Climate and Rivers (2019)
Journal Article
Over the last few decades as hydrologists have slowly raised their line of sight above the watershed boundary, it has become increasingly recognised that what happens in the atmosphere, as a major source of moisture for the terrestrial branch of the... Read More about Climate and Rivers.
The relationship between drainage density, erosion rate, and hilltop curvature: Implications for sediment transport processes (2016)
Journal Article
Drainage density is a fundamental landscape metric describing the extent of the fluvial network. We compare the relationship between drainage density (Dd) and erosion rate (E) using the Channel‐Hillslope Integrated Landscape Development (CHILD) numer...

A segmentation approach for the reproducible extraction and quantification of knickpoints from river long profiles (2019)
Journal Article
Changes in the steepness of river profiles or abrupt vertical steps (i.e. waterfalls) are thought to be indicative of changes in erosion rates, lithology or other factors that affect landscape evolution. These changes are referred to as knickpoints o... Read More about A segmentation approach for the reproducible extraction and quantification of knickpoints from river long profiles.
Unsupervised detection of salt marsh platforms: a topographic method (2018)
Journal Article
Salt marshes filter pollutants, protect coastlines against storm surges, and sequester carbon, yet are under threat from sea level rise and anthropogenic modification. The sustained existence of the salt marsh ecosystem depends on the topographic evo... Read More about Unsupervised detection of salt marsh platforms: a topographic method.
The dynamics of mountain erosion: cirque growth slows as landscapes age (2019)
Journal Article
Glacial cirques are widely used palaeoenvironmental indicators, and are key to understanding the role of glaciers in shaping mountain topography. However, notable uncertainty persists regarding the rate and timing of cirque erosion. In order to addre... Read More about The dynamics of mountain erosion: cirque growth slows as landscapes age.
Daily bathymetric surveys document how stratigraphy is built and its extreme incompleteness in submarine channels (2019)
Journal Article
Turbidity currents are powerful flows of sediment that pose a hazard to critical seafloor infrastructure and transport globally important amounts of sediment to the deep sea. Due to challenges of direct monitoring, we typically rely on their deposits...

Subglacial hydrological control on flow of an Antarctic Peninsula palaeo-ice stream (2019)
Journal Article
Basal hydrological systems play an important role in controlling the dynamic behaviour of ice streams. Data showing their morphology and relationship to geological substrates beneath modern ice streams are, however, sparse and difficult to collect. W...

Intercomparison of Evapotranspiration Over the Savannah Volta Basin in West Africa Using Remote Sensing Data (2008)
Journal Article
This paper compares evapotranspiration estimates from two complementary satellite sensors – NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and ESA’s ENVISAT Advanced Along-Track Scanning Radiometer (AATSR) over the savannah area of the...

Quantification of node importance in rain gauge network: influence of temporal resolution and rain gauge density (2020)
Journal Article
Rain gauge network is important for collecting rainfall information efectively and efciently. Rain gauge networks have been studied for several decades from a range of hydrological perspectives, where rain gauges with unique or non-repeating informat...

Controls on the geotechnical response of sedimentary rocks to weathering (2019)
Journal Article
Weathering reduces the strength of rocks and so is a key control on the stability of rock slopes. Recent research suggests that the geotechnical response of rocks to weathering varies with ambient stress conditions resulting from overburden loading a...

Controls on the formation of turbidity current channels associated with marine-terminating glaciers and ice sheets (2019)
Journal Article
Submarine channels, and the sediment density flows which form them, act as conduits for the transport of sediment, macro-nutrients, fresher water and organic matter from the coast to the deep sea. These systems are therefore significant pathways for... Read More about Controls on the formation of turbidity current channels associated with marine-terminating glaciers and ice sheets.
The importance of sewage effluent discharge in the export of dissolved organic carbon from United Kingdom rivers (2019)
Journal Article
The flux of fluvial carbon from the terrestrial biosphere to the world's oceans is known to be an important component of the global carbon cycle but within this pathway the flux and return of carbon to the river network via sewage effluent has not be...

Using lake sediment archives to improve understanding of flood magnitude and frequency: recent extreme flooding in northwest UK (2019)
Journal Article
We present the first quantitative reconstruction of palaeofloods using lake sediments for the UK and show that for a large catchment in NW England the cluster of devastating floods from 1990 to present is without precedent in this 558‐year palaeo‐rec...

A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID) (2020)
Journal Article
The paleoclimate community has an interest in distributed subglacial bedrock sampling but, while capable drill systems do exist, they are often incompatible with Twin Otter logistics. To address this issue, a design built on the existing low footprin... Read More about A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID).
Emergent characteristics of rockfall inventories captured at a regional scale (2020)
Journal Article
High-resolution rockfall inventories captured at a regional scale are scarce. This is partly owing to difficulties in measuring the range of possible rockfall volumes with sufficient accuracy and completeness, and at a scale exceeding the influence o...

Carbon dioxide emissions by rock organic carbon oxidation and the net geochemical carbon budget of the Mackenzie River Basin (2019)
Journal Article
The exposure of organic carbon in rocks to oxidative weathering can release carbon dioxide (CO2) to the atmosphere and consume atmospheric oxygen. Alongside volcanism, metamorphism, and the weathering of carbonate minerals by sulfuric acid, this is a...

Flow resistance and hydraulic geometry in bedrock rivers with multiple roughness length scales (2019)
Journal Article
Many models of incision by bedrock rivers predict water depth and shear stress from discharge; conversely, palaeoflood discharge is sometimes reconstructed from flow depth markers in rock gorges. In both cases assumptions are made about flow resistan... Read More about Flow resistance and hydraulic geometry in bedrock rivers with multiple roughness length scales.
Debris-flow volume quantile prediction from catchment morphometry (2019)
Journal Article
Estimation of the volumes of potential future debris flows is a key factor in hazard assessment and mitigation. Worldwide, however, there are few catchments for which detailed volume-frequency information is available. We (1) reconstructed volume-fre...

An integrated process‐based model of flutes and tool marks in deep‐water environments: Implications for palaeohydraulics, the Bouma sequence and hybrid event beds (2020)
Journal Article
Flutes and tool marks are commonly observed sedimentary structures on the bases of sandstones in deep‐water successions. These sole structures are universally used as palaeocurrent indicators but, in sharp contrast to most sedimentary structures, the...
