Construction, destruction and fan‐river coupling dynamics during two consecutive debris flow events in an arid fluvial system

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 4, 30 March 2025.
Debris flows into tributary‐junction alluvial fans contributing to both their formation and destruction. In northern Chile, we estimated the geomorphic changes caused by two consecutive debris flow events and analysed differences in debris flow sedimentology between them.

Unicellular maps and filtrations of the mapping class group [PDF]

open access: yesarXiv, 2020
This article first answers to questions about connectedness of a new family of graphs on unicellular maps. Answering these questions goes through a description of the mapping class group as surgeries on unicellular maps. We also show how unicellular maps encode subgroups of the mapping group and provide filtrations of the mapping class group.

Reading the Regolith: Mapping the Landscape and Developing an Understanding of the Contribution of Soil Biota to Regolith Formation in Northern Australia

open access: yes, 2006
The Tanami region of northern Australia is highly prospective for mineral exploration, however exploration has been hampered by the extensive development of regolith.

James Buttle Review: The Characteristics of Baseflow Resilience Across Diverse Ecohydrological Terrains

open access: yesHydrological Processes, Volume 39, Issue 3, March 2025.
Dynamic storage of groundwater drains to streams via permeable geologic pathways. Land surface processes, source groundwater characteristics, and the spatial distribution of groundwater drainage areas across stream networks influence stream baseflow resilience at nested scales.

The Influence of Topography on the Global Terrestrial Water Cycle

open access: yesReviews of Geophysics, Volume 63, Issue 1, March 2025.
Abstract Topography affects the distribution and movement of water on Earth, yet new insights about topographic controls continue to surprise us and exciting puzzles remain. Here we combine literature review and data synthesis to explore the influence of topography on the global terrestrial water cycle, from the atmosphere down to the groundwater ...

Parameterization-Independent Importance Sampling of Environment Maps [PDF]

open access: yesarXiv, 2022
Environment maps with high dynamic range lighting, such as daylight sky maps, require importance sampling to keep the balance between noise and number of samples per pixel manageable. Typically, importance sampling schemes for environment maps are based directly on the map parameterization, e.g.

Tilt Map: Interactive Transitions Between Choropleth Map, Prism Map and Bar Chart in Immersive Environments [PDF]

open access: yes, 2020
We introduce Tilt Map, a novel interaction technique for intuitively transitioning between 2D and 3D map visualisations in immersive environments. Our focus is visualising data associated with areal features on maps, for example, population density by state.

Constraining Erosion Rates and Landscape Evolution With In Situ 10Be and 26Al Cosmogenic Nuclides at Table Mountain, Antarctica

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 3, March 2025.
Abstract This study investigates surface weathering and sediment preservation at Table Mountain, a high‐elevation, hyperarid, polar landscape in the Transantarctic Mountains. We report cosmogenic nuclide concentrations (10Be and 26Al) in quartz from bedrock surfaces, erratic boulder lag, and cobbles embedded within Sirius Group sediments to quantify ...

Monitoring and Modeling the Soil‐Plant System Toward Understanding Soil Health

open access: yesReviews of Geophysics, Volume 63, Issue 1, March 2025.
Abstract The soil health assessment has evolved from focusing primarily on agricultural productivity to an integrated evaluation of soil biota and biotic processes that impact soil properties. Consequently, soil health assessment has shifted from a predominantly physicochemical approach to incorporating ecological, biological and molecular microbiology

Discrete mappings with an explicit discrete Lyapunov function related to integrable mappings [PDF]

open access: yes, 2006
We propose discrete mappings of second order that have a discrete analogue of Lyapunov function. The mappings are extensions of the integrable Quispel-Roberts-Thompson (QRT) mapping, and a discrete Lyapunov function of the mappings is identical to an explicit conserved quantity of the QRT mapping.
