Roads influence the hydrologic response of a watershed as they affect the water regime.This is important especially during extreme precipitation events in critical spots of roads and watersheds.This study suggests a method to analyze watershed characteristics and road descriptors, so-called PhysicalCatchment Descriptors (PCDs), for prediction of flood risk along roads. The method was developed andtested in a Geographical Information System using topographical, geological and road data from an areain W Sweden having experienced severe road flooding during an intensive rain event.The results show that there are two categories of intrinsic descriptors which are useful for prediction of criticalspots prone to flooding along roads in a watershed: (a) watershed-related descriptors and (b) road-relateddescriptors. Analysis of superimposed combinations of these two categories of descriptors can be used foridentification and pre-evaluation of critical spots with high risk of flooding in watersheds containing roads.
