In these days, many Asian countries are rapidly developing according to their fast growing economies, which often cause considerable environmental changes around water bodies such as lakes, reservoirs and lagoons. Remote sensing technology can be integrated in long-term studies, both retrospective and predictive, in order to anticipate degradation and to take mitigating measures at an early stage on these water environments. This book attempts to propose new approaches to monitor water environments using satellite remote sensing data and those methods will give contributions to various...

To understand nature is to describe it in proper methods. Here, we consider human or human activity is a part of nature. When we find out how things are occurring in natural or human world, it must be described in a suitable way. In most cases, we cannot describe whole nature exactly as it is, because nature looks too much complicated on the whole.

By modeling, we cut off many things which are not important in the context of...
