Evaluation des simulations spatiales

2006

The general topic is the evaluation of prospective scenarios for urban planning, especially for the management of urban built up areas. Several models of land-use and land-cover change (LUCC), based on different assumptions, allow producing realistic simulations of urban growth. Three ways can be distinguished for measuring the quality of modelings: 1. The choice of a model and its calibration; 2. The validation (showing if results are realistic); 3. The evaluation (showing if results respect defined planning goals). Measurement methods must be associated to these three steps.

Potential implications of climate change and urbanization on watershed hydrology

2017

Abstract This paper proposes a modeling framework able to analyze the alterations in watershed hydrology induced by two recurrent drivers for hydrological changes: climate change and urbanization. The procedure is based on the coupling of a stochastic weather generator with a land use change model for the generation of some hypothetical scenarios. The generated scenarios are successively used to force a physically-based and spatial distributed hydrological model to reconstruct the basin response under different conditions. Several potential climate alterations are simulated by imposing negative and positive variations in the mean annual precipitation and a simultaneous temperature increase.…
