2.1 技术简介

技术定义:

Structure constructed by digging a shallow channel on the upper hill side and putting the excavated soil on the down side to build the embankment

2.2 技术的详细说明

说明:

A structure constructed across the slope along the contour with earth. The embankment is stablized with grasses which is planted during rainy season. Construction is made in groups or by individual farmer, with or without incentives.

Purpose of the Technology: It reduces soil erosion, drain excess runoff during heavy storm which would cause over flow on the land and reduce runoff velocity. Grasses planted on the enbankment for stabilization can solve the animal feed and also soil deposited behind the bund can improve the fertility status of the soil.

Establishment / maintenance activities and inputs: Bunds are continuously repaired during and after heavy storm especially in the first two years after construction. Grasses and tree plant species are planted on the enbankment in order to stablize the structure. Cut and curry and cntroled grazing is common on the embankment.

Natural / human environment: Reduce soil erosion, enhance vegetation growth, improve the beauty of the land scape

Technical knowledge required for field staff / advisors: high

Technical knowledge required for land users: high

Main technical functions: reduction of slope angle

Secondary technical functions: control of concentrated runoff: retain / trap, reduction of slope length, increase in soil fertility

Aligned: -contour
Vegetative material: G : grass

Grass species: Desho (it is local grass)

Slope (which determines the spacing indicated above): 19.00%

If the original slope has changed as a result of the Technology, the slope today is (see figure below): 9.00%

Gradient along the rows / strips: 0.00%

Vertical interval between structures (m): 0.8
Spacing between structures (m): 15
Depth of ditches/pits/dams (m): 0.5
Width of ditches/pits/dams (m): 0.6
Length of ditches/pits/dams (m): 62
Height of bunds/banks/others (m): 0.6
Width of bunds/banks/others (m): 0.5
