The paper presents the methodology for the combined use of GIS-based multi-criteria analysis and simulation-optimisation modelling for management of the groundwater resources of the Dore river basin in France. The study identifies the suitable location and maximum discharge for the new groundwater pumping wells. The multi-criteria analysis (MCA), with the(More)
Ground management problems are typically solved by the simulation-optimization approach where complex numerical models are used to simulate the groundwater flow and/or contamination transport. These numerical models take a lot of time to solve the management problems and hence become computationally expensive. In this study, Artificial Neural Network (ANN)(More)
Abstrad-The paper presents the development of a real-time expert system (RTES) for supervision and fault detection in urban drainage systems (UDS). Several vita1 characteristics of such an expert tool, in which the project is being developed, are recalled. The main aspects of the modelling of the UDS and the detection of faults are outlined and illustrated(More)

Artificial Neural Networks (ANNs) have been found to be a robust tool to model many non-linear hydrological processes. The present study aims at evaluating the performance of ANN in simulating and predicting ground water levels in the uplands of a tropical coastal riparian wetland. The study involves comparison of two network architectures, Feed Forward(More)
Type 2 diabetes, whose prevalence has increased among elderly aged over 75 years, has a number of specific features which differ from that in young people: heterogeneous population, association with other cardiovascular risk factors and several comorbidities, different therapeutic constraints and risks, and lower life expectancy. By using a standardized(More)
Future climate changes and the resulting modifications in anthropogenic activities will alter the interactions between rivers and groundwater. The quantification of these hydraulic interactions is absolutely necessary for achieving sustainable water use and requires accurate analytical methodologies. This report proposes an interdisciplinary approach to the(More)
