E-flow Phase II: Training on E-flow Guideline

The Water Resources Coordination Division conducted a training workshop on the E-flow Guideline as part of the project ‘Study on Minimum Environmental Flow for Hydropower Projects in Bhutan – Phase II’ from March 24-26, 2021. The project is funded by the Austrian Development Agency and is implemented by the National Environment Commission Secretariat in collaboration with key stakeholders, from November 2019 to April 2022.

The training was attended by officials from the Department of Agriculture and National Research Centre for Riverine Lakes and Fisheries, Department of Livestock (MoAF), Department of Hydropower and Power Systems (MoEA), Bhutan Electricity Authority, Druk Green Power Corporation Limited, Ugyen Wangchuck Institute for Conservation and Environmental Research, College of Natural Resources and Sherubtse College. Participants from the College of Science and Technology along with the international experts attended the workshop virtually.

On Day 1 of the training, sessions on preparatory works and site selection; hydrology and hydraulics; and data collection in terms of topography, bathymetry, hydraulic and socio-economic components were provided. On Day 2, equipment such as the acoustic doppler current profiler, total and base stations, and unmanned aircraft system procured through Phase I of the project were demonstrated. Sessions on 2D hydraulic modelling and habitat modelling were also undertaken. On Day 3, representatives from Druk Holdings and Investment Limited demonstrated their Smart Water Management prototype, which is a part of their Smart City venture (more information at https://innotech.dhi.bt/). Sessions on cumulative impacts and scenario generation; watershed and sediment management; and fish data collection were also conducted on the day. All of the sessions were facilitated by key relevant international experts and local officials trained through Phase I of the project.

The training was intended to be a refresher course covering all the aspects of the E-flow methodology as listed in the endorsed Guideline.
