2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

A waterway is an artficial drainage channel constructed along the steepest slope to receive runoff from cutoff drains and graded structures and drain to the natural waterway safely.

2.2 Detailed description of the Technology

Description:

A vegetative waterway is constructed in areas where stone is not available and in gentle slopes. Paved waterways are suitable in steeper terrains and areas with large amount of stones. The waterway carries excess water to the river, reservoirs or gullies safely with out creating erosion. It is applicable in all areas where excess water is generated when high rains are received which are beyound the intake capacity of soils. The excess water then will have to be disposed sefely to natural outlets. Waterways are established a year or two before cutoff drains and field structures are constructed. Vegetative waterways are formed by digging earth channel across the contour in the direction of flow. After making the channel suitable grass species are planted or are made to establish naturally. Maintenance is very vital in waterways. Breaks in channel or embankments, moving of silt deposited or keeping the grass shorter in order that it does not obstract flow. Vegetative waterways could be stablized by planting short growing grasses, sodding or letting natural growth.
