University of East Anglia: According to new research, rising global temperatures are putting river basins around the world, including India, at risk of flooding.
Even a little temperature increase of 1.5 degrees Celsius, according to a study from the University of East Anglia (UEA), will pose substantial hazards to regions of India, China, Ethiopia, Ghana, Brazil, and Egypt.
Climatic Change is the journal where the findings were published. The researchers looked examined the dangers of fluvial floods at six different global warming levels by 2100, ranging from 1.5 to 4 degrees Celsius.
The study looked at six countries that are all regarded to be sensitive to climate change, all of which are located on different continents, have varying levels of development, and are of varying sizes.
Monthly observations, daily reanalysis data, and projected changes in the five CMIP5 climate models were used to create daily time series of precipitation, temperature, and monthly potential evapotranspiration (Coupled Model Intercomparison Project Phase 5, Global Climate Models).
The hydrological and hydrodynamic models were then utilised to simulate river discharge and flood inundation using these series.
"Our findings show that the return periods of one-in-100-year floods in the late 20th century are expected to decrease with warming, putting a larger number of people at danger of flooding," said Dr Yi He, Associate Professor at the University of East Anglia's School of Environmental Sciences.
