摘要

Land and water amagement activities such as agriculture, soil conservation, and reservoirs for water s upply and flood control, have caused channel degradation in many first and second order ephemeral streams that drain nearly 70b percent of the cohesive environments of the BVlackland Prairie. resurveyed historic cross-sections on Brookeen Creek, a 16 square mile agricultural watershed in Hill COunty, Central texas, revealed a maximum channel incision of 7 feet during a 33 year period (1958-1991). Degradation induced channel bank failures are evident in the form of slumps and block failures.
