Due to risk of avalanche and erosion large sections of embarkments are established along both sides of Hofstadelva. Mitigation efforts included shaping of the embarkments to mimic the original stream structure, topsoil and turf transplants are used to improve natural vegetation recovery along the river.<br /> |Monitoring surveys and results=A monitoring program for fish, benthos, plant life and birds during 2016 - 2018. Natural recovery is observed for all species groups. Grazing domestic animals cause some erosion that limit establishment of forest, and soil erosion into the river might be limiting for benthos.<br /> |Lessons learn=Pre-project studies and cooperation have been important for the output. The involvemnt of experts in early phases of the projects have improved the positiv effects of mitigation. Mapping of species and ecosystem variables before the contruction is valuabel reference state for the monitoring after implementation.<br /> |Project title=Hofstadelva<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site<br /> |Name=Hofstadelva<br /> |WFD water body code=124-156-R<br /> |Heavily modified water body=No<br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> |Species=some invasive species observed<br /> |River corridor land use=Grazing, settlement<br /> }}<br /> {{Project background<br /> |Reach length directly affected=1900<br /> |Project started=2011<br /> |Total1 cost=1100<br /> |Funding sources=NVE<br /> |Investigation and design Lead organisation=NVE<br /> |Stakeholder engagement Lead organisation=NVE<br /> |Works and supervision Lead organisation=NVE<br /> |Post-project management and maintenance Lead organisation=NVE<br /> }}<br /> {{Motivations<br /> |Specific mitigation=Mitigating river environment following embankments for erosion control<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Bank stabilisation,<br /> |Planform / Channel pattern=Channelling<br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{Biological quality element table row<br /> |Element=Invertebrates: Abundance<br /> |Monitored before=Yes<br /> |Monitored after=Yes<br /> |Qualitative monitoring=No<br /> |Quantitative monitoring=Yes<br /> |Control site used=No<br /> |Result=Improvement<br /> }}<br /> {{Biological quality element table row<br /> |Element=Fish: Abundance<br /> |Monitored before=Yes<br /> |Monitored after=Yes<br /> |Qualitative monitoring=No<br /> |Quantitative monitoring=Yes<br /> |Control site used=No<br /> |Result=Improvement<br /> }}<br /> {{Biological quality element table row<br /> |Element=Fish: Age structure<br /> |Monitored before=Yes<br /> |Monitored after=Yes<br /> |Qualitative monitoring=No<br /> |Quantitative monitoring=Yes<br /> |Control site used=No<br /> |Result=Improvement<br /> }}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{Other response table row<br /> |Element=Birds<br /> |Monitored before=Yes<br /> |Monitored after=Yes<br /> |Qualitative monitoring=No<br /> |Quantitative monitoring=Yes<br /> |Control site used=No<br /> |Result=Inconclusive<br /> }}<br /> {{Other response table row<br /> |Element=river bank vegetation<br /> |Monitored before=Yes<br /> |Monitored after=Yes<br /> |Qualitative monitoring=No<br /> |Quantitative monitoring=Yes<br /> |Control site used=No<br /> |Result=Improvement<br /> }}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references<br /> |Link=https://brage.nina.no/nina-xmlui/bitstream/handle/11250/2433005/1320.pdf?sequence=4&amp;isAllowed=y<br /> |Description=Monitoring report Hofstadelva 2016<br /> }}<br /> {{Additional links and references<br /> |Link=https://www.ntnu.no/c/document_library/get_file?uuid=0ede4612-85c7-4b0e-85f7-08d7ecbd5a39&amp;groupId=10476<br /> |Description=Report before embarkment Hofstadelva 2011<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

Foto: Agder Energi<br /> |Project summary=Mandalselva is regulated for hydropower production since 1947 and this has impacted the conditions for Atlantic salmon in this river. The project &quot;Miljødesign Mandalselva&quot; used the concept of Environmental Design as described in the &quot;Handbook for environmental design in regulated salmon river (Forseth and Harby 2013) and was accompanied by thorough research efforts in order to study which measures would be suitable to improve the conditions for salmon and at the same time to take into account hydropower production. This researcj was led by the Norwegian Institute for Nature Research (NINA) and conducted in cooperation with SINTEF Energy, Norce Research and Skandinavisk Naturovervåking. It included i.a. a trade-off analysis between the production of Atlantic salmon and the production of hydropower by examining the use of several physical mitigation measures and changes in release of water. Local stakeholders and public natural resource management were involved by means of a counceling group. As a result, nine weirs in the river were removed and further habitat improving measures were put in place (e.g. installation of gravel habitat).<br /> |Monitoring surveys and results=They are expected to be published soon.<br /> |Lessons learn=to come soon...<br /> |Project title=Environmental design Mandalsvassdraget<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site<br /> |WFD water body name=Mandalselva<br /> |Heavily modified water body=No<br /> |Protected species present=Yes<br /> |Invasive species present=No<br /> |Species=Atlantic salmon (Salmo salar),<br /> |River corridor land use=Intensive agriculture (arable), Rough unimproved grassland/pasture,<br /> |Mn discharge=88<br /> }}<br /> {{Project background<br /> |Project started=01.10.2014<br /> |Works completed=2018/03/01<br /> |Total cost category=100 - 500 k€<br /> |Total1 cost=394<br /> |Funding sources=Agder Energi<br /> }}<br /> {{Motivations}}<br /> {{Measures}}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>
