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?

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
Stream flow
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
Webcams
Soil moisture
Data layers:What do those river levels mean for where I live?
Analyse historical images
“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

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”
