INCA Versions and Applications

INCA logoVersions

Over the past 12 years the INCA suite of models have evolved to include the following:

  • INCA-N for flow, nitrate and ammonia
  • INCA-P for flow, total P, dissolved P, particulate P, macrophytes, epiphytes and phytoplankton
  • INCA-Sed for flow, sediments (including size fractions) and hydraulic parameters such as stream power and shear velocities
  • INCA-C for flow and carbon, including DOC, DIC and particulate carbon transport
  • INCA-Metals for flow, and metals (including arsenic, lead, cadmium, copper, nickel, chromium, manganese and molybdenum)
  • INCA-Mercury for flow, total mercury and methyl mercury INCA- Trit for radioactive pollution events

Range of Applications

INCA has been applied in a wide range of application, issues and scales. The table below shows a list of some of the applications ranging from catchments of a few Hectares up to very large catchments such as the Garonne at 56,000 km2
