  1. 26. Riparian buffer zones in agricultural landscapes : Their status today and their future as an ecological tool in Sweden

    University essay from Karlstads universitet

    Author : Mikaela Ignatiou Hadjicharalambous; [2021]
    Keywords : Riparian buffer zones; agriculture lanscapes; ecological tool; streams; kantzoner; lantbrukslandskap; ekologisk vertyg; vattendrag;

    Abstract : The application of intensive farming and cultivation practices, resulting in large-scale modification of the hydrology of streams and rivers and of the natural vegetation, has increased the need to find ways to mitigate the negative impact of this habitat degradation. Suitable design and creation of riparian buffer zones in agriculture areas, is by many considered the best remedial measure. READ MORE

  3. 27. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maximilian Rafael Huber; [2021]
    Keywords : physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Abstract : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. READ MORE

  4. 28. Drivers of topsoil saturated hydraulic conductivity in three contrasting landscapes in Kenya

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

    Author : David Falk; [2021]
    Keywords : Infiltrability; mixed effects model; Kenya; land degradation; restoration; trees;

    Abstract : Markförsämring i tropiska regioner kan ha förödande konsekvenser för vattentillgänglighet. Vattenkvalité och kvantitet är oerhört viktiga för lokalbefolkningar och är grundförutsättningar för socioekonomisk utveckling då stora delar av befolkningen i många tropiska länder är direkt beroende av jordbruk och boskapshållning för sin inkomst.

  5. 29. Water quality and organic matter linkages in waters draining arable fields

    University essay from SLU/Dept. of Soil and Environment

    Author : Adam Eriksson; [2021]
    Keywords : Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

    Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

  6. 30. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
    Keywords : HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

    Abstract : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.
