Determination of discharge during pulsating flow
T. H. Thompson
1968, Water Supply Paper 1869-D
Pulsating flow in an open channel is a manifestation of unstable-flow conditions in which a series of translatory waves of perceptible magnitude develops and moves rapidly downstream. Pulsating flow is a matter of concern in the design and operation of steep-gradient channels. If it should occur at high stages in...

Potential for potash and other evaporite mineral resources in West Pakistan
C.L. Jones
1968, Open-File Report 68-153
Reconnaissance examination of marine evaporites in West Pakistan has revealed a highly favorable resource situation with respect to anhydrite, and a potentially favorable position for potash and sulfur. Further work is needed to evaluate the preliminary interpretations made during the present study. The establishment of a potash resource organization within...

Redefinition of the terms Kingsport Formation and Mascot Dolomite and subdivisions of the upper part of the Knox Group in eastern Tennessee
Leonard Dorrean Harris
1968, Open-File Report 68-119
Upper part of the Knox Group has previously been divided into three formations; however, because of the lack of regionally recognizable boundaries, there has been a marked inconsistency as to the rocks assigned by different workers to the Longview Dolomite, Kingsport Formation and Mascot Dolomite. Regional stratigraphic studies have pointed...
