| 1 | DIVERTING SEAWATER TO SCOUR THE ESTUARY-A QUEST FOR NEW APPROACH TO REGULATETHE LOWER YELLOW RIVER-显示文摘The Lower Yellow River is an above-the-ground river. Flood control has always been a critical problem.Although prolong dry spell and large-scale withdrawal of river water by the riparian people have causedthe river to dry up for a certain period every year since 1972, flood is still threatening, because a dry spellmight well be followed by a wet one in the future. During the past dry years. however, the main channelhas been silted up in many places because of inadequate flow for the transport of heavy sediment load.The stages for the same flood would then be higher and the flow pattern more unpredictable. The leveesare thus exposed to greater danger. In order to restore the main channels, scour by diverting seawater isproposed. Altogether about 360 km of the river may be deepened. In addition to scouring, discharge ofturbid saline flow to Bohai sea would help ease the ecological and environmental problems there. Thefresh water supply of the estuarine area may be increased by trading the fresh water flow originally setaside for scouring with that of seawater. | Bingnan LIN1 Jianjun ZHOU2 and Ren ZHANG2(1Prof. and Dir.
