4.9.5 Monitoring Site
The profile of monitoring site can be loaded from the maps. The retrieving form of monitoring site consisting of some information’s about the locations administration
and geography coordinate is shown in Figure 72.

4.9.6 Evaluation of River Pollution Status
In the spatial format, the river pollution was represented by monitoring site. The status of pollution in the river depends on the pollution analysis of each monitoring site.
Therefore, the distribution of river pollution status in the maps could be described as
shown in Figure 73.

4.9.7 Evaluation of Industrial Pollution Status
The systems perform the spatial analysis for distribution of polluted industries as
shown in Figure 74. According to the analysis, some industries marked by red balls,
while the white balls represent unpolluted industries.

4.9.8 Searching The Potential Polluted Industries
By using spatial analysis, the system can do the searching of the potential polluted industries. It is called potential, because many factors cause the decrease of river water
102 quality. Therefore, further investigations are needed to decide whether the industry is
polluted or not. The concept of spatial analysis is very simple. Only industries located in a certain
distance from the polluted river with an altitude higher than the monitoring site are
indicated as the potential polluted industries Figure 75.
Figure 75 . Input The Predicted of Polluted Area Radius in Km’s
For instance as shown in Figure 75, the searching of potential polluted industries at a
radius of 5 km from the monitoring site position resulted in five potential polluted
industries Figure 76.

4.9.9 Distribution of BOD source
Distribution of BOD Biological Oxygen Demand by source can be approached
using distributed populations. Figure 77 shows the distribution of BOD source which is
useful for developing the environmental programs.
