Tsunami inundation modelling has been identified as one of the priority topics to be addressed in the five partner countries in the North-West Indian Ocean (NWIO) region in order to improve inundation mapping and evacuation planning in support of tsunami preparedness.

The TTF-31 Project will support finalisation of a Probabilistic Tsunami Hazard Assessment (PTHA model (V1.0)), including an exchange of experts to be trained in its architecture and use. There will also be a Scientific Exchange Meeting to share the PTHA results with the region for adoption, as well as report on the latest regional/international studies on the tsunami hazard in the Makran subduction zone. The project will also support the establishment of a NWIO Regional Working Group on Tsunami Inundation Modelling and Mapping (RWG-TIMM), with input from international experts, to foster ongoing regional cooperation and exchange of knowledge on inundation modelling and mapping. A gap analysis of tsunami inundation modelling and mapping capabilities in the region will be undertaken. The regional working group will aim to develop a unified methodology for tsunami inundation modeling in order to assure inter-comparable results throughout the region.

The project will provide information on existing approaches, methodologies and input data for tsunami inundation modelling and mapping. To facilitate joint learning and national implementation, the project suggests the establishment of national working groups on tsunami inundation modelling and mapping to facilitate and inform a gap analysis by the project in each of the five countries participating in the project (India, Iran and Pakistan with funding from the project; Oman and United Arab Emirates (UAE) through self-funding). The project will later use this information to provide recommendations to the NWIO countries about what fits best and how to proceed regarding the development of necessary and feasible approaches for tsunami inundation mapping.

The regional workshop it is intended to kick-off a joint working process among the five partner countries and the project team to identify the requirements for tsunami inundation modelling and mapping in the region. 

The Concept Note and Agenda are available here. 

The workshop has the following objectives:

• Providing background information on the TTF-31 project and related initiatives, such as the UN Ocean Decade Tsunami Programme and the UNESCO-IOC Tsunami Ready Recognition Programme (TRRP).
• Getting to know each other and develop regional partnership arrangements.
• Discuss the establishment of National Working Groups on Tsunami Inundation modeling and mapping (NWG-TIMMs), which are proposedas a mechanism to subsequently facilitate joint learning and national implementation of the project activities. National working groups should involve not only representatives from agencies, universities and research institutions, but also the local level, preferably from the community of the Pilot Areas to beinvolved in order to improve cooperation between science and application in the warning process. Representatives might therefore also be drawn from Provincial Disaster Management Organisations (PDMOs) and/or Local Disaster Management Organisations (LDMOs).
• Discussion and sharing of knowledge on principal concepts, methodologies and approaches for tsunami inundation modelling. Partner countries are invited to share their experiences and skills of tsunami inundation modeling and mapping.
• Presentation and discussion of the approach for a gap analysis in  each of the five countries and preliminaryresults.
• Outlook on further activities to be undertaken under the framework of the project, including next steps towards building a common understanding and joint strategy for tsunami inundation modelling in the region and nationally.
