KARST WATER LEVEL PREDICTION BY DATA OF THE BüKK KARST WATER LEVEL MONITORING SYSTEM

To define the exploitable water reserve of Bükk is important to support the sustainable water-supply of Miskolc. The prior water level prediction method was a trend line fitting method on measured data of a concrete monitoring point. The expectable character of water level change was determined by extension of trend line. End of 2011 the karst water level was decreased under absolute minimum value of 20 years database. Inspection of prior prediction method and find alternative prediction possibility was justified by that enormous decrease. A characteristic curve was created from data line of 20 years which shows the draining process of karst in exorbitantly arid period. That curve can fitted to any water level and probable karst water level is predictable if infiltration is zero after that point.
