Spatial and Temporal Variability of Grain Size and Small-Scale Mophology

Abstract

We will test the hypothesis that heterogeneity of coastal subaerial and subaqueous morphology on many scales is correlated with heterogeneity in surface sediments, which influences the morphodynamic feedback. The specific objectives of this work are to: (1) develop and integrate a suite of sensors for efficiently measuring surf zone morphodynamics and hydrodynamics, in particular surface sediment grain size distribution within the surf zone, (2) obtain, modify, and evaluate an amphibious surf zone crawler as a platform for nearshore observations, (3) test the sensors in the field and obtain measurements of the temporal and spatial variability of sediments and bedforms (4) investigate heterogeneity of morphology in the context of the local sedimentological and hydrodynamic conditions.
