The role of climate and hydrological elements in the production and persistence of excess water in the Plain of Someș

Abstract

In determining water excess in the Plain of Somes, we analysed the triggering factors which are directly involved in the formation of the risk phenomenon and which are considered to be the dynamic factors. Of major importance in deciphering the causality of the water surplus are the triggering elements, especially the climatic ones (the rainfall regime), and depending on them to a great extent - the hydrological ones (water resources, drainage). It can be argued that in the last decade, the biggest problems were created especially by small basins and small watercourses, which due to the changes in the precipitation regime (large intensities on small surfaces) had caused many floods, destruction of human settlements, roads and bridges, and had favored the triggering of landslides and implicitly the excess of soil water. The analysis of the natural hazards, implicitly of the water excess, was primarily aimed at meeting the requirements of the elaboration of the landscaping and urbanization plans of the Plain of Someş, according to the legislation and norms in force.
