9.3.4 Monitoring of Spatial Heterogeneous Water Systems

One of function of expert systems described in Chap. 8 is the spatial image
reconstruction based on the data that are episodic in the time and fragmentary in the
space. A speci

c case of the ESECEZ system is considered for the monitoring of
Nuoc Ngot Lagoon located in South Vietnam (Binh Dinh province, Fig. 9.20 ). The
Lagoon is located at the latitude and longitude coordinates of 14.15N and
109.183333W, respectively. This lagoon is used for fishing and it is located in the
zone with growing intensive agriculture and industry. Its basic characteristics are
given in Table 9.16 .
Hydrophysical investigations in the lagoon zone were accomplishes in the frame
of the Russian-Vietnamese collaboration in the ecoinformatics problems. Lagoon is
divided in three levels by depth (upper, middle and near-bottom). The following
characteristics were registered: direction and speed of currents, salinity, turbidity,
phytoplankton biomass, zooplankton biomass, zoobenthos biomass. The scheme
and the procedure of the in situ measurements are given in Fig. 9.18 and Table 9.17 .
