Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter

Reports

This report reviews activities on this project since the Progress Report, Part IV, June 1961.

The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.

Most of the routine work on the project during the summer was done by …

A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil

Reports

Many attempts have been made to derive mathematical expressions relating evaporation and evapotranspiration, or consumptive use, to climatological data. IN the United States, the Blaney-Criddle formula is probably the best known for estimating consumptive use (2 and 3). Blaney (1) has also suggested that this formula is suitable for estimating evaporation as measured with a Weather Bureau pan. Other well known formulas are the Penman formulas (10), the Thornthwaite formula (15) and the Hargreaves formulas (8). Halkias, Beihmeyer and Hendrickson (6) suggest that water requirements of crops can be determined from atmometer data. Lowry and Johnson (() in an early …

Model Analysis Of Spillway And Stilling Basin Of Porcupine Dam, Gordon H. Flammer, C. Earl Israelsen

Reports

Introduction: The Engineering Experiment Station at Utah State University was engaged by the Utah Water and Power Board to make a model analysis of the spillway and stilling basin of the Porcupine Dam. This dam will be located on the East Fork of Litle Bear River, just east of Avon, Utah. It will be approximately 650 feet long and 160 feet high, composed of zones earth fill with rock rip-rap facing. The spillway will have a reinforced concrete inlet section and the remainder of the chute and stilling basin will be excavated out of the rock and leck unlined. The …

Lower James River Pollution Study, City Point To Chickahominy, August 6 - September 6, 1951 : A Preliminary Report Of Findings, Conclusions And Recommendations, William H. Massman, Ernest C. Ladd

Reports

Hopewell,m Virginia.is ·a highly industrialized city, the Celanese Corporation of .America, the Continental Can Company, the Hercules Powder Company and the Solvay Process: Division of· Allied Chemical and Dye Corporation having plants there. All of these plants have industrial and human wastes, the combined amount of which is great from. the standpoint of both volume and strength. In addition, there. are human wastes from the City cf Hopewell and its suburbs in Prince George County and from Camp Lee. All of those wastes, sewage and industrial are discharged into the James River, Bailey Creek and into other tributaries of the …

Hydrographic Data From The Atlantic Plankton Cruises Of The R/V Pathfinder, December 1959 - December 1960, Edwin B. Joseph, William H. Massmann, John J. Norcross

Reports

The data included in this report have resulted from a series of monthly offshore cruises conducted by the Ichthyology Research Section. The cruises were made to obtain information on the distribution and abundance of pelagic eggs and larvae of fishes. Since the biological results will be reported in a series of separate papers (Joseph, Massmann and Norcross, 1961), it was felt that the raw hydrographic data shpuld be made available in a single source.

The area covered is approximately 2500 square nautical miles of the neritic zone within the 20-fathom contour. The shore line encompasses the mouth of Chesapeake Bay …
