**课程名称：** HEC-RAS 2D 河流建模实用入门 **课程概览：** 本课程通过54个短视频教程，教授如何使用HEC-RAS水力建模软件构建1D-2D耦合模型和纯2D河流模型。课程以其Udemy上的1D HEC-RAS建模课程为基础，但内容独立，无需先修1D课程，尽管具备基本的水力建模概念会有帮助。课程提供所有必要数据，HEC-RAS软件可免费下载。 课程重点在于RAS Mapper模块的使用。您将学习如何导入、修改地形数据（包括表面插值），以及如何创建土地利用数据层生成糙度数据。随后，您将学习2D几何创建，包括设置单元格大小、调整单元格间距和对齐以最佳地表示地形和水流模式。 第一个模型将构建侧向结构，连接1D和2D区域。第二个模型将学习如何在2D模型表面表示主要河道。您还将学习输入边界条件流量数据并运行模型场景。 课程包含多个教程，详细讨论1D和2D计算选项、容差，以及如何根据库朗数设置计算间隔。您可以通过调整模型并观察计算结果来学习这些建模的各个方面。 最后，您将学习如何在HEC-RAS软件主环境中查看和操作1D结果，在RAS Mapper中查看2D输出，并掌握如何最佳地查询和显示输出数据。 **课程目标：** 本课程将帮助您将水力建模技能从仅限1D模拟提升到在地理参照地形环境中的2D建模。无论您是在学术界研究河道过程还是在河流工程行业工作，本课程都将为您打下坚实的基础。 **教学大纲：** 无
In this course you will learn, through 54 short video tutorials, how to construct a combined 1D-2D and a 2D-only river model in the HEC-RAS hydraulic modelling software package. This course, builds on my Udemy 1D HEC-RAS modelling course but is stand-alone and you do not need to take that course in order to follow and complete this one although it would be useful to have a basic understanding of general hydraulic modelling concepts.All the data necessary to follow and build your models is supplied with this Udemy course and the HEC-RAS software itself is free to download from the web.Much of the tutorial and model build will focus on the use of the RAS Mapper module within the HEC-RAS software environment. You will learn how to import terrain model data, modify it using surface interpolation techniques and how to create landuse data layers to generate roughness data. You will then go on to learn about 2D geometry creation, how to set cell size and how to adjust cell spacing and alignment to best represent the underlying terrain and likely flow patterns and, in your first model, you will then go on to create a lateral structure to connect 1D to 2D areas. In the second model that you build you will also learn how to represent a main river-channel within a 2D model surface. You will then learn how to enter boundary condition flow data and how to run model scenarios. Several of the tutorials are then focused on discussing both 1D and 2D computation options and tolerances and also how to set the computation interval based upon the Courant Number. You will learn about these various aspects of modelling by making adjustments to your model and then viewing the impact had on the computed results output. Finally, you will learn how to view and manipulate both 1D results in the main HEC-RAS software environment and 2D outputs in RAS mapper along with tips on how to best interrogate and display the output data.This course will enable you to advance your hydraulic modelling skills from 1D-only simulations to 2D modelling within a geo-referenced terrain environment and as such it will stand you in good stead whether you study river channel processes in academia or work in the river engineering industry.
