Water-use accounts in CPWF basins: Simple water-use accounting of the Karkheh Basin
This paper applies the principles of water-use accounts, to the Karkheh River basin in Iran.
The northern part of the Basin where the Karkheh and its tributaries rise is mountainous, cooler, and wetter. The River spills out on to the hotter, lower semi-arid plains at its southern end. Precipitation, mainly in winter, varies from 400-500 mm in the upper part of the Basin falling to about 230 mm in the lower reaches.
