Drainage Wells or a Vertical Exfiltration Trench
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.
