NetSTORM is CDM's computer program for precipitation data assessment and rapid long-term urban runoff simulation. The software performs: Storage – Treatment – Overflow Runoff Modeling Precipitation intensity – duration – frequency (IDF) analysis Time series aggregation and synthetic disaggregation Data conversion from various US National Weather Service formats to tabular formats Automated SWMM model simplification, gradually varied flow profiles, and more NetSTORM adapts selected algorithms originally included in the U.S. Army Corps of Engineers HEC-STORM program and extends the STORM methodology to simulate systems with multiple control structures. It has been used in CSO, SSO, industrial stormwater, and pump station planning studies worldwide. NetSTORM was used to establish stormwater detention basin design guidelines for the California Stormwater BMP Handbooks. NetSTORM is designed for Windows operating systems, including Vista. It operates in metric or English units. It is available free for download and use. Online Help       Support       IDF Sample       SWMM       DYNSYSTEM       Legal
