The master's thesis deals with the subject of impacts on water and waterside rural space by different activities present in the landscape. Agriculture, water planning, divestment of water and mineral materials, settling by infrastructure, recreational and tourist activity as well as other human activities influence the present and the future conditions of the water(side) space. It is for this reason essential to define a balanced relationship between its development or use and its protection. The thesis describes water management in the past periods and presents a summary of legislation from this area. Due to more intensive development in other European countries the water(side) space used to be subjected to more severe changes than in Slovenia. However, the situation has changed. In the wider European area has highlighted the importance of sustainable water management and restoration of natural conditions as possible. Based on the analysis of individual sectors and their impacts on water(side) space the thesis shows orientations with the aim of sustainable preservation of natural or ecological landscape elements. It proposes measures or guidelines for sustainable development of waters in rural space, as Slovenian waters are still not maintained adequately and are not regulated according to the principle of sustainable management. In some areas the development of landscape still lacks any plans, which also has consequences on the water(side) space. Sustainable water management is according to legislation part of the integral planning of rural space, but the problem of its realisation or implementation in reality remains unsolved. The thesis also brings attention to increasing influence of climatic changes on the condition of waters and gives the basic guidelines for their development in the future.
