The development and allocation of the water resourcse within a state require water planners to prepare plans far in advance of the actual time new facilities are required. It is not easy to identify and evaluate all the possible alternatives for providing water which incorporate broad objectives such as economic efficiency, social welfare, regional development, recreation benefits, and conservation of environment. Water resources development entails the modification of a natural hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system are relatively …

Calibration Of Parshall Flumes With Non-Standard Entrance Transitions, Cheng-Lung Chen, Calvin G. Clyde, Min-Shoung Chu, Chi-Yuan Wei

Reports

The 9-ince and 18-inch Parshall flumes with the throat section installed level with the bottom of an incoming pipe were tested. The measured discharges for given flow depths (free flow) or differences in flow depths (submerged flow) were found to deviate quite significantly fromt he computed standard Parshall flume disharges at both low and high flow rates. New empirical formulats have been developed to take such deviations into account. It is noted that values of the coefficients and exponents contained in the new formulas depend on the throat size of the flume and the slope of the incoming pipe. Calibration …

Water Resources Planning To Satisfy Growing Demand In An Urbanizing Agricultural Region, Thomas C. Anderson

Reports

Although it is condeded that an adequate supply of water is essential to economic growth and development, what constitutes an "adequate" supply is often controversial and difficult to determine. The problem can be solved by applying basin economic concepts: determining the value of water be estimating its supply and demand. This report demonstrates one method for doing this. The theory of the demand for irrigation water and its empirical application are discussed. An example problem based on data from one of the sub-regions of the study area (the Jordan River Basin of Utah) is presented to illustrate the method. The …

Analysis Of Water Reuse Alternatives In An Integrated Urban And Agricultural Area, A. Bruce Bishop, David W. Hendricks

Reports

Intoduction

The growing demands on our existing water supplies and the current problems of water shortage emphasize the need for a comprehensive approach to analysis and planning of water reuse. The primary focus, heretofore, has been on the treatment technology for achieving water reuse.

The concept of reuse, however, should be broadened to consider a totally integrated urban and agricultural system. This necessitates a systems analysis where water reuse, together with all other water dispositions, is considered in the context of its contribution to the total water resources pool of a region.

The components of the water resource system are …

Finite Difference Solutions Of Axisymmetric Infiltration Through Partially Saturated Porous Media, Chi-Yuan Wei, Roland W. Jeppson

Reports

Solutions are obtained to the problem of steady-state partially saturated infiltration of moisture applied over a horizontal source circle which moved through homogeneous soils toward a water table. A commonly accepted relationship between relative permeability and capillary pressure has been utilized in conjunction wit Darcy’s law to formulate the mathematical model. The solutions have utilized an inverse formulation and have been obtained by finite difference. The inverse formulation considers the magnitudes of the cylindrical coordinates r and z as the dependent variables and the potential function and the Stokes’ stream function as the independent variables (i.e the problem is solved …

The Behavior Of Pvc Pipe Under The Action Of Water Hammer Pressure Waves, Gary Z. Watters

Reports

Introduction: Hydraulic transients, commonly referred to as water hammer, occur in a hydraulic system whenver the velocity of flow in any one of the pipes in the system is caused to change. The magnitude of the pressure waves generated by a given change in velocity depends on the geometry of the pipe system, the magnitude of the velocity change and the elastic wave velocity in the system componenets. In turn, the elastic wave velocity depends on the modulus of elasticity of the fluid and the pipe material, the size and thickness of the pipe, the method by which the pipe …

Inverse Solutions To Three-Dimensional Free Surface Potential Flows, Roland W. Jeppson

Reports

Methods are developed and defined for obtaining numerical solutions to three-dimensional, free surface, invisvid, incompressible fluid flows and three-dimensional free surface Darcian flow in porous media. Since those boundaries consisting of free surface are unknown a priori, a solution to the space boundary value problem resulting from a formulation in the physical space is very difficult, if not impossible, to obtain. Consequently, the methods described herein are based on a formulation in a space defined by a potential function and two mutually orthogonal stream surfaces whose intersections define the streamlines of the flow. In this space the positions of free …

