Abstract/Summary:
In this study we introduce the Greenchannel, which is a unique research facility that brings together river scientists, engineers, and managers to explore river flows and riparian ]ones, particularly downstream from large hydropower plants. The Greenchannel will help to understand the underlying physical, biological, and chemical mechanisms that govern stream processes and their response to natural and human disturbances. This knowledge is critical to develop science-based approaches for managing and restoring the degraded rivers. The Greenchannel mimics a life-sized, indoor, regulated river reach, and is inspired by the integration of a hydraulic channel and a greenhouse. ,t consists of a water storage tank, and a channelcircuit where water circulates constantly and can vary arbitrarily its level, velocity and flow, variables that are particularly affected by hydropower production scenarios leading to the phenomenon of hydropeaking. ,n a margin of the channel a riverbank area is arranged on a mixture of natural soil. The whole facility is located inside an industrial-type, baseless greenhouse that guarantees the experimentation with riparian ]ones allowing the control of the inside temperature, light, and humidity, among others. The Greenchannel is uniquely equipped to conduct hydraulic, hydrological and instream and riparian ecological life-sized experiments under controlled conditions impose and repeat all kinds of hydrographs, including overbank floods quantify physical, chemical, and biological processes taking place both in the river and in the associated riparian areas from microscopic to reach scales provide verification for advanced computational models and host highly visible formal and informal education. In this work we want to publicise this facility, e[plaining from its design and hydraulic operation to its multiple possibilities for scientific experimentation.
