“…There are four main areas of aeolian deposits in this region: 1) sand sheets and small dune fields in the Coachella Valley (Beheiry, 1967;Wasklewicz and Meek, 1995;Griffiths et al, 2002;Katra et al, 2009); 2) the active complex crescentic Algodones Dunes of southeastern California (Sweet et al, 1988;Derickson et al, 2008); 3) source-bordering dunes in the Gila River valley (Wright et al, 2011) and adjacent to the Colorado River (Parker dunes); and 4) the Gran Desierto sand sea of northern Mexico (Blount and Lancaster, 1990;Beveridge et al, 2006;Scheidt et al, 2011). The Colorado River has provided sediment for the Parker and Algodones dunes, and large parts of the Gran Desierto sand sea (Muhs et al, 1995Scheidt et al, 2011).…”

“…The northern Coachella Valley is bounded on the northeast by the Little San Bernardino Mountains and to southwest by the San Jacinto Mountains of the Peninsular Range. These ranges, which reach altitudes in excess of 3050 m, are predominately composed of felsic igneous and metamorphic rock assemblages: granite, granodiorite, quartz diorite, gneiss, and to a lesser extent, gabbro, quartzite, marble, and schist (Wasklewicz and Meek, 1995). During the past three million years, erosion of the ranges has resulted in filling of the basin floor with alluvial, colluvial, and eolian materials.…”

“…Because of the episodic nature of fluvial sediment input into the (Griffiths et al, 2002). Eolian corridors modified after Wasklewicz and Meek (1995). system and the high energy of the wind regime, depletion of upwind sand sources as well as ephemeral eolian landforms is expected.…”

“…Alternatively, periods of desiccation of palaeolakes may provide a major input of sediment to dune systems and (as dust) to desert soils Blum et al, 1997). Understanding the sources of sediment for many dunefields has been advanced by application of modem geochemical and mineralogical techniques to identify (or at least constrain) the sediment source(s) (Muhs et al, 1995;Wasklewicz and Meek, 1995;Muhs et al,1996;Winspear and Pye, 1995;. Information on sand mineralogy and colour derived from remote-sensing images can then be used to assess how this sediment has moved through the dunefield (Ramsey et al, 1993;Walden et al, 1996).…”

The past year has been one in which the subfield of the geomorphology of aeolian processes and landforms has finally matured. There have been two important books: one is a general text on aeolian landforms , which should make the field much more widely understood and accessible to students; the other is a review of the geomorphology of desert dunes (Lancaster, 1995a). collections of articles on the research frontier and illustrate the diversity of approaches. I Changing paradigms in aeolian process studies Studies of sand transport by wind have traditionally concentrated on wind tunnel experiments in which controlled conditions of airflow and sediment size have allowed precise quantification of relations between transport rates and boundary layer winds. As commented on by Anderson et al. (1991), there is a need to relax these constraints to deal with more realistic conditions of unsteady flow and variable surface conditions so that geological and environmental problems can be addressed. Important aspects of surface conditions include moisture content (Arens, 1996) and vegetation cover (Musick and Trujillo, 1996;Wolfe and Nickling, 1996), both of which act to increase the transport threshold, slope (Iversen and Rasmussen, 1994;Rasmussen et al., 1996) and surface roughness (Greeley et al., 1995). Recent field studies have documented the spatial and temporal variability of actual transport rates in a variety of environments (beaches, simple dunes, agricultural lands and playas). They provide valuable insights into the appropriate methodology and instrumentation surface changes in time and space. The dynamic nature of surface conditions coupled with interactions between the wind, the surface, and the developing saltation cloud give rise to a 'fetch effect' or the change in sediment flux with distance downwind (Gillette et al., 1996). The effects of gustiness and turbulence on sediment transport are now being increasingly recognized (Butterfield, 1993), and instrumentation to detect and measure them is becoming more widely available (Jackson,
