The reconstruction of secondary channels has become an important issue in view of flood protection and nature rehabilitation of the lowland parts of the river Rhine. To maintain safety against flooding at increased river discharges, heightening the dikes is no longer opted for. Instead, measures are considered to increase the discharge capacity of the floodplains. One of these measures involves the reconstruction of secondary channels. The objective is to increase the discharge capacity and simultaneously restore floodplain nature (Silva et al., 2001; Wolfert, 2001). Since the nineties, man-made secondary channels have been constructed in the river Rhine. Monitoring shows that these channels provide suitable habitat for rheophilic macroinvertebrates and fish (Grift, 2001; Simons et al., 2001). ==References==
