Hassan is a river scientist interested in how catchments shape the quality of water that flows from land to sea, and how long-term monitoring records can be used to understand environmental change. His research draws together hydrology, water quality, and environmental data science to inform the sustainable management of rivers, estuaries, and coastal waters.
His current PhD work examines long-term nutrient dynamics and load estimation across UK coast-draining catchments, contributing to the evidence base for the UK Marine Strategy (UKMS) and OSPAR Riverine Inputs and Direct Discharges (RID) frameworks. Beyond his doctoral research, his interests span catchment science more broadly, from fluvial geomorphology and hydrological processes to river water quality and pollutant transport.

My research sits within river and catchment science, with interests spanning fluvial geomorphology, hydrological processes, and water quality. I am drawn to questions about how catchments function as integrated physical and biogeochemical systems, and how this understanding can be built from long-term monitoring records.
Current work focuses on the physical and chemical controls on river water quality, and the catchment-scale processes that regulate the transport of pollutants from land to sea. I am particularly interested in:

• catchment characterisation and typologies based on hydrological, geological, and land-use controls;
• the information content and structural biases of long-term water quality monitoring networks;
• nutrient load estimation across gauged and ungauged catchments; and
• the implications of riverine nutrient inputs for coastal eutrophication and ecosystem health.

Hassan holds a BSc in Civil Engineering from the University of Khartoum and an MSc in Civil Engineering from the University of Nottingham (2017). He began his career in structural engineering before shifting towards water environments, completing a second MSc in Sustainable Water Environments at the University of Glasgow (2023), where he developed his research focus as a river scientist. Before starting his PhD at UEA, he worked as a Wastewater Hydraulic Modeller at AtkinsRéalis.
