MODELLING-MEASUREMENT-IDENTIFICATION AND THEIR IMPORTANCE IN CONTROLLING WATER SUPPLY SYSTEMS

Abstract

In case of the revision of a settlement's water distribution system, different models of the whole system must be developed. In course of modelling we certainly make some approximations, thus there are certain differences between model and reality. Consequently, it must be determined, to what degree the model conforms to reality. To prove the conformity of the model to reality, measurements and calculations of the hydraulic parameters must be done for some operation conditions, and the results must be compared. We have made measurements and identifications in Bratislava and in several regions of Hungary, one of them, the basic zone of Miskolc city is presented. On the basis of comparison of the calculated and measured values, the identification can be considered as completed (Fig. 4.), the values entirely conform to each other.
