Abstract
An experimental landscape simulator has been developed which uses a rainfall simulator to create overland flow and erosion. The simulator uses rainfall sprinklers that eliminate rainsplash and an artificial soil which has little cohesion. Experimental landscapes developed in the simulator evolved according to Howard's headward growth model. Elements of Glock's model could be identified during evolution (i.e. initiation and maximum extension), but other stages of this model were not observed (i.e. extension and integration). The Horton concept of cross‐grading and micropiracy and stream piracy was not observed despite the dominance of overland flow, nor the groundwater headward growth mechanism proposed by Dunne, the latter due to experimental design, which eliminated any perched groundwater table. The experimental apparatus produced model landscapes that are scaled‐down analogues of real world processes. Copyright © 2001 John Wiley & Sons, Ltd.

## Abstract A new integrated hydrological and nitrogen model, called TNT2 (topography‐based nitrogen transfer and transformation), has been developed to study nitrogen fluxes in small catchments. This model, process‐based and spatially distributed in order to take spatial interactions into account,
Flame-vortex interactions constitute a basic problem in the analysis of turbulent combustion. Vortex rollup is also found to be one of the major driving mechanisms of combustion instabilities. While there are many analytic and numerical studies of the process, the number of detailed experiments is r
