The aim of the present study is to evaluate soil organic carbon in Gulyantsi Municipality, Pleven District. The case study area of "Ulpia Eskus" Reserve was chosen for the research. The composition of soil organic substance of Arenosols + Fluvisols is distinguished by the use of a chemical analysis and the application of the Turin method. The resul...

The block fields and block streams are widespread in the Pirin Mountains. They are significant in size and are distributed on both relatively flat and sloping surfaces. Their origin is associated with frost weathering, which can subsequently be supplemented by other processes related to the destruction of the material – chemical weathering, fluvial...

The aim of the following study is to analyze physical weathering in the area of Bulgarian Antarctic Base (BAB), Livingston Island in the South Shetland Islands. Six key sites representing rock outcrops of different petrography are sampled using Schmidt Hammer (Proceq Rock Schmidt, type N). Obtained data (rebound values) is used for estimating rock...

This study aims at exploring the features of the local land cover, identifying degree of human impact on landscapes using the hemeroby index and making an overview of the current measures taken in terms of nature preservation in the Slavyanka/Orvilos and Stargach/Perivlepto mountains in Southwestern Bulgaria and Northern Greece. Since these mountai...

Collected data form meteorological station Zemen is analyzed. In the presented study authors emphasize on their application in agroclimatology and geomorphology. An attempt is made to determinate periods with certain conditions for development and activity of different environmental processes and phenomena, some of which have influence on the lands...

The presented study aims to identify and quantify organic carbon as a supporting ecosystem/landscape service of Umbrosols (UM) in Stara Planina municipalities in the eastern part of Sofia district. For this purpose descriptions and sampling were performed along the ridge of Stara Planina falling in the territory of the municipalities of Gorna Malin...

Географското изучаване разглежда резултата от взаимодействието между скали, релеф, климат, растителност, животинска и антропогенна активност във времето. В границите на административната единица почвено-оценъчното изследване анализира диференциращата роля на почвообразуващите фактори. Осъществяването на поставената цел се подкрепя с конкретно норма...
Article
The geomorphologic erosion processes can be investigated characterized and modelled using a response units approach. The purpose of this paper is to derive potential erosion areas in the catchment of Tsaparevska river (Maleshevska Mountain, Bulgaria) by applying geographic information system (GIS), digital terrain analysis and the Erosion Response...

The tumuli "Golyama Kosmatka" and "Svetitsata" located in the Valley of the Thracian Kings were subjected to geological and geomorphological study. The "Svetitsata" tumulus dates from the second half of 5 th century BC (found on Aug. 19, 2004). It is located between the small town of Shipka and the village of Krun, Kazanluk Area. A Thracian ruler w...
