Abstract:

This paper focuses on electromagnetic energy sensors, and describes how they are being used to determine the Probable Maximum Flood (PMF) for a drainage basin in Michigan. Remote sensing is comprised of two major components: data acquisition and data analysis. This paper begins with a look at the fundamentals of remote sensing, followed by a brief description of alternative data sources. This article then describes the aforementioned example of how this technology, along with Geographic Information System (GIS) technology is being applied to a specific hydrologic problem, determining the Probable Maximum Precipitation (PMF).
