Reusable Water Exhange Modeling
Wastewater return flows of raw water which is reusable, i.e., water which is entirely consumable, can be exchanged for a like amount of water upstream in the river basin. Exchanged water...
Development of Fisheries Models for the Missouri River System
This paper describes how the value of fisheries resources under various Missouri River operating alternatives was determined. The four fish communities evaluated were the reservoir cool/warm...
Development of a Wetland/Riparian Resource Model for the Missouri River System
Wetlands and riparian areas are significant resources along the Missouri River, providing important fish and wildlife habitat. These resources required evaluation as part of the review...
Missouri River Least Tern and Piping Plover Model Development
As part of the update of the Missouri River Master Water Control Manual, the U.S. Army Corps of Engineers is evaluating the effects of numerous water management alternatives on endangered...
Development of Environmental Impacts Model for Missouri River System
The Corp of Engineers is reviewing the Missouri River Master Water Control Manual with the goal of determining the best plan for the Missouri River Basin. The Environmental Impacts Model...
A New Approach to Water Education: Children's Water Festivals
A number of Colorado water agencies, school districts, and municipal utilities have combined efforts recently to coordinate a relatively new concept in water education - Children's Water...
Tug Fork Flood Plain Modifications and Wetlands Mitigation
The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment...
Regional Wastewater Reuse in the Nueces Estuary
The results of this study indicate that the firm yield lost to the release requirements of the Texas Water Commission Interim Release Order can be recovered by diverting treated wastewater...
Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...
A Regional Model of Daily Streamflow for the Northeast United States
A regional flow duration curve (FDC) model is under development which relates daily streamflow at 166 unregulated basins in the northeastern U.S. to watershed and climatic characteristics....
Conservation Before and After: The Impacts of Increasing Block Rates on a Fully Metered System
Denver Water's inside residential consumption and revenues changed dramatically during a metering program and a conversion to inclining block rates. We analyze these two changes and make...
Analysis of Missouri River System Operations Alternatives
The Corps of Engineers is conducting a study of alternative water control plans for the exiting Missouri River Mainstem System. Data on the effects of the alternatives on the various project...
Managing the Russian River Aggregate Resources
As a result of analyzing the Russian River and its capacity to provide gravel, and through a sound examination of the geomorphology, hydrology, and groundwater conditions, the Sonoma County...
Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....
A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...
Flood Control vs. Flood Management
For the last 130 years, flood policy in the U.S. has been dominated by the belief that floods can be controlled by structural methods, such as levees, dikes and embankments. These efforts...
Application of the FESWMS-2DH Software to Solve the Navigation Problem at EL-Menya Bridge in Egypt
The purpose of this paper is to introduce the application of a two-dimensional Finite Element Surface Water Modelling System on a navigation problem located along the Nile river in front...
Expert System for Bridge Scour and Stream Stability
Significant engineering judgment is required to ascertain the scour susceptibility of bridges. This judgment is typically acquired through many years of experience. This paper describes...
The Use of SCADA for Real-time Calculation and Monitoring for CT Compliance at the Ralph D. Bollman Water Treatment Plant
The contra Costa Water District (CCWD) of Concord, CA was formed in 1935 under the authority of the State Water Code. CCWD purchases its water supply from the Central Valley Project (CVP),...
Compaction Grouting Stops Settlement of an Operating Water Treatment Plant
In early 1978, about a month into full-time operation, the new filter plant building for the water treatment plant for the City of Glenwood Springs, Colorado, experienced distress due...
