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 …

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 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 …

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 …

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 …

Cutthroat Flow Measuring Flumes For Flat Gradient Channels, Gaylord V. V. Skogerboe

Reports

The cutthroat flume can operate either as a free or submerged flow structure. Submerged flow calibration curves and free flow equations have been developed. Rectangular cutthroat flume sizes of 1, 2, 3, 4, and 6 feet were studied and tested in the laboratory. Trapezoidal cutthroat flumes having zero (or V-shaped), 6-inch, and 12-inch throat widths were calibrated. The value of transition submergence is listed for each of the rectangular and trapezoidal cutthroat flumes. The most obvious advantage of a cutthroat flume is economy, since fabrication is facilitated by a flat bottom and removal of the throat section. Another advantage is …

Economic Analysis Of Alternative Flood Control Measures, L. Douglas James, Thomas M. Rachford, James Ray Villines, Clyde R. Dempsey, James Norris Cline, Carlos Fix Miller

KWRRI Research Reports

Within the last few years, the growing realization that an effective flood control program must include non-structural measures (land use management and flood proofing) has resulted in Presidential Executive Order 11296 requiring Federal agencies to seek the optimum combination of structural and non-structural measures for flood control. The requirement has created a dilemma. No methodology is available for systematic evaluation of alternative combinations of structural and non-structural measures. Prospective procedures are too time consuming to be feasible under current financial and manpower limitations.

The only way out is to perform much of the planning process by digital computer. With this …

Ecological Study Of The Effects Of Strip Mining On The Microbiology Of Streams, Ralph H. Weaver, Harry D. Nash

KWRRI Research Reports

The microflora of Cane Branch of Beaver Creek in McCreary County, Kentucky, which drains an area that was strip-mined between 1955 and 1959, was studied and compared with that of Helton Branch which drains a comparable area where there has been no mining. Differences include: the establishment of Ferrcbacillus ferrooxidans, for which procedures were developed for direct colony isolation from the stream; fewer saprophytic bacteria; more numerous and more diversified filamentous and unicellular fungi; and characteristic differences in algal flora. Representatives of 42 genera of filamentous fungi were identified. Of these, 21 were isolated only from Cane Branch. Representatives of …

Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock

KWRRI Research Reports

In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of …

Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …

The purpose of this study was to find a way to evaluate the esthetic and recreational potential of small streams and their watersheds. Research was limited to naturalistic streams with drainage areas under 100 square miles and located within 25 miles of a city. A methodology, based on some previous work of the U.S. Soil Conservation Service and the principles or concepts of terrain analysis, land use planning, value Judgment philosophy and the economics of outdoor recreation, was developed and applied in detail to two streams (Boone and Jessamine Creeks) near Lexington, Kentucky.

Evaluations were made of the streams' potential …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

The Ord River Regeneration Project. 3. Eight Years Of Progress, K Fitzgerald

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

REGENERATION of degraded areas in regions of marginal rainfall is a slow process under the best of conditions, but on the Ord River Catchment, where much top-soil had been removed, the problem was unusually severe.

In many areas top-soil will have to be rebuilt before vegetation can be re-established.

This will be a long, slow process and regeneration will proceed through gradual plant succession from the "pioneer" annual species through to the permanent and more productive perennial species needed for a stable catchment area.
