(2007). A more than two-fold increase in November through January precipitation was also predicted by 2075; however, that increase will have limited influence on the annual hydrological budget because November to January accounts for only 6% of the annual precipitation. The predicted changes in the Brahmaputra precipitation over the 21st century by 25-year epoch presented a similar pattern for annual cycle and magnitude of the change (Pervez and Henebry, 2014). The impacts

of climate and land use change on the hydrological components of the Brahmaputra basin are presented in Fig. 6b–f. In response to an expected Depsipeptide datasheet increase in annual precipitation, the loadings in the hydrological components were predicted to increase annually with seasonal variability relative to the baseline (Table 6). Under the A1B and A2 scenarios, the total water yield was projected to increase by 9% and 10% annually. Fig. 6b indicates an increase in total buy PS-341 water yield in all seasons except the early monsoon months of May, June, and July. During this period, total water yield was predicted to decrease principally because of a decrease in precipitation and an increase in temperature.

May through July accounts for 33% of the annual total water yield; therefore, 15% and 18% predicted decreases in water yield will potentially increase the drought risk during these months under the A1B and A2 scenarios, respectively (Table 6). Later in the monsoon, August, September, and October, total water yield was projected to increase by 17% and 20% under the A1B and A2 scenarios, respectively. August through October is the wettest period of the year, accounting GBA3 for 51% of the annual water yield. An increase in water yield will potentially elevate the flooding risk between August and October in the

basin. Water yield was expected to increase over the dry period from November to April, which might be helpful to mitigate the prevailing dry conditions in those months. The climate and land use change impacts on soil water content was predicted to increase by 7% and 8% annually, with most of the increase being predicted during November to January (13% and 15%) and the smallest increase being predicted during May to July (2% and 3%) under the A1B and A2 scenarios, respectively (Fig. 6c). Increased soil water content and increased temperature would potentially increase ET in the basin. ET was projected to increase annually by 5% and 7% for the A1B and A2 scenarios, respectively; however, it was predicted to decrease during the early monsoon months of May through July by about 4%, primarily because of the combined influence of reduced precipitation and increased physiological forcing (Fig. 6d). In contrast, average ET was predicted to increase by 12% and 14% due to increased soil water content and temperature between August and April under the A1B and A2 scenarios, respectively.
