Abstract:

River lateral dynamics and floods in relation to human communities. Case study: Moara Domneasc Village (on Lower Teleajen River). One of the challenges set at the beginning of the 21st century is living with floods and natural dynamics of rivers. In this general framework, the main goal of our paper is to elaborate a diagnosis regarding lateral migrations and floods of Teleajen River in the proximity of Moara Domneasc Village (Rafov Commune, County of Prahova). Our analysis includes two approaches: a hydrological and a geomorphological one. The hydrological approach aims at analysing maximum discharges variability of Teleajen River at Moara Domneasc gauging station and at showing its floods’ frequency. The geomorphological approach leads to outlining the wandering area of Teleajen River based on a diachronic cartography, which takes into account documents covering the last 150 years; the boundaries correspond to the maximum extension of its channel and abandoned channels. The area overflowed in September 2005 is assessed based on drawings from the urban plans of Rafov Commune. The outcome shows that the area appropriated by Teleajen River was partially exploited by society. Therefore the village of Moara Domneasc is exposed to these hazards.
