From ASDSO Dam Safety Toolbox
Natural Resources Conservation Service, 2015
The stream system of a watershed is divided into reaches, and the watershed into hydrologic units (HU), for the convenience of work as a part of a hydrologic or hydraulic study. This chapter provides some details on the selection of reaches for hydrologic or economic studies, presents alternative means for studies of alluvial fans, and briefly describes a hydrologic unit and its use in a study.
