Sediment Retention and Erosion Structure

SEDIMENT RETENTION OR EROSION STRUCTURE…

A short, earthen dam across a drainage-way where a terrace is impractical; usually part of a terrace system.

How it works:

An embankment is built across a depressional area of concentrated water runoff to act similar to a terrace. It traps sediment and water running off farmland above the structure, preventing it from reaching farmland below.

How it helps:

Basins improve water quality by trapping sediment on uplands and preventing it from
reaching water bodies.
Structures reduce gully erosion by controlling water flow within a drainage area.
Grass cover may provide habitat for wildlife.
