THE PRESENT STATE OF DENUDATIONAL GEOMORPHIC PROCESSES ON THE LEFT BANK OF IZVORU MUNTELUI -BICAZ RESERVOIR (POIANA LARGULUI - BUHALNIŢA SECTOR)
Journal Title: Present Environment and Sustainable Development - Year 2013, Vol 7, Issue 2
Abstract
The knowledge of present denudational processes from the left bank of Bistriţa valley in the area between Poiana Largului and Buhalniţa – Rugineşti is of major importance at least from two points of view. The first refers to the relations between the evolution of denundational processes and of the lake area (implying clogging processes). The second relates to the proportion in which the respective slope processes affect the quality and functionality of DN15 national road, important route that links Piatra Neamţ with Vatra Dornei and Transilvania. This study analyzes the present state in the evolution of denudational processes and the way in which they negatively affect the functioning of DN15. The study has been eased by the existence of several studies from 1960-1980. Our research from 2011-2013 has focused on evidencing new causes that favor the extension and reactivation of landslides. Among these are the numerous constructions located on relatively stable slope deposits, missing corresponding landslide prevention and mitigation works, as well as the heavy traffic on DN15 from the last two decades. The study also had in view the identification of areas with recent landslides which have lead to the impairment in different aspects of the DN15 carriageway and the temporary closure of several sectors.
