Applying a Simple GIS to PMP Analysis in a Microcomputer Environmentby Mark W. Killgore, Ebasco Services Inc, United States,
Abstract: The analysis of probable maximum floods (PMF) in the Northwestern United States requires the inclusion of a snowmelt component combined with probable maximum precipitation. Traditionally the approach has been to planimeter the area by bandwidth for each subbasin included in the model to develop a curve of area below a certain elevation versus elevation. It was decided to seek an alternative approach for the evaluation of the 7,100 square mile Flathead River Basin in Western Montana. Three alternatives were considered. Two were on a small scale basis to determine the most economic approach to develop the topographic data base. These are discussed in the paper, along with study results.
