Floods are among the most damaging of natural disasters, and flood events are expected to increase in magnitude and frequency with the effects of climate change and changes in land use. As a consequence, much focus has been placed on the engineering of structural flood mitigation measures in rivers. Traditional flood protection measures, such as levees and dredging of the river channel, threaten floodplains and river ecosystems, but during the last decade, sustainable reconciliation of freshwater ecosystems has increased. However, we still find many areas where these traditional measures are proposed, and it is challenging to find tools for evaluation of different measures and quantification of the possible impacts. In this paper, we focus on the river Lærdal in Norway to (i) present the dilemma between traditional flood measures and maintaining river ecosystems and (ii) quantify the efficiency and impact of different solutions based on 2D hydraulic models, remote sensing data, economics, and landscape metrics. Our results show that flood measures may be in serious conflict with environmental protection and legislation to preserve biodiversity and key nature types.

Instream Wood

The recognition of instream wood as a key element of river ecosystems and a driver of fluvial processes is now well established, but it did not start until the second half of the twentieth century. A landmark reference work which led to the development of concepts and methods which are still employed in instream wood studies today was the work by Frederick J. Swanson and his papers published between 1976 and 1979. In this article we revisit these papers, highlighting the pioneering observations about the effects of instream wood on fluvial morphology, the description of the instream wood sources and recruitment processes and the discussion about management of wood in rivers. The instream wood research has grown dramatically since the late 1970s, however many knowledge gaps remain; this short historical review illustrates the importance of continuing and developing those research lines into the future.
