Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...

Are Erosion Control Programs Reducing Sedimentation?
In the Midwest, the USEPA National Watershed Monitoring Program is determining the effectiveness of land management strategies to improve water quality and biological diversity. The illinois...

Controlling the Impacts of Development on Storm Water Quality through Proper Site Planning and Design
Land development and construction activities can significantly alter drainage patterns, increase runoff peak flow and volume, and contribute pollutants to storm water runoff. Federal and...

Assessing Water Quality Impacts of Stormwater Runoff
Current water quality monitoring of non-point source runoff typically involves periodically measuring a laundry list of chemicals in the runoff waters. This approach, while satisfying...

Increasing Computational Accuracy of Radial Gate Flows
Radial (Tainter) gates are the most widely used flow control structure on large, open channel conveyance systems. In contrast, the hydraulic forces are complicated and this type of gate...

Developing a Rating Table for the Central Diversion Dam Radial Gates
The Central Nebraska Public Power and Irrigation District uses radial gates for flow control throughout its system. The rating tables for five radial gates on a diversion dam are in error,...

Discharge Characteristics of Overshot Gates
Overshot gates are becoming increasingly popular for controlling water levels in open channels because of the ability of the gates to handle flow surges with limited depth changes. While...

Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...

BASINS—A GIS-linked Watershed Analysis and Modeling Tool
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) is a GIS based tool developed by EPA's Office of Water to help States target and evaluate water...

Los Angeles County Department of Public Works Storm Water Quality Assessments, Los Angeles, California
This study included a general assessment of the surface water quality conditions within the Los Angeles County area by examination of the surface water quality data collected by LACDPW...

An Integrated Coastal Management Plan for Mamala Bay
Integrated coastal management plan (1CM), articulated in the 1993 National Research Council study Managing Wastewater in Coastal Urban Areas (NRC,1993) is a new framework for coastal environmental...

Salinity Management for the Upper Gila River
Over development and over allocation of the limited water supply of the S afford valley in eastern Arizona has resulted in serious depletion of water for irrigation in the San Carlos Apache...

Evaluation of System Constant Volume Control
System constant volume control (SCVC) has been developed for optimal control of canal systems. The objective of system constant volume control is to maintain a reference storage (or target...
