The global population surge, along with uncontrolled extraction of natural resources, has increased the concentration of greenhouse gases (GHG) in the atmosphere that has caused global warming nearly everywhere on Earth. Due to global warming, regular climate patterns have been disturbed, and this change in climate has induced abnormalities in the hydrodynamics of many watersheds worldwide. That is why management of natural resources has become essential in mitigating the impacts of climate change. Activities like afforestation, river-bed restoration, innovative irrigation practices, and utilization of renewable energy are now encouraged. In this regard the two biggest obstacles faced by scientists and engineers are the unpredictability of the hydroenvironmental response to climate change and the selection or development of optimal, cost-effective, but useful mitigation options. Along with changes in climate in the near future, due to population overgrowth and uneven distribution of natural resources, urbanization will increase rapidly. The impact of climatic abnormalities on natural resources is unpredictable. The effects can only be imagined, but they cannot be determined precisely. Numerous studies have been conducted to predict the outcome of various climatic abnormalities. Scientists conceptualize climatic scenarios for the future, and simulation platforms are used to predict the outcome of these scenarios so that humankind becomes prepared for the onset of natural extremes.
