22 Hidrológiai Közlöny 1977. 1. sz. Principal objectives of research activities carried out under the Project. Perspectives of practical applications of the results By Dr. P. BENEDEK — GY. PINTÉR 1. Methodological and practical objectives oi the Project The fundamental objective of the UNDP/WHO Project HUN/P1P001 "Water quality management pilot zones" was to develop the advanced methods of complex water quality management activities for regions, viz., extending to catchment area units,and to apply these in pilot areas. Differences in the particulars of the two pilot zones selected for purposes of the Project have affected appreciably the main objectives and scheduled programme of the water quality management studies related to the individual pilot zones. The Pilot Zone No. 1 (the Sajó Region) is round 4200 km

2 large and comprises the entire Hungarian catchment of the Sajó River. Pilot Zone No. 2 (the Upper Danube Region), on the other hand, comprises the direct Hungarian catchment pertaining to the Danube section between Rajka and Budapest and covers an area of round 6000 km

2. In Pilot Zone No. 2 the factors limiting the development of a data base essential for formulating a comprehensive water quality management programme (e.g.the lack of detailed background data) were appreciably more pronounced and accordingly the objectives of the works to be performed here under the Project were also more restricted. The ultimate goal of the water quality management programme in the Sajó Region is the development of an optimized plan of action schedule, which —taking into consideration the perspective development up to 1985—presents for attaining specific wa-. ter quality standards in the Sajó River coordinated recommendations concerning the sequence of pollution control measures in the region, improving thus the anticipated economic efficiency thereof. The formulation of an optimized plan of actions is made possible by the regional engineering-economic model of water quality management permitting the determination of the optimum engineeringeconomic solutions of the measures (pollution control investments) needed in the system. In the case of the Upper-Danube Region the objective of the programme is the development of a descriptive water quality model for the Hungarian section of the stream, further the compilation of a recommended schedule

—based on regional studies

—aimed at the minimization of indigenous polluting effects. The main objectives identified at the outset of the programme in the "Project Document" have been formulated more specifically and refined with the cooperation of WHO experts as work has reached more advanced stages. These modificaResearch Centre for Water Resources Development (VITUKI) Budapest, Hungary. tions have been approved of by the positive "MidProject Evaluation", the assessment at mid-time performed by the UNDP/WHO. Of these mention must be made of the extension of the Pilot Zone No. 2 to the direct catchment of the Hungarian Danube section upstream of Budapest, further of the decision according to which the COD water quality model has been adopted as the basis of further water quality management model studies in the Sajó Region. The Project activities have been performed in 5 principal groups of subjects. Of these groups special mention should be made of some part-objectives of major importance to be mentioned subsequently, the majority of which has already been realized as the work approached its terminal stages: I. The acquisition and evaluation of basic data. Computerized data processing and storage — establishment of a data collection system meeting the demands for data in water quality management problems, — introduction of advanced methods for the processing and storage of data, — construction of automatic water quality monitoring stations. II. Studies on bioresistant substances — development and introduction of the methods of special analytical procedures, — analyses on organic- and inorganic micropollutants, as well as on bottom sediments, — determination of limit concentrations. III. Studies on the assimilation and allowable load conditions in the recipients. Development of the water quality model — development and testing for sensitivity of the single-parameter (COD) model of water quality for the Sajó River, — formulation of the descriptive water quality (dispersion) model for the Szob

—Budapest section of the Danube. IV. Studies into waste water treatment technologies — development of alternative treatment methods for the major domestic- and industrial effluent dischargers in the Sajó Region, — the construction of pilot-scale experimental waste water treatment facilities. V. Studies into economic- and legal problems optimization model — formulation of the engineering-economic model of water quality management for the Sajó River,
