1. Effects of summer peaks on brown trout and Atlantic salmon growth and survival in hydropower-regulated Gullspång River
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : Daily demands for electrical power are met through sub-daily release of turbined water in the form of hydropeaking. Hydropeaking’s changes to stream flow are listed as a threat to biodiversity in river ecosystems as it causes rapid habitat alteration such as increased depth and velocity, affecting the species living downstream.

2. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?
University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Abstract : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. READ MORE

3. Macroinvertebrate sampling in hydropeaking rivers : Testing Hester-Dendy samplers in a laboratory environment using different flow conditions
University essay from Karlstads universitet/Avdelningen för biologiAbstract : Degraded rivers and streams caused by disturbances have created a need for reliable tools to assess the ecological status of such ecosystems. Numerous methods and programs have been developed to assess ecological status using biological indicators, benthic macroinvertebrates are the most commonly used biotic indicator. READ MORE

4. How do functional riparian groups from northern Sweden respond to hydropeaking? : Short-term indoors study on germination, mortality and performance of Swedish riparian species from different species groups subjected to water treatments mimicking hydropeaking
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : With the ever increasing reliance on hydropower in the world, it is important that its effects on riparian vegetation is well understood. This study aimed to explore the effects of different forms of hydropeaking, which results from the rapid and frequent opening and closure of hydroturbines, on different species groups of riparian species native to northern Sweden.

5. Riparian vegetation responses to hydropeaking : Experimental study on germination and performance of plants along rivers regulated by hydropower dams in northern Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Riparian vegetation is one of the most complex and abundant ecosystems in the world and it provides important ecosystem services. These services are affected by electricity production from hydropower dams. Hydropower accounts for 16% of the global electricity production and almost 50% in Sweden. READ MORE
