Swedish Bypassed River Reaches Register SBRRR
type: Dataset
description: The Swedish Bypassed River Reaches Register (SBRRR) is a dataset containing descriptive information about 968 unique bypassed river reaches located at Swedish diversion hydropower stations. These are formerly natural river reaches currently more or less devoid of water due to hydropower operations. The dataset contains information about the intrinsic hydrogeographical characteristics (i.e. prior to hydropower development) of these reaches such as channel slope, altitude, natural flow regime, catchment geology and soil characteristics, etc. The dataset also contains information about the size of the bypassed reaches (length, area), current management practices in terms of allocation of water as minimum discharge and any other implemented restoration measures (e.g. fishways, habitat enhancement) and additional pressures on the aquatic ecosystem of the bypassed reach (i.e. anthropogenic land use in the catchment area). The datafile itself consists of 57 columns and 968 rows.

hydroelectric energy
type: DefinedTerm
description: The free renewable source of energy provided by falling water that drives the turbines. Hydropower is the most important of the regenerable energy sources because of its highest efficiency at the energy conversion. There are two types of hydroelectric power plants: a) run-of-river power plants for the use of affluent water; b) storage power plants (power stations with reservoir) where the influx can be regulated with the help of a reservoir. Mostly greater differences in altitudes are being used, like mountain creeks. Power stations with reservoirs are generally marked by barrages with earth fill dam or concrete dams. Though hydropower generally can be called environmentally acceptable, there exist also some problems: a) change of groundwater level and fill up of the river bed with rubble. b) Risk of dam breaks. c) Great demand for land space for the reservoir. d) Diminution, but partly also increase of value of recreation areas. As the hydropowers of the world are limited, the world energy demand however is rising, finally the share of hydropower will decrease.

habitat destruction
type: DefinedTerm
description: Destruction of wildlife habitats by increasing pressure for land by fast-growing human populations, pollution and over-exploitation. Whole species or populations of plants and animals have disappeared causing a loss of genetic resource that is not only regrettable from an aesthetic or philosophical point of view but also threatens man's food supply. Habitat loss takes several forms: outright loss of areas used by wild species; degradation, for example, from vegetation removal and erosion, which deprive native species of food, shelter, and breeding areas; and fragmentation, when native species are squeezed onto small patches of undisturbed land surrounded by areas cleared for agriculture and other purposes.
