Regional landform thresholds [PDF]

open access: yes
Remote sensing technology allows us to recognize manifestations of regional thresholds, especially in the spatial characteristics of process agents. For example, a change in river channel pattern over a short distance reflects a threshold alteration in ...

New Archaeological Investigations at the M. S. Roberts Site (41HE8) in the Caddo Creek Valley in Henderson County, Texas [PDF]

open access: yes, 2016
In this article, we discuss new archaeological investigations at the M. S. Roberts site (41HE8), likely a 14th to early 15th century A.D. Caddo period mound center along Caddo Creek in the upper Neches River basin in Henderson County in East Texas.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

The Wa\u27akas Site (41CP490) at Lake Bob Sandlin, Camp County, Texas [PDF]

open access: yes, 2012
The Wa\u27akas site (meaning Cow in the Caddo language) is located on a small toe slope (330ft. amsl) overlooking a small and unnamed tributary to Big Cypress Creek. The channel of Big Cypress Creek lies about 1 km to the north. The toe slope landform is

Asynchronous glacier dynamics during the Antarctic Cold Reversal in central Patagonia [PDF]

open access: yes, 2018
We present 14 new 10Be cosmogenic nuclide exposure ages quantifying asynchronous readvances during the Antarctic Cold Reversal from glaciers in the Baker Valley region of central Patagonia.

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

An Ontology for Submarine Feature Representation on Charts [PDF]

open access: yes, 2013
A landform is a subjective individuation of a part of a terrain. Landform recognition is a difficult task because its definition usually relies on a qualitative and fuzzy description.

Accuracy Assessment and Comparative Analysis of IDW, Spline and Kriging in Spatial Interpolation of Landform (Topography): An Experimental Study

open access: yes, 2017
It is practically impossible and unnecessary to obtain spatial-temporal information of any given continuous phenomenon at every point within a given geographic area.

Hierarchically nested river landform sequences. Part 2: Bankfull channel morphodynamics governed by valley nesting structure

open access: yesEarth Surface Processes and Landforms, 2018
River corridors exhibit landforms nested within landforms repeatedly down spatial scales. In Pasternack et al. ( ), a new, scale‐independent, hierarchical river classification was developed that uses five landform types to map the domains of a single ...

Geospatial technology based evaluation of recent morphodynamic changes and flow patterns in the upper Jhelum River

open access: yesRiver, EarlyView.
Abstract This study was conducted to address the concerns over the changes in river morphology and their implications for sustainable river management. It investigates the morphological dynamics of the Upper Jhelum River between 2018 and 2023, using high‐resolution Sentinel‐2 imagery and advanced geospatial techniques to capture subtle yet significant ...
