Urban hydrological processes are characterised by high land-use variability and short response times as a result of typically high degrees of imperviousness. As a result, urban catchments are especially sensitive to space-time variability of precipitation at small scales. High resolution precipitation measurements are crucial for cities to properly analyse and predict urban hydrological response. This session focuses on high resolution precipitation measurement in cities and use of these data for urban hydrological response analysis modelling at urban scales, i.e. down to street level:
- Novel techniques for high resolution precipitation measurement in cities and approaches for merging remote sensing data with in situ measurements to obtain representative urban precipitation fields;
- Novel approaches to modelling urban catchment properties and hydrological response, from physics-based models, fully and semi-distributed modelling to stochastic and statistical conceptualisation;
- Applications of measured precipitation fields in urban hydrological models to understand and characterise urban hydrological variability and predict hydrological response.
