Purpose of this project is regulation of the Janja riverbed in Janja, including protection of the mountain and inland water of Novo Naselje Janja, in total legth of 3.94 km (from the bridge to settlement Janja and upstream from the mouth of the creek Janjica).
Besides the regulation of the Janja riverbed, a subject of this project was the edge canal „Obrijez“, from the mouth od creek Janjica upstream, over a lenght of 2.49 km. The works were related to the excavation of a new canal with coating on the inflow of the canal into the Janja riverbed. This project built a stable riverbed of the Janja River, with the flow cross section formed in such a way as to ensure safe carrying of high water at a level occurring once in a hundred years p=1/100, and also to protect this part of riverbed from further erosion and destabilisation.
The selected solution for the protection against external waters is a passive type of protection against external surface water, which is purely defensive in character and consists of the regulation of the minor riverbed, construction of protective defence embankments, expansion and deepening of the main riverbed including intensive maintenance. This type of protection is a common way of regulation, and it has been proposed to regulate the water flow regime and to prevent eroding banks of the Janja River in this area.
Besides the above mentioned, an additional goal of this project is to secure continuous water drainage from „Novo Naselje Janja“.
