    • Application of water quality index models to an Irish estuary 

      Uddin, Md Galal; Nash, Stephen; Olbert, Agnieszka Indiana (Civil Engineering Research Association of Ireland (CERAI), 2020-08-27)
      The paper investigates the application of different Water Quality Index (WQI) models for to estuarine waters. WQI models are aggregation based mathematical models that convert extensive water quality data into a single ...
    • Assessment of water quality using Water Quality Index (WQI) models and advanced geostatistical technique 

      Uddin, Md Galal; Olbert, Agnieszka Indiana; Nash, Stephen (Civil Engineering Research Association of Ireland (CERAI), 2020-08-27)
      Water quality index (WQI) models are popular tools to evaluate the quality of water; as such they have been developed and used by many agencies worldwide. However, the WQI model may generate excessive uncertainties in ...
    • Cyclonic circulation in the western Irish Sea in future climate 

      Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (International Association for Hydro-Environment Engineering and Research, 2011-07-01)
      The Irish Sea (IS) is a semi-enclosed body of water on the European Continental Shelf and the Western Irish Sea Gyre (WISG) is a characteristic phenomenon of the Sea. The gyre due to its significant effects on the circulation, ...
    • Interactions, mechanisms and impact of future coastal urban flooding. A case study of Cork city 

      Kirkpatrick, Jennifer Isabel Munro; Nash, Stephen; Hartnett, Michael; Comer, Joanne; Olbert, Agnieszka Indiana (Hydrology Ireland, 2020-11-17)
      In coastal floodplains, high river flows and high coastal water levels can result in extensive flooding. Mechanisms of flooding play a crucial role in flood characteristics with distinctive differences in flood wave ...
    • Mechanisms of flooding in Cork City 

      Olbert, Agnieszka Indiana; Comer, Joanne; Nash, Stephen; Hartnett, Michael (International Association of Hydrological Sciences, 2015-11-17)
      Flooding is one of the most frequent and devastating natural disasters. Many urban developments are located in estuaries where river flow and sea water merge. Cork City situated in the River Lee estuary frequently subject ...
    • Parameterization of turbulence models using 3DVAR data 

      Olbert, Agnieszka Indiana; Nash, Stephen; Hartnett, Michael (City University of New York, 2014-01-08)
      In this research the 3DVAR data assimilation scheme is implemented in the numerical model DIVAST in order to optimize the performance of the numerical model by selecting an appropriate turbulence scheme and tuning its ...
    • Remote sensing of surface waters in Ireland 

      Agarwal, Anuj; Taveneau, Adélaïde; Olbert, Agnieszka Indiana (Civil Engineering Research Association of Ireland (CERAI), 2018-08-29)
      An implementation of the WFD requires all surface waters in the EU to achieve at least good status; this requirement has not been achieved in Ireland. Just over 30% of transitional waters and 79% of coastal waters were ...
    • Turbulence modelling using 3DVAR data assimilation in laboratory conditions 

      Olbert, Agnieszka Indiana; Nash, Stephen; Hartnett, Michael (2013)
      The viability of turbulence parameter estimation in a numerical model using 3DVAR data assimilation technique is explored in this research. Water currents measured in a physical model are assimilated into the numerical ...
