Flood prediction is essential in risk assessment to mitigate damages to population and goods. It has been traditionally addressed with physically-based methods, involving catchment-scale hydrological models to predict rainfall-induced runoff. These models need careful calibration of parameters, (e.g. Manning coefficient), but the lack of detailed information often leads to the use of simplifications which affect the accuracy of the results. They also require high computational resources and time, which prevents their use in real-time situations. By contrast, there is an increase in available information regarding discharge in different locations in many catchments, with increasing frequency of data acquisition and reliability. This, together with the development of machine learning algorithms, raised the interest in applying data-driven methods in this field, as proven by recent publication records.
The objective of the research is the development of a methodology for predicting flood discharge combining machine learning and physically-based methods (Iber software). This stems from the background of the proposing groups: while that of Machine Learning in Civil Engineering has a relevant background in applying machine learning in different areas, with focus on dam safety, Flumen leads the development of the Iber software, a standard in hydrological and hydraulic modelling. A preliminary initiative on the combined use of both techniques (neural networks in that case) dates from 2003, in the Ramflood European project. The idea fits with the research line in Water in the Generalitat-CIMNE Framework Programme.
