3. ABSTRACTS
KEYNOTE: Use of MIKE 21/3 in the Hydraulic Analysis for the Dublin Port ABR Project
Adrian Bell (RPS), Tuesday 21 April 2015 at 10:30 - 11:00
This project essentially looked at the stability of a deepened approach channel and examined the impact of the dredging and
disposal for the scheme in support of a public planning hearing. The modelling used coupled MIKE 21 FM HD-SW-ST models as
well as well as MIKE 21 and MIKE 3 FM HD and MT models.
Environmental Impact Assessment of the SW Quadrant of Lekki Free Zone, Nigeria
Sandeep Bomminayuni (Waterco), Tuesday 21 April 2015 at 11:00 - 11:20
This talk presents an overview of the flood risk and water quality assessment studies carried out for the SW Quadrant of Lekki
Free Zone, a huge developmental area (30 sqkm.) located in Lagos, Nigeria. Hydrodynamic modelling of the proposed manmade
watercourses was performed to assess flood risk for the present day and climate change scenarios. Modelling of several water
quality parameters was performed using the MIKE 21 ECO Lab module to assess the impact of pollutants discharged through
urban runoff on the watercourses and environment. The model results show that the development would not be at risk of flooding
for the scenarios considered, however, the water quality in the manmade courses could potentially be inferior to the adjacent
Lekki Lagoon especially following rainfall events.
River Carron Wave Propagation and Engineering Assessment
Daniel Rodger (JBA Consulting), Tuesday 21 April 2015 at 11:40 - 12:00
The coastal town Stonehaven Aberdeenshire UK, is located between the River Carron and the North Sea. The area is exposed
to a number of complex coastal and fluvial risk processes and during extreme sea levels and specific wave conditions, waves
can enter the waterway channel and propagate upstream to create a unique flood risk. A numerical modelling study was
undertaken to quantify the effect of the channel waves, and to allow robust design of future flood defences on the lower stretches
of the River Carron. Following a joint probability analysis of offshore extreme waves and water levels to develop a range of return
period scenarios for the study, a spectral wave model was used to assess the wave transformation processes between the
offshore and nearshore region and then a Boussinesq wave model was used to investigate the behaviour of individual waves in
the river mouth and channel. The Boussinesq wave model was found to support local observations that the waves transform into
a soliton-like form, leading to higher water levels as they propagate upstream. Several engineering mitigation strategies were
considered using the model, including a nearshore breakwater, channel realignment and upstream wall raising.
Morphological Modelling of Braided Processes: Technology for Flooding and Erosion Management
Kazi Iqbal Hassan (Heriot Watt University), Tuesday 21 April 2015 at 12:00 - 12:20
This paper describes a two dimensional (2D) morphological model of one the world’s most dynamic rivers, the Brahmaputra. The
2D morphological model of the Brahmaputra was validated against ADCP measured velocities across the braided channels and
with historical annual sediment load. The 2D model predicted short-term to medium term bank erosion for planning of river
training works, assessed effectiveness and impact of the existing training works, and provided hydraulic and morphological
design variables for future training works.
A Regional Coastal Modelling System for the North West – from Wales to Scotland
Samantha Mullan (Intertek), Tuesday 21 April 2015 at 12:20 - 12:40
Intertek has developed a regional coastal modelling system for United Utilities. This modelling system covers UU’s entire area of
interest and stretches from the north Wales coast to the southeast coast of Scotland, including complex and dynamic
environments such as the Ribble Estuary, Morecambe Bay and the Solway Firth. To develop an efficient and practical system
that provides the client with an assessment and management tool that meets their requirements, with sufficient resolution in all
areas of interest over such a large and varied region, has been challenging. The presentation will provide an overview of the
modelling system, including the techniques employed, and some of the difficulties experienced.
Birds, Bats and Beyond – What’s that got to do with Water?
Nick Elderfield (DHI), Tuesday 21 April 2015 at 12:40 - 13:00
Innovation in modelling water environments is what DHI has been about for over 50 years. A detailed understanding of the
controlling physical conditions, coupled with a behavioural knowledge of critical species dependant on the water environment,
provides a scientifically robust approach to assessing historic and future change spatially and temporally. Our habitat modelling
approach has been successfully applied on a number of projects in the UK and the wider North Sea region, combining expertise
in water environments with the critical issues for today’s projects. Models always rely on data and, to this end, DHI have
developed sensing technologies from low cost, web-ready devices to integrated observation systems for birds and mammals.
KEYNOTE: Operational Real Time Control and Warning System for Urban Areas and Receiving Waters
Henrik Frier (Aarhusvand), Tuesday 21 April 2015 at 14:00 - 14:30
Experience gained during five years of design, development and implementation of a full scale real time urban water monitoring,
modelling and control and warning system is described, focussing on how to transit from desktop models and design plans to a
robust live operational system. The system uses volumes in the combined sewer system more efficiently by real time control of
valves, gates and pumps, thereby minimising the amount of untreated wastewater reaching the receiving waters during rain.
