Mexican Border Ground Water Agreement
This paper provides a discussion about the challenges in developing a Mexican Botder Ground Water Agreement for the management of shallow ground waters that connect to the surface water...
Artificial Recharge in the Oakes Test Area
The Oakes Test Area (OTA) was developed to evaluate predicted impacts of developing irrigation in the Garrison Diversion Unit in North Dakota. A limited irrigation water supply has forced...
Cropping Systems on the Delmarva Peninsula to Reduce Ground Water Contamination
A total of twelve cropping systems were simulated with the GLEAMS model for nitrate leaching. A precipitation model was developed using a Markov chain model and a gamma distribution for...
Sanata Ana River Project Environmental Compliance with the National Environmental Policy Act (NEPA)
The National Environmental Policy Act(NEPA) was first enacted in. 1969, and became effective as of January 1, 1970. The law was intended to ensure that balanced decision-making occurs...
Local Sponsorship and Floodplain Management
An outline of Local sponsor for SARP and FEMA floodplain revisions....
Cooperative Approaches in Achieving Additional Water Conservation at Prado Dam
The Orange County Water District (OCWD) has successfully negotiated multi party agreements that provide for the use of Prado Basin for water conservation while ensuring protection of the...
Systems for Forecasting Flows and Their Uncertainty
Discussed are design issues of distributed systems for operational flow forecasting. Results of sensitivity analyses are presented which illustrate forecast flow dependence on model discretization...
Probabilistic Approach for Cancer Risk Assessment
Carcinogenic chemicals have entered ground water systems from surface spills and leaching from subsurface disposal sites. Of particular interest in this study was the contaminant tetrachioroethylene...
Effects of Sewage Effluent Irrigation on Paddy
Paddy, the staple food of South India, occupies about an area of 38 million hectares in India [1, 1987]. Being a semi-aquatic plant, its water requirements are many times more than most...
A Framework for Sanitation and Health Risk Assessment
This paper summarizes some historical, cultural, and operational responses to risk. Zero risk and zero pollution ideas developed as arguably escapist reactions to stresses of economic,...
Small Inocula Can Effect
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...
Risk-Based Planning and Management of Maintenance Dredging
The U.S. Army Corps of Engineers (Corps) Institute for Water Resources (IWR) is developing and applying a risk-based approach to address maintenance dredging cost, reliability, and budgetary...
Portable Flumes with Adjustable Throats
Vertically adjustable flumes for canal flow measurements address several problems in field practice. One involves the perception by some canal water users that flumes and weirs always...
Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...
Hydraulic Design of Subsurface Flow Wetlands
Although Subsurface Flow Wetlands (SFW) have received steadily increasing international attention during the past 10 to 15 years, comprehensive design criteria are not available for some...
Studies on the Erosion of a Compacted Soil
In the management of water there are certain applications in which compacted soil is used (i.e., dams, embankments, levees, spiliways, and channels). Engineers rely primarily on field...
Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Selection of the Form of Calculated Flood Hydrograph in Projecting Water Release Facilities
Traditionally, in evaluating hydraulic structures, river flood runoff hydrographs are determined by maximum flood water volume and discharge, duration of the flood and some other parameters,...
Glacier-Generated Floods and Debris Flows
Sudden release of glacially impounded water causes catastrophic floods, known as outburst floods, and ocasionally spawn debris flows that pose significant hazards in mountainous areas....
