Abstract

The AA. analyze, using GIS, the relationship between short-term lateral and vertical morphological adjustments observed over the Subcarpathian Prahova River and specific long-term evolutionary patterns. Human disturbances and hydrodynamic characteristics during high intensity flood periods are assessed in the context of existing neotectonics and lithology controls on channel and valley morphology. Surveyed cross-section profiles were used to construct the geometry of a 1D hydraulic model. Simulations were performed using the HEC-RAS software (USACE) under steady flow conditions for flow values between bankfull and the peak discharge value of typical flood events with a return period of 20 and 50 years. Three main areas with high values of computed shear stresses and velocities and corresponding low values of width to depth ratio (W/D) were identified. The evolutional patterns of Prahova River channel are tectonic-structurally determined, developed and maintained during the Quaternary mainly by the principles of river morphodynamics. In a long-term perspective, the overall channel evolution of this river is expected to be strongly influenced by human activity
