When estimating runoff and erosion on hillslopes, most scientists consider only the soil. But the weathered bedrock underneath may plan an equally important role in channeling water, nourishing plants and shaping the landscape, according to UC Berkeley geologists. William Dietrich and Daniella Rempe propose a model to predict the depth of weathered bedrock from easily measured parameters, providing a bottom-up approach to predicting topography and improving climate models that now take only soil...
