Economic Evaluation of Increasing Water Potential of Water Resources in Alborz Basin

Ab-bandans are the local and traditional water storage structures in the north of Iran which have always been regarded as the important source by farmers. Considering this fact that during the non-growth seasons a significant percentage of water of the streams، permanent and seasonal rivers fall into the sea. However، increasing the capacity of the Ab-bandans، one can store much more water in these seasons and use it in both increasing the production and substituting the rainfall land with irrigated ones. In this study، investigating the cost of dredging and improvement of 11 Ab-bandans during the 2009-2011 in the Alborz integrated land and water project area، the water potential has been measured economically. The results showed that the increase in the potential of water per cubic meter of water costs 1،900 Rials.
