Subject:
adsorption; biogeochemistry; color; dissolved organic carbon; hydrochemistry; mineral soils; pH; peat; rivers; runoff; silicon; soil horizons; statistical analysis; subwatersheds; sulfur; temporal variation; England
Abstract:
... This study compares the spatial and temporal variability of water colour for fifteen sub-catchments of the River Nidd, northeast England, in 1986 and 2006/2007. Between 1986 and 2006/2007, mean annual water colour increased in all the sub-catchments. However, there was considerable variation in the increase, which ranged from 22 to 155%. Statistical analysis revealed that the sub-catchments could ...

2. Effects of managed burning upon dissolved organic carbon (DOC) in soil water and runoff water following a managed burn of a UK blanket bog

Journal of hydrology 2009 v.367 no.1-2 pp. 41-51
ISSN:

Subject:
peat; water quality; highlands; watersheds; bogs; soil water; grazing intensity; dissolved organic carbon; color; prescribed burning; hydrochemistry; runoff; grasslands; England
Abstract:
... The burning of heather and grass to maintain a mosaic of different aged vegetation stands is a widespread management practice in the uplands of the UK. However, there is concern that burning also releases dissolved organic carbon (DOC) into drinking water supplies. This study was based on a long term experiment examining different rotational burning cycles and grazing intensities on upland vegetat ...

3. Short-term impact of peat drain-blocking on water colour, dissolved organic carbon concentration, and water table depth

Journal of hydrology 2007 v.337 no.3-4 pp. 315-325

Subject:
peat; drainage water; water pollution; dissolved organic carbon; groundwater; color; hydrochemistry; water table; drainage; England
Abstract:
... Water discolouration is a major management problem for UK water companies as a proportion of the supply relies on runoff from peat-covered catchments. Many peats have been drained using surface ditches but this has been shown to lead to more severe water discolouration. Drain-blocking is now actively encouraged in UK peatlands to promote peatland habitats and water companies are considering fundin ...

Journal of hydrology 2013 v.479 pp. 169-179

Subject:
carbon sequestration; color; dissolved organic carbon; drainage; drainage channels; highlands; monitoring; peat; peatlands; preferential flow; streams; surface water; watersheds; England
Abstract:
... Extensive drainage of UK peatlands has been associated with dehydration of the peat, an increase in water colour and a loss of carbon storage. It has been considered that the blocking of these drainage channels represents a means of peat restoration and a way of reducing dissolved organic carbon (DOC) losses to surface waters. This study aimed to assess the effectiveness of drain blocking at both ...
