| Summary: | In recent years, experts have identified that climate change
and global warming affects stream flow regime. These changes cause floods and
erosion in creeks, streams, rivers etc. Especially in semi-arid watersheds, the
structure of the land usage type is an important factor in preventing possible
disasters. The aim of this study is to determine watershed land usage type by
using hydro-morphological structure of stream and some physical water quality
parameters. To do so, hydro-morphological observations and some physical water
quality parameters were collected from 513 different points in Acıçay and
Tatlıçay watershed. For this purpose, four different Bayesian network scenarios
were considered to see the changes in the type of the land use. In this scenario,
the prediction probability of the watershed land usage type was determined with
different parameters. In conclusion, coniferous forest was predicted with the
highest probability rate of %97.
