WLS Report 69: Evaluation of checkdams being affected by an event similar to dimensioning value: Analysis of function and costs of affected checkdams controlling the bed load transport, on behalf of the BMLFUW
Abstract
Since the seventies, the Forest-technical Service has been using checkdams in mostly opened construction to control the bed load transport. In the meantime, various buildings were affected by larger events. During the last 3 decades the various sections and district construction managements of the Forrest-technical Service were able to gather useful experience concerning behaviour and effect of these dams hit. This expert knowledge will be lost, caused by the numerous retirements which are expected. Within the scope of this project, these experiences should be gathered nationwide. In the course of this project the effects and the behaviour of the checkdams affected, the functional connection to the related fallback system as well as the concerned events should be analysed systematically. Moreover the intention of this project is the thorough evaluation of customary checkdams controlling the bed load transport with reference to fulfilment of function, costs and the ecological influence on a river¿s fauna. Data and results of the project should be geo referenced and implemented in a GIS-compatible database. This database should be useable independently, as well as it should be integrated into the digital torrent- and avalanche cadastral as a module. On the one hand the database should provide database structures for documentation of the stress of torrent fallback systems, and on the other hand it should serve as a tool to estimate the cost maintenance.
