HEC Models
HEC-HMS – hydrologic modeling software for converting precipitation into streamflow http://www.hec.usace.army.mil/software/hec-hms/
HEC-GeoHMS – GIS software for setting up HEC-HMS (This is in old ArcView 3). http://www.hec.usace.army.mil/software/hec-geohms/documentation/HEC-GeoHMS11.pdf
A new version of HEC-GeoHMS for ArcGIS versions 8 and 9 (including 9.2) is available: A new version is available on the ESRI ftp site at ftp://ftp.esri.com/HECGeoHMS/ In the Internet Explorer Browser, use File/Login as where login is RiverHydraulics password is river.1114
Tutorial on how to use HEC-HMS –

HEC-RAS – hydraulic modeling software for determining water surface elevation given discharge as input (from HEC-HMS)
