The regulations created by the Water Board Authority 
have determined four types of protected areas around 
dams: 
very near, 
near, 
medium and far distance 
protected areas. According to the regulations industrial 
activities were 
prohibitied or resticted within the boundaries of four types 
of protected areas. Only in the far distance protected 
zone, a very low density of single family housing was 
activities, 
permitted (Orhon, 
housing, 
1991). 
Today, 
and agricultural 
several 
industrial 
activities and illegal housing are located within the 
protected areas of the Elmali water basins. Figure 3 
shows that digitized protected area borders and Table 1 
indicates a list of their square kilometrage

2.1. Objectives 
In this study, image processing and change detection 
analysis have been done by interpreting multitemporal 
images. The analysis consists of four major steps. 
These are: 
1- The Water Basin area protection zones have been 
digitized using 1/25000 scaled Standard Topographic 
Maps. 
2- Satellite images have been registered to a known map 
coordinate system. 
3- For the selection of the traning areas, a land study has 
been carried out and maps and plans belonging to the 
area utilisied. In addition, Merge images and aeria 
photographs have been used for this stage. 
4- The supervised classification method has been applied 
to the Landsat images in order to determined the land 
use. In addition, temporal variations and accuracy 
assesments have been examined. 
2.2. Material 
The monitoring of changes of the Earth's surface through 
the use of images recorded on several different dates 
(multitemporal analysis) has been important for studies 
of landuse characteristics. (Durury 1987; Ormeci 1994). 
The images and the necessary material used in this 
study are tabulated in Table 2.
