Természetharmonikus és integrált vízrendezés 261 regulation. Water regulation activities became ever more harmonized with the requirements of nature conservation and environmental protection, integrating into the activities of the latter too. Integrated water regulation cannot follow a predetermined scheme but must be tailored to the individual character of the given environment. The individual solutions are those "best" water regulation practices which integrate those technical, economic, biological and environmental protection measures that allow the most efficient management of renewable natural resources. Main elements of this system are as follows: — best available landuse and landscape management practices; — nature-friendly water regulation practices: — nature conservation and environmental protection measures; — water regulation works fitting into the landscape; — biotechnical measures; — biological drainage; — nature-friendly agrotechnical practices: — crop cultivation and — live stock breading — alleviation of harmful effects, optimization of impacts: — limitation of dimensions; — protection of waters against pollution; — use of complex, closed water management systems. One of the best ways of planning water regulation works which would fit into the environment is provided by the environmental impact assessment (EI A). Table I. gives a list of EI A methods which are being used in the practice, to certain extent, for assessing the impacts of hydraulic engineering structures. As contrasted to this Table II. provides a list of EIA techniques which are being used for assessing the impacts of engineering activities in an indirect, auxiliary of formal way only. It is generally believed that a preliminary of simplified impact assessment be carried out for all activities which have impact on the environment, disregarding whether the making of an EIA is compulsory or not for the given case. Such a preliminary assessment could, for the majority of cases, be made with little additional cost as part of the planning or design activity. In the case of existing engineering establishments the methods of impact assessment have two basic forms: Environmental auditing , that will be demanded by the environmental inspectorate when environmental damage or risk has been perceived. — Environmental performance survey, which can be carried out by the party in concern for assessing its own environmental performance and may request the environmental inspectorate to approve it. In assessing the impact of water regulation activities quantitative modeling, that is the making of water budgets, is the feasible means, along with trend extrapolation, making of check-list and applying the method of interactive matrices. * * * Naturnahe und integrierte Gewässerregulierung von Dr.-Ing. László MADARASSY Die Auswirkung der Arbeiten für Gewässerregulierung auf die natürliche Umwelt ist wegen dem großen flächenmäigen Umfang dieser Arbeiten bedeutend. Sie verändern nämlich das Anslitz der Landschaft und ermöglichen eine weit intensivere Nutzung des Einzugsgebietes, als zuvor. Die
