Research site: Mule Hole forest catchment
Research theme: fractured crystalline-rock aquifer
In dry tropical forests, which account for one third of the forested areas, annual rainfall and potential evapotranspiration are in the same range and therefore vegetation has to optimize the water resource. Future climate changes, likely marked by a greater frequency of severe climatic events like floods and droughts, are expected to increase the vulnerability of these ecosystems. Understanding their hydro-biogeochemical functioning in the long term is therefore an essential condition for anticipating future changes, particularly in biodiversity. Critical Zone Observatories (CZO) in dry tropical environment are scarce, partly due to the difficulty of measuring hydro-biogeochemical fluxes exported mostly by ephemeral streams or groundwater discharge. The 4.1km2 Mule Hole experimental catchment, located in south India (11°72’N, 76°42’E) in the Kabini River Basin, was initially set up to estimate the variations of water and elemental mass balances in response to pluri-annual monsoon fluctuations and climate change. The present data set consists of (1) meteorological data (rainfall amount and chemical composition, air temperature, relative air humidity, wind speed and direction, global radiation) (2) Hydro-geochemical data (stream discharge and chemical composition, suspended particulate matter) (3) Hydrogeological data (piezometric levels and groundwater chemical composition. This dataset has already been used to assess the stream and groundwater fluxes exported from the catchment and the role played by the forest vegetation to control these fluxes. It also allowed building hydrological models in relation with forest dynamics and notably deep root uptake. This dataset may be further used to study the carbon cycle, weathering processes and associated CO2 consumption in tropical dry forests, and the role of forest diversity on the biogeochemical cycles.
