CX(s) Applied: B1.3
Date: 09/08/2011
Location(s): New York
Offices(s): West Valley Demonstration Project

The purpose of the proposed work is to mitigate three knickpoints (step changes in the stream channel bed surface topography, possibly indicating water erosion) located between the north plateau and south plateau of the West Valley Demonstration Project at the Western New York Nuclear Service Center along the Erdman Brook corridor. This section of Erdman Brook is located adjacent to two radioactive waste disposal areas and two radioactive water treatment lagoons.
