   Sammanfattning : The general objective of this thesis is to contribute to the knowledge of the transport of sediments and pollutants from catchments to downstream water recipient systems and their accumulation in these systems, such as lakes and lake sediments. One part of the thesis studies the importance of drainage reach morphology and water flow for the phosphorous (P) transport and retention in the reaches, and the main controlling processes of the P retention in the reach sediments.

3. 2. Solute Transport Across Scales : Time Series Analyses of Water Quality Responses to Quantify Retention and Attenuation Mechanisms in Watersheds

   Författare :Joakim Riml; Anders Wörman; Aaron I. Packman; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solute transport modeling; Transient storage; Tracer test; Central temporal moments; Spectral analysis; Parameterization;

   Sammanfattning : The intra-continental movement of waterborne contaminants is governed by the distribution of solute load in the landscape along with the characteristics and distribution of the hydrological pathways that transport the solutes. An understanding of the processes affecting the transport and fate of the contaminants is crucial for assessments of solute concentrations and their environmental effect on downstream recipients.
