2. SLM技术的说明
2.1 技术简介
技术定义:
Dugout pond is a sunken water harvesting structure constructed along the rills in upper catchment for the purpose of storage of runoff and recharge of ground water.
2.2 技术的详细说明
说明:
Dugout pond is a rectangular shape subsurface pond with the excavated material forming an embankment down stream. It is constructed in the upper catchment of the watershed, along the rill/shallow gully. The site for the pond should be where there is a depression. The size may vary from small to large depending on the size of catchment, needs of the farmers, availability of finance, bed rock strata.
Purpose of the Technology: 1- Storage of runoff. 2- Increase in water levels of shallow wells 'odees' through increased percolation. 3- Flood control through series of such structures. 4- Low cost, low risk alternative for poor community. 5- Benefits to community living in upper catchment.
Establishment / maintenance activities and inputs: 1- Site selection with community. 2- Design and preparation of estimate by the project staff. 3- Descussion with VWDC and community, identification of users, descussion regarding contribution, agreement, work plan. 4- Layout and construction under VWDC supervision with technical support from the project. 5- Treatment of catchment.
Natural / human environment: Responsibility of user group.
