to study the catchment area in your surroundings and suggest measures for its development . Hypothesis:
Answers
Answer:
Generally speaking, for the optimal functionality and longevity of a dam or reservoir of
hydropower projects, it is essential to limit and minimize the sediment intake to minimum level. It is
a well established fact that reservoirs formed by dams on rivers are subjected to sedimentation. The
process of sedimentation embodies the sequential processes of erosion, entrainment, transportation,
deposition and compaction of sediment. The study of erosion and sediment yield from catchments is
of utmost importance as the deposition of sediment in reservoir reduces its capacity and thus
affecting the water availability for the designated use. The eroded sediment from catchment when
deposited on streambeds and banks causes braiding of river reach. The removal of top fertile soil
from catchment adversely affects the agricultural production. Thus, a well designed catchment area
treatment plan is essential to ameliorate the above mentioned adverse processes of soil erosion. In
hilly area, as in the present case, erosion due to water is a common phenomenon and the same has
been studied as a part of the Catchment Area treatment (CAT) plan. Hence, it is necessary to adopt
corrective measures in the catchment area so as to reduce the sediment load. Therefore, Catchment
Area Treatment (CAT) plan is an integral part of most of the hydropower development project that
pertains to preparation of a management plan for treatment of erosion prone area of the catchment
through biological and engineering measures. The main impact of soil erosion and its consequences
Explanation:
Explanation:
To reduce the aforementioned harmful processes of soil erosion, a well-designed catchment area treatment plan is crucial. Water-induced erosion is a common occurrence in hilly areas like the one in the current case, and the same has
the Catchment Area Treatment (CAT) scheme has been studied. Therefore, it is essential to implement remedial actions to lower the sediment load in the catchment area. Consequently, Catchment.An essential component of the majority of hydropower development projects that concerns the creation of a management plan for the catchment's erosion-prone section.
through engineering and biological methods. The major effects of soil erosion and their repercussions are:
loss in the production potential
reduction in water holding capacity
loss of nutrients
reduction in water supply
increase in tillage operation costs
reduction in infiltration rates
