    Dear all SAGA users,

    Since I often see questions about the various ways how to calculate Topographic Wetness Index (TWI) in SAGA, I think it would be interesting to link you to recently published paper about various methods for TWI calculation in SAGA and their comparison with measured field data (https://doi.org/10.1016/j.scitotenv.2020.143785). Unfortunately, the paper is behind the paywall, but you can find almost identical version here (https://www.researchgate.net/publication/346004523_Topographic_Wetness_Index_calculation_guidelines_based_on_measured_soil_moisture_and_plant_species_composition). If the community find the paper useful, it can be perhaps included also in SAGA References...

    BIG thanks to all SAGA Developers for this wonderful tool!

    Best regards,

    martin kopecký

    Hi Martin,

    thanks for the links! This is indeed interesting and helpful for people using the TWI. I've added the paper and links to the references section of the homepage.

    Thanks and best regards,
    Volker
