A Conceptual Basis for Developing Model State Water Codes
The crafting of model state water codes must proceed out of the recognition that there are two prevailing philosophies under which resources are allocated. These contrasting systems both...

Drainage Design Criteria: Too Restricted? Too Broad? Too Outdated?
Should drainage design policies be more flexible, leaving the field more open to engineering judgment? Are some policies too loose or broad? Should design criteria more closely reflect...

MORE-A Multi-Objective Ranking Environment for Risk Assessment
This paper explores the development of a computerized decision support system for ranking risks due to environmental concerns. The paper begins with a brief history a comparative risk...

Applying Benefits-to-Costs Analysis for Stormwater Improvement Projects
Benefit-to-cost analyses provide a measure of evaluation for the justification, selection, and prioritization of stormwater improvement projects. Facing increased competition for tax dollars...
