Detail Project Report IWMP 7
Salinization in the coastal area is due to the accumulation of salts from the inundated seawater. Irrigation water contains a high concentration of soluble salts;
particularly sodium salts which lead to salinity.

3.3 Rainfall vs Runoff
As 79.59 % project area lays under rainfed; so rainfall is major factor for crop productivity and also indirectly affected livelihood of the villager. Irregularity in
rainfall is major problem of farmers for success of better productivity even though fertile soil for crop. The rainfall is scanty which has resulted in recurrent
phenomenon of drought in every two to three years. The average rainfall of this area is about 804 mm (from past five year data). As Topography of project area is
hilly so runoff of rainfall water through 1st order stream (Naali) then 2nd order Stream (Nala) and 3rd order Stream (Nadi).
