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...
Using A Risk-Based Relative Position Analysis to Initiate Water Conservation Measures
When water utilities operate with annual demands close to safe yield, they must be prepared to invoke water conservation measures during droughts to assure adequate supply. Determining...
Comparison of Biological and Chemical/Physical Iron Removal
The report compares the efficiency of chemical/physical and biological iron removal processes during the entire filter cycle. The results of the first three pilot studies performed in...
A 2D numerical simulation of the Po river delta flow
A numerical simulation of the steady flow in the proximity of the delta of the Po river has been carried out. We consider the 2D quasi-hydrostatic model, approximating non conservation...
Scada System Requirements for Optimum Pumping
In order to minimize the cost of electric energy for pumping water through its distribution system, a computer program was developed to schedule the operation at eight pumping stations...
Probable Maximum Flood Estimation for New and Existing Dams
Although various attempts have been made to streamline the procedures to determine PMF hydrographs for the design of new and rehabilitation of existing dams, there still remains a great...
A Physically-Based Model of Channel Widening
The application of many existing models of river channel morphology is limited by their inability to account for bank erosion and changing channel width through time. This paper outlines...
Sediment Modeling in the Rio Grande Conveyance Channel
The Rio Grande Conveyance Channel and the Rio Grande Floodway convey water from the San Acacia diversion dam to Elephant Butte Reservoir. The Conveyance Channel was built in early 1950's...

Effects of Core Sealing Methods on the Preservation of Pore Water
Five general core sealing methods (using Protecore, Lexan, wax, Protecore with wax, and Protecore with Lexan) were studied over a two year period to determine their moisture retention...
Diffusion of Sorbing and Non-Sorbing Radionuclides
Diffusion is considered one of the most important retardation mechanisms in fractured media. The diffusion experiments conducted involved solid tuff and groundwater from Yucca Mountain....
Water Management Plan for Lake Okeechobee
Lake Okeechobee is a large, natural freshwater lake in Southern Florida with a drainage area of about 5,650 square miles. The Corps of Engineers operates and maintains project works on...
Partnering in Water Resources Planning in Florida
This paper discusses successful partnering efforts by the Corps of Engineers in water resources development in Florida. The partnering involves the Corps, local project sponsors and other...
Use of Flood Control Features for Environmental Mitigation
The US Army Engineer District, Vicksburg (CELMK), plans to construct up to 167 water control structures, 52 confined disposal facilities, and 47 barrow pits as part of a major flood control...
An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...
Development of a Raw Water Master Plan Model to Assist Long Range Drought and Water Conservation Planning for the City of Louisville, Colorado
The City of Louisville, a municipal corporation charged with meeting the water demands of almost 5,000 water accounts and faced with a diminishing supply of available senior water rights...
Water Supply Systems Planning with Water Transfers
This study examines the recent use of water transfers in California, particularly during the current drought. The emphasis is on how planners and operators of federal, state, and local...
Upper Guadalupe River Authority, Texas?Innovative Solution to Long-Term Water Needs
Through conjunctive use of groundwater and surface water, the Upper Guadalupe River Authority (UGRA) has designed a water supply system for the City of Kerrville, Texas that saves 80 percent...
Water Use Pattern of Residential and Commercial Customers
The availability of the Automatic Meter Reading (AMR) devices make it possible to read a large number of meters in a short period of time. Through the use of AMR, we monitored weekly water...
Low Flush Plumbing Fixtures and Wastewater Systems
The significance of low flush plumbing fixtures on the wastewater collection and treatment system serving a small community has been determined. Among the concerns studied were: functional...
