Research overview

My research interests lie in the fields of hydrology, hydraulics and process geomorphology. I am especially interested in the interaction of near-surface flows with the Earth’s surface. Specifically, my current research is focussed on two main areas: (i) parameterisation of the surface roughness of complex topographies across a wide range of process environments and (ii) coupling basic hydrological models with models of malaria transmission. Underlining both these research threads is an appreciation of the structural and functional connectivity of patterns and processes within hydrology and geomorphology at various scales with the aim of invoking this analytical concept to understand nonlinearities and thresholds within water and sediment transfer systems.

I am currently involved with the NERC HYDROMAL project, investigating hydrological and geomorphological drivers of malaria transmission in the Kilombero Valley of Tanzania (NE/H022740/1) (Co-I).

Further Details

My research interests can be divided into two main themes:

(i) Parameterising the surface roughness of complex topographies. Specific areas of research include:

  • development of through-water terrestrial laser scanning (TLS) techniques to facilitate the three-dimensional high-resolution acquisition of submerged topography in shallow gravel-bed rivers;
  • examination of interactions between flow resistance, turbulence intensity, surface form, sediment transport and the dynamics of in-stream invertebrate refugia (both low and high flows) at plot and reach scales in marginally-inundated gravel-bed rivers;
  • incorporation of flow resistance−surface roughness relationships into hillslope hydrological models capable of analysing the interactions between overland flow resistance, infiltration and rainfall patterns on flood generation. This enables a quantitative representation of functional hydrological connectivity, regarded as a fundamental concept in semi-arid hydrology;
  • examining fine scale topographic structures of both glacier ice surfaces and deglaciated terrain;
  • monitoring the fine-scale transformation of surface form over eroding surfaces, including the BSG-funded BadlandScan II project. This research combines repeat TLS monitoring and Structure-from-Motion surveys of a large-scale badland system (Cinca catchment, NW Spain) to inform landscape evolution models.

(ii)    Understanding the dynamic hydrological drivers of malaria transmission. Specific areas of research include:

  • understanding the hydrological processes driving malaria transmission, especially focussing on the maintenance of dry-season refugia for mosquito larvae;
  • developing a hydrological and geomorphological context for observed mosquito dry-season refugia in the Kilombero valley (south Tanzania). This unique environmental approach aims to provide a dynamic malaria hazard map for the valley, but also offers the potential to target remediation activities to the greatest effect;
  • monitoring and modelling hydrological processes in large tropical catchments. Such areas are often ungauged and we know very little about the specific hydrological processes operating. This research aims to provide and interrogate an extensive dataset on the surface and subsurface hydrology of the Namwala subcatchment of the Kilombero River.

I'm also associated with two further research projects:

  • MorphSed: investigating the morpho-sedimentary dynamics of human-stressed fluvial systems and implications for ecological diversity on the Upper Cinca River, Cataluña (co-ordinated by Dr Damia Vericat, University of Lleida);
  • ReesScan: using high-resolution surveys to assess morphological changes in response to multiple flood events across a large reach of the braided Rees River, south Island New Zealand (co-ordinated by Dr James Brasington, Queen Mary)
