StreamStats in Hawaii

StreamStats is implemented for the islands of Kauai, Oahu, Molokai, Maui, and Hawaii, State of Hawaii. The StreamStats for Hawaii application provides peak-flow statistics with annual exceedance probabilities of 50, 20, 10, 4, 2, 1, and 0.2 percent. These peak flows have recurrence intervals of 2-, 5-, 10-, 25-, 50-, 100-, and 500-year floods. The report below presents the equations used to estimate the flow statistics, documents the errors associated with the estimates, and describes the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with this report before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.

A Fact Sheet specific to the Hawaii StreamStats application is also available as a resource:
