Runoff production in blanket peat covered catchments
[1] Blanket peat catchments exhibit flashy regimes, but little is known about the exact nature of runoff production processes within these catchments. Catchment, hillslope, and plot-scale monitoring results are presented from the blanket peats of the northern Pennines, United Kingdom. Catchment efficiency for three study catchments with areas of 11.4 km, 0.83 km, and 0.44 km were 72%, 77%, and ...
متن کاملInfiltration, runoff and sediment production in blanket peat catchments: implications of field rainfall simulation experiments
Blanket peat covers the headwaters of many major European rivers. Runoff production in upland blanket peat catchments is flashy with large flood peaks and short lag times; there is minimal baseflow. Little is known about the exact processes of infiltration and runoff generation within these upland headwaters. This paper presents results from a set of rainfall simulation experiments performed on...
متن کاملHydraulic conductivity in upland blanket peat: measurement and variability
A key parameter used in wetland hydrological and landform development models is hydraulic conductivity. Head recovery tests are often used to measure hydraulic conductivity, but the calculation techniques are usually confined to rigid soil theory. This is despite reports demonstrating the misapplication of rigid soil theory to non-rigid soils such as peats. Although values of hydraulic conducti...
متن کاملControls of soil pipe frequency in upland blanket peat
[1] Soil pipes were surveyed in 160 British blanket peat catchments using consistent application of ground-penetrating radar. Soil pipes were found in all catchments. The mean frequency of piping was 69 per kilometer of surveyed transect. Land management (moorland gripping) appears to exert the most important control on hillslope pipe frequency in blanket peats. Management practice in peatlands...
متن کاملLinksbetweenmethane£uxand transcriptional activitiesof methanogensandmethaneoxidizers ina blanket peat bog
The relationship between biogeochemical process rates and microbial functional activity was investigated by analysis of the transcriptional dynamics of the key functional genes for methanogenesis (methyl coenzyme M reductase; mcrA) and methane oxidation (particulate methane monooxygenase; pmoA) and in situ methane flux at two peat soil field sites with contrasting net methane-emitting and -oxid...
