Presentation Transcript

  1. CARBON and HYDROLOGY (WP2) • The main purpose of the hydrological study is to quantify fluxes/stores of carbon (and nutrients) in water phase as it travels through the ecosystem (WP 2) • The activities will be carried out in the CARBONSINK project, in collaboration with the ECOCARBON project • The selected Cuieiras catchment is a 5 km2 area near Manaus.

  2. COMPONENTS/MEASUREMENTS • Rainfall measurements and water chemistry dissolved and particulate matter • Streamflow, amount of water leaving the catchment will be measured at catchment outlet and samples will be collected for chemical analysis of C (particulate) and nutrients (N,P,K,Ca,Mg and Al) • A UV-VIS probe will be used to continuously monitor TOC & nitrate levels in streamwater

  3. Status • Site selected, research strategy determined • Collaborators in Brazil identified • Equipment reviewed and ordered • Model installed • Digital elevation model and element network generated, model input parameter files made

  4. Hydrological modelling • The TOPOG model will be used to simulate long-term discharge and carbon losses, etc. • Model calibration using measured discharge • Input: several years of rainfall and other tower weather data, soil maps, vegetation • Digital elevation model has been prepared, as well as preliminary soil/vegetation input files and a one-year climate data file. • Waiting for measurements to calibrate...

  5. DEM and Element network of Cuieiras catchment

  6. Slope and Aspect of the Cuieiras catchment
