Climate and Hydrogeological Controls on Water Tracks in Permafrost Landscapes

open access: yesReviews of Geophysics, Volume 63, Issue 1, March 2025.
Abstract Climate change drives disturbance in hydrology and geomorphology in terrestrial polar landscapes underlain by permafrost, yet measurements of, and theories to understand, these changes are limited. Water flowing from permafrost hillslopes to channels is often modulated by water tracks, zones of enhanced soil moisture in unchannelized ...

Scoping the suitability of water‐tolerant species of trees for swamp restorations across Australia and its Great Barrier Reef catchment

open access: yesRestoration Ecology, Volume 33, Issue 3, March 2025.
Wetlands are vital for humanity and include some of the most productive, diverse, and service‐rich ecosystems in the world. Service provided include food production (e.g., fish, birds, and vegetables), protection from flooding and storm surge inundation, provision of clean water and climate stability, and timber resources for construction.

Remote Sensing‐Based Ecohydrogeological Characterisation and Perceptual Model of the Bale Mountains, Ethiopia

open access: yesHydrological Processes, Volume 39, Issue 2, February 2025.
Ecohydrogeological processes in tropical volcanic mountains are not well understood. We combined a quantitative water balance analysis in Google Earth Engine with qualitative interpretation of the study area's geologic and geomorphic features.

Hollows on Mercury: Global Classification of Degradation States and Insight Into Hollow Evolution

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract Hollows are small, shallow, irregularly shaped landforms, widespread across Mercury, interpreted to have formed via loss of volatiles. Here, we present the first global analysis of hollow degradation states using a new machine learning‐derived global catalog.

On simple classes of special generic maps and round fold maps and fold maps obtained by composing projections [PDF]

open access: yesarXiv, 2021
Fold maps are fundamental tools in the theory of singularities of differentiable maps and its applications to geometry. They are higher dimensional variants of Morse functions. Classes of special generic maps and round fold maps are important classes of fold maps. {\it Special generic} maps are higher dimensional variants of Morse functions on homotopy

Evaluation of the impact of climate change on rainfall for potential landslide triggering in Japan

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 1, January 2025.
Under the scenario that future greenhouse gas emissions will continue to increase, the projection of precipitation in Japan until 2,100 suggests that intense rainfall with landslide‐triggering potential might increase and occur synchronously in two to five regions owing to more frequent and widespread occurrence of precipitation.

Deep Convolutional Neural Networks for Map-Type Classification [PDF]

open access: yesarXiv, 2018
Maps are an important medium that enable people to comprehensively understand the configuration of cultural activities and natural elements over different times and places. Although massive maps are available in the digital era, how to effectively and accurately access the required map remains a challenge today.

Rebalancing River Lateral Connectivity: An Interdisciplinary Focus for Research and Management

open access: yesWIREs Water, Volume 12, Issue 1, January/February 2025.
Lateral connectivity between waterscapes and adjacent landscapes is critical for river health. We review lateral connectivity across disciplines, reframing lateral connectivity for river science and management. We propose “rebalancing” bidirectional, lateral connectivity as a paradigm to employ when seeking to enhance river ecosystems and climate ...

The Periglacial Landforms and Estimated Subsurface Ice Distribution in the Northern Mid‐Latitude of Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 1, January 2025.
Abstract Subsurface ice in the mid‐latitude regions is a significant water inventory on present‐day Mars, and their volume and distribution are thought to have varied due to the orbitally induced paleoclimatic changes. Using high‐resolution satellite images, the present study explores the distributions of three presumed periglacial landforms (thermal ...

$2^n-$rational maps [PDF]

open access: yesarXiv, 2015
We present a natural extension of the notion of nondegenerate rational maps (quadrirational maps) to arbitrary dimensions. We refer to these maps as $2^n-$rational maps. In this note we construct a rich family of $2^n-$rational maps. These maps by construction are involutions and highly symmetric in the sense that the maps and their companion maps have
