2.5 Reviewing 2D Simulation Output in InfoSWMM 2D
Once the model has been successfully simulated using the Run Manager, you can review the 2D simulation output. You can review the output by creating any of three types of output objects. The following output objects are available:
· 2D Result Point… Read the rest
2.4 Set 2D Options in InfoSWMM 2D
Step 1 – Set 2D Options
It is very simple to connect the 2D Zone to the 1D underground network and to enable
the 2D simulation.
2.3 Creating The 2D Zone in InfoSWMM 2D
Step 1 – Add ground surface data to the map
Step 2 – Create 2D Simulation Polygons
2.2 Understanding the 2D Mesh (Zone) in InfoSWMM 2D
The 2D zone, alternatively described as a mesh, consists of a series of contiguous triangles, whose shared boundaries cover the catchment surface. The height of each point on each triangle is derived from a ground model GRID or TIN.
It is … Read the rest
2.1 Understanding the 1D/2D Connection in InfoSWMM 2D
The 2D Output HTML file of InfoSWMM 2D shows the Total 2D Inflows at each node by Mesh ID. You can either graph, report use the 2D Graphs in InfoSWMM to also see these flows but in addition there is a Section … Read the rest

Infiltration is the process of rainfall penetrating the ground surface into the soil over the pervious areas of Subcatchments.
InfoSWMM H2OMap SWMM InfoSWMM SA offers three choices for modeling infiltration:
Horton’s Equation
This method is based on empirical observations showing that infiltration decreases exponentially from … Read the rest
