Book Synopsis Scale Issues in Hydrological Modelling by : J. D. Kalma
Download or read book Scale Issues in Hydrological Modelling written by J. D. Kalma and published by John Wiley & Sons. This book was released on 1995-09-11 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate models which address the management of land and water resources and ecosystems at large space and time scales. Theories of non-linear hydrological processes must be extrapolated to large-scale, three-dimensional natural systems such as drainage basins, flood plains and wetlands. This book reports on recent progress in research on scale issues in hydrological modelling. It brings together 27 papers from two special issues of the journal Hydrological Processes. The book makes a significant contribution towards developing research strategies for linking model parameterisations across a range of temporal and spatial scales. The papers selected for this book reflect the tremendous advances which have been made in research into scale issues in hydrological modelling during the last ten years.
Book Synopsis Inland Flood Hazards by : Ellen E. Wohl
Download or read book Inland Flood Hazards written by Ellen E. Wohl and published by Cambridge University Press. This book was released on 2000-07-03 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume was originally published in 2000 and presents a comprehensive, interdisciplinary review of issues related to inland flood hazards. It addresses physical controls on flooding, flood processes and effects, and responses to flooding, from the perspective of human, aquatic, and riparian communities. Individual chapter authors are recognized experts in their fields who draw on examples and case studies of inland flood hazards from around the world. This volume is unusual among treatments of flood hazards in that it addresses how the non-occurrence of floods, in association with flow regulation and other human manipulation of river systems, may create hazards for aquatic and riparian communities. This book will be a valuable resource for everyone associated with inland flood hazards: professionals in government and industry, and researchers and graduate students in civil engineering, geography, geology, hydrology, hydraulics, and ecology.

Available in PDF, EPUB and Kindle. Book excerpt: TO THE MODEL EVALUATION 1. MODELLING SOIL EROSION BY WATER l 2 John Boardman and David Favis-Mortlock 1 School of Geography and Environmental Change Unit Mansfield Road University of Oxford Oxford OX1 3TB UK 2 Environmental Change Unit University of Oxford 5 South Parks Road Oxford OX1 3UB UK Introduction This volume is the Proceedings of the NATO Advanced Research Workshop 'Global Change: Modelling Soil Erosion by Water', which was held on II-14th September 1995, at the University of Oxford, UK. The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.

This book was released on 2015-01-08 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le present travail a pour cadre geographique la zone sahelienne de l'ouest du Niger. Il a concerne les deux principales formations geologiques a savoir le socle cristallin du Liptako et le bassin sedimentaire des Iullemmeden. L'objectif de ce travail est de mener une etude comparative de l'erosion et du ruissellement sur le socle du Liptako et le bassin sedimentaire des Iullemmeden. Pour atteindre les objectifs assignes, un suivi temporel des etats de surface et une quantification du ruissellement et erosion sont realises sur des parcelles a differrentes repetitions.Les resultats obtenus permettent de constater que le coefficient de ruissellement est plus eleve sur le site du socle, tant a l'echelle de la parcelle qu'a celle du bassin versant elementaire et laisse penser que la formation geologique pourrait influencer les reponses hydrodynamiques du sol. Les bassins versants du socle ruissellent plus que ceux du bassin sedimentaire. Cette etude a aussi permis de comprendre la variabilite de l'erodibilite intra etats de surface."

Book Synopsis Modèlisation orientée décision des processus de transfert par ruissellement et subsurface des herbicides dans les bassins versants agricoles by : Florent Tortrat
Download or read book Modèlisation orientée décision des processus de transfert par ruissellement et subsurface des herbicides dans les bassins versants agricoles written by Florent Tortrat and published by . This book was released on 2005 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'utilisation des produits phytosanitaires dans l'agriculture moderne pose un problème pour l'équilibre des écosystèmes et la santé de l'homme. Un des problèmes majeurs est la dégradation de la qualité de l'eau de surface et de l'eau souterraine pour la consommation et la qualité des écosystèmes aquatiques. Il existe un réel besoin d'outils opérationnels facilitant l'agrégation des processus de transferts au niveau des bassins versants à des fins de maîtrise des contaminations des eaux par les produits phytosanitaires. La plupart des outils opérationnels sont des indicateurs environnementaux, rapides et simples d'utilisation. Cependant, ils ne donnent que un niveau de risque et n'intègrent pas ou très peu l'incertitude liée à des critères spatiaux et temporels. Cette thèse propose un modèle orienté décision des transferts par ruissellement et subserface des herbicides. Il vise à produire une évaluation semi-quantitative de la contamination des eaux de rivière par les herbicides à l'échelle de petits bassins versants agricoles (quelques dizaines km2) au cours de quelques mois suivant les traitements. Une nouvelle représentation spatiale a été proposée. Elle est basée sur la spatialisation des pratiques agricoles et des processus physiques de transferts du bassin versant sous la forme d'un arbre d'exutoires de parcelles. Ce niveau de représentation permet une modélisation réaliste, opérationnelle et répondant aux besoins des acteurs locaux. Le modèle intègre le réseau de haies structurant l'espace du bassin versant. Les processus majeurs de transfert des herbicides dans les bassins sur socle sont le ruisselement et les écoulements de subsurface.
