Description:

This activity prepares you to launch an investigation of the relationship between precipitation and streamflow for a local watershed. It can enrich a study of the water cycle. Following the step-by-step instructions in a case study you will locate, download, format, and finally graph one year of Web-based data for these two variables. The graph highlights the details of this often complex precipitation-streamflow relationship and provides a context for launching a classroom discussion of the balance between surface runoff and infiltration during and after a rain event, soil porosity, soil saturation level, the influence of impervious surfaces in a basin, the impact of slope, wind and air temperature on watershed hydrology, and the influence of high or low vegetation. You should allow at least four 45-minute class sessions if you are planning to use this resource in a school setting.
