Assessing Chinese flood protection and its social divergence

A Mathematical Model for Flood Protection

Many regions in the world are protected against flooding by a dike, which may be either natural or artificial. We deal with a model for finding the optimal heights of such a dike in the future. It minimizes the sum of the investments costs for upgrading the dike in the future and the expected costs due to flooding. The model is highly nonlinear, nonconvex, and infinite-dimensional. Despite this...

Flood protection and management: quo vadimus?

In the last decade, there have been many destructive floods in various parts of the world. Despite the extensive investment in flood control works, neither flood occurrences nor damages are decreasing. A possible consequence of climate change is an increased frequency of extreme meteorological events that may cause floods. Discussion is offered of some recent large floods in the world and of th...

Online Social Media Networking and Assessing Its Security Risks

Over the past several years, we have seen the emergence of new paradigm in the Internet, online social media networking, which provide Internet users to communicate and collaborate with family, friends, social groups, and other community by using social media tools (i.e., Twitter, Facebook, MySpace, and Youtube). The use of social media for communication is becoming more prevalent worldwide, wi...

Flood Modeling System and Its Parallelization

Flood modeling is a complex problem that requires cooperation of many scientists in different areas. In this paper, the architecture and results of ANFAS1 (Data Fusion for Flood Analysis and Decision Support) project is presented. This paper also focuses on the parallel numerical solutions of flood modeling module that are the most computationalintensive part of whole ANFAS architectures.
