As indicated above, most of the streamflow originates from the snow melt, glacier melt, and orographic rainfall in the mountainous areas around the TRB. To effectively estimate the surface water fluxes over the irrigated area, the discharge data from 1961 to 2007 observed at the five hydrometric gauges monitored by the Xinjiang TRB Management Bureau were selected as part of the routing model inputs. The hydrometric gauges are located upstream of the reservoir system and the irrigated area (Figure 1). In addition, information on a series of major reservoirs operated by a local agency is collected to parameterize the reservoir module, which is included in the routing model. Detailed information on the hydrometric gauges and reservoirs is listed in Tables 1 and 2.
