Geographical changes of the Bosut River Basin

In the east part of the Republic of Croatia there is an agricultural area with a long tradition. This area is part of the Sava valley which natural features were created long time ago. But, in the last few hundred years these natural features were significantly modified by human activities. This area has continental climate and relatively little rainfall. Hydrographic backbone of the newly formed valley is the Bosut River with its few major tributaries (Biđ River and Spačva River). Biđ-Bosut basin extends to the field of three Croatian counties, and it is in the backbone of life for a number of their municipalities. The lower part of the basin is located in the Republic of Serbia and is the life part of the local population. Biđ-Bosut basin ones were swampy and forested lowland area on the civilization crossroads. Then it becomes mainly an agricultural area, been developed within a united state on the basis of socialistic planning and state ownership. Today this area is marked by damage and neglect of previously built hydropower system. Also, valley is marked with the adaptation and extension of the divided basin which is situated on the border of the three neighbor states with different hydrotechnical organization. This paper describes the climate, hydrological and morphological characteristics of the Biđ-Bosut basin and its complex hydrotechnical system. The agricultural production in this area is aided by developed amelioration drainage, but runoff in the basin is very specifically. River beds are regulated, slopes of them are very small, and many local population do not know the name of the individual streams and direction of its water flows. Paper also points out the specific problem in this region in the period of small and high water, and the possible challenges due to climate changes and adaptations for survival. The local challenges are also social relations where benefits and adversity can contribute to the unification or misunderstanding between neighbor countries.
