CARBON and HYDROLOGY (WP2)

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.

• 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

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...
