Figures & data
Figure 1. Map of the Aksu headwater catchments and irrigation systems along the Aksu River (top) and true-colour composite satellite imagery of the region (~2020, bottom).
Table 1. Glacier contribution to total runoff for the Sary-Jaz River (measured at Xiehela station) and Kokshaal River (Shaliguilanke station); data sources glacier melt: Duethmann et al. (Citation2015), Pieczonka and Bolch (Citation2015), Zhao et al. (Citation2013), data source runoff: Yu et al. (Citation2011). The glacier contribution was calculated for the priod after 2000. No runoff data was available for the period after 2008. We consider the period 2000-2008 to be also representative for the period until 2020

Projected future changes in annual mean discharge of Sary-Jaz and Kokshaal catchments simulated by SWIM-G and WASA relative to the baseline period 1971–2000 for three different RPC scenarios (A); Projected seasonality changes in runoff for Aksu River (B), data source: Wortmann et al. (Citation2021)
