The purpose of this page is to define watercourse, a commonly used term in floodplain management. To explore other common floodplain management terms access the NFIP Policy Index.
Definition/Description:
A watercourse means only the channel and banks of an identifiable watercourse, and not the adjoining floodplain areas. The flood carrying capacity of a watercourse refers to the flood carrying capacity of the channel (except in the case of alluvial fans, where a channel is not typically defined).
