<82) It is intended to establish similarity criteria for transferring mass transfer results obtained in models into prototypes. In continuation of the project aeration methods which offer the greatest advantages under domestic conditions will be investigated, and directives will be given for general practice. 3. Erosion, stream bed evolution, sediment transportation 3.1 Relationship between factors resulting in, and affecting, erosion and soil loss. (Studies in experimental areas by changing individual factors.) 3.2 Investigation into the applicability of the usual soil-erosion calculation methods (formulae) for conditions prevailing in Hungary. 3.3 Area transfer of erosion products, resp. their participation in sediment transportation. Mass ratio of erosion products deposited over the area and entering into the watercourse. 3.4 Influence of the permeability of the terrain and subsoil on erosion conditions. 3.5 Effect of various soil conservation practices on reducing erosion and their economic consequences. 3.6 Effect of erosion in the drainage basin on sediment transportation in streams3.7 Investigation of laws governing sediment formation in the bed. 3.8 Investigation of sediment transportation phenomena in the river bed: a

) Investigation of individual phases of sediment transportation phenomena. b

) Determination of relationships between bed material and diminution of particles along the watercourse. c) Investigation of fundamental phenomena of sediment wear and diminution. 3.9 Determination of relationships between the dynamic characteristics of sediment movement and particle size. Man's influence on hydrological phenomena 4.1 Effect of river canalization on river regime, sediment transportation, bedmorphology and groundwater household in the environment. 4.2 Forecasting anticipated hydrological changes following the construction of contemplated river barrages. 4.3 Effect of changes in land use on run-off conditions and surface drainage in plain regions. 4.4 Effect on the moisture household of soil due to the application of advanced cultivation techniques. 4.5 Effect of irrigation on groundwater conditions. 4.6 Effects of the increased utilization of groundwater resources on changes and recharge of total water resources. D) EDUCATION AND TRAINING Information on the situation of hydrologist training and hydrology education in Hungary, on possible help offered by Hungarian hydrologists in this field to other nations, respectively on help expected from other nations and UNESCO, was supplied in questionnaire NS/573/11/95 circulated by the General Director of UNESCO. It should be pointed out here that during the Decade Hungary is willing to offer on the average two scholarships annually to foreign specialists and has announced its readiness to organize under the sponsorship of UNESCO a hydrological seminary in English for participants from abroad.
