flood resistant design and construction in seismic zone

As we know, iran has high seismicity due to its location in the alpine-himalayan (alpide) fault path. of course, as we know, mountains are the result of millions of years of tectonic plates created by the pressure of these plates. on the other hand, the thalweg between the mountains cause rainwater to accumulate and thereby create larger currents of water,eventually creating much larger volumes and flooding. thus cities that are on the slopes or near the mountains are in addition to higher seismic hazards such as floods. also in several cities of iran such as northern and western cities, due to coexistence of alborz and zagros mountains and caspian sea, and also the places that are near the river and coastal places, there is high risk of earthquake and floodhazards. especially the destructive effects of recent iran’s floods (like the following images) on structures have caused more attention by designers to the impact of flooding on designs. another important issue is the locating. a suitable locating means that in addition to choosing the correct place for construction, soil type is also important. as well as being important for building, to reduce the impact of an earthquake, thisis also important for flooding and should be considered. as important as the direct construction of the building is to reduce the impact of the earthquake, this is also important for flooding and should be considered.
