• The encroachment of the lower reach of
Mundeswari by agriculture and brick industry
should be prevented by the joint endeavor of
State Govt., DVC as well as local administration and politicians by providing proper
rehabilitation.
6.6.2 Controlling Measures
of Mukutmonipur Barrage
• Reduction of siltation from the Mukutmonipur
Dam.
• Reduction of water through the cyclonic period with above danger level to reduce pressure
from the dam.
• Increase the carrying capacity of Mukutmonipur Barrage to store excess water.
• Several small dams may be constructed in the
upstream of Mukutmonipur dam to reduce
pressure from the main dam.
• The uncontrolled discharge of River Darakeswar should be regulated in a scientific
way and appropriate plan should be taken up
in this regard.
6.7 Reducing Flood-Peaks
by Volume Reduction
The Damodar Valley Reservoirs play an important role for the reduction of flood peaks by
discharge reduction. Examination of actual
inflow and outflow data for the two terminal
dams at Maithan and Panchet shows that tangible
flood moderation has been achieved during the
past years. Table 6.5 shows the performance of
these reservoirs in terms of major flood inflows
into these reservoirs and the moderation
achieved. All flow figures are in cubic meters per
second.
It is evident from the above table that flood
moderation to the extent of 53% to 80%had been
achieved in the high flood-years. Detailed
examination of flow data as available at Rhondia
revealed that maximum flow of 650,000 cusec
