Open Source Software for Preprocessing GIS Data for Hydrological Models

For many studies models are used or developed. During modelling courses not much attention is paid to the preprocessing of input data and parameters needed for the models. A lot of open source software is available for this purpose. Besides desktop tools with graphical user interfaces, scripting is very useful for processing large datasets and timeseries. With the skills learned in this course you will be able to more efficiently process your data and setup and improve your models.

Visualising disaster with Team Thailand

Poramate Minsiri, an internet pioneer in applying technology to disaster relief, is setting up interactive maps for monitoring natural disasters.

Calling the effort Team Thailand, the founder of the Kapook portal and thaiflood.com also hopes the maps will eventually help keep tabs on crime in the country.

Lake Sakakawea and Lake Mead Water Resources and Disasters

Current regional and global scale hydrological models, such as the Coupled Routing and Excess STorage (CREST) model, do not take into account the release and storage of water by man-made dams. These models make gross assumptions about dam operation, impairing their accuracy and utility. In many less economically developed areas of the world, it is not possible to acquire information on the timing and extent of water release in dammed regions.
