  • We are in the process of moving GISHydro2000 to a more secure online environment. As of this date (July 11, 2016) the transition has not been completed. Users are encouraged to follow the steps described in the *** outdated linked document removed ***. You will be notified when the new system is ready to use, and when the current system will be shut down.

GISHydro2000 is a GIS-based software program  for performing hydrologic analysis.  It consists of a database of hydrologic layers and an ArcView™ application with customized modeling tools.  Some Features Include:

  • Complete database of DEM, Land use, and soils data for Maryland drainage area.
  • Watershed and channel delineation.

  • Watershed statistics (drainage area, RCN, tc, more).

  • Peak discharge estimates from USGS regional regression equations (with confidence intervals).

  • Interface to TR-20 for subdivision, parameter calculation, rating tables, and channel routing.

Application of Hydrologic Methods in Maryland, a report prepared by the Hydrology Panel convened by the Maryland State Highway Administration and the Maryland Department of the Environment is available on the Hydrology Panel page.
