without dams and the number of occasions when they were actually affected with dams

are listed in Table 7.

The Benefits due to flood control are considered to be two fold: (i) the saving of
crops, and (ii) the protection of property. The probable damage due to flood inundation
is estimated from the previous data together with the further assumptions that (a) the
intensity of cultivation is 80 per cent, (b) the average yield of the crop (paddy) is 25
maunds per acre (=2056 lb per acre), (c) the price of paddy is Rs.15 per maund (i.e.
Rs.0.18 per lb) and (d) flooding of the left-bank area causes damage to property to the
extent of about Rs.200 million, in addition to the damage to agricultural production.

On these assumptions, the losses due to damage in the Amta-Mudeswari area are put at

Rs. (300 X 0.8 X 640 X 25 X 15)= Rs.60 million. Similarly, the damage due to flooding

in the Raina area is put at Rs.40 million and that due to flooding of the left bank at

Rs.400 million.
