Final Report Anclote Commercial Plankton Monitoring Program, E. P. Wilkens, W. R. Weiss, J. D. Horne

Reports

Commercial plankton were monitored in the vicinity of Florida Power Corporation's Ancolote power plant from January through December, 1976 in order to assess the entrainment potential for ichthyoplankton and planktonic stages of commercially important invertebrates and to estimate the annual standing crop of these organisms.

The purpose of this report is to present commercial plankton data collected at anclote from January through December of 1976. Additional data gathered by Florida Power Corporation and the University of South Florida during 1975 is also discussed. Entrainment loss estimates for commercial plankton have been calculated and are discussed in terms of their possible …

Assessment Of Mechanical Damage To Entrained Ichthyoplankton, Vepco Surry Nuclear Power Station, J. V. Merriner, A. D. Estes

Reports

Thermal plume ichthyopla~kton sampling during November and December 1976 was cancelled since Units 1 and 2 of VEPCO Surry Nuclear Power Station were non-operational due to refueling. In lieu of the thermal plume ichthyoplankton entrainment program, a sampling program to estimate mortality from mechanical damage was initiated.

Four sampling sites were selected for determination of quantity and condition of organisms entering and leaving the plant. Sites were selected at points preceding and following critical areas where the likelihood of damage was greatest. Net .sets were made using a 0.5 meter paired net apparatus. All sets were at bottom strata to …

Environmental Effects Of James River Sewage Treatment Plant Outfall Construction, Dexter S. Haven, Paul C. Kendall, Robert J. Diaz, Donald F. Boesch, Michael E. Bender

Reports

In the spring of 1975 the Institute began a program to determine whether significant environmental changes would occur in the area of the new James River Plant outfall that might be related to its construction and/or initial operation. Parameters measured in the study were benthic animal and oyster populations, coliform levels and chlorine residuals. The primary emphasis of the study centered on the estimation of the impact of the construction activity on shellfish beds in the area. The results of the investigation are presented in three segments, the first dealing with shellfish populations, the second with other benthic animals and …

Oyster Spatfall On Shellstrings In Virginia Rivers: 1976 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of M3rine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur, Shells planted just before the period of maximum set have the best chance of getting a good strike,

A Study Of Feasibility Of State Water User Fees For Financing Water Development, Daniel H. Hoggan, O. W. Asplund, J. C. Anderson, D. G. Houston

Reports

Water user fees imposed by a state on major water uses is a possible new alternative source of state water development funds. A fee, similar to an excise tax, might be charged for the use of the water resource per se, which in a number of states is declared to be the property of the public of the state. States generally have not employed such fees as a source of operating funds for water agencies or of development capital. Only in the area of water based recreation-fishing, coating, camping, etc.—have states extensively employed user fees. The revenues from these fees, …

Seedability Of Winter Orographic Storms In Utah, Geoffrey E. Hill

Reports

The primary objective of this research has been to collect and analyze data from (randomized) seeded and unseeded winter storms over the Wasatch Mountains for the purpose of developing and designing cloud seeding technology. Two field programs were conducted sequentially; the first was done by airborne seeding and the second by seeding from mountaintop generators. Analysis of precipitation estimators based upon radar and/or rawinsonde data and target precipitation show that increased precipitation due to seeding may occur under certain meteorological conditions. Favorable conditions were found when the supercooled water concentration as measured by aircraft icing rates was high. Precipitation in …

Series Intermittent Sand Filtration Of Wastewater Lagoon Effluents, David W. Hill, J. H. Reynolds, D. S. Filip, E. J. Middlebrooks

Reports

Previous researches have found single stage intermittent sand filtration to be a feasible and economic means of upgrading wastewater lagoon effluent to meet future standards. However the major constraint on their use has been the length of the filter runs. Laboratory scale and pilot-scale series intermittent sand filtration of wastewater lagoon effluents has been found to substantially increase the length of filter runs as well as produce a high quality effluent able to meet future standards. Higher loading rates were round to be possible with series intermittent sand filtration. The operation consistently produced an effluent meeting present Utah “Class C” …

Effects Of Soil Heterogeneity On One-Dimensional Infiltration, Charles Courette, Roland W. Jeppson

Reports

A parameter study for heterogeneous infiltration was performed employing a one-dimensional computer program. Soil heterogeneity was defined by linear variations of soil parameters. From the solutions obtained, the instantaneous and accumulative infiltration rates were correlated versus the rate in which the parameters varied in the soil profile. The end result being coaxial graphs from which a relative infiltration rate may be obtained by inputting time and the rates of change of various soil parameters.

Reports

Sizable investments have been made and continue to be made throughout the world to develop irrigation potentials. Recent food shortages have heightened the concern for obtaining greater returns to irrigation through improved water management and use. A knowledge of how plant growth cycles relate to moisture and salinity levels in the root zone is prerequisite to developing practical ways of maintaining optimum conditions for maximum production per unit of water concerned. This research further defines the role of irrigation timing and salinity management on crop production, and proposes practical techniques for predicting the crop response to management measures.
