We present results from geomorphic mapping and visible to near-infrared spectral analyses of the Jezero crater paleolake basin and its associated watershed. The goal of this study is to understand the provenance of the sedimentary deposits within this open-basin lake using a source-to-sink approach. Two fan deposits located within the basin have distinct visible to near-infrared mineralogic sig...

Extended abstract 1- Introduction Soil erosion by water is a dominant geomorphic process which threatens food security in most parts of the world .The geomorphic characteristics of a watershed play an important role in watershed hydrology, soil erosion processes and sediment yield. Geomorphic characteristics can be an indicator of soil erosion and sedimentation of a watershed. Geomorphic char...

in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...

Introduction: The geology of Terby Crater (28S, 287W), located on the northern rim of Hellas impact basin on Mars, is documented through geomorphic and stratigraphic analyses using all currently released visible and thermal infrared image data and topographic information. This large (D=164km), Noachian-aged [1] crater has a suite of geomorphic units [2] and landforms including massive troughs a...

Study area is located in the higher folded belt in the Zagros Mountain in the Iraqi Kurdistan. Analyzed geomorphic indices included sixteen sub basins: the stream gradient index (SL), drainage basin asymmetry (AF), hypsometric integral (Hi), Valley floor width-valley height ratio (VF) and mountain front sinuosity (J) is obtained relative of tectonic activity in the study area. These indices abo...

Article history: Received 9 March 2017 Received in revised form 11 September 2017 Accepted 11 September 2017 Available online xxxx Ecology and geomorphology recognize the dynamic aspects of resistance and resilience. However, formal resilience theory in ecology has tended to deemphasize the geomorphic habitat template. Conversely, landscape sensitivity and state-and-transition models in geomorp...

Marine reserves are becoming progressively more important as anthropogenic impacts continue to increase, but we have little baseline information for most marine environments. In this study, we focus on the Oceanic Shoals Commonwealth Marine Reserve (CMR) in northern Australia, particularly the carbonate banks and terraces of the Sahul Shelf and Van Diemen Rise which have been designated a Key E...

Geomorphic parameters are very helpful as they can quickly explain the concerned area, which is going through a tectonic adjustment. For this purpose, four indices were applied to examine active tectonics in Quetta-Ziarat region. These include: sub-basins asymmetry (Af), transverse topography (T-Factor), hypsometric integral (HI) and stream-length gradient (SL). The calculation of three denoted...
