Short summary
We present a new method that incorporates flood-envelope-curve methods, radar-derived precipitation data, and flow-routing algorithms to calculate frequency-magnitude-area curves (FMAC). Our results show that flood discharges increase as a power-law function for small contributing areas, but start to increase more slowly at higher contributing areas. We find that our FMACs have similar and/or higher flood discharges than published flood-envelope curves for the same areas.
