Climate conditions of the present-day relief development on Cape Verde Islands

Cape Verde Islands are an example of a local diversity of the semi-arid equatorial climate zone. The type and intensity of the present-day morphogenetic processes is determined mostly by total precipitation and vegetation cover. We can distinguish three types of relief development. In the warm, arid climate conditions throughout the year, volcanic forms are very slowly changed or preserved by the action of episodic water, limited to a material redeposition in the wadi channels and sand dune forming by the wind. In the semi-arid climate conditions, volcanic forms are transformed into denudationfl uvial relief in the rain period. It is visible mainly on the windward side of islands and at a lower altitude, where the weathering material is washed from slopes and carried away down the wadi channels to the sea after periodic torrential rains. At the same time on the leeward side, at a higher altitude and in agricultural areas only a small amount of material is transported over short distance

Polish geomorphological research in the Eastern Carpathians and the significance of Bieszczady National Park in the protection of inanimate nature

The paper describes Polish geomorphological research in the Eastern Carpathians mainly prior to World War II. Special attention is paid to the work of geomorphologists in the area of glacial relief recognition. The state of geomorphological research in the Bieszczady Mts was presented to a large extent in Volume 19 of the Roczniki Bieszczadzkie. Finally, the paper discusses the tradition of environmental protection in the Eastern Carpathians as well as significance of the Bieszczady National Park in the protection of inanimate nature

The state of the art of the studies on the Bieszczady Mts. geomorphology

The paper concerns the state of the art in research on the relief and geomorphic processes in the High and Low Bieszczady Mountains. On the basis of literature evaluation authors concluded that subsequent, detailed fieldwork is required. Furthermore additional research could supplement former opinion about development of slope and valley systems within area under considerations
