The determination and modelling of the territory is common scientific instrument for presentation of the state of the nature and human systems. The present research is based on the morphological and hydrological peculiarities in the river catchment. It observed of the Danube coastal zone in Bulgaria sector of the river. The differentiation and determination of the coastal area is key element in the process of the management of the territory and development of the regions. The general results of the research are re...

This study aimed to reveal the dependence of the spatial distribution of heavy metals in soil on the morphography of the Lower Danube floodplain in the Ostrovska Lowland in Bulgaria. The field campaign was conducted in 2017, and the concentration of Zn, Ni, Pb and Cr were measured in the fine fraction (<0.063 mm) of 10 soil samples using X-ray fluorescence analysis. The average content of Cr in the topsoil (0-20 cm) was 127 mg/kg ranging between 98 – 171 mg/kg. It was followed by Zn – 81 mg/kg (60 – 128 mg/kg), Ni...
