Flood risk management is a critical aspect of disaster preparedness, especially in the face of climate change. As floods become more frequent and severe, decision-makers must evaluate strategies that maximise welfare while minimising economic losses. In this article, we delve into the importance and benefits of economic analysis for flood risk management. When developing flood defence schemes, evaluating the financial impact of flooding is crucial for several reasons: Cost-Benefit Analysis Assessing the economic consequences allows decision-makers to weigh the costs of implementing flood defence measures against the potential benefits. By comparing the costs of flood defences (such as construction, maintenance, and operation) with the expected reduction in damages, they can determine whether the investment is worthwhile. Resource Allocation Limited resources necessitate prioritisation. Evaluating economic impacts helps allocate funds effectively. If a flood defence scheme provides substantial economic benefits (e.g., reduced property damage and infrastructure protection), it becomes a priority for investment. Risk Reduction Understanding economic losses due to flooding enables planners to design flood defences that minimise damage. By identifying vulnerable areas and assessing potential losses, they can tailor defences to specific needs, reducing overall risk. Long-Term Planning Considering the economic impact over time is essential. Climate change and urban development affect flood risks. Evaluating economic consequences helps create adaptive and resilient flood defence strategies for the future. It is also important to mention other damages beyond the risk to property or businesses that flooding can cause such as risk to life, mental health and the costs of evacuation and emergency services. Flooding can have long-lasting repercussions for people, the immediate financial impact can lead to long-term vulnerability if they are not able to quickly recover and the emotional consequences can also result in lasting negative psychological effects, creating a need for mental support. Economic analysis shouldn’t be just about the immediate financial loss, it should also consider the long-term more insidious impacts of flooding to ensure informed decision-making, efficient resource allocation, and effective flood defence strategies. The Damage Calculator tool within Flood Modeller enables users to quickly evaluate the economic cost of flooding, including damage to buildings, risk to life, business disruption, damage to vehicles, mental health, emergency services costs, health costs and evacuation costs. The mapping and reporting features in Flood Modeller allow you to analyse and present large volumes of complex economic data in easy-to-understand ways.

With the upcoming release of Flood Modeller 7.1, the hydrologists’ world is going to be turned upside down - Forget the spreadsheets, hydrological workflows and analysis will soon be fully integrated within one software! Coming in early May, the next phase in the implementation of our unique hydrological module, Hydrology+, will offer outstanding integrations and time savings to revolutionise how practitioners work day-to-day. The first phase of the implementation included direct access to FEH webservice to download and import catchment descriptors, seamless access to hydrological data sources such as the National River Flow Archive and the Environment Agency's national river gauge data, as well as the ability to explore and utilise observed data directly from within the Flood Modeller interface. These exclusive features, alongside the introduction of the WINFAP and ReFH2 cloud licensing, provided a step change for the flood hydrology discipline by providing direct access to necessary data, eliminating data request delays, speeding up workflows and allowing users to quickly set up simulations and calibrate models. Coming in early May Flood Modeller 7.1 takes the integration further by introducing new features to streamline and simplify hydrology workflows and analysis and fully integrating WINFAP and ReFH2.4 into Flood Modeller. Calculation points Quickly and easily define flood estimation points across the UK by bringing together FEH catchment descriptors and gauge data to enable detailed FEH analysis using WINFAP and ReFH2.4. FEH Analysis The full integration of workflows with WINFAP and ReFH2.4 allows flood analysis to be quickly and consistently completed, with all results securely stored in the Hydrology+ database. Users can also inspect and visualise results directly at each calculation point. Hydrology projects Group your analysis together using the new Hydrology+ project, allowing sharing and exporting at the click of a button.  Projects allow the storing of detailed hydrological analysis with models, ensuring data provenance and more effective model re-use. Hydrology+ database Our secure, structured database for holding your hydrology data and analysis. The new backup function means you can save your work in your local database as well as share it with colleagues and clients. Scaling tool Reconcile your ReFH2 and WINFAP analyses and combine with scaling factors to create inflow hydrographs for 1D or 2D model boundaries and add the data to the Hydrograph library.  Hydrology+ guides users to apply up-to-date climate change allowances from the Environment Agency, SEPA, Natural Resources Wales and the Department for Infrastructure. Hydrograph library Your completed FEH analysis will form a library of flood hydrology, covering different return periods, storm durations and climate change futures, which can be used directly within your 1D and 2D models. Design Rainfall As well as river flows, Hydrology+ allows the calculation of design rainfall using the last rainfall model (FEH22) and ReFH2.4.  Rainfall can be added directly to Flood Modeller 2D models or exported for use in other analyses. No more spreadsheets, manual data requests, or labour-intensive handling of data from one software package to another, practitioners can work more quickly and efficiently thanks to streamlined workflows and access to multiple data sources directly in Flood Modeller. Reviewers can annotate projects directly in the software and the data can be seamlessly passed on to the hydraulic modellers for perfectly smooth collaboration. The upcoming release will also include: New Damage Calculator Your economic analysis can be enhanced as the tool will soon enable you to calculate multiple additional damages. We can’t wait to release the next version of Flood Modeller and open the next chapter of hydrological and hydraulic analysis – Watch this space!

Earlier this year, we announced that Flood Modeller’s cloud-based licensing would be our default deployment option for all licences moving forward due to the wide range of additional benefits it brings, including greater resilience across an organisation's IT infrastructure. As expected, Flood Modeller’s cloud-based licensing provides all the functionality our existing network licensing offers, including: Multi-user access to the software, across any machine Access to additional features, such as Hydrology+ Enhanced deployment options, including virtual machines However, it also provides many other benefits, including: Managed licence updates Server migration and maintenance options Greater resilience across your IT infrastructure In this article, we highlight the additional benefits our cloud-based licensing brings, over our traditional network licensing, in a little more detail. Managed licence updates Our cloud-based licensing allows us to deploy all of your licence updates on your behalf, removing the administrative burden and need for internal IT support. Whether it’s an annual update following your support and maintenance renewal, temporary upgrade to one of your licences or the inclusion of new products such as WINFAP or ReFH2, we can apply all of these updates remotely and usually within just a couple of hours, reducing any potential downtime in the use of the software. Server migration and maintenance options Another benefit of our cloud-based licensing is the ability to independently migrate your Flood Modeller licence from one server to another during a scheduled maintenance period. You no longer need to request support from Jacobs, create new containers or align calendars to ensure you experience no downtime. Should the server or Microsoft apply an unwanted update, taking your software offline, it’s also extremely quick and easy to troubleshoot the issues and undertake maintenance to resolve the problem, including reinstallation of the licence to get your software up and running. Greater resilience Finally, and most significantly, our cloud-based licensing provides greater resilience across your organisation as you are able to deploy your Flood Modeller licences across two separate servers, without having to split your licence portfolio in half. This means if one of your servers was to go offline or was scheduled to be updated, you would still be able to access 100% of your licences without any impact at all. For smaller organisations, the benefit is that you can bypass the company server altogether and connect two separate machines directly to our Licensing Cloud, removing any potential company server failures. What next? If you’re currently using a standalone licence, you can upgrade to a cloud-based licence and access all of the benefits detailed above for a one-off licence fee. If you’re currently using our legacy network licensing, you can migrate to our cloud-based licensing at no additional cost. Please contact Alastair Sheppard on 0203 980 2407 to discuss either option in more detail.
