Generalized hydrology of prairie potholes on the Coteau du Missouri, North Dakota
William Stewart Eisenlohr, Charles E. Sloan
1968, Circular 558
This report presents all the information, obtained during the investigation, that lends itself to generalization. It describes conditions on that part of the Coteau du Missouri where there is little integration of drainage systems. The surface of the glacial drift in this region is dotted with shallow depressions known as...

1968, Water Supply Paper 1757-J
For much of Kordofan Province, surface-water supplies collected and stored in hafirs, fulas, and tebeldi trees are almost completely appropriated for present needs, and water from wells must serve as the base for future economic and cultural development. This report describes the results of a reconnaissance hydrogeologic investigation of the...
Reconnaissance investigations of the discharge and water quality of the Amazon River
Roy Edwin Oltman
1968, Circular 552
Selected published estimates of the discharge of Amazon River in the vicinity of Obidos and the mouth are presented to show the great variance of available information. The most reasonable estimates prepared by those who measured some parameters of the flow were studied by Maurice Parde, who concluded that the...
