The influence of hidroclimatic risk factors on the evolution of natural sites

Abstract

The paper presents an analysis of hydrological risk parameters and record linkage on the river Moldova in the area of Soci, Iaşi County. This area is framed in a natural site “Oniceni – Miteşti” which is situated on the river Moldova. The site is part of the natural “Oniceni – Miteşti” integrated European Ecological Network Natura 2000 site in Romanian. Natural protected area of the site was affected by multiple floods in recent years. Floods have changed morphologically and major minor riverbed of the River and this situation has influenced the evolution of parameters and safety. The study focused on the analysis of fluid flow (minimum, medium and maximum) and solid measured over a period of 50 years in the area of research. Processing of data showed more flood flows during that year (e.g., 2004, 2006 and 2008). The positioning of the river within the site's natural "Oniceni-Miteşti" imposes special conditions on the design of hydrotechnic constructions.
