Abstract
This chapter addresses the need to predict and assess water resource availability and water-related natural hazards now and in the future using hydrological models. We survey recent developments including the use of global water models and water resources assessments. The range of modelling approaches is discussed, by considering the processes to be represented alongside more conceptual issues arising from incommensurable scales, uncertainty, and feedbacks. These motivate the second part of the chapter, which turns to the problems and opportunities for monitoring water, both for model calibration and validation, and to predict future change. Starting with the problem of monitoring networks in decline, the novel range of promising new technologies for measuring rainfall, soil moisture, and flow is evaluated. We conclude with an overview of how enhanced global modelling and monitoring will improve assessments of water resource availability and natural hazards under a changing climate.
