- Response of sediment flow behavior to storm type and spatial scale in purple soil watershed
紫色土区小流域泥沙输出过程对雨型和空间尺度的响应 - The overall plan for xiaolangdi project management zone is carried out to ensure the safe operation of hydraulic constructions in the zone , to make full use the advantages of location and resources of the area , and to realize the general objective of “ mainly aim at flood prevention including ice flood prevention and sedimentation reduction , and give consideration to water supply , irrigation , power generation , storage of clear water and discharge of sediment flow , alleviating disaster and bringing about benefit , and comprehensive utilization " , for the project development
为确保小浪底水利枢纽工程管理区内水工建筑物的安全运行，充分发掘管理区的区位优势和资源优势，实现“防洪（包括防凌） 、减淤为主，兼顾供水、灌溉、发电、蓄清排浑、除害兴利、综合利用”的工程开发总目标，对工程管理区进行了总体规划。 - Due to issues of dongting lake districts flood composition , the evolution of sediment flow , the river and lake ( r & l ) distribution characteristic as well as the layout of r & l - dredging engineering , the article simulated the model of the dongting lake terrain change by using the gis technology and adopted the limited volumetric method to establish the two - dimensional hydraulics computation model of lake in order to forecast the water level , the flow capacity , the speed of flow and changes of flow field after implemented the project , which have provided the reliable theoretic basis for the decision - making and implementation of renovation for river course , canal and harbor and river course - dredging engineering
摘要针对洞庭湖区的洪水组成、水流泥沙演变、河道湖泊水系分布特点以及河道湖泊疏浚工程布局情况，利用gis技术模拟洞庭湖地形变化，采用有限体积法建立了湖泊二维水力学计算模型预测疏浚工程实施后的水位、流量、流速流场变化，为河道、航道港口整治、河道疏浚清淤等工程决策与实施提供了可靠理论依据。
