Floods cause significant damages not only on, but also beneath the earth’s surface. Infiltration of surface water into deeper soil, flooding of the urban sewer system and, in consequence, rising groundwater levels are main causes of subsurface damages. Nevertheless risk assessments for rising groundwater are levels essential for subterranean infrastructure and buildings. The results show that the surface flooding has the dominant effect on the flood damages in the case study region (Shiraz). Furthermore it has been indicated that one or tow months after the flood happened the groundwater in various regions of shiraz urban even though 5000m far from the river borders reached their maximum level.
