Project on Contaminations-Radiation-Ecosystems-Health in Russia
We would like to discuss with you a project that we are currently developing, doing research upon and completing. In our report we represent the the following: - a few experimental data...
Fresno/Clovis Water Management Plan
The Fresno/Clovis Metropolitan Area (FCMA) in California has historically relied solely on untreated, undisinfected groundwater as a source of potable water to serve 500,000 people. Contamination...
Public Process in Fresno/Clovis Water Supply Plan
Groundwater is the principal reservoir for the Fresno/Clovis Metropolitan Area (FCMA) of Central California. However, significant portions of the aquifer are threatened by pesticides and...
Juanita Creek Channel Restoration?King County, Washington
Juanita Creek, a small basin near Seattle that contains anadromous fish, was experiencing degradation due to urbanization. A detention pond and channel restoration improvements were constructed...
An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...
Water Temperature Issues in the 90's and Beyond
Temperature impacts are among the most common and most expensive environmental issues requiring mitigation at water projects. Several emerging environmental and regulatory concerns and...
Sacramento and Trinity River Systems: A Demonstration of River Temperature Management for the 90's
Drought in Northern California resulted in the potential that summer and early fall, 1992, Sacramento and Trinity River temperatures would exceed critical levels for sustaining salmon...
Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...
Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...
Pollutant Removal Efficiency of Detention Basins
A simple method is presented for quick estimates of pollutant removal efficiency of detention basins under dynamic conditions. The method is based on the generalized solutions to the reservoir...
Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...
GIS Reconstruction of Exposure to Water Supply Contaminants
Groundwater pollution resulting from improper waste handling practices in the aerospace industry contaminated the water supply in Tucson, Arizona. State and federal health officials concluded...
Solute Transport Modeling under Unsteady Flow Regimes: An Application of the Modular Modeling System
Many existing solute transport codes rely on the assumption of steady (i.e. time-invariant) flow. This assumption severely limits such models, as accurate simulations often require realistic...
Application of Computer Support for Water Quality Management
A Computer-Aided Support System for operation of the QUAL2E-UNCAS river water quality model has been developed for the California Regional Water Quality Control Board, North Coastal Region....
CASS for Evaluating Hg Contamination in Clear Lake, CA
Characterization of ecosystem contamination and evaluation of potential mitigation schemes represent two of the most immediate challenges to management of water resources. Heavy metals...
The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...
A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...
Ground Water Management Standards and Protection Tools
Once local goals and objectives for ground-water protection have been defined, wellhead protection areas delineated, sources of contamination inventoried and assessed, management techniques...
Developing an Ecosystem Approach for Restoration of the Bay of Quinte
Author describes the ecosystem approach that has been utilized for the restoration of the Bay of Quinte. Brief description of the study area is presented. Various problems such as bacterial...
Coupled Simulation-Optimization Approach to Wellhead Protection Area Delineation to Minimize Contamination of Public Ground-Water Supplies
A loosely coupled simulation-optimization procedure is used to determine the steady-state pumping rates for individuals wells in a multiple well municipal wellfield that result in the...
