Infiltration in Unsaturated Layered Fluvial Deposits at Rio Bravo: Photo Essay and Data Summary

摘要: An infiltration and dye transport experiment was conducted to visualize flow processes in a heterogeneous, layered, sandy-gravelly fluvial deposit adjacent Rio Bravo Boulevard Albuquerque, NM. Water containing red followed by blue-green ponded small horizontal zone ({approx}0.5 m x 0.5 m) above vertical outcrop ({approx}4 2.5 m). The lagged behind the wetting front due slight adsorption thus allowing both fronts be observed time at face. After infiltration, slices were excavated midpoint of infiltrometer exposing distribution quasi three-dimensional manner. At small-scale, advancement influenced multitude local capillary barriers within deposit. However scale experiment, appeared smooth with significant lateral spreading {approx} twice that vertical, indicating strong anisotropy pronounced layering. exhibited appreciably more irregularity than front, as well influence preferential features (a fracture) moved directly bypassing fresh water between.
