Chemical Variation and Catchment Characteristics in High Altitude Lochs in Scotland, U.K.

摘要: Previous research has established clear relationshipsbetween the chemical composition of surface waters andthe nature their contributing catchments. Theserelationships are particularly strong when broadenvironmental gradients considered. However, forfreshwaters at higher altitudes, some catchmentprocesses that mediate lessinfluential than those lower altitudes. The waterchemistry 85 upland lochs in Scotland, U.K. is examinedto assess differences along arelatively short altitude gradient. Principal componentsanalysis identifies main variationwithin dataset. A series digital datasets usedto characterise catchments according to a range ofattributes including soils and landcover. Multivariatestatistical analysis undertaken examine extentto which catchment attributes can explain variationin water chemistry systems. Theseempirical relationships may be used development ofregionalisation procedures, will allow upscaling ofknowledge from individual sites regions.
