TL;DR: In this paper, a systematic investigation of river stages and discharges was carried out for 78 stream gauges of rivers in Germany and the available times series for trends in flood stages, flood discharges, flood frequency and in stage-discharge relationships over time.

TL;DR: In this article, the principles of engineering geomorphology are developed and illustrated by examples taken from rivers that drain the French Alps and their piedmont, showing that many of these problems are directly or indirectly related to changes in the geomorphological functioning of fluvial systems.

TL;DR: Allowing the rivers to increase their sinuosity, wherever possible without an erosional threat to property and infrastructure, and preventing further in-stream gravel mining are postulated in order to arrest channel incision and reestablish the conditions for water and sediment storage on the floodplains.
Abstract: River engineers use sediment transport formulas to design regulated channels in which the river's ability to transport bedload would remain in equilibrium with the delivery of materials from upstream In gravel-bed rivers, a number of factors distort the simple relationship between particle size and hydraulic parameters at the threshold of sediment motion, inherent in the formulas This may lead to significant errors in predicting the bedload transport rates in such streams and hence to instability of their regulated channels The failure to recognize a nonstationary river regime may also result in unsuccessful channelization Rapid channel incision has followed channelization of the main rivers of the Polish Carpathians in the 20th century A case study of the Raba River shows that incision has resulted from the increase in stream power caused by channelization and the simultaneous reduction in sediment supply due to variations in basin management and a change in flood hydrographs Calculations of bedload transport in the river by the Meyer-Peter and Muller formula are shown to have resulted in unrealistic estimates, perhaps because the different degree of bed armoring in particular cross-sections was neglected It would have been possible to avoid improper channelization if the decreasing trend in sediment load of the Carpathian rivers had been recognized on the basis of geomorphological and sedimentological studies Allowing the rivers to increase their sinuosity, wherever possible without an erosional threat to property and infrastructure, and preventing further in-stream gravel mining are postulated in order to arrest channel incision and reestablish the conditions for water and sediment storage on the floodplains
