Phosphorus Distribution In The Bottom Sediments Of Hyrum Reservoir, Kirk L. Schmalz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The distribution of phosphorus in the sediment of Hyrum Reservoir was studied by collecting and analyzing 84 sediment samples for total, inorganic, organic, and water-soluble phosphorus.

Sample locations were mapped by triangulation and sediment phosphorus distribution maps were made. Sediment analysis showed average total phosphorus content of 755 micrograms per gram, with organic phosphorus composing approximately 97 percent of total phosphorus.

Sediment samples showed variability in phosphorus content which precluded identification of point sources of phosphorus input to the reservoir. Several areas of comparatively higher phosphorus content in the sediments were shown with isopleth maps.

An estimate of the extent …

Computer Simulation Of Urban Runoff Characteristics Within Salt Lake County, Robert Newman Parnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A hybrid computer program is developed to simulate the outflow hydrographs of two urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a checkpoint for comparing the observed and the simulated final outflow hydrographs.

The outflow hydrographs for each subzone of the two watersheds were obtained by abstracting interception, infiltration and depression storage from each subzone hyetograph. The outflow of the subzones were routed to the Jordan River, the final outflow point of the two watersheds. The final hydrographs of the watersheds were combined and compared with the gaged flow.

The uniquenesses of this …

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 …

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

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, …

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. …
