River and stream restoration structure’s design features have been an active field of research for hydraulic engineers. Generally, these low-environmental impact structures minimize the impact on natural contexts in needless of frequent human interventions during the operation and are used for riverbank protection, river grade controlling and improving the aquatic habitat. The main objective of this paper aims to compare scour downstream of two different low-head control structures; Log-Vane and Hook vane. The analysis contains the results of laboratory experiments conducted at the PITLAB hydraulic laboratory of University of Pisa and a detailed comparison of scour hole characteristics, highlighting similitude and differences in the respective ranges of application. All tests have been done in clear water conditions using uniform sand as channel bed material.

Abstract
River and stream restoration structure’s design features have been an active field of research for hydraulic engineers. Generally, these low-environmental impact structures minimize the impact on natural contexts in needless of frequent human interventions during the operation and are used for riverbank protection, river grade controlling and improving the aquatic habitat. The main objective of this paper aims to compare scour downstream of two different low-head control structures; Log-Vane and Hook vane. The analysis contains the results of laboratory experiments conducted at the PITLAB hydraulic laboratory of University of Pisa and a detailed comparison of scour hole characteristics, highlighting similitude and differences in the respective ranges of application.