Further, a warning system forecasts deteriorated water quality in the receiving waters based on automatic operation of a series of
integrated numerical models of the urban drainage system and the receiving waters. The models use real time information from
the waste water treatment plants and the sewer systems and forecasted rainfall information from a Local Area Weather Radar.

4. ABSTRACTS
3D Thermal Dispersion Modelling in the Caspian Sea
Tom Ashby (WSP), Tuesday 21 April 2015 at 14:30 - 14:50
Assessing the dispersion of a thermal plume from a seawater cooling plant outfall in the Caspian Sea. Driving a MIKE 3 FM HD
model using a MIKE 21 SW model to generate current conditions. Complications and things to watch out for.
Using Agent Based Modelling to Understand the Impact of Human Behavioural Change in Flood Risk Management
Linda Geaves (Oxford University), Tuesday 21 April 2015 at 14:50 - 15:00
Linda has been looking at the long term costs for householders of different flood insurance scenarios in England using agent
based modelling. Agent based models provide a novel way of looking at the flood problem because they apply both human
behaviour and probabilistic physical outcomes to solve complex problems, while creating more socially reasonable model
outcomes. Linda’s model is backed up with data that she has collected from over 30 communities across the UK.
Investigating the Environmental Impact of Aquaculture on Marine Waters
Ted Schlicke (SEPA), Tuesday 21 April 2015 at 15:00 - 15:20
Ted will speak about SEPA’s use of MIKE 21 FM PT to quantify benthic deposition and connectivity between different fish farms
to establish the cumulative effect of medicines and fish waste.
Towards a British Isles Strategy for Tidal Range and Coastal Adaptation
Stuart Anderson (Conwy County Borough Council), Tuesday 21 April 2015 at 15:40 - 16:00
Stuart has a long history with tides on the North Wales coast, working with a number of high level, and high profile, projects
including MAREN2. He will present his thoughts and experiences on works carried out and proposed for combining coastal
protection with tidal range schemes.
Modelling of Extreme Conditions for Wave Overtopping at Weymouth Bay
Oliver Way (Hyder Consulting), Tuesday 21 April 2015 at 16:00 - 16:20
A wave model study of Weymouth Bay was undertaken for Weymouth and Portland Borough Council to investigate flooding in
the historical centre of Weymouth which is understood to be caused by tidal and fluvial waters overtopping flood defences,
groundwater rising above ground level in response to high tides and heavy rain and wave overtopping along the open coast /
Esplanade. The wave modelling results in this study are used to provide input conditions to the overtopping calculations which
will in turn be used as inputs to the models of overland flow to provide flood extents. MIKE 21 SW was applied to simulate
extreme wave conditions with combined extreme water levels. The model domain extends from Chesil Beach in the west to
Lulworth Cove in the east. Extreme water level data were supplied by the Environment Agency for Weymouth from the Coastal
flood boundary conditions for UK mainland and islands report (Environment Agency, 2012). Extreme wave values were also
obtained from this Environment Agency report at offshore locations on the model boundary. Extreme wave conditions were
considered for three directional sectors: south west, south and south east. A joint probability approach was applied for a range of
return periods and climate change epochs. Wave data were extracted at nearshore locations along the beach front of Weymouth
Bay. These data were used as input conditions for wave overtopping calculations (EurOtop) at site specific points along the
beach to determine overtopping discharge rates along the beach front.
Hydropower on the Zambezi
Alan Forster (AECOM), Tuesday 21 April 2015 at 16:20 - 16:40
Alan will talk about the modelling undertaken to support a feasibility study for a hydropower scheme on the Zambezi. The project
required a more detailed understanding of the flow regime within the river close to the intake structure. He will describe some of
the difficulties encountered whilst developing a 2-dimensional MIKE 21 FM HD model. Alan will identify the acknowledged
limitations of the model and explain that it has still proved to be advantageous to the decision process and therefore justified for
the project.
Slow response runoff modelling and 'real time' simulations - A Swedish perspective
Andy Wilson (DHI), Wednesday 22 April 2015 at 10:00 - 10:20
Andy Wilson (from DHI Sweden but a native of Scotland) will give an update to a presentation he delivered at the CIWEM Urban
Drainage Group in November 2014. Andy will talk about modelling of slow response runoff, in particular focusing on long term/
continuous simulation (rather than event based hydrology). Andy will illustrate his presentation with applications from both
Sweden and Scotland and will talk about the use the Rainfall Dependent Infiltration (RDI) model (a component of MIKE URBAN).
