Alternatives for Managing Shallow Ground Water in Arid Irrigated Areas
The combined operation of a drainage system for subirrigation and drainage is being considered for application in arid areas of the world. This is accomplished by modifying an irrigation...
Liability of Engineers When Wetlands Laws Change
Engineers who perform wetlands delineations or design facilities in wetlands areas are increasingly sued in court when wetlands laws or regulations change. Owners and developers whose...
Rainfall-Runoff Modeling for Watershed Stormwater Management
In the design of watershed stormwater management plans used for land development, the Pennsylvania State Runoff Model (PSRM) presents upstream subbasin flows that contribute to the peak...
Effective Subsurface Retention/Detention Systems
Stringent environmental regulations and increasing land values have made finding an effective way to manage storm water runoff a high priority for consulting engineers and land developers....
Flash Floods and Their Control in the Indian Arid Zone
Flash floods are common hydrologic phenomena in the arid north west India. Drainage basins of high relief, a large percentage of surficial bed rock, sparse vegetation, and shallow soils...
Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things?wise water planning...
Eastern San Joaquin County Groundwater Management
An aquifer system of significant volume is located in Eastern San Joaquin County (ESJC), part of California's Central Valley. The industry in that region is primarily agriculture,...
Development of Islandwide Groundwater Pollution Potential for Taiwan
Using the modified DRASTIC and existing and newly surveyed data, groundwater pollution potentials for all 10 groundwater basins in Taiwan were calculated on 2 km by 2 km grids. This paper...
Modeling of Rattlesnake Creek Watershed Using Swat Model
Watershed scale models are widely used in design and operation of river basin projects and for guiding public decisions. This paper presents modeling details of Rattlesnake Creek watershed...
Changes in Ground Water?Surface Water Interaction in the Santa Ana River Caused by Independent Water Resources Management Activities
For the past 18 years, ground water artificially-stored in the Chino Basin, has been managed as a zero-interest bank account. Recent water resources management studies show that losses...
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...
Wetland Restoration in Southern North Sea Coastal Areas: The Experience of Britain and The Netherlands
Over the past 500 years, extensive reclamation of tidal wetland areas in the lowlands surrounding the Southern North Sea has taken place. In the Netherlands, reclamation has been an essential...
Water Based Land Use Regulations Using GIS Water Budgeting Model
Protection of water quality and supplies in developing watersheds requires maintenance of the natural water budget. Water budgeting model using GIS provides foundation for land use regulatory...
Sustainable Watershed Management in Developing Watersheds
In many parts of the country, land development at the fringe of major metropolitan areas has accelerated and is occurring in historically unprecedented land consuming patterns. This development...
Analyzing Water Balances and Ranking Maryland's Watersheds Related to Growth, Development and Loss of Habitat
One hundred thirty three watersheds comprising the entire state were analyzed for surface and ground water balance. Census population figures (1990) were allocated to the watersheds. Population...
Out of Control?
Once heroes in a popular battle against villainous despoilers of Mother Earth, to a growing chorus of observers environmental groups, EPA and other regulatory agencies have begun to look...
Rest in Peace
Engineers working on a subway connection project in the nation's capital successfully employed chemical grouting techniques--some never tried before--to protect a historically...
Optimal Groundwater Reclamation with Captial Costs
A dynamic optimal control model for groundwater remediation was extended to incorporate treatment facility capital costs. Incorporation of the capital costs had the greatest impact on...
Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...
