A study was carried out to determine the effect of climate
change on design rainfall and its effect on design and
costing of soil and water conservation structures In watersheds. For this study, the micro watershed
located at Central Soil and Water Conservation
Research and Training Institute, Research Centre,
Research farm, Vasad was selected and rainfall data
from 1957 to 2012 was used. The analysis showed that
as a result of climate change, there is significant increase
in number of extremely heavy rainfall days as
well as rainfall amount. The design rainfall of various
soil and water conservation structures has increased
by 11%, 30% and 38% for design of staggered contour
trenches, contour bunds and check dams respectively.
The cost of construction of staggered contour
trenches, contour bunds and check dams in watersheds
has increased by 26%, 28% and 12% respectively.
This study reveals that, there is a need to
account for design and costing of soil and water conservation
structures in the light of the climate change
and a relook into the watershed programmes of the
central Gujarat region of India.
