Effects of Rainfall Factor on Hydrogeological System Recharge in Bangar Environs: A Middle Part of India

Rainfall is one of the vital hydrometrological factors that govern the phenomena of groundwater system recharge. The results of rainfall data analysis of Bangar area of Dewas district located in Madhya Pradesh, India, and their environmental effects on groundwater system have been in corporate here in this paper. Rainfall phenomena reflect environmental scenario particularly climate change the data are subjected to several techniques of analysis. The years revealing more than the average annual rainfall values indicate positive recharge trend. The years reflecting less than the average value indicate negative trend of recharge to groundwater system. Cumulative departure exhibit positive and negative trends and the determination of moving rainfall average provide a picture of cycle variation of rainfall trend. Rainfall departure trend indicates higher values which reflect positive trend of recharge. Mathematical analysis indicate both positive and negative trend of groundwater recharge. Statistical analysis rainfall data have been determined value of mean, median, mode and the co-efficient standard deviation, co-efficient of dispersion, co-efficient of variation and co-efficient of skewness. The statistical data prove the validity of rainfall data. Environmental effects of rainfall factor have been discussed. It is suggests that implementation of a rainfall augmentation sachem would provide appropriate rainfall recharge to the groundwater system and it would also resolve the water crises problem.
