Data-driven flow forecasting models, such as Artificial Neural Networks (ANNs), are increasingly used for operational flood warning systems. In this research, we systematically evaluate different machine learning techniques (random forest and decision tree) compare them with classical methods of the NAM rainfall run-off model Vésubie River, Nice, France. The modeled network is trained tested using discharge, precipitation, temperature, evapotranspiration data about four years (2011–2014). A...

Abstract Accurately delineating both pluvial and fluvial flood risk is critical to protecting vulnerable populations in urban environments. Although there are currently models frameworks estimate stormwater runoff predict flooding, often minimal observations validate results due the quick retreat of floodwaters from affected areas. In this research, we compare contrast different methodologies for capturing extent order highlight challenges inherent current methods flooding delineation. This...

The alteration of natural land cover to impervious surfaces during development increases stormwater runoff. Stormwater Control Measures (SCMs) are used manage water quantity and enhance quality by restoring the hydrologic cycle altered development. Often, SCMs have an outflow pipe handle overflows or release detained when infiltration is not possible. Traditionally, these static controls (e.g. a small orifice restrict volume outflow), however, systems can be improved instituting real-time...
