Hydrometeorological consequences on the water balance in the Ganga river system under changing climatic conditions using land surface model

The United Nations Sustainable Development Goal (SDG) ensures adequately accessible water and management for all. Due to the rapid increase in population industries along Ganga river, it is necessary estimate budget fulfill demand future. Mann-Kendall (MK) test conducted on Noah-Land Surface Model data 72 years results a maximum declining trend of Yamuna Lower (Q = ?3.82 BCM/year), minimum Damodar sub-basin ?0.10 BCM/year). All sub-basins show an groundwater level (mbgl) except Kali Sindh, which shows decreasing ?0.07 m/year). percentage change was also estimated all sub-basins, including various parameters such as precipitation, evapotranspiration, runoff, budget, temperature. extremely severe drought using Standard Groundwater Level Index (SGWLI), from values Ram Confluence (SGWLI 2.44; 2005), Upper stream Gomti 2.06; 2014), Ghaghra 2.22; 2.28; 2.13; 2007), Sindh 2.30,2.67; 2002, 2003), Chambal 2.30,2.20; 2001, Son 2.02; 2010), Gandak 2.37; Kosi 2.08; 2012), 2.72; Bhagirathi 2014) were obtained total 62,050 observed well data.The in-situ point converted into surface raster geostatistical technique. Our 19 basin several parts.
