Description

The Zaravshan river in Central Asia is trans-boundary river originating in Tajikistan mountains and flowing to Uzbekistan. Main source of the river flow is the glacier-snow melt, and 97% of runoff is generated in the upstream part (Tajikistan). This study aims to physically analyze the available water resources of the Zaravshan river basin to provide the scientific basis to the water resources development plan in this river basin. SiBUC is used for land surface process, and global products are used for land surface parameters and meteorological forcing data. To reproduce river discharge accurately, many bias methods used for SiBUC. Such as altitude dependence correction of precipitation data and downward long-wave radiation data. However, still the discharge peak is not reproduced correctly. So in this study, the short wave radiation is also modified considering direction of the slope to simulate the glacier-snow melt process more precisely.
