A field inspection methodology, a scour- susceptibility ranking procedure, and a data base management system were developed for the Missouri Highway and Transportation Department to use for scour inspection and assessment at bridges throughout the State. Because scour can cause bridge failure, federal statute mandates that the approximately 4,700 state-owned bridges over water be...

Determining the rheologic properties of coarse- grained mass flows is an important step to mathematically simulate potential inundation zones. Using the vertically rotating flume designed and built by the U.S. Geological Survey, laboratory procedures and subsequent data reduction have been developed to estimate shear stresses and strain rates of various flow materials. Although direct...
