Summary

This activity consists of a set of problems in which students explore the contributions of water from rainfall and snowmelt over the watershed of the Animas River in southwestern Colorado. Students first compute the area of the watershed (which can be done either graphically or by means of Google Earth), then use climatic data to calculate the relative volumes of water from rainfall and snowmelt. This information is then used to determine streamflow in the Animas River.
