Résumé :
|
This thesis investigates the implications of the pressure dependency of outflows in water supply network systems in aspects of data management, mathematical modelling and reliability assessment. first "data reconciliation procedures" are developed, to improve the reliability of the collected field data. water consumptions and system leakage are evaluated more realistically. secondly, in respect of mathematical modelling, a head driven simulation method of analysing water pipe networks is presented.this analysis produces more realistic results without any significant loss of computational efficiency. finally a reliability measure to assess the hydraulic performance of the system is introduced. this measure is defined as the ratio of available outflow to the demand, according to probability of component failures. it is applied on experimental networks.
