Daily Water Budget Model for Water Resources Management
A daily water budget model has been developed and tested for the Clinch and Powell watersheds located in SW Virginia and NE Tennessee. The model integrates available data and simulates...

Stormwater Management in Virginia
In the 1986 budget bill, the Virginia General Assembly directed the Virginia Department of Conservation and Natural Resources, Division of Soil and Water Conservation, to conduct a review...

CLNET?A Computer Model for Tracking Movement, Decay, and Concentrations Throughout Water Distribution Systems
This paper describes a computer program package for modeling the spread and subsequent decay of chlorine for modeling as water travels throughout a water distribution system. This total...

Issues in Regional Water Resources Planning and Management: A Great Lakes Case Study
This paper focuses on the obstacles and opportunities inherent in regional resource management efforts, with the Great Lakes Basin serving as a case study. The following areas are addressed:...

Pinpointing Nonpoint Pollution
The Tennessee Valley Authority is using aerial photography to locate nonpoint sources of water pollution. These cause most of the water quality problems in the region. Failing septic tanks...

Distribution System: Cost of Repair and Replacement
The Safe Drinking Water Act of 1974 mandates that EPA be concerned with the supply of potable water to the consumer. Although most emphasis has been placed on water quality as it leves...

Water Main Cleaning and Lining?A Utility Perspective
The Chester Water Authority is a regional water supply system located in Southeastern Pennsylvania serving a population of over 140,000 people in two countries and a large industrial complex...

Megaproject Management Tool
Program management oversight is an administration innovation in the water and wastewater treatment field. The method is increasingly being used when a public entity takes on a project...

Current Issues in Asbestos Removal
Asbestos is responsible for more worker deaths than any other substance used in the construction industry. This fact has prompted major regulatory changes during the past fifteen years....

Geotechnical Aspects of Karst Terrains
Exploration, Foundation Design and Performance, and Remedial Measures
The presence of solution cavities in karst terrains poses some unique problems in site exploration, design of foundations, and in remediation of problems with existing structures. Case...

Nebraska's Special Protection Area Program
The designation of a Special Protection Area (SPA) under the program allows the state and local natural resources districts to move from the voluntary to the regulatory arena in addressing...

Characterizing Groundwater Protection Zones
A method is presented for using geoelectrical methods along with a supporting systems methodology to define aquifer and/or well head protection zones. The systems methodology utilizes...

Variability of Copper in the International Reach of the Similkameen River, British Columbia
All total copper concentrations measured in soft water during spring freshets were above the Canadian Water Quality Guidelines. Approximately 57% of all 108 observations over the three-year...

Sprinkler and Subirrigation Research Park for Multiple Cropping Research
A research park has been developed to enable scientists to evaluate sprinkler and subsurface irrigation management strategies for multiple cropping rotations. Various sprinkler irrigation...

Irrigation and Nitrogen Management Impacts on Ground-Water Quality
The effect of irrigation management and nitrogen management on ground-water quality has been evaluated for four years on a sandy loam Coastal Plain soil. Nitrogen sidedressing and fertigation...

Modeling Irrigation and Nitrogen Management
Irrigation increases the potential for nitrate accumulation in the groundwater in two ways. It increases the water content in the root zone creating a greater potential for leaching. Two...

Achieving Accurate Irrigation Water Measurements with Propeller Meters
Propeller meters are now being used extensively to help quantify and manage the huge but poorly distributed water supplies available to irrigated agriculture in the western states. Careful...

Selenium in the Kendrick Reclamation Project, Wyoming
Elevated concentrations of selenium in water, bottom sediment, and biota were noted during a reconnaissance investigation of the Kendrick Reclamation Project in central Wyoming. Dissolved-selenium...

Geohydrologic Aspects of Water-Quality Problems of the San Joaquin Valley, California
Salinity and selenium concentrations in shallow ground water of the western San Joaquin Valley, California, are related to the geomorphology and hydrology of the alluvial fans. High salinity...
