23 Sediment Transport and Deposition in Mountain Rivers
In many ways, sediment transport dynamics in mountain environments differ from those of the lowlands. The high relief and the steep slopes are an obvious feature of mountain areas. The cold climate is another factor controlling runoff and erosional processes, and the distribution of vegetation is also controlled by the prevailing climate. Above the tree line, processes of erosion are more inten...
متن کاملAre mountain passes higher in the tropics? Janzen's hypothesis revisited.
Synopsis In 1967 Daniel Janzen published an influential paper titled "Why Mountain Passes Are Higher in the Tropics." Janzen derived a simple climatic-physiological model predicting that tropical mountain passes would be more effective barriers to organismal dispersal than would temperate-zone passes of equivalent altitude. This prediction derived from a recognition that the annual variation in...
متن کاملThe Magic Mountain revisited: History of the Madanapalle tB sanatorium
The sanatorium was central to tuberculosis treatment in the 19th and early 20th centuries. The long-drawn nature of treatment and the highly infectious nature of the disease made the sanatorium regimen effective and popular before antibiotics entered the scene. The sanatorium was not just a hospital, it was a social world – isolated from the rest of society it created its own definition of “com...
متن کاملThe influence of the opening width of check dams on bedload continuity of mountain rivers
The design of open check dams at mountain rivers for flood protection has an essential impact on the sediment budget of downstream river reaches. A key issue is the bedload transfer hindering and retention which can be influenced by the geometry of the openings of check dams. Contemporary design concepts provoke the retention of too much or insufficient bedload with regard to the downstream tra...
