Water and Sediment Quality Analyses for the New Boston Wastewater Outfall
This paper describes portions of the farfield hydrodynamic and water quality modeling conducted during preparation of the Boston Harbor Wastewater Conveyance System Supplemental Environmental...
Receiving Water Modeling for CSO Investigations in Boston Harbor
The computer models QUAL2EXP and TEA/ELA were used to model Combined Sewer Overflow (CSO) remediation alternatives in Boston Harbor and its major tributaries. The models were adapted to...
Integrating Hydrodynamic and Water Quality Models for Patuxent Estuary
A two-dimensional mass transport model has been developed to integrate a hydrodynamic model and a water quality model for the Patuxent Estuary, Maryland. In this study, a two-dimensional,...
Boundary Fitted Estuarine Water Quality Model
A two-dimensional, vertically-averaged boundary fitted coordinate pollutant transport model was developed for application to estuarine and coastal sea regions. The governing convective-diffusion...
Advection-Diffusion Calibration of Dissolved Oxygen
Modifications of J.J. Leendertse's water-quality model for improving calculations of dissolved oxygen concentrations in Jamaica Bay, New York, are discussed. Changes to the...
Data-Collection Program for Pamlico River Estuary Model Calibration and Validation
An investigation is being conducted to collect and interpret continuous records relating to the flow characteristics of the Pamlico River Estuary, North Carolina, and to calibrate and...
Water Resources: How Do We Slice the Pie?
New and better ways must be found to: reduce water consumption; preserve environmental values; conserve and protect existing water supplies; use surface and ground water conjunctively;...
Utility of a GIS in Watershed Management?A Case Study
A geographic information system data base was established for a small watershed in Shelby County, Tennessee, for both surface and subsurface water attributes. The surface water portion...
An Interactive Computer Model to Simulate Water Quality of Streamflow from Forested Watersheds in Arizona
To better formulate water resources policies and management strategies, a computer model that simulates concentrations of dissolved chemicals in snowmelt-runoff from forested watersheds...
Validation of Hydrophysical Components of a One-Dimensional Lake Model
A dynamic one-dimensional lake model has been developed in alternative structures, MINLAKE and FRMPND, for water-quality control strategies and lake eutrophication studies. Hydrophysical...
AGNPS: A Tool for Watershed Planning
The AGNPS model was developed to provide a means of assessing water quality impacts from agricultural watersheds. AGNPS simulates sediment and nutrient transport from the headwaters to...
Effects of Mining, Grazing, and Roads on Sediment and Water Chemistry in Birch Creek, Nevada
Assessment of the cumulative effects of mining and other land uses on water quality of Birch Creek showed that mine dumps and roads increased fine sediment deposits in some reaches. Fines...
Watershed Condition and Riparian Health: Linkages
This paper discusses linkages between riparian areas and their contributing watersheds and how using this knowledge will enhance overall watershed management success. The paper presents...
Watershed Planning in Western Pennsylvania?A Case Study
This paper presents and describes the watershed planning activities being pursued in Allegheny County, Pennsylvania. The regulatory, institutional, and technical framework of the planning...
Comprehensive Watershed Management Planning?A Case Study - The Magothy River
As a means of preserving and improving the water resources of Anne Arundel County in the State of Maryland, the County government undertook a comprehensive watershed management program....
Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...
Performance Measures for Irrigation Water Delivery
Performance measures are developed which facilitate analysis of irrigation water delivery systems in light of the objectives of adequacy, efficiency, dependability and equity and of water...
Clean vs. Dirty Water Effects in Irrigation Systems
Seepage losses in irrigation systems may be significantly affected by the suspended solids concentrations of the water. Low-solids clean water increases losses; high-solids dirty water...
Stream Standards for Toxics and Irrigated Agriculture Using New Mexico as a Case Study
New Mexico follows a policy of 'antidegradation' with respect to the existing quality of a stream, but its standards specifically exclude return flows from irrigated...
Management Practice Effects on Water Quality
An array of resource conservation and water quality issues are providing research challenges and opportunities in soil and water, irrigation, and drainage. The key to addressing these...
