POSSIBILITIES OF SOFTWARE EVALUATION FOR THE RIVER COURSE MODIFICATION. CASE STUDY: SIRET RIVER IN BACAU REGION SECTOR

The main purpose of this article is to introduce a method helping us to understand the evolution and changes that occur on a river route. Route transformations on a river flow are usually highlighted by maps or ortophotoplans. However, these are made at a certain time slot and thus they cannot reveal the factors affecting the river route. Therefore, in this article, based on three Siret river routes performed in 3 different time slots, 1954, 1980 and 2010 respectively, was intended to highlight the distribution mode of the flow velocity by using the Ansys-Fluent simulation software. Following the simulation, a series of helpful information revealed the concerned erosion areas, making thus possible the future assessment of the Siret river.
