Uptake of Contaminants by Overland Flow
A mathematical model is developed for the uptake of contaminants by overland flow. The model is based on the numerical solution of the Navier-Stokes equations coupled with a two-equation...

Lake-Level Declines in Karst Lake During Droughts
Lake-level declines in Brooklyn Lake, a karst lake in north-central Florida, have been investigated. Below average rainfall, vertical leakage to the underlying aquifer system, declining...

Survey of GIS Applications in Surface Water Hydrology
Geographic information systems (GIS), computerized tools for management and manipulation of spatially referenced data, are increasingly being used for engineering analysis and design of...

Runoff Quality Enhancements in Wet Detention Ponds
Wet detention/retention ponds are designed to reduce peak discharge and improve water quality for urban runoff. These ponds remove particulate and dissolved pollutants by sedimentation,...

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...

Anisotropic Effects on Flow from a Recirculation Well
We examined flow in an unconfined aquifer near a recirculation well, which consists of a source and a sink of equal strength, with emphasis on understanding the effects of anisotropy....

A Review of Surface-Groundwater Interaction Models
Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface...

Manning's n From Experiments with Rainfall-Runoff on Portland Cement Concrete Surfaces
Experiments were conducted under artificial rainfall on Portland cement concrete (PCC) surfaces with variable mean texture depths (MTD) and slopes (S). Rain rates were varied up to 3 in/hr...

Global-Scale Assessment of Annual Usable Fresh Water
The quantity of fresh water on earth, although very large, is a limited quantity. A major portion of this water is the polar water that is practically unavailable for human uses. The annually...

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...

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...

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...

Optimizing Conjunctive Water Use in a Dynamic Stream-Aquifer System with US/REMAX
Long-term water management planning models frequently use large time steps and must employ fairly crude assumptions (such as average climatic conditions, etc.). Managing stream aquifer...

Optimizing Steady Point/Non-point Waste and Nutrient Loading to Streams
A simulation/optimization (S/O) model is presented for optimizing pollutant loading to a stream while adequately protecting surface water quality. The S/O model represents surface water...

Estimating Runoff from Precipitation and Temperature
Increasing demands for water and the global climate change resulting from the CO₂ buildup in the atmosphere require an improved evaluation of surface-water...

The Integration and Management of Ground- and Surface-Water Resources for Drought Response in New Castle County, Delaware
This paper reports on a program for the integration and management of ground- and surface-water resources for drought management purposes in the southeastern area of the Commonwealth of...
