SI Ocean Project: Tidal & Wave Energy



Share your data with internal and external clients with the help of MIKE CUSTOMISED! The above example demonstrates on-line access to DHI wave and tidal flow model simulations for energy resource scoping studies - view the interactive map at http://si-ocean.dhigroup.com/map

In 2011, 3.4 MW of wave and tidal energy devices in advanced stages of technology development had been tested across Europe. The International Energy Agency Ocean Energy Systems (OES-IA) vision document, "An International Vision for Ocean Energy”, has forecasted a global wave and tidal deployment potential of 337GW by 2050. Reaching these deployment targets would see long-term benefits including a reduction in carbon emissions, greater security of supply, and economic benefits through job creation and inward investment. If Europe is to maintain a global lead in ocean energy and gain the benefits associated with meeting these targets, an aggressive deployment trajectory will be required. Read more >>>

SCOUR AROUND MARINE STRUCTURES: Dealing with scour related problems in water environments
Date: Thursday 23 Oct - Friday 24 Oct 2014
Location: DHI, Agern Allé 5, DK-2970 Hørsholm, Denmark
Language: English

This two-day, thematic course introduces you to the procedures of analysis related to assessing scour risk at marine structures. The focus is on offshore wind turbine foundations and how to protect against or mitigate the scour formation by applying scour protection systems of, for instance, rock dump or mattresses. After the course the participant will be able to identify and define scour issues, asses the risk of scour and possible mitigation solutions for various types of marine structures and obtain the recent knowledge gained over the last decade from significant development and research within the field of marine scour.

Scour is a well-known issue for hydraulic and marine engineering. Scour occurs when structures are placed on erodible beds and exposed to current and waves. The foundations of e.g. offshore wind turbines are often erected in harsh hydrodynamic environments, exposed to tidal currents and large waves individually or in combination. Therefore, it is essential to have a detailed understanding of how these hydrodynamic environments affects the structure as a whole, including the foundation and the interaction between flow, structure and sea bed to ensure short– and long term stability. Evidently, the formation of scour around marine structures can pose a threat to the structural stability and the cables transporting electricity. Read more...

MIKE 21 OS FM: Oil spill modelling using flexible mesh
Date: Monday 08 September - Tuesday 09 September 2014
Location: Southampton, United Kingdom
Language: English

This two-day course teaches you the fundamentals of 2D oil spill modelling using flexible mesh, how to setup and model the fate and transport of oil using the MIKE 21 Oil Spill model (OS) FM.

Oil spills pose serious threats to water environments and place massive pressure on the entities that are responsible for the emergency response and clean-up operations, such as oil companies and national authorities.

The Oil Spill module simulates the spreading and weathering of suspended substances using a dedicated oil spill template. Oil spill modelling is important for emergency response planning and environmental impact assessment. Oil spill models predict the spreading and weathering processes acting on the spilled oil. Results can be evaluated with respect to the impacts on flora, fauna and selected species or habitats. Read more...

Abstract

This paper presents a new marine water quality forecasting system for real-time and short-term predictions. The forecasting system comprises an integrated catchment-coastal model and a database management system. The integrated model is validated in an Irish catchment-coastal system using hydrodynamic and water quality data. The forecasting system was then used to provide short-term and real-time forecasts of Escherichia Coli (E. coli) and Intestinal Enterococci concentrations (IE) in the near-shore coastal waters of Bray, Ireland. Two hind-cast scenarios were simulated: 5F in which predictions were based on rainfall forecasts only; and I-5F where forecasts of 5F were improved by incorporating real-time data. Results indicate that predictions of E. coli of scenario I-5F are improved. Also predicted IE concentrations by Scenario 5F were comparably higher than the I-5F predications, but due to the wide scatter of observed IE concentrations, the superiority of one scenario over the second could not be definitively determined.

Keywords: Real-time forecasts; integrated model; marine water quality; three-dimensional hydrodynamics; MIKE; catchment modelling

Latest presentations confirmed for the MIKE by DHI Symposium on 13th May 2014

Clifford Williams (Modelling and Forecasting, Environment Agency) has kindly agreed to give a talk on 'Real Time Flood Forecasting in the Environment Agency'. In the context of the recent winter floods and storm surges, the presentation will focus upon flood forecasting systems used by the Environment Agency, how the Environment Agency interfaces with the Met Office, the hydraulic models used by the Environment Agency (incl. MIKE 11) and how the service is delivered (e.g. to Flood Resilience Teams).

