Overview

Ian D L Foster is affiliated with Rhodes University in South Africa. Their research primarily focuses on environmental science, with significant contributions to agricultural and biological sciences. Their subfields of study include soil science, ecology, water science and technology, atmospheric science, and electrical and electronic engineering.

The main topics of their work cover soil erosion and sediment transport, hydrology and sediment transport processes, hydrology and watershed management studies, geology and paleoclimatology research, soil and water nutrient dynamics, archaeology and ancient environmental studies, and optimal power flow distribution.

Foster has published recent papers addressing various aspects of sediment and environmental monitoring. These include:

  • Sediment source fingerprinting: benchmarking recent outputs, remaining challenges and emerging themes (2020, Journal of Soils and Sediments)
  • Abiotic predictors of fine sediment accumulation in lowland rivers (2021, International Journal of Sediment Research)
  • Comparison of observed and DEM-driven field-to-river routing of flow from eroding fields in an arable lowland catchment (2021, CATENA)
  • Evaluating the performance of taxonomic and trait-based biomonitoring approaches for fine sediment in the UK (2021, Ecological Indicators)
  • Monitoring soil erosion on agricultural land: results and implications for the Rother valley, West Sussex, UK (2020, Earth Surface Processes and Landforms)

Their frequent co-authors include John Boardman, Adrian L. Collins, Kate Rowntree, Simon Pulley, and Yusheng Zhang.

Foster often publishes in specific venues such as Hydrological Processes, Earth Surface Processes and Landforms, Environmental Archaeology, arXiv (Cornell University), and Goldschmidt2021 abstracts.
