I am a Senior Lecturer and the director of Post-Graduate study Taught (PGT) at Cardiff School of Engineering. I have about 15 years experience in developing and refining hydro-environmental computational models to investigate hydrodynamic, flood modelling as well as simulating water quality and sediment transport processes. I am also a member of the leadership team of the International Association for Hydro-environment engineering and Research (IAHR) UK chapter.

I graduated from Amirkabir University of Technology - Tehran Polytechnic (Iran), with a BSc in Civil Engineering in 2001 and an MSc in Water Engineering in 2005. I also worked as a civil engineering at different levels, before I started my PhD including during my under graduate and masters studies.

My PhD research was focused on improving various 1D and 2D hydro-environmental numerical models through enhancement of boundary conditions, increasing model efficiency, linking model applications compliance with OpenMI standard, development of a user-friendly graphical user interface and incorporating numerical models into a GIS software beside refinements of models using laboratory data. Through a Halcrow (now CH2M) studentship, I was also in development of ISIS 2D and linking of the model to ISIS 1D (both are components of Flood Modeller Pro now).

I worked as research associate at Cardiff University from Feb 2010 to Sep 2013, working on two different projects simultaneously. One of the projects involved developing hydro-environmental models to predict water quality at a pilot site, namely Swansea Bay, and providing a better understanding of pollution sources, to assist with maintaining UK’s Blue Flag beaches by meeting the new EU Bathing Water Directive. The other project involved developing hydro-environmental models to simulate the hydro-environmental impacts of various marine renewable energy schemes, including tidal stream turbines and tidal range schemes, such as tidal lagoons and barrages.

My research is mainly focused on hydro-environmental modelling motivated by reducing the risk to humans’ health and sustainable use of water. Three key strands of my research are as follows:

  • Flood modelling with particular focus on modelling rapids floods, dynamic 1D-2D linking during flood events, modelling flood risk and flood hazard and implementation of Natural Flood Management.
  • Water quality and sediment transport modelling particularly faecal bacteria modelling including interaction with sediment, dynamic decay rate and monitoring approaches for both bathing water and aquaculture sites.
  • Marine renewable energy including tidal stream and tidal range schemes.
