[Termes IGN] structure hiérarchique de donnéesRésumé : (Auteur) The monolithic structure of process-based environmental models has become a major obstacle in dealing with complex environmental problems. Interoperability is the inevitable direction for future generations of models. This article discusses the identification of equation functions for interoperable environmental models. These equations represent environmental processes that are implemented as algorithms in the models. The identification of common equations in existing models helps develop equation components that can be assembled to form customized models. In the context of a semantic reference system, formal concept analysis is used to decompose existing models, extract the common equations embedded in them, and organize these equations in a hierarchy of a concept lattice. The hierarchical structure of the lattice helps identify the relationships between equations across different levels and within the same level. Insights drawn from the concept lattice provide valuable information for the framework design of customized models and the adaptation of algorithms from existing models for the development of equation components. An important hydrological process, surface runoff, is used as an example of an environmental process to illustrate the analysis. To support the discussion, a customized surface runoff model is built using three components extracted from several existing hydrological models to predict surface runoff of a watershed.

[Termes IGN] VBARésumé : (Auteur) (Auteur) Soil erosion is one of the most serious problems in the mountainous areas. Geographic Information Systems (GIS) are widely applied to predict soil erosion, as all factors on soil erosion can be extracted by spatial analysis. Therefore, the quality of spatial data plays a great role on the prediction and the most appropriated data should be used for input data to the model.
The purpose of this study is to evaluate the sensitivity of GIS data quality for the Revised Universal Soil Loss Equation (RUSLE) model. Different quality of GIS data input for two catchments in Switzerland and a catchment in Thailand are applied to the calculation. A programmed Visual Basic Application (VBA) extension on ArcGIS 9.2 and the geostatistics analysis are used for the calculation.
Moreover, the study aims to improve the soil erosion prediction, experienced from the study, using GIS technology. In order to achieve the aim, the study recommends, different methods : the use of GIS database of different soil-scales, the soil GIS data sharing, the Web-based GIS soil data and the soil erosion metadata model.
From the study, the developed algorithm (VBA application) is implemented on ArcGIS 9.2 Interface and has shown to be a good tool for the RUSLE model in the study areas. The results of the study present that in the heterogeneous slope area, the finer Digital Elevation Model (DEM) yields more accurate the soil erosion values. In contrast, in the flatter area, coarse DEM derives similar results to the finer ones. The finer OEMs are expensive, therefore it should be used as necessary.
Also, the channelization results using different methods, which combine DEM and a Vector River Network (VRN), are completed. The results show that the VRN is very effective to identify the channels starting points. The study highly recommends to combine the VRN with the DEM for channelization in all cases.
Furthermore, the soil erosion metadata model is established conforming to the ISO 19115. It is found that the basic GIS data (DEM, Vector River Network, etc.) can apply to ISO 19115, but specific metadata (soil types, cropping types, etc.) is needed to identify the particular data. Altogether, the GIS data transfer, the interoperability in GIS, a unique standard for soil classifications, Spatial Data Infrastructures (SDI) and the soil erosion metadata model should be completed for all soil data in order to share all data from different sources or organizations. The methodologies will support all users to access the most appropriate GIS data and then obtain the more accurate soil erosion.Note de contenu : Chapter 1 Introduction

[Termes IGN] ruissellementRésumé : (Auteur) This study investigates the changes in simulated watershed runoff from the Agricultural NonPoint Source (AGNPS) pollution model as a function of model input cell size resolution for eight different cell sizes (30 m, 60 m, 120 m, 210 m, 240 m, 480 m, 960 m, and 1920 m) for the Little River Watershed (Georgia, USA). Overland cell runoff (area-weighted cell runoff), total runoff volume, clustering statistics, and hot spot patterns were examined for the different cell sizes and trends identified. Total runoff volumes decreased with increasing cell size. Using data sets of 210-m cell size or smaller in conjunction with a representative watershed boundary allows one to model the runoff volumes within 0.2 percent accuracy. The runoff clustering statistics decrease with increasing cell size; a cell size of 960 m or smaller is necessary to indicate significant high-runoff clustering. Runoff hot spot areas have a decreasing trend with increasing cell size; a cell size of 240 m or smaller is required to detect important hot spots. Conclusions regarding cell size effects on runoff estimation cannot be applied to local watershed areas due to the inconsistent changes of runoff volume with cell size; but, optimal cells sizes for clustering and hot spot analyses are applicable to local watershed areas due to the consistent trends.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) En Seine-Maritime, le ruissellement érosif pose d'importants problèmes : source de pollution de la ressource en eau, il est également à l'origine d'événements chroniques, parfois catastrophiques, d'inondations par crue turbide. Ces phénomènes sont complexes et difficiles à quantifier : une complexité liée autant aux structures hydromorphologiques en place qu'à la variabilité infra- et interannuelle des couverts agricoles. En complément du SIG, l'utilisation d'un outil de modélisation à base d'automate cellulaire a permis d'apprécier plus finement le comportement des bassins et d'établir un diagnostic des sensibilités au ruissellement pour les espaces considérés. Au-delà de sa fonction de modélisation, cet outil est venu appuyer le « dialogue » et la concertation dans le cadre d'une recherche visant à modifier les pratiques individuelles des exploitants agricoles.
