Condition Survey: Mather Air Force Base, California

"The purpose of this report is to present the results of a condition survey performed at Mather Air Force Base (MAFB), California, during 31 October-3 November 1972. The two major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements and the condition of pavement repairs and the types of maintenance materials that have been used at this airfield" (p. 1).

Graphical Method for Estimating Occurence and Duration of a Critical Low Flow in the Sacramento River at Freeport, California

Abstract: Sacramento County expected to begin operation of the Sacramento Regional Wastewater Treatment Plant in 1982. The California State Water Resources Control Board has ruled that the plant will not be allowed to release effluent into the Sacramento River when flow in the river is 4,000 cubic feet per second or less. Depending on tide condition, flows less than 4,000 cubic feet per second may occur either once or twice during each 24-hour 50-minute tide cycle when the daily mean flow is less than about 12,000 cubic feet per second. Daily mean flows less than 12,000 cubic feet per second occur about 28 percent of the time. Riverflow at the plant outfall is monitored by an acoustic streamflow measuring system. Regulation of effluent released from the plant will normally be based on real-time flow data computed by the acoustic system. A graphical method for determining the occurrence and duration of flows of 4,000 cubic feet per second and less was developed as a backup system to be used if a temporary failure in the acoustic system occurs.
