Categories of hydric significance are known from excellent, through good, average up to limited and they express spatially the possibility of the landscape in relation to water retention. In areas of low hydric significance, we can propose the properly land use, which was applied at the local level. Ľubica river basin, often threatened by floods, is in third category - average hydric significance. Based on four scenarios of land use (change of permanent grassland to forest, the change of arable land to forest, the change of arable land to permanent grassland and change of arable land to non-forest woody vegetation) we have submitted concrete proposals in the model area. Optimal space utilization of river basin is the base of knowledge and its characteristics, aim to the ecologisation of the environment and it´s the prevention from floods.
