Using MIKE FLOOD AD and ECO Lab to model polluted flood waters and riverine water quality

MIKE FLOOD now includes the option for a fully dynamic 1D-2D Advection Dispersion coupling, which increases the range of applications substantially.

The new AD coupling in MIKE FLOOD enables users to simulate new interesting aspects such as: -

• Floodplain contamination from polluted rivers.
• Impact assessment on river quality from pollutant sources in flood prone areas during flood events.
• The impact on concentrations of river pollutant in case of a release from an urban Combined Sewer Overflow.

MIKE FLOOD AD can be further enhanced by ECO Lab for advanced water quality simulations.

ECO Lab is the complete numerical laboratory for water quality and ecological modelling. You can develop exactly the model you need and describe the processes you wish. No ecological problem is too simple or too complicated for ECO Lab:

• Open Equation solver for coupled ordinary differential equations.
• Designed for point descriptions of processes of chemistry, ecology, etc.
• All equations, parameters contained in flexible, portable ECO Lab templates (use DHI supported templates or create your own).
• Integrated with DHI’s hydrodynamic models: Currently MIKE 11, MIKE 21 (hence MIKE FLOOD), MIKE 3 & MIKE SHE.

SuperGen UKCMER Course on Tidal Energy at Queen’s University Belfast

As part of their involvement in the SuperGen UK Centre for Marine Energy Research (UKCMER), formerly SuperGen Marine (www.supergen-marine.org.uk), Queen’s University Belfast held a Doctoral Training Programme course at the Queen’s Marine Laboratory in Portaferry during the week 27th to 31st May 2013. Participants from the various SuperGen partner universities attended the course which covered many aspects of tidal energy production from basic tidal mechanics through measurement of hydrodynamic parameters to performance of tidal energy devices and included a field trip to the SeaGen marine turbine installation in Strangford Narrows.

With support from The Academy by DHI, a full 1-day MIKE by DHI training course was included on 30th May providing instruction in the use of MIKE 21 FMHD to demonstrate the role of modelling in resource assessment and device location studies. This collaborative MIKE by DHI training course was presented by Dr Björn Elsäßer (QUB), with assistance from Steve Flood and Dr Suzie Clarke (DHI-UK).


The Bristol Channel area was used for the MIKE 21 FMHD training course. Participants created their own model mesh and then developed hydrodynamic models into which tidal turbines were added in order to investigate impacts on the overall flow field.


Many thanks to Dr Björn Elsäßer, Queen’s University Belfast, and all the participants.

An invitation to the 2013 MIKE by DHI UK User Group Meeting

Our Spring 2013 User Group Meeting is fast approaching, and we are looking forward to welcoming you to the event on the 19th of March 2013, and Seminar Day on 20th of March 2013, at the Lion Quays Waterside Resort, Nr. Oswestry, UK.

The event is now in its 15th year, and we are very pleased to announce that the event is once again free of charge to all existing and potential users of MIKE by DHI software, as well as those with a general interest in water modelling, engineering and management.

If you are new to MIKE by DHI software, this annual event attracts participants from across industry and academia. The format of the meeting allows exchange of experiences through user presentations plus formal and informal interaction with both UK and Head Office DHI staff.

On the first day, 19th March 2013, there will be a mixture of presentations of new and forthcoming software features and technologies, as well as practical case studies. The programme is nearly complete, and will feature the following presentations: -

Water Resources (incl. Urban)

• River Almond WQ Study (Atkins): A dynamic water quality model of the River Almond has been developed using MIKE 11 ECO Lab with an overarching aim of assessing the impact of Scottish Water assets on the water quality of the river. An extensive, recent (2011) water quality data set served as the basis for the model’s development, which also included inputs from sewer network modelling. The model has been used to identify water quality parameters and specific locations of concern in the River Almond system, providing Scottish Water with a detailed assessment of catchment needs. The work will continue with identification of strategic options to meet the requirements of the Water Framework Directive and the Urban Wastewater Treatment Directive.
• Hydrodynamic and Sediment Transport Modelling of Swindale Intake (MWH): Modification to the existing arrangements at the Swindale intake could negatively impact stilling pond hydrodynamics, which could impact fish passage and gravel management. A 2D hydrodynamic (HD) and sediment transport model (ST) to has been applied to assess the potential impact of the proposed works on sediment dynamics in the upstream channel and floodplain and in the proposed stilling pond.
• Flood Modelling with MIKE 21 (Arup): A look at two case studies of MIKE 21 flood modelling with some comments on the use of structures.

Marine

• Tidal Energy Resources Assessment for Tamar (Plymouth) Estuary Narrows (Hyder): Two MIKE21 FMHD models covering the English Channel and the Tamar estuary were developed to carry out an assessment of the tidal stream energy output potential. The Tamar model has been calibrated using continuous ADCP measured data at 3 locations. Three areas of high tidal stream power output potential with a mean tidal turbine output power density were identified in the Plymouth Narrows.
• A Multi-model Approach to Coastal Protection at Clacton (Mott MacDonald): Recent experiences with MIKE 21 FM ST and LITPACK while investigating the Clacton beachfront.
• Combined Thermal Plume from Multiple Power Stations using MIKE 3 (Atkins & TechnoEconomica): A detailed study of the issues involved in modelling multiple thermal and hypersaline discharges in to a warm environment. Issues of waste water recirculation, surface heat exchange and vertical stratification will be covered. Some suggestions on ways in which this process could be improved in MIKE 3 will be offered. Specifically this will concern ground heat retention and excessive night cooling in shallow waters, and also power station sub-models.

Porous Media (Groundwater)

• Ground Water Heat Flow (ESI): A presentation of some interesting thoughts and applications of FEFLOW.

On the second day, 20th March 2013, we will host a number of seminar style training and open discussion sessions. These sessions will focus on new and lesser know features of MIKE FLOOD, MIKE 21 and FEFLOW.

The use of 3D numerical modelling in groundwater research and water quality risk assessment

Matrix Solutions Inc. in Canada is using MIKE by DHI numerical modelling for ground-breaking research and valuable solutions for their clients. Two recent examples are: -

Feasibility study estimating lithium and potash rich brine deposit reserves
Matrix Solutions developed a 3D numerical modelling tool using among others FEFLOW to represent the complex groundwater flow system and evaluate various wellfield strategies. Using FEFLOW to develop their numerical model, Matrix Solutions was able to significantly reduce simulation time and reach a conclusion supporting a long time and low cost mining operation.

The importance of groundwater–surface water interaction in water resource assessments
In order to better understand and assess the groundwater –surface water interaction, Matrix Solutions applied our integrated modelling software MIKE SHE to two municipal water quality risk assessments in order to evaluate the sustainability of municipal water withdrawals.
