Example Application 应用程序实例 This chapter provides an example application of how to perform steady flow water surface profile calculations with HEC-RAS. 这章提供一个关于如何应用HEC-RAS执行稳定流水面线计算的实例。The user is taken through a step-by-step procedure of how to enter data,perform calculations, and view the results.用户可以通过一步步程序，了解如何输入数据，执行计算以及查看结果。 In order to get the most out of this chapter,you should perform each of the steps on your own computer.为了获得除本章之外的更多知识，你最后在你自己的电脑上执行每一个步骤。 Also,before you try the example application ,you should have read the first three chapters in this manual.当然，在你尝试这个应用实例之前，你应该阅读本手册的前三个章节。 Contents 本章内容 Starting a New Project 开始一个新工程 Entering Geometric Data 输入几何数据 3. Performing the Hydraulic Calculations 执行水利计算 4. Viewing Results 查看结果 5. Pringting Graphics and Tables 打印图表 6. Exiting the Program 退出程序 Starting a New Project 开始一个新工程 To begin this example, Let’s first start the HEC-RAS program. 开始这个例子，我们先打开HEC-RAS程序，Double click the HER-RAS icon in Windows.在Windows界面中双击 HEC-RAS 图标。 The main window should appear as shown in Figure 4-1.(Except yours will be blank the first time you start the program).主窗口会出现如图4-1。（如果你是第一次打开这个程序窗口是空白的） The first step in developing an HEC-RAS application is to start a new project. 应用 HEC-RAS 运行计算的第一步是建立一个新的项目。Go to the File menu on the main window and select New project. 在主窗口的文件（File）菜单里选择“新建”项目（New Project）。The New Project window should appear as shown in Figure 4-2(Except the title and file name fields will be blank when it first comes up).“新建项目”窗口应该会出现如图4-2所示。（除标题和文件名第一次出现时字段将是空白） First set the drive (e.g.,c:) and the directory that you would like to work in.首先选择驱动器（如C盘）和你想要的工作目录。 Next enter the project title and filename as shown in Figure 4-3.接下来输入项目名称和文件名如图4-3所示 Once you have entered the information ,press the OK button to have the data accepted.当你输入这些信息后，单击OK按钮保存数据。 Entering Geometric Data 输入几何数据 The next step in developing a steady flow mod
