Quantitative UWS performance model: WaterMet2

Abstract

The WaterMet2 tool encapsulates a conceptual, mass balance based model that enables quantifying the performance of an integrated urban water system (UWS) over a prolonged period of time (typically years) with a daily time step. The model allows quantifying the UWS performance, both water quantity and quality related, at different spatial scales and with particular focus on sustainability related performance. The WaterMet2 covers the full urban water cycle and provides means of evaluating the impact of different potential intervention strategies in the context of strategic level, long-term future decision making. It also provides basis for the assessment of various risks associated with the UWS performance.
