Executive Summary Based on the 2000 Record of Decision, an explicit goal of the California Bay-Delta Program is to stabilize and maintain the current configuration of channels and islands in the Delta. This effort is based on the conclusion that hydraulic integrity of the Delta is necessary for meeting water supply, water quality and ecosystem restoration objectives. Landscape level simulations...

Levee slides may result in catastrophic damage to the region of failure. Remote sensing data, such as synthetic aperture radar (SAR) images, can be useful in levee monitoring. Because of the long length of a levee, the image size may become too large to use computationally expensive methods for quick levee monitoring, so time-efficient approaches are preferred. The popular support vector machin...

The article is both a survey of the literature since publication in 1997 Gottfried Schramm’s book, and critical review conclusions drawn by most recent research. focuses onthe main theses put forward Schramm (his famous eight on Romanian ethnogenesis) way they fared literature. His 1985 1986 articles, which formed basis book’s fourth part have been translated into Hungarian Romanian. However, t...

In view of the heightening and thickening levee project which already built, settlement deformation on top landside slope cracks were investigated. The finite element method was used to simulated levee. results show that after thickening, thickness new filled soil is uneven in cross-sectional direction levee, resulting a significant difference distribution additional stress settlement. addition...

In this report, I talk about my work on fluid simulation and erosion simulation. First some background knowledge about both fluid and hydraulic erosion simulation is discussed and then some technical details about a levee erosion simulator is presented. Some implementation results of the system are also presented and discussed. Finally, I will also discuss the difficulties I faced when doing th...

Intensive anthropogenic disturbances have affected the channel of the middle Yangtze River since the 1950s. This paper selects the Jianli reach as an example to examine human impact on channel change in the middle Yangtze River. 1:100,000 channel distribution maps from 1951, 1961 and 1975 and 1:25,000 navigation charts from 1981 and 1997 were employed to reconstruct channel change in the study ...

Most coastal structures have been built in surf zones to protect coastal areas. In general, the transformation of waves in the surf zone is quite complicated and numerous hazards to coastal communities may be associated with such phenomena. Therefore, the behavior of waves in the surf zone should be carefully analyzed and predicted. Furthermore, an accurate analysis of deformed waves around coa...
