A physically based, variable contributing area model of basin hydrology / Un modèle à base physique de zone d'appel variable de l'hydrologie du bassin versant

Abstract: Abstract.A hydrological forecasting model is presented that attempts to combine the important distributed effects of channel network topology and dynamic contributing areas with the advantages of simple lumped parameter basin models. Quick response flow is predicted from a storage/contributing area relationship derived analytically from the topographic structure of a unit within a basin. Average soil water response is represented by a constant leakage infiltration store and an exponential subsurface water stor… Show more

“…Two additional hypotheses, with a total of four resistance surfaces, were based on the TWI (Beven & Kirkby, 1979). The TWI is a simple hydrological model that uses a digital elevation model (a spatial representation of elevation across a landscape) to approximate the likelihood that water would accumulate at any single point under uniform rainfall conditions.…”

“…The first module allows separating surface runoff and infiltration with the Green-Ampt model. The second module represents subsurface downhill flow, and is driven by the TOPMODEL Darcy law adjustment (Beven and Kirkby, 1979). Finally the third module represents overland and channel flows.…”

“…The landslide depths were measured in the field after the triggering event in May 1999 (Andrecs et al, 2002) and derived from the analysis of a dDTM for the landslides triggered in August 2005 (Zieher et al, 2016). The final depths of the DCPTs were used to train generalized linear models (GLMs) with local morphometric parameters as predictors, including elevation, slope angle, minimum and maximum curvature (Wood, 1996), and the topographic wetness index (Beven and Kirkby, 1979). A stepwise backward predictor selection revealed a linear model with the slope angle yielding the best agreement with the cumulative landslide depths from 1999 and 2005 (Fig.…”
