High-energy nearshore processes High-energy nearshore processes

The problem of shoreline erosion has become a matter of much interest in the recent press. To some extent this interest has been driven by the slow rise in sea level that has lent an air of inevitabilty to matters. However, the discussions certainly become more focused by the approach of a major storm or hurricane: for instance, the 1985 scare associated with Hurricane Gloria. In fact...

Some Techniques for Reducing Landslide Hazards Some Techniques for Reducing Landslide Hazards

Many techniques are available for reducing landslide hazards; 27 are described in this paper. Prerequisites for the successful use of these techniques are hazard information understandable to nongeologists and adequate communication of this information to those who will, or are required to, use it. It is concluded that certain factors needed to ensure the lasting effectiveness of these...

Alternate forms of the associated Legendre functions for use in geomagnetic modeling. Alternate forms of the associated Legendre functions for use in geomagnetic modeling.

An inconvenience attending traditional use of associated Legendre functions in global modeling is that the functions are not separable with respect to the two indices (order and degree). In 1973 Merilees suggested a way to avoid the problem by showing that associated Legendre functions of order m and degree m+k can be expressed in terms of elementary functions as Pmm+k(θ)=sinm(θ)∑ki...
