WEAP schematic for the CRBK. The schematic includes all items in the legend except “Run of River Hydro.” CRBK basin outflow is at Billgundala (used for WEAP calibration and validation) where it flows to downstream Tamil Nadu state. WEAP catchments were formulated in accordance with modeling requirements; reservoir location (see supporting information Table S2 for details), streamflow gauge location, location of irrigated areas, demand sites, and characteristics of adaptation options. Table 2 presents the main assumptions used to convert the adaptation options into water volumes.
