Although adding real topography to the models is just one of several steps required to advance in these directions, it is of fundamental importance.…”

On June 29, 2009, version 1 of the ASTER GDEM (Advanced Spaceborne Thermal Emission and Refl ection Radiometer Global Digital Elevation Model) was made available at no cost or restrictions to users worldwide via electronic download. The ASTER GDEM provides expanded spatial coverage and better resolution than other global digital elevation models (DEMs). In this paper we demonstrate how the ASTER GDEM provides new opportunities for investigating large aeolian sand dunes in three-dimensions. Two dune-specifi c spatial analysis methods are presented to illustrate potential applications of these data for discriminating dune generations and quantifying spatial variations of sediment supply. Moreover, we review how existing and emerging fi elds of dune pattern analysis and simulation modeling will be able to make signifi cant advances through application of these data, potentially leading to future progress in studies of dune morphodynamics, environmental controls, and paleoenvironmental reconstructions.

“…3 shows the changes that have occurred in the Western European coastal sand dunes during the last 200 years when naturally mobile dunes were artificially stabilized and came to a stable position at the upper reverse side of the hysteresis curve with maximal vegetation cover. The artificial removal of vegetation on the parabolic dune in North Holland [30], brought the Dutch coastal dunes to a lower stable point of mobility. The coastal dunes of Israel were active and without vegetation because of strong human impact but their vegetation recovered soon after 1949 when the human pressure was curtailed on account of the low wind power on the Israeli coast (Fig.…”

“…In the tropical rainforest of Bukit Tarek Experimental Watershed (BTEW) in Peninsular Malaysia, sediment accumulations were observed along narrow streams after logging, despite the existence of 20-m-wide buffer zones 15,34 double the width dictated in the guidelines. Thus, we examined erosion-accumulation depth, particularly as it relates to microtopography, on varying shaped slopes in 20-m-wide buffer zones to clarify the spatial effects on sediment discharge using the erosion pin method 1,4,29 . We discuss the relationships among the microtopography, physical properties of soils and the effects of vegetation cover, including fallen trees and understory vegetation, on sediment discharge to the streams.…”

To prevent soil runoff from logging roads and skid trails, buffer zones are commonly established along both sides of streams. These buffers range in width from 10 to 100 m from the center of the stream, depending on stream width, (from 1 to > 40 m) as dictated by the Reduced-Impact Logging Guidelines for Lowland and Hill Dipterocarp Forests in Indonesia. In the Bukit Tarek Experimental Watershed in Malaysia, sediment accumulations were observed along narrow streams after logging despite the presence of 20-m-wide buffer zones, double the width set out in the guidelines. Thus, we examined erosion-accumulation depths on different slopes in 20-m-wide buffer zones to clarify the spatial effects on sediment discharge, particularly as it relates to the microtopography and the vegetation cover, including fallen trees. Some of the accumulation depths at lower elevations and along streams were small, whereas on steep concave slopes and hollows that extend to streams, large accumulations were observed 1 year after logging. These findings indicated that, although a 20-m-wide buffer zone may be partly effective at preventing sediment discharge, it is not adequate on concave slopes (lower side-hollows and channel walls) where surface flows often converge. We compared several physical properties of the surface soil in accumulated areas relative to undisturbed areas and demonstrated that bulk density was larger and total porosity and coarse porosity were smaller in the accumulated soils, especially on lower side-hollows. These results indicate that soils accumulated on concave slopes would accelerate the occurrence of surface flow. Tree distribution was not dense in the buffer zones, but fallen trees and the relatively dense understory vegetation including rattans and palms partly prevented the discharge of sediment into streams. Our findings suggested that 20-mwide buffer zones with dense fallen trees and understory vegetation are partly sufficient to prevent sediment discharge; however, along steep concave slopes and hollows where rain water converges, wider and thicker buffer zones are needed.Discipline: Forestry and forest products Additional key words: fallen tree, physical property, soil runoff, vegetation cover
