Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...
Advisory and Mitigation Activities in the Carolinas
To effectively reduce losses from hazard occurrences, an active and agressive mitigation program is needed. Following Hugo, several important activities have been initiated, utilizing...
Bedload Transport Under Low Frequency Waves
The concept of a bedload spectrum, showing the distribution of energy with frequency in the bedload process, is proposed. The bedload process is thus analysed in the frequency rather than...
