  1. 6. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Johan Elfing; Daniel Persson; [2022]
    Keywords : CatFish; Embedded System;

    Abstract : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. READ MORE

  3. 7. 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

  4. 8. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

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

    Author : Sara Camiolo; [2021]
    Keywords : eutrophication; rivers; streams; phosphorus;

    Abstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

  6. 10. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Oskar Evert Johansson; [2021]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE
