Modeling the geometry and volumes of alluvial infill at the bottom of river valleys is essential for a better understanding of river dynamics and alluvial storage, which buffers sedimentary signal transmission from source to sink. This study introduces kriging methods for predicting alluvial thickness geometries in the valley bottom using random fields with nonstationary geometric anisotropies. These anisotropies are construct...

The study of alluvial terraces helps in reconstructing the past geometries of rivers and makes it possible to assess the rate and pattern of fluvial incision and bedrock uplift. The fluctuations of river base levels are particularly variable and complex during the Late Quaternary in the lower course of rivers due to the interplay of responses to sea‐level fluctuations, tectonics and glacio‐isostasy. In this paper, the geometry...
