Does anyone know the formula behind mass balance index implemented in SAGA-GIS? Any references on this? Any information on what the index represent and how it can be interpreted?
to my knowledge, the MBI implemented in SAGA-GIS is different from the MBI introduced by Böhner & Selige. More details to the SAGA-GIS variant including formular and application examples can be found in the following articles:
Möller, M., Volk, M., Friedrich, K., Lymburner, L., 2008. Placing soil-genesis and transport processes into a landscape context: A multiscale terrain-analysis approach. Journal of Plant Nutrition and Soil Science 171 (3), 419-430.
Möller, M., Koschitzki, T., Hartmann, K.-J., Jahn, R., Jan. 2012. Plausibility test of conceptual soil maps using relief parameters. CATENA 88 (1), 57-67.
Thank you both. Indeed, the formula form Böhner and Selige seems to be different from what SAGA produces. I will check the articles specified by Markus. Thank you again.
