Effect of Best Management Practices on Water Quality in the Appoquinimink Watershed
As part of its 208 program related work, the Water Resources Agency for New Castle County, Delaware, has been involved in an agricultural nonpoint source pollution control program since...

Predicting Quality for Drainage Water Management
In 1982, 405 measurements of the subsurface drainage water quality parameter electrical conductivity (EC) in ds/m were collected. The data were obtained from 15 subsurface drains on 23...

Effect of Subsurface Drainage in the Lower Mississippi Valley on Surface Water Quality
Sediment and nutrient losses were measured from a subsurface drainage-runoff-erosion experiment for the years 1981 to 1984. The experiment, located near Baton Rouge, Louisiana, consisted...

Effect of Agricultural Drainage on Surface Water Quality in Delaware
Parts of Kent and Sussex counties, Delaware, require drainage to have productive agricultural soils. Drainage has been installed on the Delmarva Peninsula since colonial days. Drainage...

Use of Drainage Control to Minimize Potential Detrimental Effects of Improved Drainage Systems
Improved drainage systems are necessary on many soils for sustained agricultural production. However, there are several drainage system designs which can be utilized to satisfy agricultural...

Incorporating Crop Water Use in Drainage Design in Arid Areas
A method of drainage design for use in arid areas was developed by combining procedures proposed by D. B. McWhorter along with plant uptake functions developed by D. W. Grimes and D. W....

Effects of Saline Water Tables on Corn Irrigation
Hydraulic, weighing lysimeters were used for three years to measure the effect of high, saline water tables on irrigation requirement of corn. For each of the years corn was grown with...

An Ecological PlanningApproach to the Development of Local Critical Area Plans
The findings of the Chesapeake Bay Program (CBP), a five year Environmental Protection Agency research effort, depict a complex estuarine ecosystem in decline. Forty separate research...

Analysis of Odors from Polluted Bay Ecosystems
Facility effluents, runoff, sewage and manmade constituents entering bays and streams can provide a source of nutrients which can support the growth of odor producing benthic or planktonic...

Histological Markers of Environmental Effect
This paper evaluates the potential use of histopathology in determining the health of wild fish relative to the quality of the water in which the fish are residents. This paper examines...

Local Government Implementation of Chesapeake Bay Protection
The 1984 session of the Maryland General Assembly concluded with the passage of a legislative package on the Chesapeake Bay. One of the cornerstones of the package is the Critical Areas...

An Open Space Funding Program for Coastal Preservation
The Maryland Program Open Space (POS) Program and funding technique provides a model for the development of a funding program for water quality, tributary, coastal zone, estuarine, and...

PVEM?A Model for Assessing Vessel Air Pollutants
The Port Vessel Emission Model (PVEM) is a computer program which calculates air pollutant emissions resulting from vessel activity in a port for various operations scenarios. These scenarios...

Management Strategies for a Mangrove Estuary
The management plan for Rookery Bay National Estuarine Sanctuary uses three mutually dependent management strategies: developing and implementing a land and water management plan; conducting...

Discharge Zone Classification System for Southern Puget Sound
This paper identifies marine areas where new or expanded discharges are unacceptable based on existing knowledge; e. g. , water quality standards are currently not met, and impairment...

The World's First Hydrorama
The concept of HYDRORAMA exceeds conventional museum-like operations. It includes hotel/motel accommodation, academic courses organized by world-round university sources, permanent expositions...

Coral Reef Modeling: Key Largo Case Study
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...

Off-Site Water Quality or On-Site Productivity
Nonpoint sources of pollution are being recognized as the primary source of water quality degradation in many coastal areas. In those areas where management programs are being implemented,...

Watershed Management in the Eighties
The papers included in this publication discuss state-of-the-art methods and current research on management and present case studies on current projects and practices on applied watershed...

Hydropower
Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...
