Research

Nick’s research focuses on rainfall-runoff processes and nature-based solutions within upland UK & equatorial tropics. 

Runoff pathways are regulated by meteorological & watershed effects and changed by our interventions, sometimes positively in the form of nature-based solutions (NbS). Changes in these hydrological pathways and processes are often key to methods for mitigating water pollution issues, in addition to reducing the risk of floods or droughts.

Current rates of development are giving profound changes to the water cycle (Wohl et al., 2012 Nature Climate Change), but advances in the design of NbS can give positive outcomes for flood mitigation (Chappell and Beven, 2024 Environmental Research Letters) and pollution mitigation (Chappell and Thang 2007 Unasylva).

Quantifying changes in these processes has demanded the use of new field sensor technology (Jones et al., 2014 Environmental Science and Technology) and new modelling approaches (Chappell et al., 2017 Water Research; Beven and Chappell, 2021 WIREs Water; Beven et al., 2022 Hydrological Processes).

Ongoing research projects where Nick is the Principal Investigator at Lancaster include:

• Flood mitigation effectiveness of NFM interventions within the Cumbria Innovative Flood Resilience project ('CiFR-Lancaster’)
• Cumbrian NFM effectiveness monitoring network ('C-NFM’)

• Chief Science Advisor to NERC Flood and Drought Research Infrastructure
• Brampton NFM effectiveness monitoring (‘e-Brampton’)

Recent research projects included:

• Quantifying the likely magnitude of nature-based flood mitigation effects across large catchments ('NERC Q-NFM’)
• Quantifying the benefits of NFM: Equivalent volume metrics (‘eVol-WwNP’)
• Working with natural processes: National opportunity mapping of high runoff soils ('Environment Agency project’)
• Working with natural processes: Life IP Natural flood risk targeting maps ('Rivers Trust project’)
• Regulation of water quality and biodiversity by runoff processes (NERC-BESS ‘DURESS project’)
• Regulation of extreme flood responses by rainfall characteristics associated with particular synoptic climatologies (NERC-CWC ‘Western Ghats’ project)
• Quantifying sensitivity of suspended sediment dynamics to environmental change within Papua New Guinea (‘RamuSED project’)

Nick has a long-term research commitment to catchment monitoring (i.e., the discipline of hydrometry), particularly when combined with numerical modelling, see e.g., the SMART Watershed Network.

Research-led teaching and training

Nick teaches the core Year 1 and Year 2 hydrology courses and a third year field-course based at the Slapton Ley Field Studies Centre (click links to see course pages):

• LEC174 Hydrology: water in the environment
• LEC275 Catchment Hydrology
• LEC370 Hydrological Processes Field-course

These courses are available to the BSc Environmental Science programme, BSc Geography programme, and other programmes in LEC. Nick also teaches undergraduate, masters and PhD research projects in field hydrology and hydrological modelling and is the Director of the MSc Sustainable Water Management and PgCert/PgDip/MSc Flood and Coastal Risk Management, and PgCert Flood Risk Management (Department for Infrastructure) programmes:

• MSc Sustainable Water Management
• PgCert/PgDip/MSc Flood & Coastal Risk Management

Nick is the author of the first eight chapters (focusing on hydrometry) of the latest edition of the hydrology reference text: Shaw EM, Beven KJ, Chappell NA & Lamb R 2011 Hydrology in Practice, Fourth Edition, Taylor & Francis
