About

Prof. Harshinie Karunarathna is a personal chair in the Zienkiewicz Centre for Computational Engineering at the Department of Engineering of Swansea University, UK. She completed an BSc (Eng) in Civil Engineering at the University of Moratuwa, Sri Lanka, an MSc in River Estuarine and Coastal Engineering at Imperial College, London and a PhD in Coastal Engineering at Saitama University, Japan. Her primary discipline of research and teaching is coastal and estuarine engineering. Her main research focus is coastal hydro-morphodynamics and climate change impacts on the coastal zone. Her research has been supported by Research Councils UK and numerous other funding sources. She has published over 170 research articles in high impact international journals and peer-reviewed conference proceedings and supervised 14 PhD students to successful completion. Harshinie currently leads the Energy and Environment Research group of the College of Engineering.

Taught Modules

EG-M107 Coastal Processes and Engineering

This module provides an introduction to the subject of coastal engineering. It provides an overview of the main physical processes that shape the coastal environment and the wider context of coastal engineering, together with the underlying tidal theory, wave transformation methods and sediment transport concepts. The programme will consist of a series of lectures and examples classes.
EG-M35 Flood Risk Management

Recent years have seen an increasingly volatile climate and hence severe floods across the UK and worldwide, which also accompanies with a constant demand for expertise and know-hows for flood risk management. We intend to use this module to facilitate civil and environmental engineering students with necessary engineering skills and techniques for flood risk management with special focuses on current practice and national polices related and climate change impact and sustainability issues. Any student wanting to pursue or develop in a related career, e.g., water managers, consultancy in flood risk management is encouraged to take the module.
EGA117 Fluid Mechanics I

The module provides an introduction to the methods that can be employed by engineers for the analysis of basic problems involving stationary and flowing fluids. The module contains a theoretical part (delivered in lectures) and a practical component (comprising a set of laboratory experiments). The practical part aims to consolidate the understanding of fluid mechanics in civil engineering.
EGA331 Coastal processes and engineering

This module introduces the fundamentals of wave and tidal mechanics including linear wave theory, wave transformation, nearshore processes, theory of tides and coastal water level variations which are essential to coastal engineering. The concepts introduced here provide an overview of the main physical processes that shape the coastal environment and forms the basis of learning more complex coastal zone management, coastal zone processes modelling and coastal designs in Level M.
