APPROVED BY: Peter Barter This technical note has been prepared to document the coastal options development in support of the Phase 2 Options Assessment Report. It is intended to provide additional background on the stages within the options development leading to a finalised shortlist of options for delivering improved coastal resilience to the Western mainline. This technical note builds on the analysis presented by HR Wallingford in Appendix E of the Phase 1 Baseline Report . The focus of this document is primarily on the open coast – Sections 2, 3 and 4 – as an extended and more iterative process was carried out to determine the finalised options for shortlisting in these areas. E-1. Document Overview The structure of this technical note is as follows: Section E-2 assesses the hazard reduction achieved by each of the options considered; Section E-3 outlines the options which were modelled by HR Wallingford and summarises the results of this analysis; Section E-4 assesses the effectiveness of the options in the Exe Estuary (Section 1) taking into account the modelling results provided by HR Wallingford. Section E-5 assesses the effectiveness of the open coast options (Sections 2-4) taking into account the modelling results received from HR Wallingford, analysis of the maximum acceptable crest level and sensitivity analysis regarding the toe level of the new defence. Section E-6 summarises the short-listed options and their respective timings. E-2. Assessment of hazard reduction Assessment of hazard reduction of the options short-listed in Appendix A is presented in Tables E-1 to E-5 below. These tables show that the defences currently have a mixed level of performance and residual life, with longer residual life expected of those assets located in the estuaries. It can been seen that the majority of coastal options can reduce the hazard to a low level with appropriate design. However, beach management would not be sufficient to do this as a standalone option and would work better in combination with improvements to the structural defences.

E-3. Options modelling and results The modelling of the option performance was undertaken by HR Wallingford and further detail on the methodology, model calibration and results is provided in the Modelling Report (Appendix E, Phase 1 Baseline Report). This section presents the schematisation of the options modelled and the processing of the results. The results are then evaluated in section E-4 below. DeDeDescriptionDe scription of options Option 1 consisted of placing a revetment to +7 mOD throughout Sections 2 to 4. Where there is pedestrian access along the main defence (i.e. promenade) a 4.5 m crest width was included to reduce overtopping further. This option was tested under current conditions as well as under low, medium and high sea level rise scenarios in 2065 and 2115.

3 COASTAL OPTIONS DEVELOPMENT

Figure EEE-E---1111 Schematisation of Option 1 Option 2 consisted of a vertical seawall throughout to +10 mOD with a lower wall to +7 mOD fronted by a perched beach modelled at Dawlish station. The perched beach was held in place by a low-crested nearshore structure (at X m from the seawall) and would provide an increased amenity beach for the public. This would also replace the existing lower walkway beneath the platform, providing access along the top of the beach at high tide during calm conditions. The wall to +10 mOD was placed in front of the existing and therefore modelled in slightly deeper water.

Figure EEE-E---2222 Schematisation of Option 2 Option 3 considered at the effect of crest-raising along the existing defence line and modelled four crest levels: +7.5 mOD, +8 mOD, +8.5 mOD and +9 mOD. This was only analysed for the 2065 medium climate change scenario to give an indication of how a shorter term solution might perform.

Processing of oovertoppingvertopping results Overtopping results for a wide range of return periods from 1 in 1 (100% Annual Exceedance Probability (AEP)) to 1 in 1000 (0.1% AEP) were provided by HR Wallingford for each of the options modelled. Each of the options was analysed at 32 different locations along the frontage to take into account the variation in beach profile and the orientation of the shoreline/defence. To enable the effectiveness of the options to be evaluated, a number of processing stages were necessary; these are briefly described below: • Filtering of the results to focus on the key return periods of most relevance to the study (1 in 1, 1in 2, 1in 5, 1in 10, 1 in 20, 1 in 50, 1in 100 and 1 in 200) ; • Averaging of the filtered results to determine the mean overtopping rate for these return periods over adjacent locations to correspond with the coastal sub-sections considered in Appendix A; • Reviewing of the overtopping discharges for each return period against the thresholds for severe and extreme disruption events;

