Description:
<jats:p>Torrential floods have caused great material and economic damage in Serbia,
in the past and even more frequently nowadays. Definitely, the reduction of
negative consequences can be achieved by taking preventive measures which
include integral basin arrangement. The economic justification of investment
in the protection against torrential floods includes a specific approach,
especially when it comes to technical facilities in this area. On the basis
of the example of flood control on a part of the river Ljubovidja, variants of
protection were selected on the basis of economic criteria. On the basis of
the techniques of avoided damage, evaluation of the economic effects of
provided embankments for flood control was done using dynamic methods: the
cost-benefit relationship and net present value. It was concluded that the
second option is more economical, even though it does not protect the whole
area from floods, because a part of that role would be taken over by the
intended dam in the upper flow of this river.</jats:p>
