From Oct. 8 to Oct. 10, Laurie BOITHIAS (CNAP, GET) offered a hydrological modelling training with SWAT+ (Bieger et al., 2017). The objective for the participants was to learn how to use the tool and get basic knowledge of numerical modelling. The training lasted 3 days. The attendees first implemented the tool by using long term data from the Houay Pano critical zone observatory. They then handled input and output files (time series, maps), and eventually implemented the model on their own catchment. The training was given in Luang Prabang, Laos, in the meeting room of the Provincial Department of Agriculture and Forestry. It was funded by IRD and M-TROPICS CZO. Ten participants (IRD staff, partners, PhD students) came from Laos, Vietnam, Cambodia, and France.
