maps and photo - Abrupt cut of drainages when reaching loose materials (e.g., sands) as revealed on a geologic map; the same location in the map is shown in the attached photo

annotated image maps - The images above show the current drainages existed on SRTM DEM; while the image below is a processed ALOS PALSAR image showing traces of delta-like shape paleodrainages (DPl); but they do not coincide with the current drainages in the SRTM DEM (image above). Triangle at point S1 is the site where the stratigraphic sequence was investigated.

photo - sand meets the rock outcrops, Hafar Al Batin desert

annotated image maps - he image above shows a shaded figure for an odd paleodrainage (OPl) as shown on the processed ASTER image. The same ASTER image was used below after projecting the current drainages extracted from STRM DEM. There is no coincidence between the OPl and the current drainages evidencing an invisible paleodrainage (OPl). Triangle at point S2 is the site where the stratigraphic sequence was investigated

map - A total of 78 catchments having recorded SGF/SFF historical events with assigned ID number.

(b) Schematization of cross section, longitudinal section and plan view of levee deposit. (c) Schematization of clasts’ orientation and size distribution in longitudinal section view. (d) Statistical distribution of clasts’ (>20 cm) intermediate axis (b) orientation from up to down slope.

Food for thought #Samples from higher #paleolatitudes were on average smaller, but contained #outliers with the largest #sizes, highlighting the need to analyze entire #distributions. #Lithology and #collection differences need to be accounted for when evaluating #size differences across #space (#polar #gigantism) and #time (#Lilliput #effect). Similarly, differences in #facies may affect #species #determination

Multivariate dispersion of size distributions based on Kolmogorov distances between them, according to sampling factors affecting their shapes (n = 33). A) By genus. B) By lithology. C) By collection style.

The #effects are then compared with effects on #mean #sizes. In all #analyses, #lithology was the #dominant effect, with sizes #greater by 59% in #marls and by 33% in #limestones, as compared to #black #shales. The effect of complete #sampling style was a #decrease in size by 11%.
