Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...

Stream Instability in Loess Base Channels
The incision of bess base stream channels is a common and destructive response to alterations within a watershed in the midwest. Monitoring and evaluating procedures are being performed...

Restoration of Abandoned Meanders on the Middle Fork Forked Deer River, Tennessee
The Middle Fork Forked Deer River in western Tennessee historically had a sinuous course within a wide floodplain. In the early 1900's, local interests dug large straight...

Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...

Impacts of Climate Change in the Missouri River Basin
The Soil and Water Assessment Tool (SWAT) is being used as a base model to simulate the Missouri River basin for prediction of the impacts of climate change on water resources in the region....

Flood Damage Estimates Using GIS Spatial Analysis
The catastrophic flooding in the midwest during the Summer of 1993 and in California in the Spring of 1995 resulted in flood damage estimates in the hundreds of millions to billions of...

Water Balance of the Niger Basin
A map-based method is used to construct a monthly water balance model of the 2.3 million km Niger River basin in West Africa. The watersheds and stream network within the basin are derived...

Model for Water Quality in Periphery of Distribution Systems
A model is presented for water travel time and chlorine concentration in periphery dead ends of the water distribution system. The model is developed under the premise that residential...

The Management Improvement Program: An Irrigation District's Perspective of the Demonstration Program
In November 1990, the Maricopa-Stanfield Irrigation and Drainage District agreed to participate in the first application of the Management Improvement Program (MIP) for irrigated agriculture....

The Cost of Highway Bridge Scour in the State of Minnesota
Different states are faced with different conditions with respect to geology, topography, climate, native vegetation types, bridge ownership, and bridges management systems, which in turn...

Channel Restoration Project along Toby Creek
Creek banks within Mecklenburg County, NC, are eroding, producing excessive quantities of sediment in the creek and causing bank instability. Seeking innovative approaches to these problems,...

Reclaiming Denver's Central South Platte River
The South Platte River reaches from the 14,000 foot peaks west of Denver more than 300 miles east to its confluence with the North Platte River at North Platte, Nebraska. As the South...

South Platte River Restoration through Maintenance
This paper describes the use of restorative maintenance activities by the Urban Drainage and Flood Control District to clean up, stabilize and restore river banks and grade along the South...

Simulating DBP Precursor Transport in Sacramento Delta
Fate and movement of disinfection by-product organic precursors in California's Sacramento-San Joaquin Delta was simulated for a 365-thy period with a hydrodynamics and transport...

Interruptible Option Contracts
Interruptible option contracts have been proposed and studied in numerous parts of the Western United States as an alternative supply option for water systems in an economically higher...

Increasing Computational Accuracy of Radial Gate Flows
Radial (Tainter) gates are the most widely used flow control structure on large, open channel conveyance systems. In contrast, the hydraulic forces are complicated and this type of gate...

Developing a Rating Table for the Central Diversion Dam Radial Gates
The Central Nebraska Public Power and Irrigation District uses radial gates for flow control throughout its system. The rating tables for five radial gates on a diversion dam are in error,...

Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...

Waste of Water Is Costly. Why Not Use an Accurate Flow Monitoring System?
Water becomes more and more a precious good. Therefore the exact measurement of flow of water, the management of water and process control in connection with water will become more and...

County-Wide Drainage Study Using GIS
A county-wide drainage study was conducted for the County of San Joaquin, California, Department of Public Works, for the determination of storm runoff quantities for the planning of flood...
