Subject: Drainage Wells or a Vertical Exfiltration Trench in InfoSWMM Note, this is just one way to model an Exfiltration Trench. The source for the image below is Rice Creek Watershed . You can make a storage node to simulate the trench with the following characteristics: · Functional or Shape Curve to describe the shape of the trench, · Infiltration parameters to simulate the infiltration flow out of the bottom or sides of the trench, Step 1: Define the shape and geometrical characteristics of the Infiltration Trench Step 2: Define the soil infiltration characteristics of the trench Step 3: Run the simulation. The Storage Volume Summary tells you the volume infiltrated and the average outflow. Step 4: Output Manager will also show the infiltration outflow, the depth and the volume of the infiltration/storage node. Step 5: Infiltration losses out the side and bottom of the orifice.
