  • Management of seawater intrusion in unconfined coastal aquifers 

    Javadi, Akbar; Hussain, Mohammed S.; Abd-Elhamid, Hany Farhat; Sherif, M. M. (European Group for Intelligent Computing in Engineering (eg-ice), 2013-07)
    This work presents a new methodology to control seawater intrusion in coastal aquifers using artificial surface recharge. The proposed method is based on a combination of abstraction of saline water near shoreline and ...
  • Numerical modelling of the impacts of sea level rise on seawater intrusion in unconfined coastal aquifers 

    Hussain, Mohammed S.; Javadi, Akbar; Robin, V. (University of Exeter, UK, 2014)
    This study presents the application of a density-dependent finite element model to simulate the transient effects of sea level rise (SLR) on seawater intrusion (SWI) in a conceptual case of unconfined aquifer. The model ...
  • Optimal control of seawater intrusion in coastal aquifers 

    Javadi, Akbar; Hussain, Mohammed S.; Sherif, M. M. (Durham University and the UK Association of Computational Mechanics in Engineering (ACME), 2013)
    Seawater intrusion is one of the most serious environmental problems in many coastal regions all over the world. This is because mixing a small quantity of seawater with groundwater makes it unsuitable for use and can ...
  • Cost-Effective Management of Sea Water Intrusion in Shallow Unconfined Aquifers 

    Hussain, Mohammed S.; Javadi, Akbar (SWIM23, 2014-06)
    The cost efficiency aspects of different hydraulic barriers to control seawater intrusion (SWI) in shallow unconfined aquifer are investigated using the direct integration of simulation model with multi objective optimization ...
  • Enhancing resilience in urban water systems for future cities 

    Mugume, Seith; Diao, K.; Astaraie-Imani, Maryam; Fu, Guangtao; Farmani, Raziyeh; Butler, David (IWA Publishing, 2015-07-07)
    In future cities, urban water systems (UWSs) should be designed not only for safe provision of services but should also be resilient to emerging or unexpected threats that lead to catastrophic system failure impacts and ...
  • Reflections of a Water Professional: Essays in the Philosophy of Engineering 

    Ward, Sarah (University of Exeter, 2015-05-07)
    Philosophy of Engineering is a reasonably new field of thought when compared to philosophy of science or technology (Pauli, 2012; Vermaas et al., 2014). Taking this further, philosophy of water management is an even newer, ...
  • Improvements in vortex flow control design to increase sewer network flood resistance 

    Newton, Christopher J.; Jarman, D.S.; Memon, Fayyaz; Andoh, Robert; Butler, David (International Water Association (IWA), 2013)
    Flow controls are used within the water industry to manage the flow through sewer networks by attenuating flows at convenient or critical locations. Many sewer networks, regardless whether the systems ...
  • Cost-efficient control of wastewater treatment plants to reduce greenhouse gas emissions 

    Sweetapple, Christine; Fu, Guangtao; Butler, David (IWA Publishing, 2014)
    This research investigates the potential of improved wastewater treatment plant control for the cost-efficient reduction of greenhouse gas (GHG) emissions, providing a detailed exploration of the decision variable search ...
  • Identifying sensitive sources and key control handles for the reduction of greenhouse gas emissions from wastewater treatment 

    Sweetapple, Christine; Fu, Guangtao; Butler, David (Elsevier, 2014)
    This research investigates the effects of adjusting control handle values on greenhouse gas emissions from wastewater treatment, and reveals critical control handles and sensitive emission sources for control through the ...
  • A methodology for probabilistic real-time forecasting – an urban case study 

    Rene, Jeanne-Rose; Madsen, Henrik; Mark, Ole (IWA Publishing, 2013)
    The phenomenon of urban flooding due to rainfall exceeding the design capacity of drainage systems is a global problem and can have significant economic and social consequences. The complex nature of quantitative precipitation ...
  • A preliminary sustainability assessment of innovative rainwater harvesting for residential properties in the UK 

    Melville-Shreeve, Peter; Ward, Sarah; Butler, David (Southeast University, 2014)
    Rainwater harvesting (RWH) has yet to see significant uptake in UK households, primarily due to a lack of innovation in residential RWH system types. This paper presents the results of preliminary investigations into a ...
  • Hydrological Applications of Artificial Neural Networks 

    Duncan, Andrew (University of Exeter, 2010-09-10)
    This paper looks at two example applications of Artificial Neural Networks (ANNs) to hydrology. The first implements a Multi-Layer Perceptron (MLP) to correct flow-rate simulations from the WRIP simulator ...
  • Early Warning System for Bathing Water Quality 

    Duncan, Andrew; Keedwell, Edward; Djordjevic, Slobodan; Savic, Dragan (Defra, UK, 2013)
    Poster describing use of Artificial Neural Networks (ANN) in a Receiver-Operating Characteristic (ROC) scenario to predict bathing water quality exceedances at beaches in the SW UK.
  • Comparison of machine learning classifier models for bathing water quality exceedances in UK 

    Duncan, Andrew; Tyrrell, Deborah; Smart, Nicholas; Keedwell, Edward; Djordjevic, Slobodan; Savic, Dragan (IAHR (International Association for Hydro-Environment Engineering and Research), 2013)
    The revised Bathing Water Directive (rBWD) (2006/7/EC) of the European Parliament requires monitoring of bathing water quality and, if early-warnings are provided to the public, it is permissible to discount a percentage ...
  • Machine Learning-Based Early Warning System for Urban Flood Management 

    Duncan, Andrew; Keedwell, Edward; Djordjevic, Slobodan; Savic, Dragan (University of Exeter, 2013)
    With the growth in urban population and other pressures, such as climate change, the impact and severity of urban flood events are likely to continue to increase. “Intelligent water networks” are viewed as the way forward ...
  • CADDIES: A New Framework for Rapid Development of Parallel Cellular Automata Algorithms for Flood Simulation 

    Guidolin, Michele; Duncan, Andrew; Ghimire, Bidur; Gibson, Mike; Keedwell, Edward; Chen, Albert S.; Djordjevic, Slobodan; Savic, Dragan (IWA (International Water Association), 2012-07-20)
    A recent trend in the development of flood simulation algorithms shows the move toward fast simplified models instead of slow full hydrodynamic models. CADDIES is a research project that aims to develop a real/near-real ...
