Multifractal characterisation of overland flow of nature-based solutions scenarios

The standard method for characterizing the variability of overland flow focuses primarily on a single scale, usually the smallest scale available (i.e. the highest resolution). However, the extremes of overland flow are generally variable over a wide range of scales. Thus, the smallest scale has no...

Description
Summary:The standard method for characterizing the variability of overland flow focuses primarily on a single scale, usually the smallest scale available (i.e. the highest resolution). However, the extremes of overland flow are generally variable over a wide range of scales. Thus, the smallest scale has no specific hydrological significance, and a scale-independent characterization is more physically relevant. This study investigated the spatial variability of overland flows and evaluated the hydrological performance of the Nature-Based Solutions scenarios in terms of a possible improvement of the morphological functioning of the catchment at several scales.
