Parking Lot Drainage Design: Gainesville, Florida
The construction of a 10-acre (4. 05 ha) parking facility (1,000-car capacity) at the University of Florida during 1984 presented the potential for increasing downstream flooding and for...
Time Variability of Suspended Material Concentrations in Estuaries
The concentration of suspended materials (SMC) within estuarine systems varies in response to a variety of factors. This variability complicates sampling SMC and establishes particular...
Modeling Cohesive Sediment-Pollutant Interaction in Surface Waters
Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating two-dimensional...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
Basin: A Simple Yet Many Faceted Model for Estuarial Impoundments
BASIN is a hydrodynamic and water quality model designed to provide a simplified analysis of flows and constituent concentrations in both tidal and non-tidal water bodies. BASIN is excellent...
Uncertainty in Models for Environmental Management
In recent years, computer models have become increasingly popular as tools to aid the decision-maker in balancing complex, interacting factors in environmental management and pollution...
Evaluation of Water Quality from a Drainage-Subirrigation System in Georgia
Nitrate-N, Ammonium-N and Phosphate-P concentrations were measured from shallow subsurface wells and outlets of a drainage-subirrigation system in the Georgia flatwoods for comparison...
Utilization of Geographic Information Systems Technology in the Assessment of Regional Ground-Water Quality
The U. S. Geological Survey (USGS) in cooperation with the U. S. Environmental Protection Agency Office of Pesticide Programs and several State agencies in Oregon has prepared a digital...
Selenium: It's Not Just in California
The U. S. Department of the Interior has embarked on a series of reconnaissance level investigations throughout the western states to identify and assess potential irrigation-induced water...
Establishing a Monitoring Program for Formulating Water Quality Objectives in a Transboundary Reach
A systematic approach to the establishment of a monitoring program for formulating water quality objectives in the Similkameen River should include the following interactive steps: 1)...
Micro=Lam? LVL: A New Alternative for Timber Bridges
Laminated veneer lumber (LVL) provides a unique opportunity to obtain large structural members from ever-smaller trees. It provides the added benefit of high treatability. This paper explains...
Alternative Formulations for Water Quality Management Models
Various model formulations for water quality management are examined herein, each of which involves a somewhat different approach to the problem of determining optimal treatment levels...
A Water Quality Model for Urbanized Drainage Basins
The Virginia Stormwater (VAST) Model has been developed for use on IBM compatible microcomputers to simulate stormwater runoff and nonpoint source pollution. Hydrologic and nonpoint source...
Water Quality Management Through Project Operation
Harry S. Truman Dam, a multipurpose reservoir project, is located on the Osage River in the headwaters of the Lake of the Ozarks. Construction of this project created the potential to...
Stochastic Stream Flow Analysis for Hydrograph Controlled Waste Release
A risk based procedure for the design of hydrograph controlled release sewage lagoons is derived. The procedure is based on a stochastic analysis of streamflow events above a given threshold...
Reservoir Water Quality Assessment Using in Situ Microcosms
Although there are a number of techniques for determining the limiting nutrient, as will be demonstrated, in-reservoir microcosms permit in situ experiments to be conducted under relatively...
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
An Application of EPA EXTRAN Model to a Flood Management Study in South Florida
In performing the flood management studies, somewhat unique concerns in South Florida are the backwater conditions due to tidal or non-tidal tailwater, flow reversals from project canal...
A Riverflow-Water Quality Control Model
In order to implement how regulated riverflow (control variable) impacts the salinity (output variable) under a tidal dynamic environment, a multiple input control system is developed....
Southeastern Drought of 1986 - Lessons Learned
An interim drought management plan for the Apalachicola-Chattahoochee-Flint (A-C-F) river basin was completed in April, 1985, just in time for testing as the drought developed. Objectives...
