Tsu i fish structu re is adop ted to so lve the backwater and in tru sion of m ain rivers. W ith its flow in to the reache s of the river through the end of the h ighe st flood level, the smooth deb ris drainage is realized. The scien tific and techno logical innovation in th is p ractice is qu ite referen tial to other p rojects.
