The diploma thesis is divided into three large parts and presents conceptual project. In the first part are carried out and presented hydraulic analyses of the Savinja river through Laško for different conditions. On the basis of hydraulic analyses we have seen, whether certain interventions on the riverbed, and the construction of a dry pond networks in the Lower Savinja valley are rational. Based on the hydraulic analyses in the second part of thesis we focus on finding areas where river Savinja overflows its banks. Also in this part of a thesis we determine the required height and length of the individual sections of flood walls. In the last part we tried to find the proper execution of these flood walls. Classic execution of concrete walls would change the quality of life in the centre of Laško a lot. IBS flood protection system presents an alternative to the classic execution of flood walls, but the price is up to three times higher, at the same time with this flood protection system the centre of Laško is protected from floods, just as well as the quality of life for residents does not change.
