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 …

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 …

A Computer Model Of The Quantity And Chemical Quality Of Return Flow, Jimmie L. Thomas, J. Paul Riley, Eugene K. Israelsen

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. …
