Basania Project: -
C = 60
A = 9472 sq.km
Therefore, Q = 60(0.386x9472)
= 14,694 cumec
{0.925 – (1/14) log(0.386x9472)}
Preliminary Feasibility Report
Basania HE Project 3 X 30 MW
As design flood discharge obtained by using empirical formulae is on lower side
as compared with 39,368 cumec mentioned in report prepared by MPEB
obtained by using design storm on 19 to 20 September 1926 having Bichhia as
centre and Snyder unit hydrograph. Therefore, design flood value may be
adopted as 39,368 cumec for present study. Further studies by using unit
hydrograph theory and flood frequency analysis will be conducted at the time of
preparation of feasibility report with more databases.
5.6 SEDIMENTATION
The annual sediment rate per square kilometer of drainage area per year is
available at G&D site Manot on River Narmada and at G&D site Mohgaon on
River Burhner, which are shown in Table 5.6. These two G&D site is about 5 km
and 16 km upstream of proposed dam site Basania. The sediment rate at
proposed dam site Basania is worked out as average of the above mentioned
two G&D sites. Thus, sediment rate is 0.070 Ham/sqkm/year as calculated in
Table 5.6.
