9-10. szám - Értekezések - J. BOGÁRDI, D. Eng.: Report on the Ground Water Conditions of the Great Hungarian Plain

On the hasis of the three figures it may be said that in rainy-cool years no relationship can be fonnd hetween the stages, in average years only sligíht or patrial relationship is apparent, while in arld-hot years the relationsthip is proven. The foregoing brief approximate comparison shows therefore that the ground water stages are in closest corrélation wiht the climatic conditions. In the case of extreme precipitation this corrélation is not manifest, just beeause the decisivé but disturbing influence of the precipitation. Naturally the examination does not assert that there exists no corrélation hetween the stages and the precipitation. Sueh corrélation evidently exists but its expression is very complicated since many ohter factors would liave to be considered at the examination. Finally we wish to submit íőr a more detailed illustration of the ground water conditions of the Nagy Magyar Alföld (Great Hungárián Lowland) situation plans with hydroisoliipsas of a year with a rainy-cool spring and of a year witih a comperativeiy arld-hot fali. The situation plans with hydroisohipsas were made on the basis of mean stages of eaoh montlh whioh were taken into accóimt for each well separately.
