The Effect of Climate Change on Rainfall Trends and Flooding Risk in the West of Scotland
Climate Change Rainfall Trends Flooding Risk
2009/10/23
Evidence is presented of a general increase in river flows in four catchments in
the West of Scotland in the last 30 years. The increase has been significantly
higher than the increase in rainfall o...
A comparison of methods for estimating soil characteristics in regional acidification models; an application of the MAGIC model to Scotland
Acid Neutralising Capacity soil depth soil physico-chemical
2009/6/5
The results from an application of MAGIC (Model of Acidification of Groundwater In Catchments) to 733 Scottish catchments are presented. The availability of representative, good quality soil data is f...
Hydrogeochemsitry of montane springs and their influence on streams in the Cairngorm mountains, Scotland
montane springs Scotland Cairngorm mountains
2009/5/26
Springs are important groundwater discharge points on the high altitude (>800m) plateaux of the Cairngorm mountains, Scotland and form important wetland habitats within what is often a dry, sub-arctic...
Faecal sterols as indicators of sewage contamination in estuarine sediments of the Tay Estuary, Scotland：an extended baseline survey
Faecal sterols sewage contamination estuarine sediments
2009/5/18
Sterol ratios are used to identify sources, occurrence and partitioning of faecal matter in sediments of the Tay Estuary, Scotland. The 5β/(5α+5β) ratio is used to discriminate between sewage and biog...
Acid episodes in the Allt a'Mharcaidh, Scotland：an investigation based on sub-hourly monitoring data and climatic patterns
North Atlantic Oscillation climatic patterns sub-hourly resolution
2009/5/6
Stream waters in the Allt a'Mharcaidh catchment (Cairngorms, Scotland) have been monitored for flow, conductivity and pH at sub-hourly resolution; and for a range of chemical, biological and physical ...
Evaporation from Scots pine (Pinus sylvestris) following natural re-colonisation of the Cairngorm mountains, Scotland
Atul H. Haria David J. Price
2009/3/24
Recently, changing land-use practices in the uplands of Scotland have resulted in increased re-colonisation of wet heath moorland by natural Scots pine (Pinus sylvestris) woodland. The simple semi-emp...
Theory and practice of hydrostatic lysimeters for direct measurement of net seepage in a patterned mire in north Scotland
acrotelm blanket mire ecohydrology
2009/3/24
A novel design of lysimeter for use in mires (peatlands) with shallow water tables is described. It employs an hydraulic mechanism for the automatic equilibration of soil moisture distribution between...
Controls on nitrate leaching from upland moorland catchments are not yet fully understood and yet, despite agreements on emission reductions, increased surface water nitrate concentrations may affect ...
Land use influences on acidification and recovery of freshwaters in Galloway, south-west Scotland
acidification afforestation deposition
2009/3/24
The long term response of surface waters to changes in sulphur deposition and afforestation is investigated for three upland river systems in the Galloway region of south-west Scotland. From 1984-1999...
Seasonality, water quality trends and biological responses in four streams in the Cairngorm Mountains, Scotland
hydrochemistry hydrology trends
2009/3/24
The chemical composition and invertebrate communities found in four streams in the Cairngorms, Scotland, were monitored between 1985-1997. Stream waters were mildly acidic (mean pH ca. 6.5), with low ...
Recovery from acidification of lochs in Galloway, south-west Scotland, UK: 1979-1998
acidification recovery Galloway
2009/3/24
The Galloway region of south-west Scotland has historically been subject to long-term deposition of acidic precipitation which has resulted in acidification of soils and surface waters and subsequent ...
Modelling nitrogen dynamics and distributions in the River Tweed, Scotland: an application of the INCA model
Nitrate nitrogen modelling Tweed INCA
2009/3/17
The INCA (Integrated Nitrogen in Catchments) model was applied to the River Tweed in the Scottish Borders, a large-scale (4400km2), spatially heterogeneous catchment, draining a wide range of agricult...
Processing of pine (Pinus sylvestris) and birch (Betula pubescens) leaf material in a small river system in the northern Cairngorms, Scotland
leaf processing pine needles shredders Pinus sylvestris Betula pubescens Scotland
2009/3/5
Processing rates, and macroinvertebrate colonisation, of pine needles and birch leaves were studied at eight sites on the river Nethy, a small river system in the Cairngorm region of north-eastern Sco...
An analysis of the long-term variation in stream water quality for three upland catchments at Loch Dee (Galloway, S.W. Scotland) under contrasting land management
trend analysis land management sea-salts S.W. Scotland
2009/3/5
A long term record of water chemistry, consisting of twenty years of weekly spot samples, from three sub-catchments draining into a loch and the loch outflow in Galloway, S.W. Scotland have been analy...
