Abstract:
Study was carried out the trend of groundwater status for 11 districts of Bastar plateau and Northern hill zone of Chhattisgarh. Long term groundwater level data of 27 years (1993-2019) were collected from Central Ground Water Board, Raipur (Chhattisgarh). The trend analysis of ground water level was computed with the help of Mann-Kendall method and linear trend graph method. Results were revealed that outcome of trend analysis of ground water level indicates that five districts reported significantly increasing trend of ground water at 1% level of significance i.e. Sukma, Bijapur, Jashpur, Surguja and Balrampur district whereas Kondagaon and Surajpur district showed significant increasing trend at 10% level of significance. Remaining four districts the depth of ground water level was increasing but observed it was non-significant. i.e. Koria district while Bastar, Dantewada and Narayanpur districts. The status of ground water level in most of the districts i.e. Sukma, Bijapur, Kondagaon, Jashpur, Surguja, Balrampur and Surajpur recorded significantly increasing trend of groundwater level mean ground water level was going down.
