自古以来,洪水灾害一直困扰着印度部分地区,其洪涝地区占全国土地总面积的1/8,约40万km~2。全国几大河流流域内,每年都出现不同程度的洪水,并造成人员和财产损失。因而,采取必要的防洪措施以减轻水害威胁成为印度水利部门的重要任务之一。 Since ancient times, flood disasters have plagued some parts of India. Its flooding area accounts for one eighth of the total land area of ​​the country, about 400,000 km 2. In several major river basins throughout the country, floods of varying degrees occur every year, resulting in loss of people and property. Thus, taking the necessary flood protection measures to mitigate the threat of water damage has become one of the important tasks of the Indian water sector.
