Double sandbar systems are common morphological features along sandy, wave-dominated, micro- to meso-tidal coastlines. Here the AA. use a numerical model to show that the relative importance of self-organization and morphological coupling changes
in favour of the latter with an increase in waterdepth variability along the outer-bar crest. Furthermore, they find that the typical alongshore variability in inner-bar rip-channel scale is indicative of a mixture of self-organization and morphological
coupling rather than self-organization alone. Morphological coupling may thus be more important to understanding and predicting the evolution of inner-bar rip channels than previously envisaged.
The implications of coupling relate to downstream channel response, fan morphology, sedimentation patterns and vertical sedimentary sequences. Temporal and spatial scales of coupling are related, and with increasing scales the dominant controls

Dating Quaternary fault scarps formed in alluvium using morphologic parameters
Ages of fault scarps, as well as those other types of transport-limited slopes, can be estimated by comparing their morphology with the morphology of scarps of known age. Age estimates are derived by fitting the scarp profiles to synthetic profiles
generated using a diffusion equation or, alternatively, by classification using a linear discriminant function. The usefulness of morphology-derived age estimates depends on the relative importance of non-age-related morphologic variation. Data from more
than 200 scarp profiles demonstrate that morphologic variation not related to scarp age can introduce significant uncertainties into morphology-derived age estimates.
Morphology and development of an alluvial fan in a permafrost region, Aklavik Range, Canada
The objectives of this study are to describe the morphology and sedimentology of an alluvial fan, the Mount Goodenough North fan, in a permafrost region; and to interpret the processes responsible for the development of the fan, using both direct
observations and inferences from fan morphology and sedimentology.
The morphological development of the Wadden Sea Island of Jordsand since the storm surges in 1976
Jordsand is the smallest island in the Danish Wadden Sea. In this paper a brief statement of the morphological development of the island is given for the period 1976-88. Furthermore, the development of two adjacent morphological elements, the high
A Kozép-békési varosok funkcionalis morfologiai elemzésének altalanosithato tapasztalatai. (Experience to be generalized from the functional-morphological analysis of the mid-Békés towns)
The data basis for functional-morphological analyses has considerably broadened (census statistics, etc.). The positions of the mid-Békés towns in the settlement network have changed. Functions modified at a more rapid rate than morphology. (DLO).
