Long Term Performance of Water Quality Ponds
A report developed under EPA's Nationwide Urban Runoff Program (NURP) describes an analysis methodology and presents graphs and example computations to guide planning level...

Rainfall Analysis for Efficient Detention Ponds
Intensity-duration-frequency analysis of rainfall data is traditionally used for the selection of design storm required to size, storage capacity in detention/retention ponds without consideration...

Monitoring and Design of Stormwater Control Basins
The City of Austin, Texas, has played a pioneering role in the control of urban nonpoint source pollution by enacting watershed and stormwater ordinances, overseeing detailed monitoring...

Multiple Treatment System for Phosphorus Removal
Detention ponds, wetlands, and infiltration basins have each been shown to reduce constituent loads carried by urban stormwater, including phosphorus. Design recommendations are presented...

Load-Detention Efficiencies in a Dry-Pond Basin
Inflow and outflow to a dry-pond detention basin in Topeka, Kansas, were monitored for 19 storms during a 14-month period. Samples of runoff were collected automatically at two inflow...

Simulated Water-Quality Changes in Detention Basins
A study has begun to simulate movement of stormflow through detention basins at four locations in the Irondequoit Creek watershed and determine the effect on peak flow and water quality....

Water Quality Study on Urban Wet Detention
This paper summarizes results of a monitoring program conducted on three urban wet detention ponds located within the Piedmont region of North Carolina, in the city of Charlotte. Data...

Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...

Systems for Artificial Recharge of Ground Water
Design and management of infiltration systems should be adapted to local conditions of water quality, climate, soil, hydrogeology, and environmental constraints. Aspects to be considered...

Hydraulic Effect of Turbid Water Infiltration Through a Shallow Basin
A 225 m² test basin was operated from September 1986 through October, 1987, to determine the hydraulic effects of turbid water application. Initial...

Bacterial Fingerprinting to Trace Source of Coliform Bacteria During Artificial Recharge
This report describes the use of a bacterial 'fingerprint' technique to determine if treated effluent from infiltration beds was the source of coliform bacteria...

Quality Changes of River Rhine and Meuse Water Upon Basin Recharge in the Netherlands' Coastal Dunes: 30 Years of Experience
A wide spectrum of quality changes of river Rhine and Meuse water is presented, on a global scale after pre-treatment, dune infiltration and post-treatment. Attention is focussed on the...

Ground Water Recharge Through Excavated Basins
Excavated basins were used to bypass slowly permeable soils in the Southern High Plains and artificially recharge the Ogallala aquifer. Recharge rates with turbid playa water were as rapid...

Artificial Recharge with Imported and Reclaimed Waters in Central and West Coast Basins of Los Angeles County
Since 1952 over 4,000,000 acre-feet of imported water and reclaimed waste water have been purchased to recharge the ground waters of the Central and West Coast Basins of Los Angeles County....

Infiltration Maintenance in Recharge Facilities of Orange County Water District
The Orange County Water District manages the Orange County ground water basin in western Orange County. In the first 25 years of operation, the District made exclusive use of the Santa...

Ground Water Basin Management and Artificial Recharge
In Coachella Valley, California, where rainfall averages only 3 inches annually, approximately 80,000 acres of crop land and 65 golf courses provide winter recreation and winter fruits...

Ground Water Recharge in Ganga Basin
Ganga Basin is the repository of ground water in the Indian sub continent. The area is subject to frequent drought. Tubewell development both in the state and private sectors has been...

Experimental Studies of Artificial Recharge of Ground Water in Yamagata City, Japan
Experimental studies on artificial recharge of ground water were carried out for three years in Yamagata City, Japan. Two types of installation, pit and basin method were used for recharge....

Artificial Recharge of the Heretaunga Plains Aquifer Hawke's Bay, New Zealand
The Heretaunga Plains groundwater system in the Hawke's Bay region of New Zealand, is naturally recharged from the nearby Ngaruroro River at the approximate rate of 5.5m³/sec....

Optimal Process of the Development of the Residential Area on the Coastal Zone
The concentration of population and assets through various types of development in the coastal zone in Japan is progressing rapidly at present. The conditions of the sea environment are...
