GIS Static Storm Model Development: Literature Review and Progress Report

摘要: Rainfall runoff modeling at a watershed scale requires the definition of storm event and conveying characteristics watershed. This research project focuses on geographic event, that is, spatial distribution precipitation over As size increases, likelihood will cover entire decreases, it becomes necessary to identify which parts are affected by not. Traditionally, estimates have been based records obtained discrete points (i.e., stations), led depth-duration-frequency (DDF) equations or curves. An estimate area covered however, has not included in analysis, customary assume uniformly distributed watershed, regardless its size. Thus far, no model developed map is storm, as well determine this area. Use NEXRAD data, allow development information system (GIS) application relaxes assumption within
