The sediments of the lower reach of the Kishon river, its harbors and estuary, sampled in 1989-1991, were highly polluted by trace metals and petroleum derived compounds released by the adjacent industries. The contamination was highest in the sediment deposition area of the Kishon fishing harbor and decreased seaward. River-borne pollution was also evident in Haifa Bay opposite the Kishon estuary. Contaminants trapped in the sediments of the lower Kishon river system can reach the marine environment through bottom transport of sediment particles and also as a result of disposal at sea of dredge spoils from the river channel and harbors. On the basis of the findings of the study, it was recommended to stop the long-time practice of dumping dredge spoils from the Kishon fishing harbor into the relatively clean Haifa Bay and to use instead an offshore deep water disposal site.

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.
