Appraisals & Economic Analysis
Project appraisal involves a detailed evaluation process to assess a proposed project's feasibility, viability, and potential. It often includes comparing various options using economic analysis and considering technical, social, management, and environmental factors.
Flood Modeller enables quick evaluation and economic assessments by streamlining model building using automation tools. You can then compare the cost and benefits of each option using its wide range of features.
Key benefits
⟶ Automation tools enable you to streamline model build, and quickly set up multiple model runs
⟶ Advanced solvers enable you to run large, detailed models in minutes instead of days
⟶ Quickly appraise the benefits and costs of each option, reducing the time and effort it takes to process model results.
⟶ Perform event damage, average annual damages, present value damages
⟶ Increase your productivity using the GIS tools and inbuilt workflows to quickly undertake economic analysis
⟶ Take into account climate change, failure of existing structures, construction of new structures or other factors
⟶ Use the mapping, graphing and reporting capabilities to quickly visualise and communicate your economic analysis
Webinar
Damage calculations using Flood Modeller
In this webinar, Stephen Bilby, Senior Flood Risk Analyst at Jacobs, will provide an overview of Damage Calculator input datasets, operation and outputs, allowing you to better understand the economic damage caused by a flood event.
Streamline your processes
Flood Modeller’s GIS interface and model building tools automate much of the model build process. The simulation builder helps you to quickly set up a series of runs using different model configurations/scenarios and events data.
The Batch Runner enables you to automate the running of multiple simulations and the GIS tools streamline the process of creating flood maps, ascii grids and time series results.
Using industry standard methods, Damage Calculator uses depth grids for different return periods and combines them with property datasets and depth-damage data to calculate the damage for each property affected by flooding. Using this data, you can obtain the total damage for each flood event with the option to also calculate average annual damages (AAD) and, for a user specified timeframe, present value damages (PVD) values.
You can also specify your own depth damage data and currency to ensure calculations are appropriate to your specific geography or location.
The tool allows you to specify whether threshold levels should be applied to the properties. These protection levels are used to calculate the economic benefits of the different considered options to help manage or reduce the risk of flooding.
In addition, Damage Calculator can also estimate the risk to life. Apart of depth grids, it uses time of inundation and hazard rating grids, along with a reference value for loss of life to estimate damages associated with risk to life during a flood event.
