Novel observations of surface grain-size distributions are used in combination with intra-wave modeling to examine the processes responsible for the sorting of sediment grains on a relatively steep beach (slope?=?1:7.5). The field observations of the

Grain size on the surface of natural beaches has been observed to vary spatially and temporally with morphology and wave energy. The stratigraphy of the beach at Duck, North Carolina, USA was examined using 36 vibracores (~1-1.5 m long) collected alo

The temporal growth of the envelope of bed motion owing to the migration of bedforms, which can be considered a proxy for maximum object burial depth, is examined using five different data sets. These data sets support the hypothesis that the envelop

The long-term goals of the study are to model and measure bedforms in tidal inlets and river mouths. Specifically, the goals are: 1) to use an existing self-organization model to predict multiple scales of bedform formation, growth and migration in c

Estimates of the heights of large (0.1-0.4 m heights and 1-10 m horizontal lengths) migrating bedforms on a sandy beach made with fixed, single-point altimeters are similar to heights estimated from profiles across the bedforms made with altimeters m

The bottom drag coefficient in the nearshore has been suggested to depend on bottom roughness (bedforms) or alternatively on wave breaking. The hypothesis that bottom drag coefficient depends on bottom roughness is tested with 2 months of field obser

Megaripples in the combined flow environment of the nearshore are proposed to behave like dunes or large ripples in rivers, tidal estuaries, and deserts. Their profile basically is symmetric and thus significantly different from the traditional asymm

Migrating megaripples are bedforms that appear in the surf zone of sandy coasts1. With heights of 0.1–0.5 m and wavelengths of 1–5 m, they are similar in size and shape to small dunes, large ripples, or sand waves. Such sedimentary bedforms have
