| Zusammenfassung |
| River restoration has become a common measure to repair
anthropogenically-induced alteration of fluvial ecosystems. The inherent
complexity of ecohydrologic systems leads to limitations in understanding the
response of such systems to restoration over time. Therefore, a significant effort has been dedicated in the recent years
worldwide to document the efficiency of restoration actions and to produce
new effective guidelines that may help overcoming existing deficiencies. At
the same time little attention was paid to illustrate the reasons and the use
of certain monitoring and experimental techniques in spite of others, or in
relation to the specific ecohydrologic process being investigated. The
purpose of this paper is to enrich efforts in this direction by presenting
the framework of experimental activities and the related experimental setup
that we designed and installed in order to accomplish some of the research
tasks of the multidisciplinary scientific project RECORD (Restored Corridor
Dynamics). Therein, we studied the morphodynamic evolution of the restored
reach of the River Thur near Niederneunforn (Switzerland), also in relation
to the role of pioneer vegetation roots in stabilizing the alluvial sediment.
In this work we describe the methodology chosen for monitoring the river
morphodynamics, the dynamics of riparian and of in-bed vegetation and their
mutual interactions, as well as the need of complementing such observations
with experiments and with the hydraulic modeling of the site. We also discuss
how the designed installation and the experiments integrate with the needs of
other research groups within the project, in particular providing data for a
number of investigations thereby including surface water and groundwater
interactions, soil moisture and vegetation dynamics. |
