of 4200.45 ft msl, the best estimate is that the 1981 spring high will be 4200.19, but there is one change in four …

Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen

Reports

The Sevier River Basin is a water short basin wherein upstream diversions not consumptively used become the water right for downstream users. The diversion-return cycle occurs several times as the stream travels from its mountain source areas to the terminal lake at the lower end of the basin. This study dealt with the proposed implementation of conservation measures which would wawste less diverted water and allow for irrigation of additional acres. The objective was to predict the hydrosalinity impacts of the implementation of these measures. The results indicated that increased consumptive use in the upper areas would decrease the water …
