### Estimation of Total Water Consumption in the Basin (Sheet 2)  
The WA+ based sheet 2 was generated to estimate total water consumption (ET), evaporation (E), transpiration (T), and interception (I) from different water management classes in BRB. Sheet 2 was developed using the WALU map having four different water management classes. Total ET in the basin includes the amount of ET and T. The values of ET and T were evaluated for the non-manageable (actual evapotranspiration from PLU), manageable (actual evapotranspiration from ULU), and managed (actual evapotranspiration from MLU and MWU) types of WALU. The calculated values of ET and T of the basin were categorized according to the four water management classes (PLU, ULU, MLU, and MWU) of WALU. Since the precipitation years in the study were divided into dry and wet years, sheet 2 for the wet and dry years was generated separately. Sheet 2, derived for PERSIANN precipitation dataset, based a dry year (2014-2015), showed a total water consumption of 36.2 BCM/year in the basin (Figure 12). The shares of non-manageable, manageable, and managed water consumptions in the total water consumption were 0.10 BCM/year, 09.80 BCM/year, and 26.30 BCM/year, respectively. Managed land use classes have consumed more water than manageable and non-manageable land use classes in the basin. The total water consumption, split as ET and T, for PLU, ULU, MLU, and MWU were 0.1 BCM/year and 0.0 BCM/year, 09.80 BCM/year and 03.30 BCM/year, 04.10 BCM/year and 01.50 BMC/year, and 22.20 BCM/year and 09.40 BMC/year, respectively. The evaporation from the soil, water, interception, and transpiration was broken down as beneficial and non-beneficial ET. Non-beneficial ET includes evaporation from soil and open water bodies, interception from wet surfaces, such as leaves and canopies, buildings, roads, etc., and cropland-based weed infested transpiration,

The non-beneficial water consumption in the basin shared 21.4 BCM/year of the total water consumption, among which, the contributions from water, soil, and interception were 1.9 BCM/year, 18.4 BCM/year, and 1.5 BCM/year, respectively. Beneficial ET represents processes such as transpiration from different vegetative covers, evaporation from hydropower reservoirs and cooling towers, etc. WA+ regroups and labels beneficial consumptions as agricultural, environmental, economical, energy, and leisure. The beneficial component was 14.8 BCM/year, among which, the contribution from agriculture was 9.9 BCM/year. PERIANN precipitation dataset-based sheet 2 depicted that, among various water management classes in the basin, the shrubland of ULU, rainfed crops of MLU, and irrigated crops of MWU consumed a higher amount of water. Sheet 2, generated for the wet period (2016-2017), using the PERIANN precipitation dataset, shows the amount of total water consumption in the basin as 29.50 BCM/year (Figure 13). Wet period (2016-2017)-based sheet 2 depicts the amount of water consumed by non-manageable, manageable, and managed land use classes as 0.10 BCM/year, 8.1 BCM/year, and 21.4 BCM/year, respectively. During the wet period, water consumptions by shrubland of ULU (5.10 BCM/year), rain-fed crops of MLU (2.40 BCM/year), and irrigated crops of MWU (17.7 BCM/year) were found to be higher, compared to the other land use classes of the basin. The ET and T by PLU, ULU, MLU, and MWU in the basin were 00.10 BCM/year and 0.00 BCM/year, 08.10 BCM/year and 02.80 BMC/year, 3.30 BCM/year and 1.10 BMC/year, and 18.10 BCM/year and 6.80 BMC/year, respectively. Sheet 2, of the wet period, showed a total evaporation of 18.8 BCM/year. The non-beneficial component of total ET in the basin for the wet period was 18.3 BCM/year. It split evaporations by water, soil, and interception at 1.70 BCM/year, 17.00 BCM/year, and 0.00 BCM/year, respectively.
