Water Resources Research: River Restoration Katie Halvorson
2
“Many river restoration projects are conducted with minimal scientific context.” Main point:
3
“assisting the establishment of improved hydrologic, geomorphic, and ecological processes in a degraded watershed system and replacing lost, damaged, or compromised elements of the natural system” Their definition of river restoration:
4
Restoration of PROCESS is more likely to succeed instead of a fixed end point. Only addresses symptoms Needs to be looked at in the context of an entire watershed. The two ideas:
5
Lack of scientific knowledge of watershed-scale projects Dynamics of watershed Structures that are poorly suited to large-scale management Lack of political support Limitations:
6
1.Transferring knowledge from one study to another 2.Restoration actions are applied to too small of scales 3.Integrating disciplinary knowledge into interdisciplinary understanding. Three common factors limiting river function:
7
Bank stabilization Fencing Engineering fish habitat Commercial uses Esthetic interests Recreational uses Quick fixes = not good
8
>38,000 restoration projects in US Most commonly stated goals: Enhance water quality Manage riparian zones Improve in-stream habitat Fish passage Bank stabilization No complete watershed idea Study
9
“many restoration activities have failed”
10
Continually develop theoretical framework that allows achieving restoration objectives. Develop studies examining relative contributions of processes operating at different time and space scales. Enhance the science and use of restoration monitoring. Link science, practitioners, and stakeholders. Strategy for achieving vision
