What is SEDCAD?

SEDCAD stands for "Sediment, Erosion, Discharge by Computer Aided Design". The current version, SEDCAD4 for Windows, was developed specifically for the design and evaluation of alternative surface water, erosion and sediment control systems with a focus on earth-disturbing activities.

It is a comprehensive program that includes hydrology, hydraulics, and design and evaluation of the effectiveness of both individual and an integrated system of surface water, erosion and sediment control measures with respect to sediment trap efficiency and prediction of effluent sediment concentration.

SEDCAD4 is being used to design and evaluate surface water, erosion and sediment control systems for surface mining (coal and hard rock), residential subdivisions, commercial properties, landfills (municipal, hazardous and low level nuclear), and linear developments such as highways and utility lines.
