Article
Most of the rivers in the Polish Carpathians are regulated over long sections by a sequence of grade control structures (GCSs), reducing the channel bed gradient. Their impact on changes in river morphodynamics is still little known. It is usually believed that they interrupt the continuity of the river and thus deteriorate its ecological quality....
Article
Grade control structures (GCSs) are one of the most often used hydraulic structures in a river regulation in mountain catchments. The purpose of their use is to reduce the river bed gradient and prevent downcutting. The aim of this study is to evaluate the influence of GCS on changes in river bed morphology. The study was conducted in a downstream...

Grade control structures (GCSs) serve as some of the most frequently used forms of river channel regulation in the Polish Carpathians. The main purpose of such structures is to reduce the gradient of the channel and strike a balance between erosion and deposition. Despite the widespread use of GCSs, not much is known about their functioning over th...

Channel response to dam removal is still poorly understood, as there is a lack of monitoring data. A small dam in the gravel bed Krzczonówka Stream was lowered in 2014 as the first in the Polish Carpathians. The paper describes the direction and magnitude of channel changes after the check dam lowering against the backdrop of slow changes in the ri...

Natural riffles are formed as a result of fluvial processes in the stream channel, water flow, and sediment movement. In recent years, artificial riffles have also been constructed in order to improve the water flow and sediment transport as well as to initiate the processes that lead to the restoration of natural riffle-pool sequences. In river en...

The research was conducted on the Krzczonówka River channel, one of the gravel-bedded, regulated mountain river in Polish Carpathians. The main morphological and ecological problem of the river was lack of sediment and channel downcutting. The area is currently associated with an on-going project called "the Upper Raba River Spawning Grounds". Lowe...

Abstrakt. Górne, zalesione czêoeci zlewni górskich cechuj¹ siê du¿¹ retencyjnooeci¹, odp³ywem podziemnym oraz niezorganizowanym i epizodycznym sp³ywem po-wierzchniowym, a ich rozwój jest zwi¹zany g³ównie ze zdarzeniami ekstremalnymi. Jednym z g³ównych celów analiz by³o okreoelenie kierunku ods³aniania korzeni, które pozwala na odró¿nienie procesów...
Article
The purpose of this paper is to explain the influence of river training on channel changes in mountain rivers. Also considered are the causes of failure of different training schemes. The research was conducted on the regulated Mszanka and Porębianka Rivers, belonging to the Raba River drainage basin in the Polish Flysh Carpathian Mountains. Channe...
Article
The article demonstrates the present state of knowledge about the reasons of Carpathian channel changes and channel response to various interferences. A range of modern alternative solutions in the matter of mountain fluvial system management is also presented.
