Hydrological controls on river network connectivity [PDF]

, 2019
This study proposes a probabilistic approach for the quantitative assessment of reach- and network-scale hydrological connectivity as dictated by river flow space–time variability. Spatial dynamics of daily streamflows are estimated based on climatic and

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Quantifying the slip rates, spatial distribution and evolution of active normal faults from geomorphic analysis: Field examples from an oblique-extensional graben, southern Turkey [PDF]

, 2009
Quantifying the extent to which geomorphic features can be used to extract tectonic signals is a key challenge in the Earth Sciences. Here we analyse the drainage patterns, geomorphic impact, and long profiles of bedrock rivers that drain across and ...

Associating Local‐Scale Physical Habitat Assemblages With Reach‐Scale Stream Hydrogeomorphological Types in Mountain Headwater Catchments

River Research and Applications, EarlyView.
ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...

Towards quantifying the relative tectonic activity in the Trans-Yamuna segment of NW Himalaya

Geocarto International, 2023
Owing to the increased availability of high-resolution satellite data and the rapid development of Geographic Information System (GIS) technology, the mapping of active faults and quantification of tectonic activity in inaccessible regions has ...

Long‐Term Effects of Low‐Drop Grade Control Structures on Channel Evolution in the Yazoo River Basin

River Research and Applications, EarlyView.
ABSTRACT Channel incision is a widespread problem, especially in river basins that have an extensive history of channel alterations. Because channel incision causes large ecological and economic consequences, the prevention of continued migration of headcuts, defined as a steep change in stream gradient over a short reach, has been the focus of many ...

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

River Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

Remote sensing and GIS-based analysis of evolving planform morphology of the middle-lower part of the Ganga River, India

Egyptian Journal of Remote Sensing and Space Sciences, 2019
The present work addresses the planform dynamics of the Ganga River in the middle-lower portion over the last six decades and the evolution and transformation of the channel and its floodplain with the help of remote sensing and GIS techniques.
