Capturing the maximum depths occured in SWMM by pyswmm, capturing surcharge

[csofios18]

I am currently trying to get exactly the maximum depths of the node summary results of SWMM in my pyswmm code. Some of my nodes have surcharge and their maximum depth is higher than their full depth. How i can capture that in my pyswmm. I am currently expressing this for my nodes as "node.head-node.invert_elevation" instead of node.depth but i get no different results!

@csofios18 if you only need the maximum depths after running a simulation, you can use swmmio:

import swmmio

# create a model object 
model = swmmio.Model('path-to-model.inp')

# if you have your rpt file stored in the same place as your model, you can get the Node Depth Summary like this
model.rpt.node_depth_summary

Name	Type_Node_Depth_Summary	AvgDepth	MaxNodeDepth	MaxHGL	MaxDay_Node_Depth_Summary	MaxHr_Node_Depth_Summary	MaxNodeDepthReported
J3	JUNCTION	0.96	1.64	8.19	0	10:00	nan
1	JUNCTION	0.07	0.94	17.94	0	10:00	nan
2	JUNCTION	0	0	17	0	00:00	nan
3	JUNCTION	0	0.39	16.89	0	10:03	nan

If you want the each node's max depth, invert elevation etc. joined in one dataframe with the simulated results, you can do this:

from swmmio import Nodes

nodes = Nodes(
    model=model, 
    inp_sections=['junctions'], 
    rpt_sections=['Node Depth Summary'], 
    columns=['Name', 'InvertElev', 'MaxDepth', 'MaxNodeDepth', 'MaxHGL']
)

nodes.dataframe

Name	InvertElev	MaxDepth	MaxNodeDepth	MaxHGL
J3	6.547	15	1.64	8.19
1	17	0	0.94	17.94
2	17	0	0	17
3	16.5	0	0.39	16.89

Thanks! But this requires the simulation to be done in SWMM so we have the reported results! What if we want to generate the simulation in python as well!

@csofios18 I think @aerispaha showed you how to use swmmio to open the RPT file. That file can be generate from both the UI and PySWMM. PySWMM is SWMM but with a nice programmers interace.

@csofios18, if you want to do this with pyswmm, directly, use node.statistics. This returns a dictionary of all values:

Here is an example bundle with the Max Depth:
