The e-book concentrates on hydrological and geomorphological tactics in mountain rivers with nearly all of the contributions concentrating on the Alps.
Methods and result of learn in strong load delivery and river mattress dynamics are awarded through foreign authors. The authors come from earth technological know-how and engineering associations and either sensible and theoretical elements of mountain river study are addressed.
The booklet is a necessary consultant and resource of data on difficulties of environmental making plans and defense, river administration and danger assessment.

Discharge regulation is controlled by an inductive flowmeter. Both are connected to the computer. At the model outlet the water pours down into a basement reservoir where i t is pumped back into the elevated supply reservoir. The water level at the model outlet is controlled by a nearby gauge and may be adjusted by an overflow plate.
