Headwater Influences on Downstream Water Quality
We investigated the influence of riparian and whole watershed land use as a function of stream size on surface water chemistry and assessed regional variation in these relationships. Sixty-eight watersheds in four level III U.S. EPA ecoregions in eastern Kansas were selected as study sites. Riparian land cover and watershed land use were quantified for the entire watershed, and by Strahler orde...
متن کاملThe Role of Headwater Streams in Downstream Water Quality1
Knowledge of headwater influences on the water-quality and flow conditions of downstream waters is essential to water-resource management at all governmental levels; this includes recent court decisions on the jurisdiction of the Federal Clean Water Act (CWA) over upland areas that contribute to larger downstream water bodies. We review current watershed research and use a water-quality model t...
متن کاملInfluence of Headwater Streams on Downstream Reaches in Forested Areas
The source areas of headwater streams typically compose 60% to 80% of a catchment. This, plus the typical increase in precipitation with elevation, means that headwater streams generate most of the streamflow in downstream areas. Headwater streams also provide other important constituents to downstream reaches, including coarse and fine sediment, large woody debris, coarse and fine organic matt...
متن کاملWater quality assessment of Vasileva Lake based on diatoms influences by tourism, fishing and recreation
Surface waters in recent years are under the great influence of industrial and anthropogenic factors. Vasileva Lake has been impacted by anthropogenic factors. It has been exploited by people for recreation, vacation and fishing, which exposed Vasileva Lake to occurrence of pollution. Purpose of this work was to evaluate the status of water quality in this artificial lake, using algae-diatoms a...
متن کاملHuman influences on water quality in Great Lakes coastal wetlands.
A better understanding of relationships between human activities and water chemistry is needed to identify and manage sources of anthropogenic stress in Great Lakes coastal wetlands. The objective of the study described in this article was to characterize relationships between water chemistry and multiple classes of human activity (agriculture, population and development, point source pollution...
