Introduction to the itinerary

Huisun Forest Recreation Area

Huisun experimental forest area is an experimental forest farm of National Chung Hsing University, with a forest area of 7,477 hectares, located in Nantou County, Taiwan. Due to the 2000-meter altitude difference in Huisun, from 450-2,420 m, the forest is longitudinally scattered between peak and valley, and so the main features of the climate can be divided into tropical, subtropical and warm regions. Each region consists of a variety of vegetation with adaptive plants. The varieties of plants in the 3 regions is a result of the multi-variety ecological system.

Dammed-lake failure experiment in Huisun Forest Recreation Area

How does the water flow of the dammed lake vary during the dam breach? Nobody knows. Because in the process of dam breaching, almost no one was on the scene. Therefore, we would very much like to reveal the puzzle through the experiment that how the disaster formed. How large is the submergence range caused by the breaching flow? And when does the peak discharge occur? In order to have a better understanding of the breaching process of barrier dam and the disasters characteristics caused by floods and sediments during the failure. Professor Su-Chin Chen from the Department of Soil and Water Conservation of National Chung Hsing University and his research team established the world's first full-scale barrier dam breach test site, restored the scene of the disaster in the Landao Creek, Huisun Forest Recreation Area.
Introduction for Dammed-lake failure experiment:


The Gonglaoping community follows the principles of the " Satoyama Initiative", and jointly maintain and preserve the stone masonry production landscape of the persimmon garden through the Industry-Academia-Government cooperation. In addition, the Soil and Water Conservation Bureau has widely set up farm ponds and solar energy to store and recycle water to solve the local drought problem. The community has also independently established a water environment patrol team to reduce the use of pesticides and adjust the use of water resources to maintain the ecological and economic balance of the persimmon garden production landscape through industrial marketing activities in spring, summer, autumn and winter.

The Torrent Regulation Project of Sijiaolin in Dongshi Forest Garden

1. Local scour found in the upstream and downstream of Check Dam.
2. High drop of dam created habitat discontinuity.
3. Bank erosion enhanced soil loss.
4. Habitat destruction caused decreasing of fireflies.
5. Erosion of right bank become dangerous area for tourist.
Remediation Task:
1. Six Wildlife Passageways
2. Repair and Improvement of Check dam
3. Soil-bag Intercepting ditch: 180m (include two ponds)
4. Protection Engineering of Right bank: 284.5m
5. Reinforcement of slope toe on left bank: 166.5m
6. Flow path of low discharge: 150m
7. Groundsill: 10
8. Revetment: 56m
9. Stair for energy dissipation & water storage: 1

ACE Geosynthetics Eco Park

ACE Geosynthetics Eco Park covers an area of 10,000 m2, with "disaster prevention", "ecology", "landscape", "low carbon", "green energy" and "water resources" as the six major axes of the park's construction. The park is divided into 10 landscape image areas and displays 26 green construction methods. It is the first full-scale physical green project exhibition park in Asia. The park also combines the innovative application platform website to provide experts and scholars from industry, government, academia and research to further understand the connotation and specific practices of sustainable green engineering, and create more education and knowledge promotion value for sustainable green engineering.

National Taichung Theater

National Taichung Theater was designed by well-known architect Toyo Ito. The theater is mainly composed of undulating curved walls, forming large and small caves. It is designed with the concept of the most primitive "tree house" and "cave". The walls are all curved, with a total of 580 curved walls, which are extremely difficult to construct. In addition, the large glass curtain and the borderless space make the theater an open building that integrates the inside and the outside and returns to nature.
