Hydrodiplomacy on Forester Creek
The goal of this paper is to share information regarding political battles confronting the engineer with regards to drainage issues and concerns. Very often drainage boundaries do not...
The Law of the Colorado River: Can It Cope With Severe Sustained Drought?
This paper analyzes the Law of the River from the perspective of its effect on allocation decisions in the event of a long term, severe drought. The analysis is organized in a manner familiar...
A Survey of Stormwater Infiltration Basins in the Puget Sound Region
A survey of 23 infiltration basins in the Puget Sound area was conducted to gain information on the performance of these systems and the degree of compliance with state agency guidelines....
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...
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...
A Salmon Population Model for Evaluating Alternative Flow Regimes
