Map showing landslides and areas of potential landsliding in the Salina quadrangle, Utah Map showing landslides and areas of potential landsliding in the Salina quadrangle, Utah
The term “landslide” is broadly defined as any “downward and outward movement of slope-forming materials composed of natural rock, soils, artificial fills, or combinations of these materials. The moving mass may proceed by any one of three principal types of movement: falling, sliding, or flossing, or by their combinations” (Varnes, 1958). Landslides and areas of potential landslides are...
Map showing length of freeze-free season in the Salina quadrangle, Utah Map showing length of freeze-free season in the Salina quadrangle, Utah
In general, long freeze-free periods occur at low elevations, and short freeze-free periods occur at high elevations. But some valley floors have shorter freeze-free seasons than the glancing foothills because air cooled at high elevations flows downward and is trapped in the valleys. This temperature pattern occurs in the western part of the quadrangle in Rabbit Valley, Grass Valley...
Map showing ranges in probable maximum well yield from water-bearing rocks in the San Francisco Bay region, California Map showing ranges in probable maximum well yield from water-bearing rocks in the San Francisco Bay region, California
This map presents generalized information regarding the probable maximum yields of wells in the rocks of the San Francisco Bay region. It is intended to serve the needs of planners and other persons seeking general information on potential yields from water wells. Four ranges in probable yield, based on adequacy of the range in yield for major beneficial uses of water, are given. The...
