1. 1. Acoustic Doppler Current Profiling for streamflow measurements in subarctic climate

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Linus Nyström; [2022]
   Nyckelord :;

   Sammanfattning : The ADCP (Acoustic Doppler Current Profiling) technology has been widely available and acknowledged as an instrument used for different types of flow measurement since 1990s, from small scale river measurements to larger ocean current mappings. This study was conducted by the author in cooperation with SWECO with the focus on smaller scale measurements especially on small natural watercourses in a sub-arctic climate with the purpose to examine if the ADCP technology can be used as a complement to the more classic methods for this type of flow measurements Current meter and Conductivity flow measurements.

3. 2. Improving stream flow estimation in a montane rainforest stream in Costa Rica : The impact of adding a high flow estimation

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

   Författare :Martin Dahlin; [2022]
   Nyckelord :Streamflow information; Manning s estimation; rating curve; hydrographs; Vattenföring; avbördningskurva; hydrograf; Mannings ekvation;

   Sammanfattning : A key piece of information necessary for water management is accurate streamflow information. However, the available data and resources for gathering information vary around the world. LÄS MER

4. 3. Investigating eco-hydrological relationships between fishes and flow regimes in Spanish rivers

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Celia Ramos Sanchez; [2021]
   Nyckelord :Eco-hydrological relationships; Fish metrics; Hydrological metrics; Environmental flows; Hydrological alteration; Technology and Engineering;

   Sammanfattning : There is currently a need in Spain for monitoring the effects of the environmental flows. The use of eco-hydrological relationships to design both environmental flows regimes and the monitoring programs that track their effects on riverine ecosystems is highly recommended. LÄS MER

5. 4. Regional Regression Models of Mean Annual Streamflow and Design Flow in a Tropical Region of Colombia.

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Anisa Zigaf Elfellah; Amanda Eriksson; [2018]
   Nyckelord :mean annual streamflow; extreme flow; design flow; regional regression model; ungauged watershed; hydrological homogeneous region; Gumbel distribution; Technology and Engineering;

   Sammanfattning : A responsible and sustainable water resources management is important. It is also crucial to take the presence of watercourses into account during design of hydraulic structures such as small dams and bridges. Doing this requires knowledge of estimates of annual streamflow and extreme flows to be used for design purposes. LÄS MER

7. 5. Evaluation of Seasonal Inflow Forecasting to Support Multipurpose Reservoir Management: A case study for the Upper Maule River Basin, Chile

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Johan Visser; [2017]
   Nyckelord :Seasonal Forecasting; Reservoir Management; Ensemble Streamflow Prediction; Downscaling; Maule; Earth and Environmental Sciences;

   Sammanfattning : Seasonal hydrological forecasts of future streamflow volumes can provide water resources managers with valuable information to improve long-term water resources planning and water use efficiency. The latest generation of coupled ocean-atmosphere general circulation models provides an opportunity for the prediction of hydroclimatic variables (e.g. LÄS MER
