Computer simulation of the role of groundwater seepage in forming Martian valley networks
(American Geophysical Union, 2008)
The role of groundwater in forming Martian valley networks is simulated in a computer model as seepage erosion by contributing to surface runoff and as seepage weathering by causing accelerated weathering of bedrock, ...
Computer-generated global map of valley networks on Mars
(American Geophysical Union, 2009-11)
The presence of valley networks (VN) on Mars suggests that early Mars was warmer and wetter than present. However, detailed geomorphic analyses of individual networks have not led to a consensus regarding their origin. An ...
Quantifying groundwater-sapping landforms with a hypsometric technique
(American Geophysical Union, 2000)
The groundwater-sapping process generates peculiar landform features, including amphitheater channel head, U-shaped cross section with steep wall and flat floor, and short stubby tributaries. However, previous attempts to ...
Hypsometric Analysis of Margaritifer Sinus and Origin of Valley Networks
(American Geophysical Union, 2002)
The formation of Martian valley networks has been debated since their discovery. The relative roles of groundwater sapping and fluvial runoff processes have different implications on Martian paleoclimate. This paper uses ...
Morphometric Analysis of Martian Valley Network Basins Using a Circularity Function
(American Geophysical Union, 2006)
This paper employs a circularity function to quantify the internal morphology of Martian watershed basins in Margaritifer Sinus region and to infer the primary erosional processes that led to their current geomorphologic ...
