![]() ![]() The lesson objectives include the following: Using the tools (models and scripts) and the sample dataset provided, you will model and predict flood consequences for a series of simulated storm water events. Many residential homes and other critical infrastructure are located within landscape sinks that are filled during a rainstorm, thus flooding homes and affecting roads and rail tunnels. In this lesson, you will explore a drainage basin north of Copenhagen, Denmark, that has been severely impacted. Where building footprints are available, these may be incorporated into the digital terrain model from the beginning, thereby allowing the model to predict impacts on infrastructure and other land uses.įor an introduction to bluespot modeling, review Coping with Cloudbursts. Model predictions explored in these lessons are based on the screening of a digital terrain model for landscape depressions within a drainage basin, their hierarchical downstream locations, and how they fill up and spill over during simulated uniform rainstorms while ignoring local infiltration rates and time. These lessons replace and build on an older set of tools and lesson and incorporate hierarchical downstream spillover. ![]() The aim of this series of lessons (organized as modules) is to predict flood risk assessment due to storm water incidents and to consider where to avoid future site developments while considering the effect of future climate changes. Up, causing thousands of basements to be flooded with a mixture of It puts a special emphasis on flood risk: A bluespot is an area likely to fill or overflow in a storm water situation, endangering structures located within or near it.Ĭopenhagen, Denmark, was hit with 136 millimeters of rain (nearly 5 Contents Overview Requirements Outline Explore the tools and data Bluespot modeling - setup Bluespot modeling - model tools and data Bluespot modeling – data requirements and workflow Run the model and tools Inspect the sample data Review the model and tools Run the Identify Bluespots Features model Update layer symbology Investigate attributes Explore streams Create nodes and edges Prepare spillover fields Spillover Batch Filled Events Explore the results Explore Bluespots, BluespotWatersheds, Nodes, and Stream features Investigate filled events and buildings layer intersections Update layer symbology Create a chart Map the bluespot spillovers Map the stream spillovers using graduated colors and graduated symbols Apply graduated symbology Map the bluespots’ depths Challenge - Identify additional locations susceptible to flooding Run the analysis with your own data Prepare your own data - elevation model considerations Data preparation - set up your bluespot project Data preparation - derive a drainage basin Data preparation - add buildings to DTM (optional) Data preparation - burn flow lines onto the DTM Execute the Assembled Bluespot Workflow model Acknowledgements Ready to learn more?
