Abstract:
The water availability study of Bina river
basin in Madhya Pradesh state was carried out to
estimate dependable flow at various probability levels
at different time periods and to analyze the flow
regime under virgin flow condition using Flow Duration
Curve technique. The assessment of water availability
is important for the planning of water allocation
scheme in Bina river basin to meet its on-stream
demands. From the study it was observed that the
flow regime in Bina river had been existing in virgin
condition. The study indicated that the Bina river is
an intermittent river having flow during monsoon season
only. Thus, the water use demands of the area
cannot be fulfilled from Bina river with the water availability
under the existing condition. The results indicated
that Bina river has high dependable flow during
July to September and highest in August. The
dependable flow of 28.1 m3/s at 70% probability level
and 14.06 m3/s at 90% probability level were observed
in August. The annual water availability at 75% probability
was estimated to be 432 MCM which indicated
that there was ample opportunity for harvesting water
dams in the river. The construction of dam or other
artificial structure at Rahatgarh on the river to store
water in monsoon season may be helpful to fulfill for
water requirement during non-monsoon season. The
stored water can be used for domestic, irrigation, industries,
and recreation purposes.
