Kansas StreamStats

The primary purpose of the Kansas StreamStats application is to incorporate statewide regression equations for estimating rural peak flows with annual exceedance probabilities of 50, 20, 10, 4, 2, 1, 0.5 and 0.2 percent. These peak flows have recurrence intervals of 2, 5, 10, 25, 50, 100, 200 and 500 years, respectively. The report below documents the available regression equations in Kansas, the methods used to develop the equations, the basin characteristics used in the equations, and the errors associated with the estimates obtained from the equations. Users should familiarize themselves with the report before using StreamStats to obtain estimates of flows for ungaged sites in drainage basins.
