  1. 1. Groundwater Modelling in southeast Cambodia - Facing irrigation and groundwater level changes during a pandemic

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Svea Bertolatus; [2024]
    Nyckelord :Cambodia; GMS Modflow; Groundwater modelling; irrigation; Mekong; Prey Veng; Svay Rieng; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : In the Mekong region, sustainable water resource management is a significant challenge for all countries involved. In Cambodia, where rice production is crucial for household food security and export, groundwater is increasingly used for irrigation during the dry season, leading to higher rice yields. LÄS MER

  3. 2. Estimation of Water Depth from Multispectral Drone Imagery : A suitability assessment of CNN models for bathymetry retrieval in shallow water areas

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Qianyao Shen; [2022]
    Nyckelord :Bathymetry Retrieval; Multispectral Imagery; Convolutional Neural Network CNN ; Hämtning Av Batymetri; Multispektrala Bilder; Konvolutionellt Neuralt Nätverk CNN ;

    Sammanfattning : Aedes aegypti and Aedes albopictus are the main vector species for dengue disease and zika, two arboviruses that affect a substantial fraction of the global population. These mosquitoes breed in very slow-moving or standing pools of water, so detecting and managing these potential breeding habitats is a crucial step in preventing the spread of these diseases.

  4. 3. Non-Destructive Biomass and Relative Growth Rate Estimation in Aeroponic Agriculture using Machine Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Oskar Åström; [2022]
    Nyckelord :Machine Learning; Image Analysis; Aeroponics; Hydroculture; Relative Growth Rate; Multi-variate Regression; Neural Network; ResNet; Plant Growth; Plant Physiology; Technology and Engineering;

    Sammanfattning : Optimising plant growth in a controlled climate requires good measurements of both biomass (measured in grams) and relative growth rate (measured in grams of growth per day and gram of plant). In order to do this efficiently and continuously on an individual level during plant development, this has to be done non-destructively and without frequent and labor intensive weighing of plant biomass.

  5. 4. Effects of modified river cross-section geometry on hydraulic modelling performance: the slope break method

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Feixiong Qu; [2021]
    Nyckelord :;

    Sammanfattning : Remote sensing data has been widely used for large scale hydraulic modelling in the world. One of the most common ways to collect remote sensing data is by satellite. The digital elevation data observed from space is publicly accessible and covers almost all areas of the earth. However, the satellite cannot observe the river bathymetry. LÄS MER

  7. 5. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sara Rosendahl; [2021]
    Nyckelord :Wastewater treatment plant; phosphorus precipitation; control strategy; feedforward; feedback; ASM2d and primary clarifier model.;

    Sammanfattning : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. LÄS MER
