Impact Of Climate Change On Rainfall And Ground Water Level In Kanpur City.

Abstract

Any location's rainfall directly and indirectly influences the local Environment, people's livelihood, food, and drinking water. Analysis of Rainfall helps to provide input for planning for renewable energy projects, agricultural practices, etc. It is also used to predict natural disasters like drought and flood, which creates Uncertainty in the water supply and its management. The present study explores the relationship between the long-term rainfall pattern (2010-2022) and the water level fluctuation in Kanpur Nagar. The district experienced an average annual rainfall in Kanpur Nagar is 821.09mm. Intergovernmental Panel on Climate Change predicted that 1861 the global mean surface temperature has increased by 0.6- 0.2℃ since 1861 and estimated an increase of 2 to 4℃ over the next 100 years. The rise in Temperature also affects the hydrological cycle by directly increasing evaporation and evapotranspiration. As a result, these changes affect the amount of precipitation, and intensity indirectly impacting the influx and storage of surface and underground water. The fluctuations in the water table also show a declining level compared to previous decades. The variations in rainfall and water level are related to the EL-Nino and La Nino effects. The change in climate variables, such as air temperature, precipitation, and evaporation, directly impacts surface water resources. Impact surface water resources. The intense cultivation of water-intensive crops is the major cause of fluctuation in water level. Create artificial water recharge and Replace water-intensive cropping patterns by cultivating less water-consuming crops with efficient water management technology, which may help to overcome future distress conditions. The greater changeability in rainfall could mean more continuous periods of high and low groundwater-level saline intrusion in coastal aquifers due to rising sea levels. levels. Groundwater resources in a straight line related to climate change through the direct interaction with surface water resources. Therefore, measuring the impact of climate change on groundwater resources provides not only authentic forecasting of change in the utmost climate variable but also accurate evaluation or prediction on groundwater recharge.