4 COASTAL OPTIONS DEVELOPMENT • Synthesis of the performance of the options under severe and extreme disruption events. E-4. Assessment of effectiveness The assessment of effectiveness looks at how efficiently the proposed options reduce wave overtopping along the open coast under future scenarios. This includes evaluating the performance of the options modelled by HR Wallingford and an assessment of how well the maximum acceptable crest level increase (relative to the rail head) performs. Additionally, a sensitivity analysis is carried out to determine the effects of changes in toe level to the defences’ performance. Evaluation of options modelling results The results of the HR Wallingford modelling are summarised in Tables E-6 and E-7 below. The former shows the standard of protection against extreme events (causing major disruption to the railway) and applies an overtopping discharge threshold of 100 l/s/m. The chosen option needs to provide resilience against infrequent extreme events and ideally such events would be limited to a frequency of less than once in 100 years (i.e. a 1 in 100 return period or greater). Another important consideration is the performance of the defences under a more frequent and less severe storm event, such as an event which might occur annually. An assessment of the standard of protection against low discharges (approximately 1 l/sm) is provided in Table E-7. From Table E-6 it can been seen that generally the rock revetment to +7 mOD performs well under extreme events in the medium term (2065) with a more varied standard provided in the 2115 high scenario. To achieve a similar level of protection during this period, an additional three metres of vertical wall would be required. It is important to highlight at this point that between these two scenarios there is an additional 0.7 m of sea level rise which contributes significantly to the reduction in standard of protection. When considering the standard of protection against moderate events, Table E-7 indicates the difficulty in limiting the frequency of these events. In many locations, the options modelled would struggle to limit the frequency of this type of disruption to an annual event.

6 COASTAL OPTIONS DEVELOPMENT

Analysis of maximum acceptable crest level In Workshop 6 (December 2015) it was agreed that a maximum increase in defence crest level above the railhead was acceptable. To reduce the impact on passenger views, this increase was defined as being 1.5 m above the railhead. It was therefore necessary to review the results presented in Section E-3.3 above with regards to this criterion. The track level and existing defence crest levels were collated and this maximum increase applied to all areas of the open coast frontage. The assumed maximum crest level is derived in Table E-8 and the performance results of these levels are tabulated in Table E-9.

These levels generally provide sufficient protection from overtopping in 2065 with some areas performing well in 2115 under the low or medium sea level rise scenarios. In most areas of the open coast, the standard drops significantly under the high sea level rise scenario in 2115, thereby indicating that further adaption may prove necessary if this scenario occurs.

Effect of toe level on option performance A sensitivity analysis was undertaken to evaluate the effect of defence toe level on the overtopping performance; the results are tabulated in Table E-10 below. As the toe level decreases, the required wall or revetment crest level increases to provide the same level of protection. This indicates the value of a beach management programme in both prolonging the life of a vertical wall and reducing the required crest level. This table also highlights how it is the more common “severe” events rather than the extreme storms which have the greatest influence over the required crest level.

8 COASTAL OPTIONS DEVELOPMENT E-5. Options assessment for Section 1 The options modelled for the Exe Estuary are two different wall heights of +4.6 mOD and +5.1 mOD (1 in 200 RP in 2065 and 2115, respectively). Full description of the methodology and results can be read in Appendix E of the Phase 1 Baseline Report. Due to the nature of the estuary and the model configuration, the options were only tested for the residual risk created by events exceeding these levels; the model runs are summarised in Table E-11 below. The results of the modelling are displayed in Figures E-3 to E-7 below. Table EE----11:11: Summary of model runs for Option 1 and Option 2 in the Exe Estuary

Option 2 2065 X

Option 2 2115 X X

Figure E-3 demonstrates how Option 1 reduces the flood level in the area surrounding the railway under a 1 in 10 return period event by approximately 1.5m. The predicted flood level is therefore below the height of the railway embankment and would cause limited disruption to services. A similar reduction in flood level is also achieved for the 2065 1 in 200 return period flood event. Some flooding is still predicted to occur landward of the railway embankment due to the large number of culverts connecting the two flood storage areas. Option 2 provides extended protection to the railway, but in the higher return periods in 2115 produces limited additional benefit when compared to Option 1. This is due to the model assumption that the Exeter Canal embankments are not raised as these are beyond NR’s ownership. The discussion surrounding whether to raise these embankments took place after the modelling runs had been completed so no further models runs to take account of this change were undertaken.

9 COASTAL OPTIONS DEVELOPMENT For the estuary walls, the protection provided by the options is higher as there is no outflanking from other embankments; water levels along the railway embankment at Starcross under a 1 in 200 return period event in 2065 are reduced by 1.5 m for Option 1. Option 2 reduces the water levels under a 1 in 200 return period event in 2115 by 1.6 m. In both these cases, although the water level in the estuary would be close to the top of the new defences causing temporary disruption under storm conditions, no long-term disruption would be expected to occur.

E-6. Finalised coastal short-list Taking into account the above analyses, the shortlisted options have been refined and combined to provide a holistic solution to managing the overtopping hazard. The solutions proposed embrace the preference for maintaining passenger views and allow for future adaptation in light of sea level rise estimates for 2115 and beyond being revised.
