  • This paper discusses the effects of water quality on the hydrological and erosion response of non-saline, non-sodic soils during simulated rain experiments. Two soils, a well-aggregated clay-rich soil developed on marine silty clay deposits
  • and a soil developed on silt loam, were selected and subjected to a series of simulated rainstorms using demineralized water and tap water. The hydrological response (infiltration, runoff), the physical degradation (soil surface roughness change and top-soil

  • In southern African countries soil erosion and the related problems such as water quality issues or decreasing soil productivity are the main problems affecting the inhabitants of rural and urban areas. This study deals with the identification

  • Spatial variation of early season surface water chemistry in Kärkevagge, Swedish Lapland
  • This study examines the spatial variability of early season water chemistry in the arctic-alpine valley of Kärkevagge. The data demonstrate the spatially heterogeneous nature of water chemistry and the general patterns of chemical weathering
  • in the valley. Water chemistry in this valley is dominated by 2 anions, bicarbonate and sulfate. Spatial patterns of chemical constituents reflect the broad effects of local geology on surface water chemistry. In particular, they demonstrate the effects
  • that mineral species present in minor amounts have on basin-wide water chemistry.

  • The waters off northern Iceland are subjected to extreme hydrographic variability on annual to decadal timescales. In years when cold low-salinity water moves coastward and sea ice is prevalent (i.e., the late 1960s), marine productivity of surface
  • waters is low because the water column is well stratified. In the opposite oceanographic mode, warm, salty Atlantic Water dominates the shelf and vertical mixing results in high productivity. The AA. track these 2 contrasting modes by measuring
