Hydrological Response to Adapt Climate Changes
The Yellow River is a very difficulty river to harness because it is one of the most complex riven in the world.Its unique determines its hydrological characteristics of heavier task,higher requirements and more service items than that of other rivers.The Yellow River has four flood seasons.There are peach flood in spring,major flood in summer,fall flood in autumn,and ice-jam flood in winter.So it is necessary to undertake the hydrological gauging and forecasting tasks throughout the whole year for flood controlling.The main features of the Yellow River are less water and more sediment,different water and sediment origination and unmatched water and sediment relationship.Accurate and timely hydrometry is required to actualize water and sediment regulation.Meanwhile,the Yellow River is the only river in China authorized to annually allocate available water and integrally regulate water resources of the whole river due to its sharp contradiction between supply and demand of water resources.Therefore,for the Yellow River,water resources monitoring and forecasting are especially important.Moreover,along with hydrological regime changes owing to climate change plus more and mere human activities,the Yellow River hydrological work will confront much mere new challenges in the future.
