The regulation of the rivers Dyje and Morava was a radical intervention to the development of the landscape of meads. In regulation of riverways the rivers have been straightened, dammed, permanent floods ceased and in meads the level of underground water decreased. Non–regulated flows have been conserved only in short dissections. A part of water management treatment was the building of the waterwork Nové Mlýny on the river Dyje – it contrains three reservoirs overflowing the most valuable meadow ecosystems. The present situation needs a quick solution. This was the reason that at the end of 1991 was set the project „Evaluation of selected variant of solution of clash of interests in the area of the waterwork Nové Mlýny“. The study has three stages. From methodological viewpoint is important especially the IInd stage containing the prognoses of solution. It sets out from the analysis of the functions the landscape has to fulfil (inevitable functions) or may (improving functions). For all these functions are characteristic certain levels of the storage task of single reservoirs at which the functions change (fault level) and similarly certain periods when the equipment conditioning their existence expires, resp. is necessary to be reneved (fault period). Evolutional time-spatial solution is presented in the study by 47 steps (each is reversed in 16 ways enabling in time react also to unforeseeable changes of functional claims of the whole landscape complex. The aim of multicriterial evaluation was to confirm the whole landscape complex. The aim of multicriterial evaluation was to confirm the correctness of presumptions the IInd stage is originated from, to verify the possibility of realization the 1st step common for all ways, resp. variants of solution and on the basis of fulfilment of single functions to choose the ways seem to be the most advantageous.
