Detailed explanation-1: -Despite being the cradle of Chinese civilisation and the nation’s second-longest river after the Yangtze, the Yellow River’s potential has been stunted, because of unsustainable use of water, soil erosion, sediment and pollution.
Detailed explanation-2: -There has long been a good understanding that such misery is caused by the high concentration of sediment the river carries, which renders it yellow. When deposited downstream, this sediment raises the riverbed, making it prone to flooding or changing course.
Detailed explanation-3: -It is estimated that human activities, such as destruction of natural vegetation, have augmented natural soil erosion by about 40% in the basin. Water-related disasters are another major issue in the basin.
Detailed explanation-4: -The worst flood in human history occurred in 1887, when the Yellow River overran the dikes in Henan Province. That flood covered 50, 000 square miles. It inundated eleven large towns and hundreds of villages. Nine hundred thousand people died, and two million were left homeless.
