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...
Parallel SDP for Multi-Reservoir Management
The use of stochastic dynamic programming (SDP) for solving water resources problems has been restricted to problems with low dimension due to the 'curse of dimensionality'. Algorithm...
Water Resources Development in the 1990's: A New Process
The development of water resources to meet future water needs has become more complex nowadays as regulatory agencies attempt to balance the proposed consumptive uses of water with a wide...
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...
Reducing Discharges from San Francisco to the Bay
The City and County of San Francisco (City) is fairly unique in the west because it has a combined sanitary and storm water system. When the current Wastewater Master Plan (WWMP) was completed...
Reliability Analysis of a Multi-Reservoir Water Distribution System

CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...
Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...
Locking Into Success
In 1961, at Wheeler Lock in Alabama, crews with the Tennessee Valley Authority tried to incorporate an existing lock wall into a new cofferdam. A major portion of the land wall slid about...
