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 …

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 …

Simulation Of The Hydrologic-Economic Flow System In An Agricultural Area, Murland R. Packer, J. Paul Riley, Harold H. Hiskey, Eugene K. Israelsen

Reports

Like the allocation of water resources among water users, the distribution of allocated water to the subusers requires an estimate of the economic costs and benefits from a number of distribution alternatives. The most satisfactory solution maximizes the benefit cost ratio. This study is based on the premise that equitable water distribution to agricultural subusers can be more easily accomplished through the use of a technique to predict the marginal value of agricultural water. A hydro-economic model is formulated to distribute the water supply to the crops and to determine the unit value of water for the given supply. By …

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 …

Development And Control Of Licking Behavior In The Guinea Pig (Cavia Porcellus), Jack R. Alvord

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four non-licking guinea pigs were reinforced with water for successive approximations to licking an operandum feeder. Once all subjects had obtained their total liquid intake for a three-week period by licking, an optimum deprivation schedule was determined.

Fixed ratio and variable interval schedules were found to affect licking behavior of the guinea pig in a similar way as with the rat, mean lick rate of guinea pigs being slightly lower than that of the rat. Precise control over the onset and offset of licking was demonstrated through discrimination training.
