Impact of Digital Elevation Model Grid Size on Extracted Drainage Parameters
The dependence of extracted drainage network properties on the spatial resolution of DEMs is investigated for a study basin. A series of raster DEMs of increasing cell size is generated...
Design and Analysis of an Irrigation Pond Using Urban Stormwater Runoff
Stormwater held in detention ponds can be reused for irrigation. A simulation of a mass balance on pond storage volume using rainfall and evaporation data for selected areas is presented...
Combined Sewer Overflow Abatement by Means of Detention Basins and Stormwater Infiltration
The conventional approach to abate the pollution loads from combined sewer overflows (CSO's) is to include detention basins. The same reduction in CSO loads may be obtained by infiltrating/percolating...
Performance of Stormwater Ponds and Wetland Systems
The use of stormwater pond and wetland systems to improve the quality of urban stormwater runoff has become an increasingly important strategy to protect streams in developing areas. This...
Predicting Runoff from Rainfall Using Neural Networks
This paper shows the modeling technique, neural nets, to be successful in predicting the hydrograph of a storm from the hyetographs of storms on the same basin. A root mean square error...
Reservoir Regulation and Real-Time Models for Trinity River Flood Prevention and Control
After unprecedented flooding from the Spring of 1989 through 1991 in the Trinity River basin, the Texas legislature allocated funds for flood related studies in Senate Bill 1543 (1991)....
Petrochemical Facility Stormwater Management?A Case Study
As an integral part of a study to develop a combined wastewater treatment system for petrochemical facilities, comprehensive hydrological studies were performed prior to the detailed design...
Sacramento Drainage Manual?Hydrologic Procedures
For a period of over two years, HDR Engineering, Inc. (HDR) and HYDMET have been working with the City and County of Sacramento to develop a Drainage Manual. This Manual contains seven...
Sacramento Hydrologic Procedures Interim Adoption
In November 1989, the County and City of Sacramento jointly undertook the development of a manual for the design of drainage and flood control facilities in the region. Significant technical...
Stochastic Modelling of Mean Monthly Runoffs for Coruh Basin, Turkey
Stochastic models of monthly runoffs for Coruh basin, Turkey are presented. Coruh basin is located on the northeast part of Anatolia near Black Sea. Three gauging stations which have about...
Orange River?System Analysis
The Orange River drains the largest basin in Africa south of the Zambezi with a total catchment area of approximately 1 million km2. Due to the increasing...
Future Urbanization Effects on Occoquan Dam PMF
The Fairfax County Water Authority's Occoquan dam, in northern Virginia, are being anchored at a cost of about $2 million. The reason is to increase stability due to an increased PMF estimate...
Flow Augmentation in the Fenholloway River Basin
Methods to enhance water quality were examined in a north Florida river basin containing industrial wastewater effluent from a paper pulp mill. Streamflow augmentation was determined to...
The Covington Master Drainage Plan
Located in the southeastern portion of King County, Washington, the 1,240-acre Covington area had been identified in 1985 as an 'urban activity center,' a place designated for regional...
GIS Utilization for Analysis of District Drainage Water Recycling
An ARC-INFO GIS system was used to identify physical drainage facilities in a 32,000 ha area of the San Joaquin Valley of California. Once the drainage facilities and linkages were established,...
Modeling the Distinction Between Regional Flow and Flow to Drains
Previous research at the Newlands Agricultural Research Center, in Fallon, Nevada, suggests that the quality of the water flowing to the 15 subsurface drain laterals in related to the...
Water Distribution Plan Utah Lake/Jordan River Basin
The Utah Lake/Jordan River basin is comprised of several river systems that are hydrologically related but, for the most part, have been managed and operated separately. To further complicate...
Distribution of Stable Isotopes in Ground Water in the Rialto-Colton Basin, California
Since 1982, imported water originating in the Sierra Nevada has been used to recharge the Rialto-Colton ground-water basin, about 100 km east of Los Angeles. Stable isotopes of oxygen...
Controlled Versus Conventional Drainage Effects on Water Quality
Fertilized cropland is a nonpoint source of nitrogen and phosphorus which can contribute to nutrient enrichment problems prevalent in many surface water ecosystems. Research has shown...
Effect of Agricultural Drainage on Water Quality in the Great Lakes and Cornbelt States
The soils and the climate of the Great Lakes and Cornbelt states dictate that drainage is required to carry out economically viable farming activities. When drained, the soils are very...
