Infiltration Dynamics on Early Mars: Geomorphic, Climatic, and Water Storage Implications

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract On early Mars, the integration of surface, groundwater, and climate systems into an integrated hydrological system remains poorly understood. The partitioning of precipitation, between surface and groundwater via infiltration, controls the Martian aquifer recharge rates and, subsequently, surface erosion processes.

Distribution and palaeoenvironmental significance of mountain blockstreams in the southern hemisphere

open access: yesJournal of Quaternary Science, Volume 40, Issue 3, Page 537-557, April 2025.
ABSTRACT Openwork mountain block deposits (blockfields, blockstreams) have received much research interest globally given their visual appeal as prominent cold‐region landforms. However, studies have shown that these landforms in both glaciated and non‐glaciated environments are probably of considerable age (pre‐Quaternary), yet the environmental ...

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.

The Geoarchaeology of Agricultural Terraces in Europe: Construction, Resilience and Implications for Sediment Delivery

open access: yesGeoarchaeology, Volume 40, Issue 2, March/April 2025.
ABSTRACT Although the primary purpose of agricultural terracing can be assumed to be food production, it has been suggested that a secondary purpose was the control of soil erosion. In this paper, we explore this thesis with multi‐proxy data from the TerrACE project, which studied 20 sites in a latitudinal transect across Europe.

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.

Aspects of the geomorphology of the Greywacke Ranges bordering the Lower and Middle Waikato Basins [PDF]

open access: yes, 1967
The fault-bounded blocks which make up the Greywacke Ranges bordering the Lower and Middle Waikato Basins have a deep red-weathered regolith and are covered by mantles of volcanic ash which can be used for dating ground surfaces.

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 ...

Ice-rich (periglacial) vs icy (glacial) depressions in the Argyre region, Mars: a proposed cold-climate dichotomy of landforms [PDF]

open access: yes, 2017
On Mars, so-called “scalloped depressions” are widely observed in Utopia Planitia (UP) and Malea Planum (MP). Typically, they are rimless, metres- to decametres-deep, incised sharply, tiered inwardly, polygonised and sometimes pitted.
