SUSTAIN is a decision support system was developed to: - assist
stormwater management professionals in developing implementation
plans for flow and pollution control to protect source waters
and meet water quality goals. - assist watershed and stormwater
practitioners to develop, evaluate, and select optimal BMP
combinations at various watershed scales on the basis of cost
and effectiveness. SUSTAIN is a tool for answering the following
questions: - How effective are BMPs in reducing runoff and
pollutant loadings? - What are the most cost-effective solutions
for meeting water quality and quantity objectives? - Where, what
type of, and how big should BMPs be? SUSTAIN was developed by
Tetra Tech, an environmental engineering and consulting service.
SUSTAIN has seven modules: - Framework Manager - BMP Siting Tool
- Land Module - BMP Module - Conveyance Module - Optimization
Module The modules are integrated under a common ArcGIS
platform, which performs hydrologic and water quality modeling
in watersheds and urb
