Derived segments for selected classes (see figs. 2) are 
integrated into the GIS software as vectorized class data. By 
means of the MAPINFO 7.0 software, sub-segments in 
relation to the each class are combined, thus template for 
each class is created (Fig.3a, 3b and 3c) By the 
superimposition of 2003 spotS image onto the vectorized 
images relevant to the 1983, 1992, and 2000 for the changes 
in the river-bed and delta, visual structure has been generated 
(Figs.4a,4b and 4c). 
Areal changes in rivebed and delta and the area with the 
dimension at 20 km? between 1983 and 2003 have been 
analysed based on the GIS 
4. CONCLUSION 
Undertaken study has reached to following results related to 
the GIS-based temporal analysis of changes Filyos in the 
river and its delta over 20 years with the help of classification 
of remotely-sensed images. 
e Temporal changes over the Filyos valley and 
its sea ad joint have been analysed by GIS 
172 
and acquired results are given in Fig.5 
graphically. 
e In the area between the delta to Southside 
with 20 km? corridor, length and dry areas of 
river has been evaluated temporally and 
amount of changes are represented over the 
graphic given in Fig.6 
e Specifically, important decrease has been 
observed in the dimension of river delta. In 
1984, river falls into the sea from two 
different locations, however, at present this is 
happening only from one location. 
e Increase in the size of mass are as which 
contains alluvion material and located in the 
river-bed and delta mainly depends on the 
facts of floods happened in 1990 and the 
conversion of forested areas into the 
agriculture lands.
