Surface and ground waters are one of the basic resources; they are an important constituents of the environment and serve to satisfy economic and other needs of the society. The purpose of the actually prepared modification of the Czech Water Act (Law No. 1381973) discussed in this paper is (1) to protect water in a comprehensive and flexible manner, considering its irreplaceability and society-wide significance, (2) to regulate its withdrawals and other treatment in a planned manner in order to maintain a balance between the demand for water and the capacity of water resources, (3) to care for its purity and economic utilisation, (4) to protect against floods, and at the same time, to respect the conservation of nature and ecosystem protection, and (5) to provide for recreation, shipping and other important water uses which are of interest to the society. The paper is presented to serve as a basis for the planned comparisons of the legislational state-of-the-art in the USA and Czech Republic.

The political difficulties in reaching agreement on water quality management between the very different interests of upstream and downstream riparian countries are stressed. The author nevertheless considers it inevitable that there will be a trend towards such agreements, albeit gradually and not necessarily in a systematic manner. Problems in relation to transboundary water quality are multiplying as pressures on limited water resources increase. Micro-pollutants in water, sediments and biota are of particular significance. Sporadic pollution causes special difficulties. There are growing sensitivities about developments located close to frontiers which pose potential threats to water quality in the downstream country. Efforts to secure rational systems for surveillance and control of transboundary water pollution are summarized and general principles proposed which could be utilized in a step by step approach towards comprehensive water quality management within international river basins.

Prior to the last decade, federal water-project construction programs dominated water policy. These programs continue, but at a reduced level of funding, and the nation now is denning a new agenda of water resources issues to include water quality management and water allocation. Economists engaged in studies of water resources policy, and who seek to influence the direction of policy through research, teaching, and extension will find these exciting times.

ABSTRACT The implementation of National Water Resources Policy instruments depends on detailed information in space and time, on a large scale, within the river basin. This research aims to evaluate scenarios to support water quality management in watershed by modelling with spatio-temporal discretization distributed in a small spatial dimension. The SWAT hydrological model was applied in the Itajai river basin. This hydrographic basin with 15,000 km2 was discretized in 2,103 hydrological response units (HRUs). The model input data for each HRU were fed in, from the quantitative and qualitative aspects. The time series of water quality was obtained in non-systematic monitoring from different sources, such as water supply companies and potential polluting companies, among others. The model calibration and validation were performed, presenting adequate results for both the quantitative and qualitative processes. The scenarios corresponding to current and evolutionary situations of pollutant contribution for four water quality parameters (biochemical oxygen demand, total phosphorus, total nitrogen and thermotolerant coliforms) were analysed. The results are expressed as the mean, median, non-exponential frequency of 80% and reference flow, discussing the statistical index that best represents the pollutant concentrations in the bodies of water. The simulations show that the measures proposed for the water quality management of the basin promote a significant reduction in pollutant concentrations in comparison to the critical scenario. According to the results, it can be affirmed that the discretization of the basin in small contribution areas generates greater results precision of the model. The daily and distributed data in the basin provide localized information, according to the basin ortho coding, supporting the decision in order to support the management of water resources, contributing to the implementation process of the framework of surface water courses in the basin, as well as serving as a generic model for other purposes.
