摘要
This paper presents some results of a study on the identification of flood formation processes and their modelling in the geographic context of the Swiss Plateau. With the help of hydrometric measurements at different scales, groundwater depth measurements or isotopic tracing (O-18), it is shown that all three processes mentioned in the literature (subsurface flow, and saturation excess and infiltration excess overland flow) occur in the Haute-Mentue catchment (12.5 km2). For heavier floods, however, overland flow predominates, with a proportion of new water in the flood rarely encountered in the literature. Under these conditions, the location of contributing areas, which is essential for a physically based model, proves to be difficult to determine. In particular, the use of a topographic ind'' is not entirely satisfactory. An attempt is made to show the difficulties in describing the complexity of the catchment's response to precipitation and, consequently, the limitations when deterministic physically based model are used.
