Transient Seepage In A Variably Saturated Levee: Laboratory Testing, Field Monitoring And Numerical Modeling, Xavier Arnaldo Rivera-Hernandez
Transient Seepage In A Variably Saturated Levee: Laboratory Testing, Field Monitoring And Numerical Modeling, Xavier Arnaldo Rivera-Hernandez
Theses and Dissertations
Several hydraulic loadings impose earthen levees to time-dependent variably saturated seepage conditions. The main objective of this study is to improve the analysis of levees under transient seepage with the use of unsaturated soil mechanics. An extensive set of laboratory testing, field monitoring and numerical modeling are performed to analyze a silty sand setback levee located near Seattle, WA. In-situ data obtained from field monitoring are used to monitor suction and effective stress within the levee’s embankment and foundation over the past two years. Soil samples taken from the site are used to perform index, water retention, and unsaturated multi-stage …
Assessing Tsunami Risk In Southwest Java, Indonesia: Paleo-Tsunami Deposits And Inundation Modeling, Han Deng
Assessing Tsunami Risk In Southwest Java, Indonesia: Paleo-Tsunami Deposits And Inundation Modeling, Han Deng
Theses and Dissertations
Samples from 13 different sites along the south coast of West Java yield 7 candidate paleo-tsunami sands, which may represent 4 different paleo-tsunami events. Ages obtained from one deposit may document a tsunami and coastal subsidence from an earthquake in 1,053 AD. The tsunami deposit from this event is preserved in an uplifted marine terrace exposed at Panto Cape, Banten Province. We speculated that the terrace has been uplifted about 4.6 m to the present height of 2 m above sea level, since the 1053 AD event at a rate of 4.8 mm/a. This uplift is strong evidence that strain …
