—Czechoslovakian frontier). This can be credited to the Hungarian project discussed, as a practical utilization of results and experiences of the project achieved thus far ; — two AWQMS-stations are being installed on the Danube river (cross-sections Rajka and Szob) ; these stations will form in the future part of an integrated information system on water quality data collection along the Hungarian Danube, — the field investigations on the Sajó River into bioresistant substances (for establishing the limit values for water quality) have been completed, — the checking of sensitivity and verification of the Sajó water quality mathematical model have been accomplished, — the Regional Economic Model of the Sajó River has been developed, — the first, two-dimensional mixing model over the Danube reach Szob—Budapest has been formulated, it is being refined, — an international seminar on Systems Analysis in Water Quality Management was held between 2—8 February, 1975 in Budapest, convened by the World Health Organization in collaboration with the Government of Hungary within the context of the project. During the Seminar 10 foreign and 5 Hungarian papers were presented on experiences gained with different types of models, as well as the survey of the trends and state-of-the-art of systems analysis and mathematical modelling for water quality management around the world were discussed. The Seminar was attended, besides a group of Hungarian specialists, also by experts from 14 other countries, representing, inter alia the Danube River riparian countries, further by the representative of 7 international organizations, — it should be underlined that the first ProjectIntroductory Seminar on Water Quality Management was held in Budapest from 8 to 12 May 1972. During the seminar, organized by the Hungarian authorities in collaboration with WHO, the technical, hygienic, economic, administrative and legal aspects of water quality management were discussed. More than ninety Hungarian specialists attended the seminar, together with 20 specialists from Bulgaria, Czechoslovakia and Yugoslavia. For this Seminar, which was understood as a formal opening of project activities under the HUN/ PIP001 project, lectures were delivered by the foreign and two Hungarian specialists, — as to the use of the UNDP/WHO inputs (up to now, i. e. end of 1975), the following has been accomplished, or allocated

: (a

) fellowship (study tours): in the period 1972— 1975 117 Hungarian specialists of several professional branches went abroad, for studying the various aspects of recent research and development in water quality management; moreover other 17 Hungarian specialists have already been awarded foreign fellowships — they start their studies abroad early in 1976 ; (b) consultants (experts): 41 visits of foreign con. sultants and experts were made to the Projectsite, to advise and to provide „know-how", or to consult with other counterpart specialists, on the different subject areas of the projects ; a panel of experts is being convened in June 1976 to assess and to evaluate the project fidings and recommendations at project termination ; the project was visited by several UNDP/WHO officials for reviewing the implementation and execution of the project ; (c) equipment: was provided for project works and activities in a value of round 350 000 US $ ; this included, inter alia, spectrophotometers, Atom Absorption Spectrophotometer, TODAnalyzer, Beckman M. 915 TOC Analyzer, Gas Chromatographs, Technicon Autoanalyzer TT, TOC

—UNOR — measuring apparatus, Technicon IV Autoanalyzer, VIS

—UV Chromatogram Analyzer, Nuclear Magnetic Resonance Spectrometer, Hydrolab Surveyor System and others. Prospects of Achieving Project Objectives The Project has made substantia] progress toward achieving the objectives. Changes in the existing PERT-Monitoring Network for some project activities have been agreed to and were introduced. These changes are aimed at integrating all the modelling efforts, to ensure the consistency of inputs and to enable that modifications be made efficiently. It appears now that the primary objective of the project related to activities in the Pilot Zone I (Sajó), namely the preparation of the integrated engineering-economic water quality management model and of the optimum investment plan for the Sajó river, for use by National and Regional authorities, will be achieved. That investment "model" will be accomplished as a regional water quality management model (RWQM), comprising a set of submodels, such as the activity models, the environmental models, and the computational algorithm. The review of activities in Pilot Zone II (Danube ) made during the Mid-Project Evaluation led to a reformulation of goals to be reached under the existing project in that Pilot Zone. The present objective of the programme of the project along the joint Hungarian

—Czechoslovak reach of the Danube River is to characterize water quality in the complex, hydraulic system and to identify the most important materials affecting water quality from the Hungarian standpoint. (This includes, for example, the problem of sampling micropollutants and toxic materials.) The objective at this time is not to develop a "Formal" water quality model of the reach of this watercourse. Because no formal water quality model will be developed for this Upper-Danube pilot zone, the formulation of an optimal scheme for water quality management in the region in a fashion similar to the river Sajó catchment is not possible. Therefore, only the least cost alternative for meeting the discharge standards specified will be determined for each of the major dischargers over the Hungarian reach of the Danube. The approach mentioned above to the UpperDanube stretch reflects the apparent presence of several limiting factors in this pilot zone, which are no more likely to appear in the foreseeable future once international co-operation on this international river will be realized. This statement reflects also an appreciation of the necessity of developing an action programme concerning water quality of the Danube as agreed upon during a Workshop on the Studies and Assessment of Water Quality in the Danube, which was convened by the WHO Regional Office in Copenhagen, between 3 and 7 March, 1975, with the participation of the majority of the Danube ri-
