  1. 1. Näringsförluster från sju jordbruksområden nära Mälaren

    University essay from SLU/Dept. of Soil and Environment

    Author : Sally Karlsson Bondesson; [2024]
    Keywords : avrinningsområde; belastning; fosfor; kväve; S-HYPE; retention; typområden på jordbruksmark; vattenflöde; VISS; våtmark;

    Abstract : Ett av Sveriges miljömål är ”ingen övergödning” vilket innebär att gödande ämnen inte ska ha negativ inverkan på människor, biologisk mångfald eller mark-och vattenanvändning (Naturvårds-verket 2023). Näringsämnena fosfor och kväve och förlusten av dessa från framför allt jordbruksmark är en av orsakerna till övergödning i sjöar, hav och vattendrag. READ MORE

  3. 2. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Daniel Elfström; Max Stefansson; [2021]
    Keywords : cloudbursts; cloudburst mapping; spatial rain variation; pluvial flooding; hydraulic response; Swedish precipitation radar data; idealized urban catchment; hydrodynamic modeling; skyfall; skyfallskartering; gaussisk regnfördelning; spatial regnvariation; pluvial översvämning; hydraulisk respons; svensk nederbördsradardata; idealiserat urbant avrinningsområde; hydrodynamisk modellering;

    Abstract : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. READ MORE

  4. 3. A Lead (Pb) Mass-Balance Budget for a Dry Periglacial Catchment in West Greenland : Discussing the fate of pollutant Pb

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Andreas Nylund; [2020]
    Keywords : Lead mass-balance budget; Dry periglacial landscape; Whole catchment; Pollution; Climate change;

    Abstract : Lead (Pb), occurs both naturally and as a pollutant in Arctic landscape systems. The ongoing climate change, especially pronounced in the Arctic, changes the premises for Pb transport and mobility. READ MORE

  5. 4. Forest drainage effects on tree growth in Northern Sweden : developing guidelines for ditch network maintenance

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Hanna Glöd; [2018]
    Keywords : ditch cleaning; ditch network maintenance; drainage effect; forest drainage; indicators; dikningseffekt; dikesrensning; dikesunderhåll; indikatorer; skogsdikning;

    Abstract : At present, there are no clear guidelines for when and where ditch network maintenance (DNM) should be performed in Sweden. Recently there have been attempts to create tools that indicate the need for DNM, one of these tools is the Ditch Flow Tracker (DFT). READ MORE

  6. 5. Landscape factors related to performance of in-situ sensors for prediction of total phosphorus : a statistical analysis of data from 194 streams in Sweden

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Cham Hoang; [2017]
    Keywords : surface water monitoring; surrogate parameters; total Phosphorous; turbidity; catchment; land-use; soil type;

    Abstract : Accurate monitoring data of phosphorus concentrations in the water will benefit the evaluation of measures taken to reduce the problems of eutrophication. Today, the quantification of phosphorus loads from diffuse sources involves large uncertainties. READ MORE
