The Water Quality of Streams Draining a Plantation Forest on Gley Soils: the Nant Tanllwyth, Plynlimon Mid-wales 485 the Water Quality of Streams Draining a Plantation Forest on Gley Soils: the Nant Tanllwyth, Plynlimon Mid-wales
The water quality of the Nant Tanllwyth stream in the Plynlimon region of mid-Wales is related to the key hydrobiogeological controls and the effects of conifer harvesting based on an analysis of rain, cloud, stream and groundwater measurements. The results show the normal patterns of stream water quality response to hydrology. Thus, there is a high damping of atmospheric inputs due to storage ...
متن کاملChemistry of streams draining grassland and forest catchments at Plynlimon, mid-Wales
The chemistry of streamwater, bulk precipitation, throughfall and soil waters has been studied for three years in two plantation forest and two moorland catchments in midWales. Na and CI are the major ions in streamwater reflecting the maritime influence on atmospheric inputs. In all streams, baseflow is characterised by high pH waters enriched in Ca, Mg, Si and HC03. Differences in baseflow ch...
متن کاملInfluence of Maximum Water Temperature on Occurrence of Lahontan Cutthroat Trout within Streams
—We measured water temperature at 87 sites in six streams in two different years (1998 and 1999) to test for association with the occurrence of Lahontan cutthroat trout Oncorhynchus clarki henshawi. Because laboratory studies suggest that Lahontan cutthroat trout begin to show signs of acute stress at warm (.228C) temperatures, we focused on the maximum daily temperature. The maximum daily temp...
متن کاملexperimental investigation of atomization of water jets in air streams
atomization is a process by which a volume of liquid is converted spray. this process includes the breakup of the liquid jet or the liquid sheet exiting the injector. this paper has experimentally investigated the models and mechanisms for the breakup of the liquid jet and the liquid sheet formed by the jets impingement in a still environment and in an environment with counter flow, coflow, and...
متن کاملLong-term changes in the water quality of rainfall, cloud water and stream water for moorland, forested and clear-felled catchments at Plynlimon, mid-Wales
Long term changes in the water quality of rainfall, cloud water and stream waters draining acidic and acid sensitive moorland and forested catchments at Plynlimon, mid-Wales, are examined for the period 1983 to 2001. Atmospheric inputs of chloride and sulphate are influenced by the relative inputs of clean maritime and polluted land based air masses. There is no systematic increase or decrease ...
