The morphology, processes, and evolution of Monterey Fan: a revisit The morphology, processes, and evolution of Monterey Fan: a revisit
Long-range (GLORIA) and mid-range (TOBI) sidescan imagery and seismic-reflection profiles have revealed the surface morphology and architecture of the complete Monterey Fan. The fan has not developed a classic wedge shape because it has been blocked for much of its history by Morro Fracture Zone. The barrier has caused the fan to develop an upper-fan and lower-fan sequence that are...

The potential for water savings through the control of saltcedar and Russian olive: Chapter 3 The potential for water savings through the control of saltcedar and Russian olive: Chapter 3
This chapter discusses the components of the water budget for a riparian system containing large stands of saltcedar or Russian olive—that is, how water is used by the plant community and how that use affects both streamflow volume and groundwater levels. The relation of water availability to the hydrologic cycle and geomorphic setting in the Western United States, as well as the...

The tectono-stratigraphic framework and evolution of southwestern Maine and southeastern New Hampshire The tectono-stratigraphic framework and evolution of southwestern Maine and southeastern New Hampshire
Five belts of metamorphosed sedimentary and volcanic rocks underlie southwestern Maine and southeastern New Hampshire: Middle Ordovician Falmouth-Brunswick sequence; Middle and Late Ordovician Casco Bay Group, and Late Ordovician to Early Silurian rocks of the Merribuckfred Basin; Late Ordovician to Early Silurian rocks of the East Harpswell Group; Silurian to Early Devonian rocks of the...

Tree-ring dated landslide movements and seismic events in southwestern Montana, USA Tree-ring dated landslide movements and seismic events in southwestern Montana, USA
Because many tree species can live for several centuries or longer (Brown 1996), tree-ring analysis can be a valuable tool to date geomorphic events such as landslides, earthquakes, and avalanches in regions lacking long historical records. Typically, a catastrophic landslide will destroy all trees on the landslide, but trees on slower moving landslides may survive. For example, the...

Water-budget methods Water-budget methods
A water budget is an accounting of water movement into and out of, and storage change within, some control volume. Universal and adaptable are adjectives that reflect key features of water-budget methods for estimating recharge. The universal concept of mass conservation of water implies that water-budget methods are applicable over any space and time scales (Healy et al., 2007). The...

Wildlife underpasses on U.S. 64 in North Carolina: integrating management and science objectives Wildlife underpasses on U.S. 64 in North Carolina: integrating management and science objectives
This chapter on wildlife underpasses on U.S. Highway 64 in North Carolina is from a book on highways, wildlife, and habitat connectivity. U.S. 64 is an important route in North Carolina connecting major population centers and highways that underwent a major upgrade from a two-lane rural road to a major highway. New routes were proposed for a large portion of the project (28 miles) to...
