Tidal energy is one of the most predictable forms renewable energy. Although there has been much commercial and R&D progress in tidal stream energy, range a more mature technology, with power plants having history that extends back over 50 years. With 2017 publication "Hendry Review" examined feasibility lagoon UK, it timely to review plants. Here, we explain main principles plants, two research areas: present future resource, optimization We also discuss how variability electricity...
The COVID-19 pandemic has significantly impacted various aspects of life, including environmental conditions. Surface water quality (WQ) is one area affected by lockdowns imposed to control the virus's spread. Numerous recent studies have revealed considerable impact on surface WQ. In response, this research aimed assess in Ireland using an advanced WQ model. To achieve goal, six years monitoring data from 2017 2022 were collected for nine indicators Cork Harbour, Ireland, before, during,...
Europe's ageing wastewater system often combines domestic sewage with surface runoff and industrial wastewaters. To reduce the associated risk of overloading treatment works during storms, to prevent backing-up into properties, Combined Sewer Overflows (CSOs) are designed networks release excess discharge rivers or coastal waters without treatment. In view growing regulatory scrutiny increasing public concern about their excessive frequencies potential impacts on environments people, there...
This paper presents a new freeware simulation tool (IberWQ) for 2D water quality modelling in rivers and non-stratified estuaries. The model computes the spatial temporal evolution of several species variables which are relevant evaluation environmental status estuaries, including: Escherichia coli, dissolved oxygen, carbonaceous biochemical oxygen demand, organic nitrogen, ammoniacal nitrate–nitrite temperature salinity. A depth-averaged transport equation is solved each variable with mass...
This study considers environmental impacts and the power production potential of a number coastally attached tidal lagoons, proposed along North Wales coast, UK. Initially, impoundment shape, turbine sluice gate locations were modified according to regional bathymetric data. A refined 0-Dimensional approach was implemented optimise lagoon operation, based on given specifications. In turn, two-dimensional numerical model, an unstructured triangular mesh, has been simulate hydrodynamic...
Abstract The increasing rate of anthropic activities in flood-prone areas and the effects climate change are aggravating dangers posed by floods to people. One main reasons for fatality during flood events is walking through floodwaters. Although authorities strongly advise against waters, evacuations or accessing flooded emergency services might be necessary. This research proposes a novel approach resilience retrofitting existing infrastructures enhance evacuation access routes reducing...
Abstract Extreme flood events are becoming more frequent and challenging due to climate change. Key objectives of this study evaluate different criteria used in assessing the hazard people during and, once determined, most suitable method is then assess safest route(s) for evacuation a event particular case study. The results application two analysed terms assessment with being based on widely empirical approach mechanics approach. Both an extreme flash flood, which occurred 16th August 2004...
This paper presents details of a numerical modelling study the Cardiff–Weston barrage proposal for Britain’s River Severn, previously studied by Severn Tidal Power Group. The focuses mainly on investigating potential far-field and near-field hydro-environmental impacts using an integrated one- two-dimensional model. model was set up large domain, starting from outer Bristol Channel close to Lundy Island tidal limit near Gloucester. Potential changes in water elevations, currents consequently...
In this study, enhancements to the numerical representation of sluice gates and turbines were made hydro-environmental model Environmental Fluid Dynamics Code (EFDC), applied Severn Tidal Power Group Cardiff–Weston Barrage. The extended domain EFDC Continental Shelf Model (CSM) allows far-field hydrodynamic impact assessment Barrage, pre- post-enhancement, demonstrate importance accurate hydraulic structure representation. found significantly affect peak water levels in Bristol Channel,...
Pathogens in nearshore coastal waters have far-reaching public health and economic implications. Faecal indicator organisms (FIOs) are commonly monitored modelled to indicate pathogen levels waterbodies. FIO decay modelling is an integral part of numerical hydro-epidemiological models simulate the die-off FIOs water bodies. This paper identifies limitations one comprehensive widely used models, developed by Stapleton et al. enhances model remedying limitations. The identified are: (i) rates...
Eutrophication, usually caused by excessive nutrients from human activities, may cause dire environmental consequences such as harmful algal blooms and fish kills. Turnover in eutrophic stratified lakes is dangerous for aquatic life. Solutions reducing stormwater run-off lake restoration are costly take years to develop. Therefore, real-time modelling intervention of turnovers important improving water quality Mechanistic models that solve the equations governing processes require...
Gates and weirs are frequently used hydraulic structures employed for controlling water flow rates in irrigation drainage networks. Therefore, accurately estimating the discharge coefficient (Cd) is important precise measurement. The present study intelligent predictive models modeling Cd labyrinth sluice gates. For this purpose, key dimensionless parameters reliable experimental datasets were used. support vector regression (SVR) model was hybridized with particle swarm optimization (PSO)...
The renewable energy route map for Wales outlines ambitious targets 50% renewables by 2025. Welsh coast, subject to tidal ranges of the order 13 m and flows in excess 3 m/s, is thus an ideal position significantly contribute these targets. Tidal stream emerging sector a relatively small number devices are at various stages development Wales. However, before such demonstration or arrays can be applied larger scale, consents permissions must obtained ensure safe environmentally responsible...
