The september 2013 flood: what we saw and what it might mean...) from one watershed to the next?-For the bridges that survived the initial peak flood event, what actions then needed to take place to get the bridge serviceable again?-What crucial and irreplaceable observations did we collect (or fail to collect) that have since proved crucial in order to help future researchers reconstruct the peak flow estimates and to calculate new proposed regulatory flows?-How did scour at highway bridges actually present itself, and does that line up with the current accepted practices of scour estimation during design?My sincere hope is that this topic would be of interest to practicing hydraulic engineers that design, help construct, and maintain highway infrastructure...

Scour and fill in ephemeral streamsThe classical concept that mean bed elevation over an entire stream reach is lowered by scour during flood-wave passage and is restored by deposition in the waning flood phase (mean-bed scour and fill) can be challenged...
