This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three important topics have been studied in this dissertation. First, the effects of deep soil deposits of the Mississippi embayment in ground motion amplification have been studied. Using the results of one-dimensional analyses, a parametric model is developed for the region to estimate the ground motion amplification. The averaged shear-wave velocity in the upper 30 meter, Vs30, ranging from 220 to 800 m/s and deposit thickness varying from 70 to 750m, are considered in the estimation of the ground motion amplification with respect to a generic bedrock profile of the Mississippi embayment. Results indicate that site factors suggested by seismic codes cannot capture the site properties of the Mississippi embayment and are not appropriate for the region. In the second part, a new step-by-step method is developed to select a set of ground motions which takes into account a site-specific Probabilistic Seismic Hazard Analysis (PSHA) and the associated uncertainties through the defined logic tree. In the proposed method, after capturing the variability of the Uniform Hazard Response Spectrum (UHRS), I used a Monte Carlo procedure to produce a set of response spectra that has mean equals to the target and variability close to the variability of the target at all the spectral periods. Each member of the generated set is called individual target response spectra, and ground motions from the database of real data and also synthetic ground motions are selected based on their similarity with the individual target response spectra. The method’s procedure is defined through studying a sample site in North of the Mississippi embayment.In the last part of the study I developed a model for the ratio of Vertical to Horizontal component of earthquakes (V/H ratio) for the Mississippi embayment. This model can be used in developing the site-specific vertical design spectrum for the region by scaling the horizontal design spectrum resulting from a PSHA. The input parameters of the applied functional form are magnitude, distance, and Vs30. The proposed model has the advantage of including site response of the study area.

Excerpt: ...Mississippi and southern Tennessee. As shown in figure 1A, most of the Mississippi Alluvial Plain is a predevelopment discharge area for the five studied aquifers. The zone that had the largest predevelopment discharge, also in the northern area, was in the Mississippi Alluvial Plain east of Crowleys Ridge where the upper Claiborne aquifer subcrops the Mississippi River Valley alluvial aquifer. For the majority of this area, discharge to the alluvial aquifer was more than 0.2 in./yr, and in a small area (about 100 mi2) west of Memphis discharge from the upper Claiborne aquifer was more than 0.6 in./yr. Possible explanations for this large recharge and discharge in the northern area are (1) the middle Claiborne aquifer has large transmissivity, (2) the embayment is narrow and thus flow paths from recharge points to discharge points are shorter, and (3) high heads in the aquifer outcrop areas produce correspondingly higher heads in individual aquifers under the Mississippi Alluvial Plain, forcing flow upward into the upper Claiborne aquifer and thence into the Mississippi River Valley alluvial aquifer. Before development, aquifer outcrop areas in the eastern and western areas had more than 0.2 in./yr recharge in the upland areas of central Mississippi, south-central Arkansas, and northwestern Louisiana, but most of the outcrop areas had less than 0.2 in./yr recharge (fig. 1A). Predevelopment discharge from the aquifer system in the eastern and western areas was predominantly to the Mississippi River Valley alluvial aquifer, but some discharge was to large rivers and valleys. The Mississippi River Valley alluvial aquifer, which underlies the Mississippi Alluvial Plain, received as much as 0.2 in./yr discharge from the subcropping aquifers...
