Terraces divide slopes so that surface runoff is intercepted and carried to a protective outlet. Terraces decrease erosion by shortening slope length, slowing runoff velocity, and trapping sediments. Runoff water concentrates in waterways that when bare or unstable are extremely erodible.

What is sloping terraced farmland?

Under sloping or retention terraced farmlands, only riser dikes are built and no land levelling is made. The land surface will be flattened gradually by deep ploughing over the years. The spacing between riser dikes varies with the natural slope.

What is a terraced yard?

A practical way to convert the hillside into usable garden plots is through terracing. Resembling a wide staircase, terraces allow you to have several level gardening beds on the hill so you gain more overall yard square footage. Take all the factors into consideration when planning your terraced yard.
