Hi all. So I am looking at buying a 6-acre pond that is classified as Low Hazard damn by the state. They are planning to re-assess hazards this coming year and I may pass on it if its obviously going to be put into a higher category. I know there was a house built downstream after it was first rated.
Is there simple damn-break inundation model or approach to estimate flood hazard on dam break based on 1 or 2ft topo maps, height of dam, and volume? its an 8 foot dam, 17 acre-ft storage I think. I realize that an engineering firm would do this, but im looking back of the envelop at this stage. I attached a topo map with 2ft lines- do those houses look obviously at risk? Yes, I know no one can know for sure... no one is getting sued. Just looking for opinions.
In the map, the front parcel with the outflow is 10 acres.
