I just learned to use SSA. After running the model, the average depth attained is only 0.02-0.07 ft in the Node Depth Summary. What is the possible reason? Many thanks.
Sorry. Can't answer the question without more information or a file.
The longer you run the simulation when the depth at your node is zero, your average will decrease.
Matt, you are right.
I figured it out before you replied this. Originally I used 30 days. After changed to 1 day, the average depth is reasonable.
