This model driver couples ecohydrologic processes of solar radiation, probabilistic soil moisture, annual net primary productivity, detachment limited fluvial erosion and hillslope diffusion mediated by biomass.

Literature: The radiation model and radiation ratios are based on methods in Bras, R. L.: Hydrology: an introduction to hydrologic science, Addison Wesley Publishing Company, Boston, Mass., USA, 643 pp., 1990.

Soil mositure model is based on: Porporato et al 2004: Porporato, A., Daly, E., & Rodriguez‐Iturbe, I. (2004). Soil water balance and ecosystem response to climate change. The American Naturalist, 164(5), 625-632.

Biomass is considerd to reflect the highest grass/shrubland biomass [gr/m2] in a year (Annual Primary Productivity) and calculated as a function of mean annual actual ET scaled by plant water stress. ANPP equation used is from: Webb WL, Szarek SR, Lauenroth WK, Kinerson RS. 1978. Primary productivity and water use in native forest, grassland, and desert ecosystems. Ecology 59(6): 1239–1247. DOI: 10.2307/1938237