The Effect Of Carbon On Algal Growth--Its Relationship To Eutrophication, Joel C. Goldman, Donald B. Porcella, Joe E. Middlebrooks, Daniel F. Toerien

Reports

Introduction: Natural and cultural eutrophication (enrichment with nutrients) frequnetly results in excessive algal growths thereby reducing the beneficial uses of surface waters (Hasler, 1947; Thomas, 1955, Edmondson et al., 1956, Oswald and Golueke, 1966, Skulberg, 1967, Mackenthun et al., 1968, Goldman and Armstrong, 1969, McGauhey et al., 1968,1969, 1970a, 1970b). Recent reviews emphsize that the prevention of further reduction in the quality of water resources requires the implementation of effective control measures (Goldman, 1965, Steward and Rohlich, 1967, Middlebrooks et al., 1969, Rohlich, 1969). Effective control of cultural eutrophication must involve the manipulation of those factors which affect algal growth, …

Development Of A Procedure For Determining Spacial And Time Variations Of Precipitation In Venezuela, Luis E. Ramirez

Reports

An analysis of the influence of the length of the record in the reliability of mean values of precipitation was made for the Caracus-Cagigal Station in Venezuela. Ten series of values were obtained for 10, 15, 20, 25, 30, and 35-year periods, extracted for sliding intervals for the overall record of 75 years. The reliability of mean values computer from Figure 3 was quite low for 10, 15, and 20- year periods. The long term record means had higher reliability, increasing with the number of years in the records, but the differences are not important in terms of accuracy. Precipitation …

The Detection Of Magnetic Fields Caused By Groundwater, Duane G. Chadwick, Larry Jensen

Reports

Perturbations on the earth’s magnetic field may coincide with the existence of groundwater. Theoretical calculations are made showing how and to what extent this effect may exist. The suggestion is also made that water dowsers may get a dowsing reaction as a result of entering a change in magnetic gradient. Tests were conducted to determine the statistical significance of dowsing reactions obtained by separate individuals dowsing in a common test area. Approximately 150 people participated in the experiment over a period of one year. Chi-square tests showed considerable statistical significance. Virtually all people tested experienced dowsing reactions though most of …

Extending Utility Of Non-Urban Water Supplies, Jay M. Bagley

Reports

Extending the utility of an existing water supply in any river basin suggests a management-planning approach under three general guiding principles: (1) minimize depletions wherever possible (thereby maintaining a greater manageable quantity with subsequent potential to satisfy more uses); (2) generally preserve, protect, and improve water quality (thereby retaining its itility for use by a wider variety of potential users); and (3) make carefully considered allocations (thereby assuring multiples duty, more optimal sequencing, and shifts in use to conform to current and projected soil preferences). There are many technological and managerial techniques that can be employed to implement these principles. …

Reports

Criterion have been developed for designing a stilling basin to serve as a transition from closed conduit flow to open channel flow for a fully submerged pipe outlet. The unique feature of the stilling basin is the short-pipe energy dissipater so located and designed as to provide maximum energy dissipation for the basin configuration. The expanding characteristics of a submerged jet were used in establishing the length of the stilling basin. The unsteadiness of the water surface and the relative boil height in the model basin were used as the criteria for evaluating the effectiveness of the structure for energy …

Hydrograph Synthesis For Watershed Subzones From Measured Urban Parameters, Joseph B. Evelyn, V. V. Dhruva Narayana, J. Paul Riley, Eugene K. Israelsen

Reports

An analog computer program was developed to simulate the outflow hydrographs at four locations within the 38th Street Waller Creek urban watershed at Austin, Texas. Actual outflow was gaged at the final outlet of the watershed. This provided a checkpoint for comparing the simulated and observed final outflow hydrographs. The outflow hydrographs for each subzone were obtained by chronologically abstracting interception, infiltration, and depression storage from their precipitation hyetographs. These outflow hydrographs were then routed through Waller Creek channel to obtain the hydrographs at the four desired locations.
