The first two days of the workshop were held at Tsinghua University in Beijing and included four sessions with scientific presentations, followed by discussions and group work.
The topics of the workshop presentations included among others:
The discussion and group work part was divided into a general discussion and specific discussions in smaller groups, with focus on the following important research tasks:
After the visit at Tsinghua University, the researchers went by plane from Beijing to a site visit at Fengman Hydro Power Station (HPS), situated close to the city of Jilin in North-East China. There they were taken on a bus trip to Fengman HPS, with stops at the re-regulation dam downstream from the HPS (which is used to dampen the hydropeaking effects), at the HPS's museum and Fengman dam.

The field trip peaked out with a boat excursion at Fengman lake. On the next day, a meeting with Fengman Power Company was held at Century Hotel Jilin. It included an introduction of Fengman station and a discussion of the specific environmental issues related to the dam project.

The Fengman dam was built by the Japanese in 1937-42 as part of the hydro-power development for their puppet state Manchuko. The dam was damaged toward the end of World War II and almost all of the hydroelectric plant was removed to the Soviet Union. After 1949, the Chinese government conducted restoration works. The dam was extended and strengthened and the power generation equipment was restored with Soviet aid. However, there were still problems with dam safety, despite to several upgrades and reinforcements. Therefore it has been recently decided to build a new dam 120 m downstream of the original dam. The original station's functions will be recovered without changing the reservoir's characteristic water level. Six new sets of 200 MW Francis turbine generator units will be built, and two older units will remain. The new total capacity will reach 1480 MW. It is planned to use 10-15 % of the budget for environmental measures, such as fish passages.
