✦ Synopsis

Investigations of fifteen sections of seven Austrian epipotamal (barbel region) streams between 1981 and 1984 demonstrate the impact of instream river bed structures on fish communities . Reduced spatial heterogeneity due to river straightening resulted in decreasing species number, diversity, stock density and biomass . Reincreased variability of the river bed in the frame of a subsequent restructuring project improved all community-specific values significantly within a 3-year investigation period (1988)(1989)(1990) . Besides the regained habitat variability in form of riffle pool sequences and other instream structures, the newly created riparian zones obviously provided important niches, e .g . as refuge areas during flooding and as nursery grounds for fish fry . The positive effects of the recreated land/water ecotone are discussed with respect to river restoration projects .

## Abstract Water quality was determined on the Mahakam River floodplain from 1980 to 1987. Five water‐body types were distinguished, i.e. slow‐flowing and faster‐flowing rivers, lakes, small waterbodies and swamps. Water quality in large rivers was stable in the short but not the long term. In all

In July 1996, a survey of the macroinvertebrate fauna of the River Thames was undertaken in the vicinity of Didcot A Power Station, which is located on the right (south) bank of the river. The aim was to determine whether short-range biological effects could be detected due to abstraction and discha
