| Popis: | The Helmand River Basin is a closed river basin in (semi)arid southern Afghanistan, Iran and Pakistan. Irrigation is by far the largest surface water use. Two of the three main rivers have large dams that regulate river flow for irrigation and hydropower. Water management in the basin faces a number of challenges, among which are insecurity, collapse of the river flow monitoring network in the Afghan part of the basin in 1980, inefficient operation and maintenance of existing water infrastructure, many drought years since 1999, reduced upstream water storage due to siltation of reservoirs, and a possible future reduction in snow storage as a result of a predicted temperature rise. The paper presents: (1) an overview of water resources and water management in the Helmand River Basin, where data are scarce and difficult to access; (2) a description of innovative methods used to generate simulated flow data for the basin, including the use of globally gridded data sets; (3) a discussion of how the reservoirs... |
