“…Thin soils and steep, complex terrain are also believed to contribute to the generation of small-basin floods in this region (Michaud et al, 2000). In an intensely studied site in northwestern Durango (on the east slope of the SMO), Descroix et al (2002b) found that approximately 85% of hillslope soils exhibited soil depths between 10 and 60 cm.…”

“…Descroix et al (2002b) showed that, at lighter rainfall intensities, soil characteristics become increasingly important. Factors affecting the infiltration of light to moderate precipitation intensity events include hydraulic conductivity, the presence of soil crusts, percent of stone coverage and the structure or layering of soil elements.…”

“…Factors affecting the infiltration of light to moderate precipitation intensity events include hydraulic conductivity, the presence of soil crusts, percent of stone coverage and the structure or layering of soil elements. One of the primary findings of Descroix et al (2002b) was that hydraulic conductivity values were found to be uncorrelated with soil structural and texture data. Their results showed that 70% of the total variability in hydraulic conductivity values calculated within a 400 km 2 area can also be observed within 4 km 2 .…”

“…7). Furthermore, the rainfall-runoff relation between upland areas and the lowland river is weaker as hillslope and channel losses are anticipated to be high in the region (Descroix et al 2002a). This is particularly evident during the field campaign, as denoted by the vertical dashed lines.…”

Variation of Hydrometeorological Conditions along a Topographic Transect in Northwestern Mexico during the North American Monsoon

et al. 2007

Relatively little is currently known about the spatiotemporal variability of land surface conditions during the North American monsoon, in particular for regions of complex topography. As a result, the role played by land-atmosphere interactions in generating convective rainfall over steep terrain and sustaining monsoon conditions is still poorly understood. In this study, the variation of hydrometeorological conditions along a large-scale topographic transect in northwestern Mexico is described. The transect field experiment consisted of daily sampling at 30 sites selected to represent variations in elevation and ecosystem distribution. Simultaneous soil and atmospheric variables were measured during a 2-week period in early August 2004. Transect observations were supplemented by a network of continuous sampling sites used to analyze the regional hydrometeorological conditions prior to and during the field experiment. Results reveal the strong control exerted by topography on the spatial and temporal variability in soil moisture, with distinct landscape regions experiencing different hydrologic regimes. Reduced variations at the plot and transect scale during a drydown period indicate that homogenization of hydrologic conditions occurred over the landscape. Furthermore, atmospheric variables are clearly linked to surface conditions, indicating that heating and moistening of the boundary layer closely follow spatial and temporal changes in hydrologic properties. Land-atmosphere interactions at the basin scale (ϳ100 km 2 ), obtained via a technique accounting for topographic variability, further reveal the role played by the land surface in sustaining high atmospheric moisture conditions, with implications toward rainfall generation during the North American monsoon.

“…Overall, most studies have focused on single SSC attributes. However, infiltration/runoff partitioning are conditioned by a combination of several SSC attributes (Descroix et al, 2001(Descroix et al, , 2002, as taken into account by the H-SSC typology of Andrieux et al (2001).…”
