什么是GeoHECRAS 2D？

GeoHECRAS 2D显着加快了1D和2D HEC-RAS 模型的创建和审查，能产生更好和更精确的结果。2D桥梁建模、FEMA 2D漫滩侵蚀建模、2D溃坝建模和2D溪流修复只是可以利用GeoHECRAS 2D快速完成的其中一些项目。自动网格生成、自动不良单元固定、自适应网格划分、二维运输障碍物和自动网格细化大大提高了工程生产率。而且，由于GeoHECRAS 2D是美国陆军军团部队
HEC-RAS软件的数据包装器，因此在 HEC-RAS 中的所有操作都使用GeoHECRAS的AutoCAD
兼容图形用户界面。

使用自动化工作流更快地工作：

与HEC-RAS兼容的AutoCAD、MicroStation和ESRI ArcGIS图形界面

GeoHECRAS 2D是一个与AutoCAD、MicroStation和ESRI ArcGIS兼容的交互式2D/3D图形用户界面数据包装器，适用于美国陆军军团部队HEC-RAS软件。

将各种不同的数据快速方便地导入到HEC-RAS中

导入现有的陆军军团HEC-RAS模型，并使用包含的地理参照工具快速地将其地理参照到真实世界的地图中。

在多个HEC-RAS模型上同时工作

使用多文档接口(MDI)同时处理多个HEC-RAS项目，包括在HEC-RAS项目之间复制和粘贴截面和其他数据。

工作流程

The Draw 2D Mesh Face command allows the user to draw a mesh patch (or mesh template) and direct the software to honor the drawn patch when generating the mesh. The user can draw element face lines and construct 3-sided and 4-sided mesh elements to make a mesh patch. The command gives the user the ability to control how the HEC-RAS 2D cells are created in areas where a high level of detail is required, such as when 2D cells need to be placed and aligned to satisfy culvert inlet and outlet locations.

绘制二维网格面

Draw 2D Mesh Face命令允许
用户绘制一个网格贴片（或网格模板），
并在生成网格时指导软件兑现绘制的贴片。

The 2D Floodplain Encroachment command automates the placement and analysis of floodplain encroachments along the river reach when performing a 2D steady or unsteady flow computation. This allows the modeler to have a better understanding of the true flow effects when attempting to determine the floodway in a complex flow situation. The modeler can examine the VxD (velocity x depth) factor, as this directly indicates greater flood hazard and hydraulic importance.

二维河漫滩侵蚀

二维河漫滩侵蚀命令在执行二
维定常或非定常水流计算时，
使河段河漫滩侵蚀的放置和分析自动化。

In addition to HEC-RAS’ default rectangular (structured) 2D computational mesh, the software can create an adaptive 2D mesh to better represent more complicated 2D flow conditions and structures. The software will automatically refine the 2D mesh where required, such as at a roadway crossing bridge opening.

自适应二维网格

除了HEC-RAS默认的矩形（结构化）二维计算网格外，该软件还可以创建一个自适应的二维网格，以更好地表示更复杂的二维流动条件和结构。

Plot moving particles on the flood map to represent the flow field for both 1D river reaches and 2D flow areas. The size and speed of the particle is adjusted to represent the velocity at that point. Particle tracking maps can be created for both steady flow and unsteady flow models.

粒子跟踪图

在洪水图上绘制运动粒子，以表示一维河段和二维流区的流场。

Incorporate 2D flow training structures for river and stream restoration projects. Define river structural measures to improve the flow of the river and maintain the channel within the floodway, preventing and reducing river channel migration during flood events. Protect critical infrastructure, like bridge roadway crossings, by directing river flow through the bridge opening during extreme flow events

二维流训练结构

纳入河流和溪流恢复项目的二维水流训练结构。确定河道结构措施，以改善河道的流量，维护河道在洪道内，防止和减少洪水事件期间河道迁移。

Ineffective flow areas can be assigned to the 2D mesh using polylines or polygons. Alternatively, draw ineffective flow areas on the Map View. For example, stagnant flow areas at roadway crossings can be stamped into the 2D mesh to account for the ineffective flow area. The software will automatically refine the 2D flow area to incorporate the ineffective flow area shape.

二维无效流动区域

无效流动区域可以使用折线或多边形分配给2D网格。或者，在地图视图上绘制无效的流区域。

Conveyance obstructions can be assigned to the 2D mesh using polylines or polygons. Alternatively, draw conveyance obstructions on the Map View. For example, buildings and other structures can be stamped into the 2D mesh as conveyance obstructions to account for flow blockage. The software will automatically refine the 2D flow area to incorporate the conveyance obstruction shape.

二维运输障碍

可以使用折线或多边形将运输障碍物分配给2D
网格。或者，在地图视图上绘制运输障碍物。

The Army Corps of Engineers HEC-RAS software generates 2D meshes that contain elements that are marked “bad” and require manually fixing by the user. GeoHECRAS will automatically detect and fix these bad elements without requiring any interaction by the user.

自动修复二维网格坏元素

陆军军团团的HEC-RAS
软件生成的2D网格包含被标记为“坏”的元素，需要用户手动修复。

As you modify the 2D mesh by inserting additional elements, moving elements, and performing other mesh element editing, the software remembers these edits. Then, the next time the 2D mesh is rebuilt, these user-defined changes are automatically incorporated into the mesh.

记住2D网格用户编辑

当您通过插入附加元素、移动元素和执行其他网格元素编辑来修改2D网格时，软件会记住这些编辑。

Assign land cover polygons and/or National Land Cover Database (NLCD) data as Manning’s roughness to cross sections and 2D flow areas. The National Land Cover Database provides land cover data for the entire United States. The software can dynamically download a NLCD raster land cover grid for the area being modeled. Each 75ft x 75ft land cover grid cell represents a specific land type. Up to 20 different land types and corresponding Manning’s roughness values are provided.

分配土地覆盖数据

将土地覆盖多边形和/或国家土地覆盖数据库(NLCD)数据作为曼宁粗糙度分配给横截面和2D
流动区域。

Export flood map animations to Google Earth. This is helpful for presentations on flood risk assessment and flood management.

Google Earth地图动画

导出洪水地图动画到谷歌地球。这有助于洪水风险评估和洪水管理的演示。

For unsteady flow models, the flood map can be animated to show how it changes with time. The animation speed can be adjusted, as well as set up to loop continuously. The final animation can be recorded to a video. In addition to animating the flood results, options are available to show the extent of the maximum and minimum flood areas.

洪水动画图

对于非恒定流模型，洪水图可以被动画化，以显示它是如何随时间变化的。

Plot velocity vectors on the flood map to represent the flow field for both 1D river reaches and 2D flow areas. The velocity vector length is adjusted to represent the velocity at that point. Velocity vector maps can be created for both steady flow and unsteady flow models.

速度矢量图

在洪水图上绘制速度矢量，以表示一维河段和二维流区的流场。
