... or to coastal slope, and suggest that instead, collection history most likely tracks actual fossil productivity. Land management practice to install riprap rock barriers to mitigate coastal erosion is effective at reducing exposure of fossils at the decadal scale, thereby meeting the avoidance criterion...

...DAVID A. LIENHART Abstract The quality of riprap and armor stone for a particular project is occasionally determined through the use of ambiguous and subjective specification requirements. These requirements are often unrelated to true rock quality and result in placement of stone of unknown...

...WILLIAM P. STAUB Abstract This paper presents a methodology for determining the magnitude of oversizing required for marginal quality riprap. Riprap is often used to protect earth cut and fill structures from erosion. Erosion protection of uranium mill tailings embankments, caps, and drainage...
