Pilot study for collection of bridge-scour data
R.D. Jarrett, J. M. Boyle
1986, Water-Resources Investigations Report 86-4030
Scour around bridges is a serious problem on many rivers; bridge failure often is attributed to undermining of piers or abutments by scour. A pilot study was made at four bridge sites in Colorado to develop and test guidelines for collecting scour data onsite during high flows. These guidelines potentially...

Leachate migration from an in situ oil-shale retort near Rock Springs, Wyoming
K. C. Glover
1986, Open-File Report 85-575
Geohydrologic factors influencing leachate movement from an in situ oil shale retort near Rock Springs, Wyoming, were investigated by developing models of groundwater flow and solute transport. Leachate, indicated by the conservative ion thiocyanate, has been observed 1/2 mi downgradient from the retort. The contaminated aquifer is part of the...
