  • Visualization of the numerical domain

    Visualization of the numerical domain

    Visualization of the numerical domain. (a) The extent of the domain, the particles, and the fluid velocity on two side edges of the domain. (b)The grid and particles.

  • Narsap Sermia drainage plume

    Narsap Sermia drainage plume

    Narsap Sermia drainage plume observed on 9 September 2009 at the end stage of an ice-dammed lake drainage event. Subsurface sediment-loaded water is seen in the foreground just below a thin transparent surface layer.

  • The unadjusted Tropical Rain Measuring Mission (TRMM) and adjusted mean annual precipitation (MAP) rate for each elevation class within each basin

    The unadjusted Tropical Rain Measuring Mission (TRMM) and adjusted mean annual precipitation (MAP) rate for each elevation class within each basin

    The unadjusted Tropical Rain Measuring Mission (TRMM) and adjusted mean annual precipitation (MAP) rate for each elevation class within each basin. Note that the adjusted (adj.) MAP values at the lower elevations are likely overestimates. Also note that the color scales vary between basins: (a) Marañón, (b) Huallaga, (c) Ucayali, (d) Madre de Dios, and (e) Beni.

  • Lidar-derived gradient map of Harvey and Franklin watersheds with close ups of Harvey and Franklin catchments

    Lidar-derived gradient map of Harvey and Franklin watersheds with close ups of Harvey and Franklin catchments

    (a) Lidar-derived gradient map of Harvey and Franklin watersheds with individual study catchments identified for Harvey watershed in green and with H identifiers and for Franklin watershed in blue with F identifiers. Resistant rock beds are defined as having a gradient > 1 (100%) and are delineated by red tones on the map. Approximate location of anticline axis is described by thin curved line bisecting Franklin watershed from NW to SSE. Inset map delineates the extent of the Tyee Formation in tan and the general extent of resistant beds in blue, and a closed circle marks the study area location. (b) Close-up of Harvey catchments, including H1 catchment outlined in green on the gradient map. Note the topography, with catchments of uniform size and shapes with well-ordered drainage networks. (c) Close-up of Franklin catchments, including the F1 catchment outlined in blue on the gradient map. Note the disorganized topography, with low-gradient basins perched above the red bands defining resistant rock beds, varied sized and shaped catchments, and variable valley density. “Typical” Tyee bedrock underlies the soil-mantled basins perched above the resistant rock beds.

  • Land surface characteristics of the central Andes

    Land surface characteristics of the central Andes

    Land surface characteristics of the central Andes. (a) Percent vegetation cover and (b) modal vegetation type averaged from 0.05° resolution MODIS plant function type data set [Lawrence and Chase, ]. (c) Dominant bedrock lithology from USGS geologic maps [Schenk et al., ]. Only grid cells with an average elevation of >600 m and that were less than 40% glaciated at the LGM are shown. Regions described in the main text are indicated as WF, western flanks; AL, Altiplano; and EF, eastern flanks. Altiplano lakes (Titicaca and Poopó) are outlined in black for spatial reference.
