Abstract:
With urban developments and the aging of urban water distribution pipes their demand for repair and maintenance is rapidly grown. There are several factors that affect the performance and leakage in water and wastewater distribution networks (Ameyaw and Chan, 2016). By increasing the water leakage from pipes and wastewater depletion from houses to the injection wells, water level under the city ground is rising and saturation condition will be created near the underground infrastructures.
In recent years, local uplifting of subsurface water level in metropolises created different challenges over water and wastewater systems with multiple damage effects (Baah et al., 2015;Qiu et al., 2016).İn recent two decades, the rising of groundwater table in Kerman city have caused several challanges over the water and wasetwaer infrustructures. İn the ancint zone of the Kerman city, water level come up to 3 meter under the groundsurface and is interacted with several underground structures and basment flooding. The rising water table have several destructive effects over the urban infrastructures. The main purpose of the present study is to investigate the effects of rising subsurface water level in Kerman city by using an AHP based damage prioritization to depict the relative importance or urgency of a damages of water level rising over infrastructures.
