Vietnam has the coastal line equaled 3,260 km. There are many estuaries and
lagoons on the seashore of which the development of anthropogenic systems
depends on the sea water quality. At the same time these systems generate the
pollutants and contaminate the sea. The pollutant sources in the Vietnam are
grouped by following
five classes (Bui Ta Long 1999; Bui Ta Long et al. 2010):
(1) agricultural sewage;
(2) domestic, municipal and industrial wastes;
(3) shipping;
(4) aquaculture; and
(5) coastal minings.
These sources are combined on the territories bordered to the South-China Sea.
That is why the synthesis of environment monitoring system to assess the water
quality in the estuary zone requires a systematic approach. A short description is
given below about the expert system for ecological control of estuary zone
(ESECEZ) developed in framework of collaborative agreement between Russian
Academy of Sciences and the Vietnam Academy of Sciences and Technology on
the ecoinformatics and remote sensing (Cao Van Phuong 2009a, b, 2012).
The expert system is based on the combination of modeling technology, algo-
rithms of space-time reconstruction of measurement data and computer visualiza-
tion software Block-diagram of expert system is given in Fig. 9.7 and Table 9.6 .
The ESECEZ is oriented on the processes study of regulating and controlling the
release of potential hazardous chemicals into the typical for the Vietnam estuary
environment. The main functions of expert system can be realized automatically,
but not the human components. Human activity can be displayed when it is required
to explain the ecological situation or to make decisions about how to protect the
environment.
