requirements

38. Severn Estuary Tidal Power Strategic EA
• Need: Inform a decision on whether the Government could support a
tidal power project in the Severn Estuary.
• Perform the environmental aspects of a feasibility of tidal power
generation in the Severn Estuary
• Challenge: Substantial package of specialist environmental impact
research, modelling and fieldwork for a range of tidal power options
• Complex modelling scenarios over a large area including
multidimensional hydrodynamic, geomorphological and ecological
impact models.
The Severn Bridge
• A substantial stakeholder and consortium engagement programme.
• Solution: Strategic Environmental Assessment (SEA) – 16
topic-based assessments
• Data Management and Governance – creation of central
project geodatabase and a seamless topographic surface
Information Management
from 4 digital data sources
• Multi-disciplinary Studies – tides, waves, sediment
movement, morphology, habitats, birds and water quality
• Tidal Yield Modelling – scheme optimisation
Combining LiDAR, Bathymetry and Local Surveys
• Benefit: A robust, integrated quantitative impact assessment, providing
objective, informed evidence of effects.
• Energy yield modelling, based on unique expertise provided a cost-
effective approach.

the outputs generated, ensuring value for money. 38

39. River Wandle Asset Inspection Survey
• Need: Fill gaps in knowledge of assets to better support asset
management planning strategy
• Undertake a condition survey of the River Wandle and produce a
report providing detailed information on every fluvial defence and
structure
• Challenge: Visit over 1,000 assets on either side of a dense, urban,
15km stretch of the Thames tributary
• Complete detailed survey of each asset in line with
Environment Agencies NFCDD dataset
Asset inspection via GPS
• Solution: Surveying was undertaken by a two person
enabled PDA engineering team experienced in asset condition inspections
• GPS enabled PDA used for digital field capture
• Drop down lists and auto-population to improve capture
• Custom tools creates to create sequenced map Auto generated map and

41. Flood Risk Management
Deben Flood Risk Management Strategy – Stage 1, River Deben, Suffolk
• Need: Prompted by growing concern over several areas
in Suffolk that are susceptible to flooding, the
Environment Agency commissioned the development of
a long-term strategy to manage the flood defences for
three of the Suffolk Estuaries
• Challenge: Complex tidal system with offshore undersea
banks impacting tidal prism
• Large, low lying and largely
uneconomic flood envelope
Martello defence tower
• Active local action group
• Solution: Utilised Black & Veatch’s Flood Damage
Economics Model (FDEM) as the basis of its economics
assessment.
• Team of surveyors captured existing defence line and
over 1,000 property thresholds. Each measurement was
interrogated against ‘off-the-shelf’ topographic data and
combined to created a the most detailed, seamless DTM
of the estuary to date.
• Benefits: 40 options were effectively assessed on 1,700 Consultation mapping
at risk properties and environmental receptors
• High-level cost-benefit assessment for all flood cells and
options to bring focus to the stage 2 detailed
assessments
• Enhanced understanding of estuary processes and the impact of managed retreat
• Workshops held with the Deben Estuary Partnership. including on screen 41
demonstrations of the risks and potential mitigations being considered
