The spnng is set with stones in a nature-like style, the plastic spout placed in the spring's ring refers to its regular use. 2. Bonc-well: (EOV X: 340180, EOV Y: 833480; asl. 295 m) The characteristic discharge is 0.6 l/min. Usually water appears only in the spnng pool, there is not any, or hardly any observable overflow Its temperature is highly variable, depends on the climate, the difference between the highest and the lowest values is 8.9 °C. Its annual average temperature is 9.3 °C. Chemical composition of the spnng changed during the research penod from calciumsulphate- hydrocarbonate type (3 r d month) to calciumhydrocarbonate-type (7 t h, 10 1 , 12 t h months) The spring is set with stones in a nature-like style, with a slimy pool of 70-50 cm in diameter and 30 cm depth. The water is sometimes blurred and stinky 3. Kádas-spring: (EOV X: 339580; EOV Y 834330; asl 177 m) Charactenstic yield is 1.5 l/min Meteorological circumstances play only a minor role in determining the spnngs temperature , the difference between the highest and lowest values is 2.6 °C, and the average temperature is 10.2 °C The chemical composition of the water did not change dunng the research penod, its composition is among the most constant ones, it is calcium- hydrocarbonate-type The natural-like capture of the spring is 90 cm times 50 cm rectangle which is 12 cm deep. The bottom is slimy. The capture is set with stones and wood. Significant number of newts (Tnturus cnstatus) and salamander (Salamandra salamandra) live in the spnng 4. Kocsis-spring: (EOV X:339070; EOV Y 834670; asl 148 m) Its charactenstic discharge is 2.8 l/min Its temperature is variable, highly dependent on meteorological circumstances. The difference between the highest and lowest values is the greatest among the measured springs, 11.8 °C. The average temperature of the water is 9 2 °C. Dunng the research penod the chemical composition of the water changed from calcium- hydrocarbonate- sulphate type (3 r d month) to calcium-hydrocarbonate type (7 t h, 10 t h, 12 t h months). The spnng's setting is made of stone, in a nature-like style. The slimy pool of the spring is a 100 cm times 60 cm rectangle, which is 15 cm deep. 5. Ispitály-spring: (EOV X 338730; EOV Y 835650; asl. 138 m) The characteristic discharge is 1.0 1/min. The temperature of the water is dependent on meteorological circumstances only to a small extent, the difference between the highest and lowest values is 3.2 °C. The annual mean temperature is 9.3 °C During the research penod the chemical composition of the water changed from calcium- sulphate- hydrocarbonate type (3 r d month) to calcium-hydrocarbonate type (7 t h, 10 t h, 12 t h months). The spnng regularly covered by debris and leaves The stone nature-like capture is 100 cm times 60 cm rectangle and 1-2 cm deep. 6. Sinka-well: (EOV X:341870; EOV Y:833830; asl. 335 m) It is protected, because of its charactenstic discharge is 7.8 l/min In the runoff of the spring the yield is increases with distance, because several seepage feeds the runoff. The runoff is fast flowing because the high gradient of the slope. The spring has high dissolved oxygen content and clear Its temperature is hardly dependent on meteorological circumstances, the difference between the highest and lowest values is 1.4 °C, the average is 9 3 °C. Dunng the research penod the chemical composition of the water changed in a small extent, from calciuinsulphate- hydrocarbonate type (3 r d month) to calciumhydrocarbonate-sulphate type (12 t h month) The nature-like setting of the spnng is stone The pool is shallow and slimy, it is a 80 cm times 40 cm rectangle. 7. Lengyelvályú-spring: (EOV X 342225; EOV Y: 833063; asl. 326 m) Out of the four branches of the spring group the two smaller ones are temporary , while the two bigger ones can be regarded as permanent , though it is possible that during longer rainless penods they also dry out. I earned out regular discharge measurements on the branch with the highest discharge. The spnng is protected because of its characteristic discharge of 11.6 l/min. The total discharge of the four branches reached 300 l/min during spnng, which is the highest value measured in this catchment area Its temperature hardly depends on meteorological circumstances, the difference between the highest and lowest values is 1.5 °C, with an average of 8.7 °C. During the research penod the chemical composition of the water changed from calcium- sulphate- hydrocarbonate type (3 rd month) to calcium- hydrocarbonate- sulphate type (7 t h, 10 t h months) then to calcium- hydrocarbonate type (12 l h month). The spring is in natural state 8. Nagysomi-erdészházi-spring: (EOV X 343410; EOV Y 832190; asl. 300 m) The charactenstic discharge of the spring is 2.3 l/min Its temperature is highly dependent on meteorological circumstances, the difference between the highest and lowest values is 3.4 °C. The annual average temperature is 9.0 °C. The chemical composition of the water stayed the same: calcium- natrium- sulphate- hydrocarbonate type, with a very small shift from sulphate to hydrocarbonate. The potassium content is the highest of the measured spnngs, at times (3 r d month) exceeds the amount of sodium The pool's diameter is 90 cm. It is encircled by stones, and the 40 cm deep, slimy pool is protected by an uncared wood cover. The water is sometimes milky and blurred 9. Nyúí-well: (EOV X: 342120; EOV Y: 835530; asl. 163 m) It has the highest discharge of the whole catchmentarea: 42.5 l/min This spnng is protected Because of the high yield of this spnng the Radvány stream from here becomes more significant The temperature of the spnng is hardly depends on meteorological circumstances, the difference between the highest and the lowest values is 3.4 °C. The average temperature is 8.1 °C. The chemical composition of the water is the most complex of the measured springs, in the research period it changed
