We provide a 3-day course providing a combination of theoretical knowledge and hands on computer instruction. This course is ideal for beginners, or for those who wish to freshen up or sharpen their existing modelling skills. This course is especially focused on teaching users ‘how to model effectively’ using state-of-science methods. It teaches fundamental skills and rule of thumb choices. The mornings are dedicated to theory and the afternoons to hands on computer training. The purpose of the course is to leave with a good sound general knowledge of how to use and interpret these models.
