• [x] #69
• [x] #70
• [x] compute betweenness centrality value using street length as weight --> did not work well, there is no distinct pattern
• [ ] #82
• [ ] Assign size and slope for compute discharge capacity
• [ ] compute the corrected betweenness centrality by incorporating auxiliary data
• [ ] estimating final network topology by removing insignificant edges.

Discussion with Helene:

• [ ] consider road sizes?
• [x] consider drainage locations to open water --> already setup channels
• [ ] wasterwater treatment plant info?

The static head loss is the amount of energy needed to lift water, calculated as the hydraulic head difference between upstream and downstream levels, with the consideration of water level boundary conditions at outfalls (as illustrated in Figure [2] But then because we don't have the invert levels, 1) will be None --> nothing to do about that. we only have 2). also becasue we dont know the size of the pipe, we cannot derive dynamic headloss. --> maybe by assuming a velocity, we can get a roughness estimate of the cost.

maybe it make sense to use hydraulic gradient, e,g. elevation differences devided by length. as an addition to the default min length method.
