Subsurface Irrigation Research In Arkansas, John P. Hoskyn, Billy B. Bryan

Arkansas Water Resources Center Technical Reports

A pilot study conducted in 1963 indicated that (1) cotton yields could be increased by subirrigation, (2) drilled orifices were unsatisfactory because of internal plugging caused by burrs and drilling particles, and (3) operating pressures of 5 and 10 psi were excessive, and 5 psi probably should be considered as an upper-limit pressure. A greenhouse study of a subirrigation system indicated that 2 psi should, in general, for in-wall orifices, be considered as a lower-limit pressure when orifices are built into the pipe wall. The greenhouse study also indicated that a placement depth of 12 inches was preferable to 18 …

Barramundi are widely distributed in rivers and estuaries in the semi-tropical and tropical regions of the Indo- Pacific from South China to the Persian Gulf and along the coast of northern Australia. The limiting factors to the distribution appear to be temperature and salinity.

Soil Conservation Land Use, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 4

MANY things are blamed for soil erosion—including storms, fires, cost-price squeezes, ploughing downhill and rabbits. But the basic factor is the risk involved in the way the land is used.

It is therefore vital that everyone—not only farmers—should begin their thinking about soil conservation from the land use aspect (of which special practices such as contouring, are a small though spectacular part.)

Water Quality Telemetry, Final Progress Report, Duard S. Woffinden, Allen D. Kartchner

Reports

Water quality standards are now part of the legal code set up to control water pollution. In order to ascertain that these standards are being met, it is mandatory to monitor any river system over which control must be maintained. For optimum, usefulness, data on the monitored variables should be available on a real time basis at any time throughout the 24-hour day. Remote sampling stations and a telemetry link represent the most practical means of accomplishing this end. A water quality monitoring system utilizing radio telemetry has been developed at the Utah Water Research Laboratory (UWRL). The system consists …

Influence Of Mountain Groundwater On Streamflow, Bi-Huei Wang, Roland W. Jeppson

Reports

This investigation has determined the quantities of water stored as groundwater in the three watersheds in Utah, Logan River upstream from State Dam, South Fork Ogden River upstream from Huntsville, and Weber River upstream from Oakley. The proportion of the total streamflow contributed from this groundwater storage has been determined from past streamflow records, and the knowledge obtained from the analysis of groundwater contribution to streamflow has been utilized in developing water supply forecasting techniques and procedures. The first phase of the study dealt with theory and methods from separating the groundwater component from the total streamflow hydrograph. The method …

Finite Difference Solutions To Free Jet And Confined Cavity Flows Past Disks With Preliminary Analyses Of The Results, Roland W. Jeppson

Reports

A number of solutions are obtained to ideal axisymmetric flow past cavitating disks for both cases of a free surface jet and flow confined in a constant radius conduit. Finite difference methods are utilized in obtaining the solutions from an inverse formulation which considers the velocity potential, and Stokes’ stream function, as the independent variables and the radial and axial dimensions, r and z, as the dependent variables. The resulting inverse boundary value problem for r, for which the basis solution is obtained, is nonlinear. The solution technique uses a Newton-Raphson iteration to evaluate the implicit finite difference operator at …

Snowmelt Simulation, J. Paul Riley, Duane G. Chadwick, Keith O. Eggleston

Reports

The rapid growth in recent years of a variety of demands upon available water resources has lead to an increasing interest in more fundamental approaches to the science of hydrology. Accompanying this growth has been a need for an increased understanding of the snowmelt process. A completely adequate description of the entire physical process of snowmelt under all conditions is not yet available. The complex interrelated and variable nature of the snowmelt processes that occur simultaneously complicate the problem. A preliminary mathematical model of the snowmelt process has been developed in which processes such as pack settlement rates and energy …

Electronic Analog Computer Simulation Of The Paez-Pedraza Region Of Venezuela, J. Paul Riley, V. V. Dhruva Narayana, Kousoum S. Sakhan

Reports

Recently governments and universities in many South American countries have shown considerable interest in a planned and orderly development of available water resources. A case in point is the preliminary study reported in which the problem is approached by utilizing a general mathematical model of the hydrologic system. Specifically, the study involves simulation by means of an electronic analog computer of the hydrology of the Paez-Pedraza region of south western Venezuela. The various processes within the model are linked by the continuity-of-mass principle, which requires a hydrologic balance at all points. The analog computer is ideally suited to the solution …

Analog Computer Simulation Of The Runoff Characteristics Of An Urban Watershed, V. V. Dhruva Narayana, J. Paul Riley, Eugene K. Israelsen

Reports

In the syntheses of hydrograph characteristics of small urban watersheds, the distribution of water among the various phases of the runoff process is attempted by the concept of equivalent rural watershed. The urban parameters considered in the study are percentage impervious cover and characteristic impervious length factor. A mathematical model is developed for the equivalent rural watershed with precipitation as input. The hydrograph of outflow is obtained by chronologically deducting the losses due to interception, infiltration, and depression storages from precipitation and then routing through the watershed storage. This mathematical procedure is programmed on an analog computer and is tested …

A Perspective Of Contemporary Water Planning And Management Problems In Utah, Jay M. Bagley

Reports

I should like to discuss what I consider to be a few major problems Utah faces in connection with water and its development. Time will not permit great detail or breadth of discussion. The points I should like to discuss best can be made by first setting some hydrologic scenery. Actually, although hydrologic considerations provide the central melody to planning for water resources development, there are many socio-politico-legal-economic variations on the theme. My approach will be to remark briefly on thie environment in which today's planning must take place, provide some broad hydrologi guideposts, and with this backdrop select a …

Analog Computer Solution Of The Unsteady Flow Equations And Its Use In Modeling The Surface Runoff Process, Utah Water Research Laboratory

Reports

The flow of water on a watershed is usually unsteady and spatially varied, but can be adequately portrayed by the equations of momentum and continuity, commonly referred to as the unsteady flow equations. Because these equations are quasi-linear, hyperbolic, partial differential equations, they are not easily amenable to solution. Analog computer model~ of surface runoff generally have been based on simplified forms of these equations. As an improvement of those models, an analog computer solution is presented here for the unsteady flow equations. The solution involves the conversion of the partial differential equations in to a differential-difference system, and a …

The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates

KWRRI Research Reports

Development of a large multi-purpose reservoir within the area of their jurisdiction may affect property ta.x revenue and expenditure of county governments and school districts. Privately owned land sold to a federally sponsored reservoir is not subject to property taxes because of the doctrine of intergovernmental immunity. Local officials often assume that this loss of assessment will reduce their tax revenue and thereby their fiscal ability to provide an acceptable level of government services. They may also expect the influx of construction workers or the disruption of existing facilities to increase the cost of providing these services. The study approaches …

Patterns Of Land Use Change Around A Large Reservoir, Billy R. Prebble

KWRRI Research Reports

Reservoirs are built to control floods, provide water for irrigation and municipal supply, generate electric power, augment low flows for navigation and water quality control, and provide improved fishing and recreation opportunity. A reservoir is justified if the benefit it provides to society exceeds the cost to develop it. Much research has been done to determine the benefit of a water resources development to society as a whole. Some research has explored the benefit of such a facility to a region. Very little research exists on the effects of a reservoir on the immediately surrounding area.

It seems reasonable that …

Economic Development Of Areas Contiguous To Multipurpose Reservoirs: The Kentucky-Tennessee Experience, Michael B. Hargrove

KWRRI Research Reports

This study analyzes the effects of multi-purpose reservoir projects on the economic development of areas contiguous to the dam and reservoir. The study concentrates on the development potential in a humid region where the provision of agricultural water is not critical to the economy. Can a reservoir project be a major part of a development program for a local area? How can the favorable effects of the project on the contiguous area be increased? These questions are answered by this study.

The study is divided into three major phases. The first phase is a theoretical analysis of the determinants of …

The Persistence Of Pesticides In Impounded Waters, Robert A. Lauderdale

KWRRI Research Reports

The purpose of this study was to investigate the persistance of the insecticides aldrin, dieldrin, chlordane, and DDT in water. A small drainage area was sprayed with these compounds, and the insecticides were collected in the runoff water from the area. Laboratory experiments were performed to determine the effectiveness of aeration, adsorption on silt, and adsorption on algae in removing the pesticides from water.

All of the pesticides were found in samples of water collected from the area for the full period of the tests. The amounts which were found in a small pond into which the surface water drained …
