### Shape Curve Viewer

Hello everyone,

I'm modeling a a simple sewer system. For that I need to define the specific geometry for each sewer of the system. However, when I introduce it, the shape curve viewer only show me the bottom half of my sewer.

Is it simply a problem wi

### Overland Flow length computation in ArcGIS

I tried to estimate the length of overland flow using Flow Direction and Flow Length tool in ArcGIS. But the problem is that my sub catchments are mostly of rectangular shape (i.e. not he originally delineated sub watershed).

I would like to make one

Dear Bob

I am trying to design a pond in SWMM where I want to maintain atleast 1m depth of water before allowing the discharge from the pond. For this I have given 1m initial depth of water in the pond and kept its height as 2.5 m, but while simulatin

### VARIABLE_STEP format

Hello everyone,

I just started working with swwm 5.1 and I'l already stuck... I try a very simple model to understand how the software works and I can't run anything at all.

Here is the example I'm working on (in fact it's simply the tutorial proposed

### Maximum Ponded Depth

Hello sir!

In a status report the Volume of flooding in a node and the Maximum Ponded Depth can be seen. From the computed Volume of flooding, how does SWMM compute for the Maximum Ponded Depth?

assuming:

depth = Volume / Area, what area is being consi

### Simulating Leaf Gates

I am trying to determine the best way to represent "leaf" gates in SWMM5.  The gate consists of two panels that overlap each other.  The top gate serves as an overflow weir and drops as the upstream water level rises.  If the top gate is fully lowere
