For ersuring construction safety in flood season, the owner estab-lished a leading team of flood control and prepared engineering and non-engineering countermeasures covering flood control ma-terial and staffs. Due to thorough preparation and measures implement in place, the flood control work in 2013 had been fulfilled successfully, laying foundation for realization of project goals.%2013年是南水北调中线禹州-长葛段工程建设的关键期。由于汛前渠道开挖填筑已全面成型，导致总干渠左右岸除穿渠建筑物外的水流通道被全部截断，部分河渠交叉、左岸排水等建筑物上下游连通不畅，对河道行洪、沟渠排洪安全造成重大隐患。为确保汛期施工安全，建设单位在施工现场成立了安全度汛领导小组，制定了严格的度汛措施，包括工程和非工程措施，预备了充足的防汛物质和防汛抢险人员，并加强与地方防汛部门的沟通协调。由于准备充分，措施到位，圆满完成了2013年度汛任务。
