Budapest, 2000. * * * Thoughts on the past and present of the regualtion of the River Tisza, in the occasion of the 150 year anniversary of Jenő Kvassay by Dr. Béla HAJOS and László FEJER, civil engineers In the year 2000 the Hungarian Water Service celebrated the 15 t h anniversary of the birth of Jenő Kvassay, the creator of the unified state administration for water management in this country. His first water related work — Vizeink" (our waters) (Figure / .) —was dealing mainly with the regulation of the River Tisza (Figure 2.). The large floods of the past three years made it timely to review again the experiences of the regulation works of the River Tisza, which was made in the 19 t h century. In the second and final stage of these works the Hungarian Water service (headed by Kvassay) had an important role (Figure J.). In the times when he was not in the position of substantially affecting the ways and means of the water regulation works, Kvassay was of a more radical opinion concerning the regulation. He claimed that the multiple cutting off of the meanders of the river, in order to accelerate the passing of floods, and the building of dikes which leave a relatively narrow flood-berm only, would not solve the flood problems on the long run. He suggested the putting of more emphasis on the building of large flat-land reservoirs and spillway canals (Figure 4.). By the end of the 1880-ies, when he was in charge of the Hungarian Water Service, directing the review of the Tisza regulation works, the concept of bypass canals and reservoirs was abandoned. His new concept was focussing on channel and levee-line corrections, based on accurate hydrometric measurements, and to facilitate the irrigation of land beyond the levees and to establish the Hungarian system of navigation waterways (Figure 5.). In Hungary the concept of the defence against the floods of the Tisza valley and of the prevention of the occurrence of these floods (Figure 6.) is being expanded to include new elements. The defence against excess waters (Figure 7.) gained new emphasis. Interests of nature conservation gained new priorities over those of the merely economically driven water management. In course of Hungary's joining the European Union there will be changes in the structure of agricultural land uses. In this context the interests of nature conservation will gain new priorities in the flood-plains, along with the priorities of flood release. Along with the remembering some of his thoughts the flowers of remembrance (Figure 8) also represented the recognition and appraisal of his work also in our era.
