东喜马拉雅地区易贡溃决洪水HEC-RAS水动力学模拟（2000）

数据为2000年易贡滑坡溃决洪水HEC-RAS模拟所需要的输入和输出文件。输入文件包括建立工程，几何数据，边界条件、初始条件和流量过程等数据。输出文件包括水流深度、流速、剪切力、水面高程、水流功率、Froude数等数据。模拟输出数据以HDF形式储存，HDF是一个科学计算用的大数据集，专用于存储大量数据的，根据请求实时加载渲染，这种方式速度快，体积小，只能在HEC-RAS中查看。该数据将为溃决洪水演化、侵蚀机理及其侵蚀和沉积地貌效应等研究提供有力的数据支撑。

The dataset consists of input and output files required for the HEC-RAS simulation of the 2000 Yigong landslide dam-break flood. The input files include data such as project setup, geometric data, boundary conditions, initial conditions, and hydrographs (flow processes). The output files contain data including flow depth, flow velocity, shear stress, water surface elevation, flow power, and Froude number. The simulation output data is stored in HDF format. HDF is a scientific computing-oriented large dataset specifically designed for storing massive volumes of data. It enables real-time loading and rendering on demand, featuring high speed and small storage footprint, and can only be viewed using HEC-RAS. This dataset provides robust data support for studies on dam-break flood evolution, erosion mechanisms, and their erosional and depositional geomorphic effects.
