Hi,
I am Civil engineer by profession and I have 5+ years of experience in water resource engineering field. I worked on many flood risk assessment projects for UK, US, Australia and middle east regions.
I checked study area and found that Lewis Creek passes near this area, the contributing catchment size at this location is roughly 625 square kilometer. This study might need both hydrology and hydraulic analysis.
I am proficient with the flood modeling software's required for US regions and mapping packages as well. I have resources as well to support on this work, I feel I can help you with this flood impact assessment work.
Please let me know if you are interested, we can discuss more in details.
Kind Regards
