Modeling Soil Water Contents And Their Effects On Stream Flow In Kentucky, Grant W. Thomas, Ronald E. Phillips, David E. Radcliffe, Scott Shepard

KWRRI Research Reports

Soil water contents of eight important soil series in Kentucky were measured periodically during the summer growing season for four years, 1977 through 1980. The soils divided into three groups according to their behavior. The first group (Maury and Crider) is well-drained and never showed excess water above field capacity at any time during the four seasons. The second group (Zanesville, Lowell, Calloway, Grenada and Shelbyville) showed perched water tables at times, especially during the early part of the growing season. The third group was represented by the Huntington soil which has a permanent water table.

The in-situ field capacity …

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 …

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

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 …

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 …

Dickey-Lincoln School Lakes Project Economic Analysis Study, New England Division, United States Army Engineer Division, Acres American Incorporated

Dickey-Lincoln School Lakes Project

The purpose of this study was to perform an economic assessment of the Dickey-Lincoln School Lakes Project. This was accomplished by simulating the New England electrical supply system with and without the project and making a comparison of the resultant production costs.

Simulating The Water Requirements And Economic Feasibility Of Corn In The Midwest, Wendi L. Palmer, B. J. Barfield, M. E. Bitzer, C. T. Haan

KWRRI Research Reports

An evaluation of the economics of supplemental irrigation when using a surface water supply must be site specific in order to account for variations in soil moisture holding capacity, watershed area supplying the runoff, climatic conditions, and proposed irrigation management procedures.

With the use of farm specific simulation models to determine grain yields, availability of irrigation water, and economic expenditures involved in irrigation, an economic evaluation of supplemental irrigation can be performed, In the model presented in this report, the Duncan SIMAIZ model is used to predict grain yields using long-term daily weather information. SIMAIZ also determines irrigation water demand …

Evaluation Of Wastewater Filtration, Bryant L. Benth, E. Joe Middlebrooks, Dennis B. George, James H. Reynolds

Reports

Tertiary filtration of secondary wastewater is frequently used to improve wastewater treatment plant effluent quality. Four experimental filter columns were operated at the Preston, Idaho, Wastewater Treatment Plant to evaluate the effectiveness of granular media, gravity filtration. The Preston plant is a trickling filter secondary treatment plant and services a population of approximately 3600 people. Four filter medium configurations were studied. Multi-media, dual-media, and single-media beds were constructed with the following media configurations: (1) coal-sand-garnet; (2) coal-sand; (3) sand-garnet; and (4) all sand. The filters were operated at two hydraulic loading rates. Effluents from the primary clarifier, trickling filter, and …

Erosion Inhibitor Performance Evaluation Under Simulated Wind And Rain, C. Earl Israelsen, Eugene K. Israelsen, William N. Mcneill

Reports

Introduction: Increasing public awareness of the desireability of protecting the environment from soil erosion caused by wind and water has centered attention on large construction projects such as highways and housing subdivisions, as well as on individual building sites and parking lots. If unattended, sediment produced from these areas pollutes surface water, restricts drainage, fills reservoirs, damages adjacent land, and upsets the natural ecology of lakes and streams. The search continues for products and practices that will prevent of lessen the amount of sediment leaving construction sites. Products currently in use include chemical as well as organic materials, and they …

Fielding Ditch Pipeline Computer Simulation Study, Calvin G. Clyde, J. Paul Tullis, Roland W. Jeppson

Reports

The Fielding Ditch Company Pipeline is almost 3 miles long and supplies irrigation water under low pressure to adjacent fields through 33 turnouts along its length. The 24-inch non-reinforced concrete pipeline began to experience repeated structural failures soon after it was placed in operation. This study was done for the Soil Conservation Service by the Utah Water Research Laboratory to gather field data on the pipeline operating characteristics, to analyze the hydraulic transients in the pipeline with the help of a computer simulation model, and to suggest modification to protect the pipeline from future failures caused by transient pressures.
