Slope gradient controls soil thickness and chemical weathering in subtropical Brazil: Understanding rates and timescales of regional soilscape evolution through a combination of field data and modeling KU Leuven
Soil thickness and residence time are regulated by a dynamic interplay between soil formation and lateral transport of soil particles and solutes. To unravel this interplay and infer patterns and rates of chemical weathering, soil physical and chemical properties can be used. Here, we present an integrated approach combining numerical modeling with field measurements to assess the impact of slope gradient on soil thickness and chemical ...
