Repository accompanying the manuscript "Rhine flood stories: Spatio-temporal of historic and projected Rhine River flood formation'.

The genesis of riverine floods in large river basins often is complex. Streamflow originating from precipitation and snowmelt and different tributaries can superimpose and cause high water levels threatening cities and communities along the river banks. In this study, we capture and share the story behind major historic and projected streamflow peaks in the large and complex basin of the Rhine River. Our analysis is based on hydrological simulations with the mesoscale Hydrolgical Model (mHM) forced with an ensemble of climate projections. The spatio-temporal analysis of the flood formation includes the assessment and mapping of antecedent liquid precipitation, snow cover changes, generated and routed runoff, quantile extents (i.e., the fraction of upstream grid cells that generate streamflow above a long-term quantile) and the above-average runoff from major sub-basins up to ten days before a streamflow peak.

This repository holds all result figures exported for the investigated streamflow peaks at gauges Cologne, Kaub, Worms and Speyer. Furthermore, we provide a Docker image with a web application that enables the interactive investigation of all runoff peaks.
