Hydrological cycle also termed as the water cycle is the journey made by water as it circulates in the planet from the land to the clouds or skies and back again. The sun’s heat provides energy that necessitates evaporation of water from the earth’s surface. Also, this happens to plants too as they lose water to the atmosphere and is commonly referred to as transpiration. The water vapor eventually condenses and hence forms some tiny droplets in the clouds. Indeed, after the clouds meet the cool air over the land a process termed as precipitation is triggered where the water returns to the sea or land. After precipitation occurs the water soaks in the ground forming the ground water which in turn infiltrates the soil.

The coastal population would suffer greatly if these changes in climate happened. Water quality in particular is likely to be salinized affecting the population greatly as well as increasing the salt quantities in the water supplies (Goel, P. K, 2006, p.28). A rise in the sea levels would increase salt concentrations in the groundwater and estuaries. Further, the areas affected by salinity would be extended thus decreasing freshwater in the coastal areas. Lack of fresh water will lead to various human diseases and will pose to be a huge problem as drinking water would be scarce.
