Spatial planning is one of the non-structural flood protection measures. High water events and the accompanying erosion are natural phenomena, which in the context of spatial planning represent a restriction when it comes to land use. Land use together with water flow properties influences the shear stresses that occur when water flows through floodplain areas during the high water events. Erosion occurs when the value of the shear stresses exceed limits of the shear resistance. Erosion hazards near buildings, where higher water flow velocity could occur, were not dealt with. Planning of the use of the riparian space has to be thought-out and in accordance with the applicable regulations. The key is to choose uses, which are more resistant to water erosion. Hydraulic roughness depends on land use and by changing the land use, we can influence water retention, reduce the speed of the water flow, the local depth, and extent of the flood prone areas. By recording exceeded shear loads, the cause and effect links between land use and high water processes have shown. The selection and change of land use are classified as sustainable measures because, in addition to the hydraulic function, they also include an environmental function. Consideration of the environmental aspect in the process of spatial planning follows the objectives of sustainable spatial development. In accordance with this and the applicable regulations, this master's thesis presents the proposals for scenarios with sustainable measures. A comprehensive arrangement of the riparian area is envisaged in the scenarios, which, in addition to ensuring better resilence, includes the area in the system of green areas of Šoštanj.
