Channels in Martian valley networks: Discharge and runoff production

  title={Channels in Martian valley networks: Discharge and runoff production},
  author={Rossman P. Irwin and Robert A. Craddock and Alan D. Howard and Terrence A. Maxwell},
The highland valley networks are perhaps the most compelling evidence for widespread fluvial activity on Mars .3.5 Ga. However, determining the hydrology of these features has been difficult owing to poor image resolution and the lack of available topographic data. New orbital imaging reveals 21 late-stage channels within valley networks, which we use to estimate formative discharges and to evaluate water supply mechanisms. We find that channel width and associated formative discharge are…

Hydrology of early Mars: Valley network incision

Widespread occurrences of valley networks on Mars provide geomorphic evidence for an active hydrologic cycle. To constrain the climatic conditions capable of forming the valley networks, a

Episodic and Declining Fluvial Processes in Southwest Melas Chasma, Valles Marineris, Mars

There is abundant evidence for aqueous processes on Noachian terrains across Mars; however, key questions remain about whether these processes continued into the Hesperian as the martian climate

Evidence for a short period of hydrologic activity in Newton crater, Mars, near the Hesperian‐Amazonian transition

Hesperian/Amazonian‐aged valleys and alluvial fans distributed in regional clusters throughout the southern middle‐ to low‐latitudes were formed during a period of fluvial runoff and erosion which

Megaflooding on Earth and Mars: Large basin overflow floods on Mars

Summary Breaches of large natural basins, usually initiated by high runoff or meltwater production in their contributing watersheds, have been responsible for the most intense recognised terrestrial

An intense terminal epoch of widespread fluvial activity on early Mars: 1. Valley network incision and associated deposits

[1] We present evidence that a final epoch of widespread fluvial erosion and deposition in the cratered highlands during the latest Noachian or early to mid-Hesperian was characterized by integration

Interior channels in Martian valleys: Constraints on fluvial erosion by measurements of the Mars Express High Resolution Stereo Camera

In High Resolution Stereo Camera (HRSC) images of the Mars Express Mission a 130 km long interior channel is identified within a 400 km long valley network system located in the Lybia Montes. Ages of

Characterizing Water on Early Mars through the Geomorphic Analysis, Crater-Age Dating, and Sediment Transport Modeling of Valley Networks and Deltas

The presence of valley networks across much of the ancient surface of Mars, together with the locations and morphologies of the ancient Martian deltas and paleolakes, provides strong evidence that



Groundwater formation of martian valleys

High-resolution images of martian valleys are presented that support the view that ground water played an important role in their formation, although the authors are unable as yet to establish when this occurred.

The case for rainfall on a warm, wet early Mars

[1] Valley networks provide compelling evidence that past geologic processes on Mars were different than those seen today. The generally accepted paradigm is that these features formed from

Drainage basin evolution in Noachian Terra Cimmeria, Mars

[1] Geomorphic mapping of a ∼1 million square kilometer section of Terra Cimmeria on Mars (1:1M scale) indicates that prolonged, intense fluvial erosion occurred during the period of heavy

Drainage basins and channel incision on Mars

Measurements acquired by the Mars Orbiter Laser Altimeter on board the Mars Global Surveyor indicate that large drainage systems on Mars have geomorphic characteristics inconsistent with prolonged

Small Martian valleys: Pristine and degraded morphology

The equatorial heavily cratered uplands of Mars are dissected by two classes of small valleys that are intimately associated in compound networks. Pristine valleys with steep valley walls

Classification and time of formation of Martian channels based on Viking data

Fluviatile and volcanic Martian channels, first discovered on Mariner 9 pictures, have been reexamined by using Viking orbital photography. The superior discrimination of the Viking photographs,

Field surveys of channel width w and drainage area A in bedrock channel reaches reveal relationships where w = cAb, similar to the classic hydraulic geometry of alluvial channels. Data from five
