How can information technology help me understand the risks from flooding? 1.What information is available at a local level in order that I can decide when my property is at risk from flooding? 2.How might flood risk change in future (climate, land use etc)? How does land management interact with the likelihood of flooding? 3.Can you help me interpret this information? Is any of this certain? Your Catchment Tarland
How do I decide if my property is at risk from flooding? Upload info What do you think? “We aim to make real-time, locally-relevant data accessible through the web for communities to become better informed about their environment”
Rain gauges Webcams Soil moisture Data layers: Where and what are the data sources ? River Dee Tarland Aboyne “River level data is an example of what can be readily achieved now live on the web and, given appropriate interpretation, can be highly informative about water quantity and quality questions from communities”
What are you interested in? Forecast River Dee Rain gauges Stream flow Soil moisture Data layers: What do those river levels mean for where I live? “Flood extent analysis from web cam images can be used to calibrate data for current (river levels), recent (soil moisture) and near-future (rain forecasting) conditions. Together this system will ‘learn’ to improve local flood predictions”
Scenario 1: Climate change affects runoff Scenario 2: A change in land management occurs here What does this mean? Animate prediction Your Flood risk prediction #1 Chance of this area flooding? Use Slider What does this mean? Mouse over graph Very High Very low Can the system learn what the future holds as the catchment land use and climate changes? “A goal is for scientific models to be applied in the background to aid future predictions with respect to changes in climate, land use and management. These results will simply be displayed on a probability basis”
Who is going to help me if I don’t understand it? My house! “Online tools will help select levels of user interpretation with explanatory graphics and video files. There will be a link through the local website to the national Environmental Virtual Observatory web portal” What does a 100 year flood mean?
