Watershed <strong>Development</strong> Works<br />
Watershed development works are to be done during second phase <strong>of</strong> watershed project. A multi-tier ridge to valley sequence approach<br />
should be approached towards implementation <strong>of</strong> watershed development projects. A net budget <strong>of</strong> 50 % is allotted for this work.<br />
Following three types <strong>of</strong> works are to be take in the work phase<br />
a) Ridge Area Treatment<br />
Main objective <strong>of</strong> ridge area treatment is to Slowing down the velocity <strong>of</strong> run<strong>of</strong>f, checking soil erosion and improving local soil<br />
moisture pr<strong>of</strong>ile.<br />
b) Drainage Line Treatment<br />
Main objective <strong>of</strong> drainage line treatment is to reducing soil erosion, trapping silt which slows the rate <strong>of</strong> siltation in wat er<br />
harvesting structures in the lower reaches <strong>of</strong> the watershed, creating a hydraulic head locally which enhances infiltration <strong>of</strong> surface<br />
run<strong>of</strong>f into the groundwater system; and increasing the duration <strong>of</strong> flow in the drainage line.<br />
c) Land <strong>Development</strong><br />
Main objective <strong>of</strong> land development is to reducing soil erosion by slow down <strong>of</strong> the run<strong>of</strong>f, to maintain the soil moisture and to make<br />
soil fertile by different types <strong>of</strong> treatments.<br />
