  abstract = {{T}his paper presents a coupled observation and modelling strategy aiming at improving the understanding of processes triggering flash floods. {T}his strategy is illustrated for the {M}editerranean area using two {F}rench catchments ({G}ard and {A}rdeche) larger than 2000 km(2). {T}he approach is based on the monitoring of nested spatial scales: (1) the hills-lope scale, where processes influencing the runoff generation and its concentration can be tackled; (2) the small to medium catchment scale (1-100 km(2)), where the impact of the network structure and of the spatial variability of rainfall, landscape and initial soil moisture can be quantified; (3) the larger scale (100-1000 km(2)), where the river routing and flooding processes become important. {T}hese observations are part of the {H}y{M}e{X} ({HY}drological cycle in the {M}editerranean {EX}periment) enhanced observation period ({EOP}), which will last 4 years (2012-2015). {I}n terms of hydrological modelling, the objective is to set up regional-scale models, while addressing small and generally ungauged catchments, which represent the scale of interest for flood risk assessment. {T}op-down and bottom-up approaches are combined and the models are used as "hypothesis testing" tools by coupling model development with data analyses in order to incrementally evaluate the validity of model hypotheses. {T}he paper first presents the rationale behind the experimental set-up and the instrumentation itself. {S}econd, we discuss the associated modelling strategy. {R}esults illustrate the potential of the approach in advancing our understanding of flash flood processes on various scales.},