Since 2002 DHI has operated an early warning system for
bathing water quality. It all began in Copenhagen when
the harbour bath was a reality, but since then the forecast
system has spread to a number of Danish and Swedish
municipalities and most recently a New Zealand municipality
has also initiated a similar system. The advantages of the
bathing water system are manifold: 1) It complies with the
EU bathing water directive, 2) it protects the public from
getting exposed to sewage water and 3) it allows the
municipalities to proactively monitor and manage the
bathing waters.
Adam Leonard-Williams (Senior Metocean Scientist, Met Office) will also be giving a presentation on 'Just how severe was the 2013/14 winter and how did the Met Office wave model perform?'. These topical presentations will be followed up within the training sessions on the second day of the conference by seminar style briefings on our own innovative forecasting technologies: -

  • Introduction to MIKE CUSTOMISED Real Time – monitoring, flood forecasting, early warning and efficient operational controls for urban and riverine environments – comprising a live demonstration of the technology, selected relevant case studies and Q&A session.
  • Introduction to a MIKE CUSTOMISED Bathing Water Forecasting System, for example http://ostjylland.badevand.dk/ (in Danish but self-explanatory!). The presentation will introduce the bathing water forecast system and the data / models needed to build a similar system. It will be followed by Q&A session.

The world's water consumption rate is doubling every 20 years — twice as fast as the population growth rate. By 2025, water demand will exceed supply by 56%.

The critical need for water to sustain all aspects of human activity has driven us to inhabit floodplains and deltas close to rivers. Today, 82% of the global population lives in these areas and is exposed to a high risk of flooding.

We constantly strive to develop a robust understanding of the physical water environment as a precursor to any analyses influencing decision-making. Applying state-of-the-art modelling technologies and analytics ensures that we achieve this. We work closely with our clients and stakeholders to appreciate the water management issues that may affect their project outcomes. In so doing, we develop solutions that are appropriate, cost-effective and environmentally responsible.

Conducting a flooding study for Jaslovske Bohunice Nuclear Power Plant in Slovakia

We helped Jaslovske Bohunice Nuclear Power Plant ensure it has adequate flood prevention measures in place in the event of extreme rainfall.

The tsunami that severely damaged Japan’s Fukushima Nuclear Power Plant on 11 March 2011 highlighted the global concern for ensuring the safety of nuclear power plants. After the tsunami, crisis managers in the nuclear energy sector started to prepare and upgrade risk studies, taking all possible sources of risk into account. Read more >>>


Pushing the Boundaries – New Issues and Applications in Groundwater Modelling
Date: 13 May 2014
Event type: Conference
Organised by: Groundwater Modeller’s Forum, Hydrogeological Group
Venue: Birmingham

The UK Groundwater Modellers’ Forum is holding its 12th workshop on new issues and applications in groundwater modelling in the UK. Read more >>>

DHI will be presenting at the above Groundwater Modellers' Forum event on the 13th May 2014. Roberta-Serena Blasone (DHI) will give a talk on 'Coupling groundwater and ecological models (MIKE SHE & ECO Lab)' at the conference, focussing upon: -
  • Two of the key objectives of the European Water Framework Directive (WFD) are: 1) to protect and enhance the status of aquatic ecosystems (and terrestrial ecosystems and wetlands directly dependent on aquatic ecosystems) and 2) to provide for sufficient supply of good quality surface water and groundwater as needed for sustainable, balanced and equitable water use. These requirements, together with the growing acceptance of the integrated water resource management approaches that treat catchment management holistically, provide a strong motivation to develop integrated hydrological and water quality tools that can address problems related to ecological status and restoration. In particular, managers need to be able to quantify changes in ecosystem status caused by changes in catchment management. A new and powerful eco-hydrological modelling tool has been developed, combining a generic ecological modelling tool (ECO Lab) with a fully integrated catchment modelling tool representing surface water, soil- and groundwater as well as water quality processes (MIKE SHE). This paper will present applications of this new tool to case studies involving wetland ecosystems in Denmark and the US.
If you are attending the above event, you are most welcome to participate in the free 'Groundwater Modelling with FEFLOW' training course on the following day (14th May) at our User Group Meeting venue (easily accessible from Birmingham). Read more >>>

Discharge calculator for MIKE Zero 2014 64-bit

A simple extension to the standard MIKE 21 Discharge Calculation tool that adds support for multiple cross sections. The points defining the cross sections must be given as j,k (grid) coordinates, and written in a text file as follows: -
Example

! j1,k1 j2,k2 Name
50,50 55,55 firstCRS
50,75 55,80 secondCRS
55,80 60,85 thirdCRS
60,85 65,90 forthCRS
65,90 70,95 fifthCRS
For installation, you need to have MIKE Zero 2014 64-bit on your PC. It does not need to be located in any specific place, simply copy and unzip to any folder. We have also attached a template text file with j,k coordinates.


