Previous research

'Large woody debris- a river restoration panacea for streambed nitrate attenuation?'  2014- present

A NERC- funded project to determine the efficiency of alternative (permanent and transient) instream wood restoration designs for the management of biogeochemical cycling and nutrient uptake in the hyporheic zone of lowland rivers. The outcomes of this project will directly impact river restoration management and policy and decide whether, and to what degree, instream wood restoration can be deployed in lowland steams to reduce critically high nitrogen loads.  Collaborators: University of Birmingham and Queen Mary University, London

‘Rapid Assessment of Physical Habitat Sensitivity to Abstraction’ 2013-2014
An Environment Agency/ University of Worcester funded position which sought to develop and improve the operational capacity of the Environment Agency (EA) to measure and monitor the sensitivity or rivers to river and groundwater abstractions.  A major outcome of the project was the further development and refinement of the RAPHSA (Rapid Assessment of Physical Habitat Sensitivity to Abstractions) tool which allows the EA to determine which rivers are more or less sensitive to water abstractions, and thus provide a secure foundation for the future licensing of river and groundwater abstractions within England.
Collaborators: Environment Agency, University of Worcester, Centre for Ecology and Hydrology

NERC Policy Placement Fellow ‘Understanding the impacts of water abstraction and river flows on aquatic ecology’ 2011-2013
In conjunction with the Environment Agency.  This research aimed to enhance the hydroecological evidence base used by the EA to assess and regulate abstraction pressures throughout England and Wales.  Key activities included development and verification of the current method used by the EA to assess ecological consequences of abstraction pressure and the analysis of novel techniques and tools which may be used to support operational decisions.
Collaborators: Natural Environment Research Council, Environment Agency, University of Birmingham

‘Evolution of NITrogen BUFFERing capacity of land water interfaces along hydrosystems of different age (NITBUFFER)  2010-2011
This NERC funded project sought to analyse the relationship between landscape formation and nitrogen cycling processes in order to provide quantitative data on the consequences of climate change and associated deglaciation on nitrogen fluxes.  By using data obtained from remote sensing using LiDAR and satellite (Landsat) data, twinned with the measurement of rate processes involved in nitrogen cycling within different land- water interfaces, this research provided the first insights into the natural timeframe of land- water interface formation and development, and their consequences on nitrogen regulation in stream channels.

‘The development of geomorphic and hydraulic complexity and its influence on fish communities following glacial recession in Glacier Bay, Alaska’  2006-2009
Rapid glacial recession within Glacier Bay National Park, Alaska, has resulted in the unique opportunity to study the formation and development of stream communities within watershed of different ages in a relatively small spatial scale. Utilising this opportunity, it is possible to monitor geomorphological development and associated ecological responses over time. The project aim was to assess the characteristics of bed morphology and hydraulics, and the influence of instream wood in determining the availability of instream habitat for Pacific salmon as they continue to colonise the developing habitats.
Collaborators: Prof. A. Milner, Dr I. Maddock (University of Worcester)

‘Sustainable bank protection strategies: A best practice guide’  2008
ESPRC KTA program focusing the production of best practice guidelines for the sustainable management of bank erosion in large tropical river systems. Outputs of this work, including a critical review of bank protection methods, have the potential to be employed to stabilise eroding sites along the banks of large monsoonal rivers in developing nations such as Vietnam, Cambodia, Laos and Bangladesh.
Collaborators: Prof. S. Darby and Prof. P. Carling (Southampton University)
