Purpose: To trap and collect sediment, reduce on-site erosion, reduce the content of sediment in water, reduce peak rate of flow at downslope locations, reduce flooding, reduce gully erosion, re-form land surface, and improve the potential of areas for farming.
Conditions Where Practice Applies:
a. The topography precludes installing and farming terraces with
reasonable effort.
b. Runoff and sediment from high areas can damage downstream
land or improvements.
c. Water erosion is a problem.
d. Site conditions are suitable for installation.
e. Adequate outlets can be provided.
f. Basins are installed in conjunction with the establishment of a
workable terrace system to stabilize outlets and/or odd areas or
where land treatment practices reduce soil loss to tolerable
limits for the soil involved.