Notes: -
  1. Care should be taken when using the tool with MIKE 11 Maps output (h,p,q) to calculate combined discharges for rivers and floodplains. If a 1D river channel is very nearly sub-grid (i.e. the MIKE 11 channel occupies only one MIKE 21 cell), the 2D resolution across the river may not be sufficiently fine to accurately calculate the topographic properties (e.g. local water depth), and hence the discharge component, of the river channel. In such cases you should run the tool on the MIKE 21 results (e.g. floodplain flows only) and add the calculated discharges to 1D discharges exported from MIKE 11 (e.g. from within MIKE View).
  2. Generally, there is a high degree of uncertainty in providing combined discharges at river nodes; for example, the orientation of the cross section will vary the calculated discharge (flows will be different if the ‘cross sections’ are normal to either the river channel or valley itself), similarly integrating discrete points within the main river bed in 2D may deviate from the 1D discharge results at the same location, some floodplain configurations are not conducive to calculating a single combined flow rate, etc. As such, we would require that you undertake to verify the derived outputs to satisfy your own quality assurance procedures (as you would with any numerical modelling exercise).
  3. Please be aware that this tool is non-commercial and is provided ‘as is’ without warranty. The tool has not been subjected to the same rigorous validation and improvement / update programme as our commercial software and, as such, is to be used at your own risk. The functionality and accuracy of the tool must be checked and verified prior to use.

ICE Flooding 2014
Sustainable Flood Risk Management for Communities and Infrastructure
13 May 2014 - London, UK

DHI will be at the ICE Flooding Conference 2014 in London on the 13th May 2014 and are very happy to extend an invitation to clients and partners (who are inexplicably unable to join us at our User Group Meeting that same day!), to discuss the newest developments in the market, and to share visions and ideas on future opportunities.

Dr Michael Butts (Head of Innovation, DHI) will give a talk on 'Integrating flood risk into catchment management' at the conference, touching upon: -
  • Flood risk must be managed and planned both locally and at the catchment scale
  • Illustrative cases where we have had to address fluvial, urban, groundwater and coastal flooding and their interplay
  • Resolving the conflict between protecting infrastructure and the built environment and restoring riparian ecosystems
  • To adapt effectively we need to move from flood forecasting to real-time catchment management
If you are attending ICE Flooding 2014, you are most welcome to attend one of several flood risk related training seminars on the following day (14th May) at our User Group Meeting venue (easily accessible from London). Read more >>>

Assessing The Impacts Of Rural Land Management Change On Flooding And Flood Risk (The Catchment Approach)

Following on from this post, a few more links focussing on the work of Jong-Sook Park for the Parrett catchment in SW England and its Tone subcatchment: -
Here a fully integrated MIKE SHE/MIKE 11 model was applied to the entire Parrett catchment to model the complex hydrological response of the catchment; 2D overland flows, groundwater components (both unsaturated zone and saturated groundwater zones), 1D river flows and their interactions.

Representation of vegetation growth in channels and floodplains

MIKE 11 has long been able to manipulate channel roughness (Manning's n) with a time series file. This can be very useful in modelling the effect of long term vegetation growth in unmaintained river channels, and to optimise river maintenance regimes. In fact, there are a number of ways to vary roughness during a MIKE 11 simulation: -

1) Resistance factor varies by time

Set as a boundary condition.
  • Boundary description: Global or Distributed Source
  • Boundary Type: Resistance factor
The time series file contains a multiplication factor which is applied to the defined channel roughness during the simulation (e.g. at each time step).

2) Resistance factor varies by a function of depth, velocity, both, etc

Set as a hydrodynamic parameter.
  • Bed Resist. Toolbox
  • Bed resistance equation: Not active, function of ln(velocity*Hydraulic Radius), function of depth, function of velocity or Table (Velocity, Resistance value)
All features (equations and table) can be defined both globally and locally, and for uniform or triple zone approaches.

Additionally, time varying roughness is also possible in MIKE 21 (e.g. for 2D flow on floodplains when using MIKE FLOOD). Please see the example below: -
