DESIGN OF THE RETENTION BASIN

Radom su opisani poznati problemi s kojim se susreću dotrajali klasični sustavi odvodnje oborinskih voda u urbaniziranim sredinama. Površinsko otjecanje oborinskih voda i voda nastalih otapanjem snijega i leda je od davnog vremena predstavljalo veliki problem, a rješavanje istog još veći izazov. Stoga je bilo potrebno pronaći novi pristup projektiranju sustava odvodnje. Tako je nastao integralni pristup koji nastoji da nadzemni dio odvodnje obavlja svoju ulogu u većoj mjeri nego podzemni dio. U interesu je projektirati tijek odvodnje na način da bude što sličniji prirodnom procesu otjecanja i toku vode. U radu je objašnjen navedeni pristup s posebnim naglaskom na retencije te je kao primjer izdimenzionirana jedna retencija.This paper desrcibes common problems which are brought by use of the outdated types of stormwater management systems. Since the ancient times the urface runoff of rainfall and waters made by the meltdown of the snow and ice were a big problem to deal with, and solving them even bigger challenge. Therefore, it was necessary to find a new approach to planning and designing of stormwater management systems. So the new solution was born, the integrated approach that strives to get the above-ground parts of the stormwater management system do most of the work. The main goal is to design a flow of the water that is very similar to the one we can found in the nature. The above-mentioned approach is described in this paper with a special emphasis on retentions and as an example, a calculation of desin is given in the end
