Getting Started on the CAD Side
When you are getting ready to perform hydraulic or hydrologic computations using SSA, there are several steps that can be completed on the CAD side of Civil 3D.
You will use Civil 3D tools to find drainage points, catchment areas, and flow paths.
In any hydrologic system, it is important to know the direction water will flow on a surface. The Water Drop command is an excellent tool for determining where your outfall location should be. You will want to locate preliminary flow paths before defining the drainage basin.
To use the Water Drop command, select the surface you wish to analyze. Then select the ...
