- Assessing a numerical cellular braided-stream model with a physical model
- Chenal anastomosé ; Concept ; Cours d'eau ; Dynamique fluviale ; Géométrie hydraulique ; Modèle ; Modèle numérique
- Braided channel ; Channel geometry ; Concept ; Fluvial dynamics ; Model ; Numerical model ; Stream
- The AA. test the representation of braided channel morphodynamics in the Murray-Paola model, MP model, against the known characteristics (mainly from a sequence of high resolution digital elevation models) of a physical model of a braided stream
- . It achieves this by initiating the model from real braided topography rather than white noise. This extension of the application of the MP model is used to identify characteristics that are not reproduced, to investigate their causes, propose modifications
- and discuss both the implications for the formation of braiding and alternative modelling strategies.

- Crue glaciaire ; Glaciaire ; Géomorphologie ; Impact ; Modèle ; Sédimentologie
- Geomorphology ; Glacial features ; Glacial surge ; Impact ; Model ; Sedimentology
- The aim of this paper is first to describe the laboratory procedure by which field jökulhlaups were replicated using physical-scale modelling techniques, and second to investigate whether the modelled jökulhlaups characterized by contrasting
- hydrograph shapes produced different sedimentary and geomorphic impacts. For this purpose, an exponentially rising and a linearly rising jökulhlaup were modelled.

- A review of scaling theory for hardware models and application to an urban dew model

- Climatology ; Model ; Moisture ; Radiation ; Scale ; Temperature ; Urban climate
- This paper reviews scaling theory for hardware models for physical geographers, especially those interested in micro- and urban climates, and out-of-doors models. Criteria addressed dealt with physical domains (i.e., space, time, and temperature
- fields), physical processes such as radiation, conduction and convection, and discrete enclosures such as buildings. A case study from the field of urban climatology is presented : the out-of-doors scale model constructed by the A. to study urban dew.

- The effect of surface curvature of the deposition of loess : a physical model
- Eolien ; Géographie physique ; Loess ; Modèle physique ; Sédimentologie ; Technique de recherche ; Turbulence atmosphérique
- Physical geography
- The model is tested in a sedimentation experiment with a symmetrical hill (with length axis perpendicular to the flow direction) in a wind tunnel. It appears both from the model and the experiment that loess deposition will occur preferably

- Cours d'eau ; Erosion des berges ; Géométrie hydraulique ; Modèle ; Modèle conceptuel ; Méandre ; Transport sédimentaire
- Bank erosion ; Channel geometry ; Conceptual model ; Meander ; Model ; Sediment transport ; Stream
- A simple analytic model is presented relating local sediment transport capacity to variance in the transverse shear stress distribution in a stream channel. The model is used to develop a physically based conceptual model for the initiation
- Rainfall induced soil seal. (A). A critical review of observations and models

- Luxembourg ; Model ; Numerical model ; Precipitation ; Rill wash ; Slope ; Soil properties
- This paper describes the results of tests undertaken on a physically-based runoff model regarding its predictions at the detailed hillslope scale. These results are compared with field observations from a Luxembourg hillslope with pseudo-gley soils
- developed on Keuper Marl where discharge via overland flow and throughflow is intermittent during the year. Observed seasonal variation of hydraulic conductivity is included in the modelling.
