Lab 2 - Watershed Delineation and Risk Calculation 11/4/2017 Part 1 - Watershed delineation Introduction The purpose of this lab is to familiarize the user with the process of watershed delineation. This method is multipurpose. Water quality is a large component of watershed analysis. All water in a single shed flows towards one point, if there is a source of pollution higher in the watershed, all downstream locations will be impacted. Similarly, the amount of water in a watershed is a crucial measurement for resource use, partitioning, and planning. In times of high amounts of precipitation, watershed analysis can also serve a predictive function in flood and overflow potential. While this lab skims the surface of the capabilities of watershed delineation, a fundamental understanding of function and development are established. Methods The process of watershed delineation is complex and for the purposes of this lab, broken down into three steps. The three steps used a
