GISHydro2000 is a GIS-based program that automates the analysis of any stream within or draining into the State of Maryland. This document describes the activities conducted over a roughly 2-year period from June 2004 to May 2006 in the continued development and maintenance of this program. Objectives of this work include: 1. Maintain and expand the Maryland spatial database of topography, land use, soils, and precipitation data. 2. Interface GISHydro2000 with the peak flow fixed region equations allowing for calculation of floods of all return frequencies, presentation of error bounds, gage weighting, and performance of calculations across physiographic boundaries. 3. Develop tools for velocity method of time of concentration calculation. 4. Develop and implement a Web-based version of GISHydro. All of these objectives were successfully attained during the project period. |
