Detection of Changes in the River Bed and Identification of Boundary Changes Using Topographic Data from Different Epochs

Abstract

The river Bosna is the right tributary of the Sava River, which has its source at the foot of Mount Igmannear Sarajevo. The entire river basin of Bosna is located in Bosnia and Herzegovina and represents the most densely populated place in the Federation of Bosnia and Herzegovina. The floods of the Bosna River occur from time to time. Some of them were disastrous, as they were in 2014. The problem of flooding in recent years is the focus of numerous research around Europe and the world due to numerous floods that have resulted in massive destruction and human casualties. The increased frequency of extreme natural disasters is associated with the climate change, which is getting more extreme year after year. When it comes to river basins, they mostly do not know the political boundaries, and problems related to the definition of borders (state, entity, cantonal, municipal, cadastre) are always in trend, especially when it comes to the lives of people who live or own real estate near the river. This article identifies and analyzes the changes occurring within the administrative boundaries defined by the middle of the river trough. The time-flow changes (1959, 1968, 1974/1977, 2008 and 2012) of the Bosna river basin (in the section of the lower flow) were analyzed, and therefore the change of the municipal and cadastral border. As a result of the change in the flow of the river Bosna, the loss/gain of arable land is evident. It also provided an overview of procedures and legislation in Bosnia and Herzegovina dealing with the establishment of administrative boundaries, procedures for their renewal/change, and the boundaries of water resources that are directly related to monitoring the flow of watercourses.
