Influence of Bedrock Geology on Water Chemistry of Slope Wetlands and Headwater Streams in the Southern Rocky Mountains

  title={Influence of Bedrock Geology on Water Chemistry of Slope Wetlands and Headwater Streams in the Southern Rocky Mountains},
  author={Monique LaPerriere Nelson and Charles C. Rhoades and Kathleen A. Dwire},
We characterized the water chemistry of nine slope wetlands and adjacent headwater streams in Colorado subalpine forests and compared sites in basins formed on crystalline bedrock with those formed in basins with a mixture of crystalline and sedimentary bedrock. The pH, Ca2+, Mg2+, NH4+, acid neutralizing capacity, and electrical conductivity of wetland porewater and streamwater were higher in the basins with mixed geology. Bryophyte cover was higher in lower pH, crystalline basins, and… 

Sources of variability in springwater chemistry in Fool Creek, a high‐elevation catchment of the Rocky Mountains, Colorado, USA

Springs are the point of origin for most headwater streams and are important regulators of their chemical composition. We analysed solute concentrations of water emerging from 57 springs within the 3

Hydrogeomorphic controls on soil carbon composition in two classes of subalpine wetlands

Wetlands play a vital role in terrestrial carbon (C) sequestration, but the sensitivity of their C stocks to disturbance remains uncertain, requiring enhanced understanding of the processes that

Swamps, Bogs and Other Wetlands

In geological time scales, lakes are young features on the Earth’s surface (merely decades up to many thousands of years). The existence of lakes often depends on climatic conditions that can

Temporal variation in depth to water table and hydrochemistry in three raised bogs and their laggs in coastal British Columbia, Canada

The laggs of three raised bogs in coastal British Columbia were studied in 2010–2012 to determine the temporal variation in depth to water table and hydrochemistry. The lagg is an integral, but

Quantification of runoff generation from a combined glacier and páramo catchment within an Ecological Reserve in the Ecuadorian highlands

Abstract. Hydrological processes in combined glacier and paramo catchments are vitally important to serve the water needs of communities in the surrounding areas. Previous studies have shown that the

Climate change and glacier retreat in the French Pyrénées : implications for Alpine river ecosystems

Climate change disproportionately threatens alpine river ecosystems due to the strong connections between cryosphere, hydrology and physicochemical habitat. Our general understanding of how these

Technical note: glacial influence in tropical mountain hydrosystems evidenced by the diurnal cycle in water levels

Abstract. Worldwide, the rapid shrinking of glaciers in response to ongoing climate change is modifying the glacial meltwater contribution to hydrosystems in glacierized catchments. Determining the

Physical and Chemical Monitoring of Wetland Water

The physical and chemical attributes that comprise the “water quality” of a wetland have a significant influence on the system’s biotic structure and function. Assessments of wetland water quality



Parent lithology, surface-groundwater exchange, and nitrate retention in headwater streams

We address the ecological ramifications of variation in hydrologic interaction between streams and alluvial aquifers in catchments with alluvium derived from parent materials of contrasting geologic

Hydrogeochemsitry of montane springs and their influence on streams in the Cairngorm mountains, Scotland

Abstract. 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,

Sources and chemical character of dissolved organic carbon across an alpine/subalpine ecotone, Green Lakes Valley, Colorado Front Range, United States

We investigated how the source and chemical character of aquatic dissolved organic carbon (DOC) change over the course of the runoff season (May–November, 1999) in Green Lakes Valley, a

Chemical and isotopic evaluation of water sources to the fens of South Park, Colorado

Abstract: Understanding the source of water supplying high-altitude wetlands in Colorado has gained importance as water supply demands increase in the region. The fens of South Park are rare in their

Ground water flow paths in relation to nitrogen chemistry in the near-stream zone

  • 2004
Interactions between ground water flow paths and water chemistry were studied in the riparian zone of a small headwater catchment near Toronto, Ontario. Significant variations in oxygen — 18 and

Regional and local hydrogeology of calcareous fens in the Minnesota River basin, USA

Six calcareous fens in the Minnesota River Basin, USA are in regional hydrogeologic settings with large discharges of calcareous ground water. These settings juxtapose topographically high areas of

Influence of geologic setting on slope wetland hydrodynamics

Slope wetlands exist where topographic or stratigraphic conditions allow ground water to intersect the surface, creating a zone of perennial or near-perennial moisture. The condition and resiliency

Spatial variation of wetlands and flux of dissolved organic carbon in boreal headwater streams

In order to investigate the relation between water chemistry and functional landscape elements, spatial data sets of characteristics for 68 small (0·2–1·5 km2) boreal forest catchments in western

Patterns in the Chemical Fractionation of Organic Nitrogen in Rocky Mountain Streams

The intraannual dynamics of particulate organic nitrogen (PON) and two fractions of dissolved organic nitrogen (DON) were investigated in two Rocky Mountain streams draining watersheds with low rates
