摘要

本课程设计主要针对C水库水利水电规划设计进行兴利和调洪等计算，根据年径流资料和洪水等资料推求该流域径流过程及洪水过程线，进而推求C水库各特征水位、水电站各项指标以及大坝高程等数据。通过该课程设计更好地巩固了对水文分析计算和水利计算的知识掌握情况，培养了分析解决实际工程问题，并通过科学手段进行计算，进而完成报告编写的能力。

Abstract

This Curriculum design is mainly aimed at the planning and design of water conservancy and hydropower resources for C reservoir, which includes the beneficial purpose calculation and reservoir flood routing. Based on the annual runoff data and flood data, it deduces the runoff process and flood process line of the basin, and then deduces the data of water level of C reservoir, various indexes of hydropower station and dam elevation. By finishing the Curriculum design, the knowledge of hydrologic analysis and calculation and water conservancy calculation are better consolidated, and the ability to analyze and solve practical engineering problems and calculate by scientific means to complete the report writing is cultivated.
