Flooding of road networks occur when the road networks which are normally dry are inundated usually after rainfall. Buildings are sited on water causes which reduce buffer zones meant for free flow of water and in some cases, the blocking of flow of water passage entirely leading to the flooding of communities and road networks upstream of the restricted sections of the catchment areas. Culverts and other drainage structures that are constructed on roads for safe channeling of water at stream/ water crossings are often found to be the bottleneck, limiting flow and contributing to flooding and washout of road pavements.
