WebbAbstract. The unit hydrograph (UH) has been one of the most widely employed hydrological modelling techniques to predict rainfall–runoff behaviour of hydrological catchments, and is still used to this day. Its concept is based on the idea that a unit of effective precipitation per time unit (e.g. mm h−1) will always lead to a specific catchment response in runoff. … Webbför 2 dagar sedan · Since no candidate for Denver mayor received more than 50% of the vote, the top two vote-getters, Mike Johnston and Kelly Brough, will go head-to-head in a June 6 runoff election.
