Analysis of Hollinshed Watershed Using GIS Software

摘要

The objective of this study is to apply GIS and storm water modeling software to develop an accurate hydrologic model of the Hollinshed watershed. Use of GIS will allow the user to quickly change the land use of specific areas within in the watershed to determine the hydrologic effects throughout the watershed using the storm water model. Specific objectives were to: (1) develop a GIS database for the Hollinshed watershed; (2) Develop an appropriate link/ node diagram and corresponding input file for the storm water model Drain:Hydro(registered); and (3) Study impact caused by current and future development on the storm water runoff in the watershed.
