The spatial variabi]Lity and co-variability of two different types of remote sensing derivatives that portray vegetation and geomorphic patterns are analyzed in the context of estimating regional-scale CO 2 flux from land surfaces in the arctic tundra. For a study area encompassing the Kuparuk River watershed of the North Slope of Alaska, we compare satellite-derived maps of the normalized diff...

Relationships between cataclysmic flood-generated landforms and flood hydraulics were investigated along Box Canyon, an 11 km long bedrock gorge of the lower Big Lost River. Geomorphic mapping along Box Canyon indicates that a cataclysmic flood completely inundated the gorge, resulting in large-scale erosional and depositional features on the adjacent basalt upland. Step-backwater hydraulic mod...

in recent years there has been studies concerning the investigation of macro-scale geomorphic proxies of quaternary climatic changes in the study area. without detail analysis of slope geomorphic features, there can be little progress on expanding the knowledge of past slope development in the northwestern iran high mountain environments. consequently, the information pertaining to these quater...

Reconstructing paleoenvironmental change from glacial geologic evidence in the Himalayas has been difficult because of the lack of organic material for radiocarbon dating and the problems of correctly identifying the origin of highly dissected landforms. Studies of the contemporary glacial depositional environments, and ancient landforms and sediments in the Hunza valley (Karakoram Mountains), ...

We present the first extensive high-resolution glacial geomorphic map west of Andean Cordillera in southernmost Chile (52.8–53.1°S, 73.0–73.9°W). The extends over 1565 km2 and is based on satellite images aerial photographs. At selected locations, remotely mapped geomorphology was corroborated by field observations. study area dominated erosional landforms (77%) depositional (23%), with publish...

Significant advances have been made towards understanding the dynamics of geomorphic systems through the development of new concepts. In the last two decades, these developments were partly guided by the change in the scale of geomorphic analysis from local (landform) to regional (landscape) scale and partly due to the emergence of new scientific tools and quantitative models. The process-based...

Recent research has shown that the Faynan Orefield was a scene of intensive metal production during Classical Period, but infrastructure supporting this activity is less well known. We present evidence for previously undetected floodwater-farming and quarrying, which contributed to economic life complex times. The site located on an ancient route, south main orefield. describe hydrological cont...

Several glacier-like landforms have been identified on Mars. We can view some of them with Google Earth and its virtual Mars planet. In the images of Ismeniae Fossae glaciers, the flow lines of these landforms are clearly visible too.
