'The mathematic models we use enable us to analyse various complex networks'

Tamás Huzsvár and Richárd Wéber, PhD students of BME Faculty of Mechanical Engineering, Department of Hydrodynamic Systems examine the network theory and energy emission aspects of potable water networks. Their lecture was awarded a special award and a Public Choice Award on the potable water- and sewage system technology-related Dulovics Junior Symposium. Interview. 

What do you study in your PhD researches? 

Richárd Wéber: We both would like to build up and precise mathematical models of potable water networks, and draw overall conclusions about their operation. Our aim is that potable water should be transferred in proper quantity, most efficiently and inexpensively, to the consumers. We work based on the 1D hydraulic model of potable water networks, using mathematical tools of network theory.

What challenges can reduce the efficiency of these networks?

Richárd Wéber: For instance, there are vast quantities of leakages, due to the erosion of the pipes. It is pumped into the network, but no one pays for it, it is called non-invoiced water. There are methods to estimate the locations and how to reduce this loss. It is otherwise not necessarily secure, because these elements are located 1-2 meters underground, so it is costly and uncomfortable. More
