Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...
Mixed Solute Interactions in Groundwater Systems
Research results are presented from a study examining the competitive sorption effects of two organic chemicals, para-dichlorobenzene and 2,4-dichlorophenol, to solids from the Cohansey...
Water Resources Systems Planning: Differential Dynamic Programming Models
A Monte Carlo optimization methodology is presented for water resources systems. The planning model define the optimal storage and release policies for the reservoir system. The optimization...
Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
Improving Streamflow and Water Quality Below Dams
Progress by the Tennessee Valley Authority on improving dissolved oxygen (DO) and flow conditions below hydropower projects is discussed. New methods of turbine venting have resulted in...
Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...
Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...
Flood Control, Water Conservation, and Urban Change
Los Angeles County has one of the largest, most complex and effective systems of flood control and water conservation facilities in the United States. It includes 14 major dams, 125 debris...
Heppner's User-Friendly Local Flood Warning System
The Heppner, Oregon, local flood warning system uses state-of-the-art technology with event-initiated data transmission, real-time monitoring, and automatic evaluation and notification....
Financing Water Supply Infrastructure - A Public Works Perspective
The Massachusetts Water Resources Authority was established to ensure that the regional water and wastewater needs were properly addressed, removing the budget process from the legislature...
The United Kingdom Approach to Rehabilitation
Following concern over the condition and performance of its underground assets, the UK Water Industry has developed strategies for cost effective sewer and water main rehabilitation. These...
Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...
A Unified Hydrodynamic-Water Quality Model
To understand the cause-effect relationships controlling water quality in dynamically narrow estuaries, a time dependent branching, laterally averaged (longitudinal and vertical) hydrodynamic...
NID Water Supply and Hydropower Operation Model
A basic requirement of CH2M HILL's Raw Water Master Plan for Nevada Irrigation District (NID) was to determine the dependable water supply available from the District's...
Reservoir System Simulation Through Network Flow Programming
A generalized reservoir system simulation model that makes use of a network flow programming technique has been developed for use in planning and operation studies of multi-purpose water...
Optimal Weekly Operation of a System of Three Multipurpose Reservoirs
Marion, Council Grove, and John Redmond Lakes located in the Upper Neosho-Cottonwood River basin are an integral part of the State Water Marketing Program of Kansas. In addition to water...
Engineering and Policymaking: The Platte River in Nebraska
Substantial conflict exists over proposed water projects in the Platte River Basin of Nebraska. A computer simulation model, representing the engineering and environmental dimensions of...
Community Relations on Hazardous Waste Projects: A Successful Experience
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted at a hazardous waste site, neighboring communities should...
Colorado High Mountain Aquifer Study
This paper describes the potential for formulating water projects in Colorado using the storage capability of high mountain glacial aquifers. Although a terminal moraine provides a natural...
Prediction of Sediment Yield for Southern California Watersheds
