Understanding and modeling the determinants of extreme hourly rainfall intensity is utmost importance for management flash-flood risk. Increasing evidence shows that mesoscale convective systems (MCS) are principal driver in United States. We use value statistics to investigate relationship between MCS activity Greater St. Louis, an area particularly vulnerable flash floods. Using a block maxim...

The effects of spatial variability rainfall, geomorphology, and climatology precipitation temperature on the hydrologic response remain poorly understood. This study characterizes catchment in terms a variable called flashiness, that describes severity flood as rate rise unit discharge. It overcomes limitations prior works based limited case studies or simulations by gathering information basin...
