Lastly, I changed the design of the weir tanks to be extensions of the channels instead of boxes at the end of channels. I encountered a problem with the inlet channel side and plan to fix it next semester if I am unable to finish it this summer.

I am working on creating an automated design of the drain channel for the online design tool. Nanditha and I have contact the engineers in Honduras for their input in the design. They helped us determine the positioning of the channel which is crucial to the coding. We have also met with Monroe to determine design assumptions and constraints that must be considered while designing the channel. I also wrote and iterative code that finds the optimal head loss from which the geometry will be determined.
We then coded the channel by creating two cross sections, one and the beginning of the flocculator and one and the end of the sedimentation tank, and lofting them together. May helped create a Loft function in the MtoAtranslators page which allowed us to do this. The channel is now drawn completely with the correct slope derived from the headloss. The channel was designed with a conservative approach in mind, so future changes could optimize the volume to its absolute minimum. Finally, I documentated the code files, transferred them over to the source file. Testing is the next step.
