CONTEMPORARY TRENDS AND TYPES OF CHECK DAMS FORTORRENT CONTROL IN EUROPE"" 330 $aCheck dams are a potentially effective instrument for planning of hydrological risks and soil conservation. Cross structure sequences have been used in numerous areas in the world to control flooding, recharge aquifers and stabilize mountain streams, gullies and high-gradient ephemeral channels. Nevertheless, it is little known of the effectiveness of check dams and their morphological effects. This book is an attempt to compile different based-field and laboratory research works in torrential head water areas. Bed stability variations will be investigated according to check dams types, bedrock control, bed slope, channel roughness, lateral sediment input, and highly variable sediment transport capacity. Though the main purpose of check dams is to stabilize the channel bed and diminish the boundary sheer stress reaching a minor longitudinal slope, they can reduce the volume of channel-stored material favouring local scour processes downstream and occasionally destabilize the hill slopes upstream. 410 0$aEnvironmental science, engineering and technology series. 606 $aDams 606 $aStream channelization 606 $aSoil conservation 615 0$aDams. 615 0$aStream channelization. 615 0$aSoil conservation. 676 $a627/.8 701 $aConsesa Garcia$b Carmelo$01863940 701 $aLenzi$b Mario A$g(Mario Aristide)$01863941 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910958117703321 996 $aCheck dams, morphological adjustments and erosion control in torrential streams$94470645 997 $aUNINA
