Geomorphic Processes

Mountain headwater streams are still somewhat on the boundary of interest regarding possible human impact on their morphology or geomorphic processes, which may be caused by our perception of mountains as islands of relatively preserved natural conditions. This paper summarizes the past and present human pressure on the headwater streams that drain the highest mountain ranges of the Outer Western Carpathians in Czechia. Anthropogenic pressure began in this region in the 16th century during a colonization of the mountains and continued by timber harvesting, timber floating, and construction of torrent control works until present. Each of these interventions produced a morphological response of the channels in relation to altered sediment or water fluxes at the whole catchment scale or within longitudinal stream profiles. Because it is highly unlikely to reach pre-settlement conditions of the channels, the management effort should be concentrated to achieve realistic restoration targets under the present socioeconomic circumstances by taking into consideration the morphodynamical specifics of mountain headwater streams.

Filling Phase

The composition of the diet of Macquarie perch changed markedly during the various stages of rising and falling water-level during the initial filling phase of Lake Dartmouth, an impoundment formed by the construction of Dartmouth Dam on the Mitta Mitta River in north-eastern Victoria. Macquarie perch fed on typical river-dwelling organisms from inflowing rivers, on terrestrial organisms that became displaced as the water-level rose, and on typical still-water or sluggish-water organisms, which were extremely abundant in the newly created lake. The relative proportions of several of these food types in the diet varied depending on whether the water-level was rising or falling. Macquarie perch appear to have adapted well to the changing food supply in the lake, and have included in their diet several food types that they would not normally have encountered in their natural riverine habitat.
