  • Surface-Based Morphometry
    Brain Mapping, 2015
    Co-Authors: J. Shi, Yalin Wang
    Abstract:

    Surface-based human brain mapping methods and statistical morphometric analyses are attracting more interests, due to their subvoxel accuracy and the capability of detecting subtle local changes in brain anatomical shapes. Surface-based methods have extensive applications in the human brain mapping field, including comparison of 3-D anatomical models across subjects, construction of population-based brain atlases, and detection of group patterns in structural magnetic resonance imaging (MRI) data. Here, we attempt to give an overview of brain Surface-based morphometry algorithms and software, highlighted by some recently developed techniques, such as brain Surface conformal Parameterization, Surface fluid registration, and multivariate statistical measurements.

  • How karst areas amplify or attenuate river flood peaks? A response using a diffusive wave model with lateral flows
    2015
    Co-Authors: Jean-baptiste Charlier, Roger Moussa, Vincent Bailly-comte, Jean-françois Desprats, Bernard Ladouche
    Abstract:

    This paper investigates the role of karst aquifers on flood generation and prop-agation using the Hayami Diffusive Wave (DW) model accounting for uniformly distributed lateral flows. The inverse model was applied on the main channel reaches of the Tarn basin at Millau (2400 km²) in southern France to assess lateral inflows from karstic springs as well as lateral outflows from river losses. Results show that the DW model, which is simple, parsimonious and easy-to-use, is able to quantify lateral flows avoiding difficult Parameterization. Surface/groundwater exchanges were characterized on several reaches along the stream, showing a highly variable attenuation/amplification influence of flood peak by karst units during a single flood event. We showed that the upstream part of the karst area have a dominant attenuation role by re-infiltrating part of runoff from the head-water basin in hard-rock areas, while the downstream part have a dominant amplification role due to high contributions of karst groundwater. These results improved the conceptual hydrogeological model of the Grands Causses region.
