Calculating design flood under the context of climate change - a case study in the south central and central highlands area
Currently, under the impact of climate change (CC), the phenomenon of extreme and against-the-order-of-nature weather appears more and more. Floods often occur suddenly, causing a great deal of damage to people and property. The South Central and Central Highlands have short and steep terrain and ar...
