1. 1. Evaluation of Streamflow Predictions in an Ungauged Swedish Catchment : A Study of Håga River

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

   Author : Hanna Pierrau; [2022]
   Keywords : Hydrology; Predictions in ungauged basins; Hydrological signatures; rainfall-runoff modelling; HBV; S-HYPE; hydrologi; uppskattningar i områden utan mätstation; hydrologiska signaturer; modellering; HBV; S-HYPE;

   Abstract : The Håga river, located west of the Swedish city Uppsala, is currently without a proper gauging station. Knowing the streamflow is nonetheless important to, for example, be able to calculate the nutrient transport in the river. READ MORE

3. 2. Characterization and modeling of hydrology and climatology in paramo ecosystems in Colombia : A study of the paramos and climate change impact on these ecosystems as a water resource

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

   Author : Lovisa Nilsson; Julia Tholander; [2022]
   Keywords : paramo; hydrology; climate change; precipitation; discharge; modeling; characterization; HBV; ENSO; paramo; hydrologi; klimatförändringar; nederbörd; avrinning; modellering; karaktärisering; HBV; ENSO;

   Abstract : Paramos are unique ecosystems situated in the tropical Andes at an elevation of 2800-4800 meters above sea level. They are home to a variety of endemic species and have a great water regulating capacity and supply around 80 % of the population in Colombia with freshwater. READ MORE

4. 3. Intelligent hydropower : Making hydropower more efficient by utilizing machine learning for inflow forecasting

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jakob Claesson; Sam Molavi; [2020]
   Keywords : machine learning; inflow forecasting; hydropower; HBV model; maskininlärning; tillrinningsprognostisering; vattenkraft; HBV-modell;

   Abstract : Inflow forecasting is important when planning the use of water in a hydropower plant. The process of making forecasts is characterized by using knowledge from previous events and occurrences to make predictions about the future. Traditionally, inflow is predicted using hydrological models. READ MORE

5. 4. Evaluation of CoupModel in Predicting Groundwater Levels

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Emil Fagerström; [2018]
   Keywords : CoupModel; HBV; groundwater levels; groundwater level modelling; forecasting; CoupModel; HBV; grundvattennivåer; grundvattennivåmodellering; prognoser;

   Abstract : The Geological Survey of Sweden (SGU) has initiated a project to calibrate models to simulategroundwater levels in monitoring wells of their Groundwater Network, based on a commission fromthe Swedish Government after experiencing historically low groundwater levels and shortage in 2016and 2017. A version of the HBV model with 4 parameters, focusing on calculating groundwaterrecharge and levels, was manually calibrated to 119 groundwater stations in 2017 and the modelresults were classified according to a ‘good’, ‘poor’ or ‘bad’ visual fit to observations.

6. 5. Modeling hydrometeorological extremes in Alpine catchments

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Theo Voulgaridis; [2017]
   Keywords : method of fragments; HBV; rainfall disaggregation; weather generation; hydrological modeling; modeling; översvämningsmodellering; hydrologisk modellering; vädergenerator; hbv-modellen;

   Abstract : Uncertainties with a modeling framework consisting of a weather generator, two precipitation disaggregation models and the hydrological HBV model was assessed with respect to hydrometeorological extremes in Tyrol, Austria. Extreme precipitation events are expected to increase in intensity and frequency in the Alps during a warmer climate. READ MORE
