Hidrológiai Közlöny 1974. 3—4. sz. 154 D. Quinco (OVH) At the Water Management Department of the National Water Authority efforts are undertaken to ensure increasingly the time necessary for designing as the prerequisite for the elaboration of alternative solutions. The Department is fully aware of this resto provide optimum occupation for the designers. The flow of information in engineering designing must be organized to a higher extent, in the interest of making the advances in designing, research and development work accessible for general application. It is emphasized that engineering design plays a dominant role in the realisation of projects. For this reason it should be appreciated that the use of results of technical development and engineering regulations should be deliberate and intensive in designing work. Deliberate and systematical procedure can be ensured by identifying definitely in the production process of designing the point where technical development and engineering regulation can be adjusted to the actual requirements of engineering designing but the use and application of results is impossible unless the designers are kept informed about these. For this purpose the engineering council at the designing enterprises appears to afford the proper opportunity, before which the designer could state on which of the available technical development and regulatory publications he has made reliance, as well those which he was unable to use although they were related to the problem. The council could thus exert direct control over development and regulation activities to serve the demands of engineering designing. J. Kohut (VIZITERV) Supplementary remarks are made in connection with the role of engineering regulation in the designing of water projects. Special mention was made of the standard specifications to be considered of paramount importance for engineering regulation in the water sector. J. Fekete (OVH) Commented on the paper by Gy. Varga, by stating that a fundamental requirement in the development of water management is the improvement of engineering designing work. There are two approaches to this problem, namely — development of the designing process, and — perfection of the contents of the project documents. High-level designing, advanced soil mechanical and geodetical surveying, the elaboration and analysis of alternatives, as well as the aoplication of computerized methods are all essential to the economical designing of projects. In this respect attention is called to the possibilities in aerial fotogrammetrv and to the necessity to perfect geotechnical and geodetical surveys. In this connection the effect of economic incentives on the imnrovement of designing activities would be worth considering. Dr. K. Ziegler (VIZITERV) Reflected on the mechanical-electrical engineering aspects of designing work. This special field plays an increasingly important role in the designing of complex projects. The conventional approach of hydraulic engineers to the technological process is no more adequate in the designing of water projects. The high value of mechanical equipment and the multitude of types available on the market necessitate consultations with the mechanical engineers in early stages of designing already. In some cases mechanical engineers are even better qualified to assume the responsibilities of the general designer, iust as in the case of industrial projects. In projects involving process control and automated equipment the electrical engineers become the principal partners of the hydraulic engineers formulating the general concept. It is suggested, that the mechanical-electrical engineering sections at the designing enterprises undertake construction development activities for the manufacturing industry. An additional benefit of this activity would be that the designers of mechanical equipment would supervise and follow the manufacturing process. Moreover the designer would gain in time and in experience in the application of the product developed by him. Janus Kindler (Warsaw Technical University) Participated at the conference as a representative of the Water Management Commission of the Academy of Sciences of Poland. It was pleasing to see that the papers submitted and the contributions have emphasized the importance of economics. There is ample literature available abroad on this subject. Continuous informal relationship should be maintained between Hungary and Poland also in the domain of water management. H. Herzog (VIZITERV) In the development of geotechnical preparatory and designing work the gaining popularity of two approaches is pointed out. In geotechniques as well as in geohydrology the use of electronic computers and analogue models is spreading. The results produced by the computer must be evaluated critically and in particular cases the problem to be solved must be examined by full-scale field tests from the aspects of economics or safety. This may be regarded the second typical development trend in geotechnical preliminary and designing work. The opportunities for such observations are believed to be substantially greater in number then those actually used. In the future increasing reliance should be made on fullscale field tests, further on the regular observation of completed structures. This would open the way for improving the methods of computation and the reliability of the results obtained. F. Papp (VIZITERV) In completing his paDer submitted, reported on experiences gained with filter drains already constructed and exposed to the effect of backwater. Field observations since the beginning of operation have demonstrated that in spite of permanent seepage no detrimental rise of the groundwater level has occurred in the areas behind the intercepting canals, and agriculture even enjoys the benefits of the intercepting system for two reasons. One reason is that the fluctuation in groundwater level which is detrimental to the plants has been eliminated, while on the other hand, the water collected by the intercepting canals is used for irrigation. The efficiency of the intercepting system has been verified and thus also the correctness of the dimensioning methods developed on the basis of field experiments. Gy. Varga (VIZITERV) A few additional comments have been presented on the paper submitted in which a comprehensive, general subject is discussed. For disseminating the advances of technology, regulatory publications of national and sectorial validity have been prepared, at the same time these have become increasingly difficult to overlook. In the course of engineering designing of water projects it would be necessary to observe more than 10 thousand regulatory publications. We have thus reached the stage where it is necessary to define the objectives of mechanical storage of such regulatory publications. The problem can only be solved in cooperation by the ministries interested in designing and construction, as well as by the Hungarian Office of Standard Specifications. The main problem in modernizing the designing process is to increase the share of creative work. Examining the process of completing a project, to construction drawings, 77 different phases could be identi-
