Programme de recherche sur les aspects biosphériques du cycle hydrologique

OBS: ... qui étudie les interactions de la végétation avec les mécanismes physiques du cycle hydrologique.

OBS: Core project of International Geosphere - Biosphere Program. BAHC is an interdisciplinary project combining and integrating expertise from many disciplines, in particular eco-physiology, pedology, hydrology, and meteorology. BAHC in this respect has a transfer function: on the one hand developing techniques and algorithms to provide climatic data needed for hydroecological research, thereby translating the results of the World Climate Research Programme (WCRP) into the scales relevant for studies of changes of the conditions at the land surface, and on the other hand, providing soil-vegetation-atmosphere transfer at larger scales, in particular, the areal pattern of heat and moisture fluxes according to land-surface heterogeneity. BAHC concentrates on investigations at scales where detailed studies of hydroecological processes are feasible in selected areas representing major ecosystems of the world and across boundaries between different ecosystems (ecotones, biome boundaries, etc.).
