Storm Water Program
Hydromodification
State and Regional Water Board staff (aka The Mod Squad) will discuss and strategize on ways to better understand, analyze and control the impacts to California's waters from hydromodification.
Hydromodification is defined as: alteration of the hydrologic characteristics of coastal and noncoastal waters, which in turn could cause degradation of water resources. In the case of a stream channel, this is the process whereby a stream bank is eroded by flowing water. This typically results in the suspension of sediments in the water course.
