River restoration: seeking ecological standards. Editor’s introduction
1. In the face of continuing anthropogenic stressors to freshwater systems worldwide , the natural resilience and resistance of the freshwater ecosystems that enables them to cope with or recover rapidly from certain levels of perturbation is under significant threat. In many systems, the changes brought about through human activities have significantly altered the physical habitat and ecologic...
متن کاملMesoHABSIM: A concept for application of instream flow models in river restoration planning
This paper describes the methodological concept for application of physical habitat models to restoration planning at a whole river scale. The design proposed here builds upon the Instream Flow Incremental Methodology but is focused at the need for managing large-scale habitats and river systems. It modifies the data acquisition technique and analytical resolution of standard approaches, changi...
متن کاملInstream Flow Science for Sustainable River Management
Concerns for water resources have inspired research developments to determine the ecological effects of water withdrawals from rivers and flow regulation below dams, and to advance tools for determining the flows required to sustain healthy riverine ecosystems. This paper reviews the advances of this environmental flows science over the past 30 years since the introduction of the Instream Flow ...
متن کاملSocio-ecological complexity and the restoration of river ecosystems
Understanding socio-ecological characteristics associated with rivers and their catchments, and using that understanding to effectively manage and restore river ecosystems, is an increasingly complex challenge. While great strides have been made in the last half century in understanding rivers as ecological systems, human exploitation of river water and riparian zones have frustrated river mana...
