Book Description
Ce mémoire présente un modèle complexe des transferts de masse et de chaleur entre un sol nu et l'atmosphère. Un code numérique en éléments finis adapté à la présence de stratifications pédologiques est développé. Les résultats des calculs montrent un bon accord avec les observations expérimentales effectuées sur une parcelle agricole de 3600 m2. Le modèle est alors utilisé pour analyser les processus physiques intervenant dans la dynamique des transferts s'appuyant sur ces analyses, un modèle simplifié est présenté et une approche vers une paramétrisation des flux d'évaporation est analysée en introduisant le concept de résistance à la surface du sol.

Deterministic Methods in Systems Hydrology
Author: James C.I. Dooge
Publisher: CRC Press
ISBN: 1351989383
Category : Science
Languages : en
Pages : 336
Book Description
Deterministic Methods in Systems Hydrology presents the basic theory underlying the multitude of parameter-rich models which dominate the hydrological literature. Its objectives are to introduce the elements of systems science as applied to hydrological problems; to present flood prediction and flood routing as problems in linear systems theory, clarifying the basic assumptions and evaluating their accuracy; and to review and to evaluate some deterministic models of components of the hydrological cycle, with a view to assembling the most appropriate model of catchment response, for a particular problem in applied hydrology. The material is developed in two parts: the first four chapters present the systems viewpoint, the nature of hydrological systems, some systems mathematics and their application to direct storm runoff. The final four chapters cover linear conceptual models of direct runoff, the fitting of conceptual models to data, simple models of subsurface flow and non-linear deterministic models.

Book Description
This Festschrift containing sixteen invited essays and papers is a tribute to the distinguished Irish hydrologist James Dooge on the occasion of his 70th birthday. His former students, colleagues and friends in fourteen countries, have provided a varied selection on his favourite topics: flow in open channels and unsaturated soil, and also from his major interest of recent years, large scale hydrology and global change. The book has three sections. The first section on hydrological processes contains six papers. The second section on large scale hydrology has four papers. Six historical, reflective and philosophical essays on the past and future of the hydrological sciences form the third section of the book.

Land Surface Evaporation
Author: Thomas J. Schmugge
Publisher: Springer Science & Business Media
ISBN: 1461230322
Category : Science
Languages : en
Pages : 422
Book Description
General circulation model (GCM) experiments in the late 1970's indicated that the climate is sensitive to variations in evaporation at the land surface. Thus, in the context of climate modeling, it became important to develop techniques which would realistically estimate the evaporation flux on land. Land Surface Evaporation: Measurement and Parameterization discusses strategies for the use of experimental data in developing and testing parameterization schemes of the evaporation flux in GCM's. The book reviews state-of-the-art techniques, such as remote sensing, which measure evaporation fluxes over continental surfaces. It evaluates their relevance with respect to the various spatial and temporal scales of interest. This book will provide researchers in climatology, meteorology, hydrology and water management, and remote sensing with a thorough overview of current research in land surface evaporation. It will also give young scientists insight into surface processes.
