A Statistical Comparison Of A Direct Filtration And A Conventional Water Treatment Facility In The Intermountain Region, Susan K. Burns, V. Dean Adams

Reports

Interest in low-cost direct filtration facilities and their effectiveness in treating the potable water sources of the Intermountain Region is increasing as the need for treated water supplies increase. Direct filtration is a water treatment scheme which does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirement, and decreased sludge quantities. Moreover, the direct filtration process may offer large reductions in coagulant dosages and costs.

Currently information comparing a direct filtration system to a conventional water treatment system in the Intermountain area is not readily available. The specific …

Feasibility Of Commercial Fishing Operations In The Mid-Atlantic Continental Slope, Philip W. Cahill, P. Ronald Grulich, James A. Colvocoresses

Reports

The objective of the project was to test the feasibility of conducting commercial trawling operations in the slope waters ( 100 fm-300 fm) adjacent to the traditional fishing areas on the continental shelf in the Mid-Atlantic Bight. This was to be accomplished by developing a fishing strategy that would be structured around existing information on stock abundance, type and location and implementing the fishing strategy by procuring a lease on a commercial fishing vessel that would be suitable for slope trawling. The implementation of fishery operations would be the primary goal of the project and every effort would be made …

Wasteload Allocation Study Tampa Bay, Florida Vol. Iii Model Validation, B. E. Ross, M. A. Ross, P. D. Jerkins

Reports

This volume contains documentation of the calibration and verification (validation) of the hydraulic and water quality models used in the wasteload allocation study (WLA) of Tampa Bay, Florida. The first two volumes in this series contain the derivation and theory behind the mathematical formulation and solution techniques. The study was performed for the Florida Department of Environmental Regulation (FDER) by the University of South Florida (USF). The purpose of the study is to evaluate the effects of alternate discharge loading on the water quality of Tampa Bay.

Wasteload Allocation Study Tampa Bay, Florida Statistical Study, Peter Gaitho

Reports

This statistical study was carried out on the Tampa Bay area in an effort to establish some basic relationships between levels of chlorophyl A and various environmental factors. Several statistical analyses were carried out. It was decided to use original data rather than averages over several months. It was felt that this would give us more reliable results. At the outset, the study centered around the use of data from only three months during the year; namely, February, June and October. It was felt that these months would be representative of the seasonal difference. Later, all months of the year …

Wasteload Allocation Study Tampa Bay, Florida Vol. I Hydraulic Model Documentation, B. E. Ross, M. A. Ross, P. D. Jerkins

Reports

This first volume documents the theoretical development and present state of the University of South Florida's two-dimensional, hydraulic, estuary model. It represents the accumulation of 15 years of research and development at the Civil Engineering Mathematical Modeling Center. It has been designed to be completely compatible with a host of other specialty models including a two-dimensional ecologic model, one-dimensional tributary model, salinity model, thermal model, kinetic energy model, and others. Figure 1.2 is a graphical depiction of the compatibility and functionality of various models used with the 2-D hydraulic model.

Wasteload Allocation Study Tampa Bay, Florida Vol. Ii Water Quality Model Doc., B. E. Ross, M. A. Ross, P. D. Jerkins

Reports

This second volume is a documentation of various transport models used at USF. Included, is a comprehensive documentation of the water quality model used in the WLA of Tampa Bay. Documentation of the particle transport and thermal models has been included in addition to the water quality ecological model because the authors wished to provide a historic listing of the more recent or popular transport models relevant to studies in this area.

Wasteload Allocation Study Tampa Bay, Florida Vol. Iv Nutrient Box Model, B. E. Ross, M. A. Ross, P. D. Jerkins

Reports

This volume describes the "Box Model" of Tampa Bay that was developed as a part of a Wasteload Allocation Study contract between the Florida Department of Environmental Regulation and the College of Engineering at the University of South Florida. The first three volumes document the development of the validated two-dimensional hydraulic and water quality models that were developed for Tampa and Hillsborough Bays. Development of a "Box Model" represents an experiment in simplification of the solution of what has been an increasingly more complicated field of study.

Summary Report On The Calibration Of The Water Quality Models Of The Chesapeake Bay System, H. S. Chen, Paul V. Hyer, Y. Unkulvasapaul, Bruce Neilson

Reports

The intended use of the water quality model was to predict the levels of important water quality parameters. in particular the dissolved oxygen levels and the algal populations. for alternative sets of nutrient loadings. The goals of the present modelling study were to apply appropriate models to the Chesapeake Bay system. to adjust the models so that they accurately simulated conditions in the prototype and to use those models to predict conditions under a number of nutrient loading scenarios. This report provides a summary of the work done to satisfy the first two of those three objectives.

New Concepts For Preliminary Hydropower Design: The Powermax Slope, Binary Turbine Sizing, And Static Regain, Frank W. Haws, Eugene K. Israelsen

Reports

In Utah during the 1960s, the cost of producing electrical energy was as much, or in some cases more, by hydroelectric generation than by plants using steam from coal fired boilers. The relatively high hydropower cost was generally attributed to maintenance and replacement costs associated with plants that had been build in the 1920s. Utah Power & Light Company during the 1960 period decided not to renew power licenses and to abandon many small hdyroplants. Since 1973, rising coal and related fossil fuel costs have caused steam generation costs to accelerate and have made hydroelectric generation relatively more attractive. However, …

A Groundwater Model Of Cache Valley, Utah, Calvin G. Clyde, Roland W. Jeppson, Win-Kai Liu

Reports

This report describes the development, calibration and use of quantitative, predictive management model for the groundwater in the Utah portion of the Cache Valley in northern Utah. The quasi-three-dimensional finite difference computer model was adapted from the U.S. Geological Survey’s Trescott and Larson model and simulates the groundwater levels and flows in the groundwater basin. The variable spacing grid system is 23 nodes x 38 x 2 and represents the complex natural system by a simpler approximation with one unconfined and one confined aquifer and the appropriate boundary and initial conditions. River nodes, spring nodes, and constant head nodes were …
