Aeolian sediment transport pathways and aerodynamics at troughs on Mars
BOURKE, MARY (2004)Interaction between wind regimes and topography can give rise to complex suites of aeolian landforms. This paper considers aeolian sediment associated with troughs on Mars and identifies a wider range of deposit types ... -
Channel adjustment to extreme floods in arid central Australia.
BOURKE, MARY (New Zealand Geographical Society, 1998) -
Cyclical construction and destruction of flood dominated floodplains in semiarid central Australia
BOURKE, MARY (1994)The morphostratigraphy of flood plains along unconfined reaches of the Todd River, central Australia, indicate that flood plain formation is dominated by high magnitude floods. Processes of flood plain destruction include ... -
The dune effect on sand-transporting winds on Mars
BOURKE, MARY (2015)Wind on Mars is a significant agent of contemporary surface change, yet the absence of in situ meteorological data hampers the understanding of surface-atmospheric interactions. Airflow models at length scales relevant to ... -
Dynamic river channel suggests a long-lived Noachian crater lake on Mars.
BOURKE, MARY (2005)ecent images of the Noachian-age Holden Northeast Crater show spectacular meandering channels that form a complex 150 meter thick lacustrine river delta deposit confined to the northwest margin of the crater. We ... -
Dynamics of unusual debris flows on Martian sand dunes
BOURKE, MARY (2004)Gullies that dissect sand dunes in Russell impact crater often display debris flow-like deposits in their distal reaches. The possible range of both the rheological properties and the flow rates are estimated using ... -
An Empirical Approach to Studying Debris Flows - Implications for Planetary Modeling Studies.
BOURKE, MARY (2002)High-resolution images acquired by the Mars Global Survey Mars Orbiter Camera show gullies on the walls of impact craters and valley systems on Mars. Depositional aprons associated with these gullies have been interpreted ... -
Mars global digital dune database and initial science results
BOURKE, MARY (2007)A new Mars Global Digital Dune Database (MGD 3 ) constructed using Thermal Emission Imaging System (THEMIS) infrared (IR) images provides a comprehensive and quantitative view of the geographic distribution of moderate- ... -
Recent aeolian erosion and deposition in the north polar plateau of Mars.
BOURKE, MARY (2007)Background: Planum Boreum, the north polar plateau of Mars, displays four extensive low-albedo regions covered with widespread se dimentary deposits that are thick enough to partly or completely suppress the signature ... -
Recent developments in planetary Aeolian studies and their terrestrial analogs
BOURKE, MARY (2013)This paper summarizes the many advances that have been made in the study of planetary Aeolian processes that have taken place since the first Planetary Dunes Workshop was held in May of 2008, through 2011. Many of the ... -
Varieties of barchan form in the Namib Desert and on Mars
BOURKE, MARY (2009)
