Tachia River
Dajia River () is the fifth-longest river in Taiwan located in the north-central of the island. It flows through Taichung City for 142 km. The sources of the Dajia are: Hsuehshan and Nanhu Mountain in the Central Mountain Range. The Dajia River flows through the Taichung City districts of Heping, Xinshe, Dongshi, Shigang, Fengyuan, Houli, Shengang, Waipu, Dajia, Qingshui, and Da'an before emptying into the Taiwan Strait. The Deji Reservoir (), formed by Techi Dam, is a 592-hectare reservoir in Dajia District. The reservoir provides municipal water, generates hydroelectric power, is used for recreation and prevents flooding. Techi and a cascade of five other dams on the Dajia produce up to 1,100 megawatts of hydroelectric power and generate more than 2.4 billion KWh per year. The other five dams in sequence from top hill are Qingshan Dam, Kukuan Dam, Tienlun Dam, Ma'an Dam and Shigang Dam. Taiwan's Central Cross-Island Highway runs along the Dajia River from Heping ...

Techi Dam
Techi Dam () is a concrete thin arch dam on the Dajia River in Heping District, Taichung, Taiwan. Forming the Techi Reservoir (德基水庫), the dam is built in the Tachien Gorge in Heping District, providing hydroelectric power, irrigation water, and some flood control, and is operated by the Taiwan Power Company. At , it is the highest dam in Taiwan and one of the tallest dams in the world. The dam was completed in 1974 after five years of construction. History Proposals to dam the Dajia River date back to the period of Japanese colonial rule in Taiwan (1895–1945), when dams were envisioned to generate 430 megawatts (MW) of power on the river. In 1936, the Taiwan Power Company began to survey and collect data at this site, but there would be a gap of more than ten years between Taiwan's 1945 independence from Japan and the beginning of development on the Dajia River. The downstream Tienlun and Kukuan dams were built in 1956 and 1961 respectively, but with their small sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Earthflow
An earthflow (earth flow) is a downslope viscous flow of fine-grained materials that have been saturated with water and moves under the pull of gravity. It is an intermediate type of mass wasting that is between downhill creep and mudflow. The types of materials that are susceptible to earthflows are clay, fine sand and silt, and fine-grained pyroclastic material.Easterbrook, D: “Surface Processes and Landforms”, page 78-79. Prentice-Hall, Inc, 1999 When the ground materials become saturated with enough water, they will start flowing (soil liquefaction). Its speed can range from being barely noticeable to rapid movement. The velocity of the flow is dictated by water content: the higher the water content is, the higher the velocity will be. Because of the dependency on water content for the velocity of the flow, it can take minutes or years for the materials to move down the slope. Features and behavior Earthflows are just one type of mass movement that can occur on a hill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central Cross-Island Highway
The Central Cross-Island Highway () or Provincial Highway 8 is one of three highway systems that connect the west coast with the east of Taiwan. Construction The construction of the Central Cross-Island Highway began on July 7, 1956 and was first opened to traffic on May 9, 1960. Route The route of the highway begins in the west at Dongshi District in Taichung. The highway originally continued up into the Central Mountain Range following the Dajia River valley through the townships of Guguan (谷關) and Cingshan (青山). However, the section between Guguan and Lishan is permanently closed to non-residents due to earthquake and typhoon damage. At Lishan there is a branch that heads north to Yilan City. Passing through the mountains it reaches Dayuling (大禹嶺) which is the highest point of the route. Here another branch of the highway runs south from Dayuling to Puli via Wuling (武嶺). Continuing east from Dayuling the highway route now begins its descent into th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shigang Dam
Shihgang Dam () is a concrete gravity barrage dam across the Dajia River in Shigang District and Dongshi District of Taichung, Taiwan, located near Fengyuan District. The dam was built from 1974 to 1977 for flood control and irrigation purposes, and stands high and long, holding a reservoir with an original capacity of . The dam was heavily damaged in the 921 earthquake of 1999, which caused the collapse of its northern end. Subsequently, an embankment cofferdam was built to prevent water from flowing through the breach, while the collapsed section has been retained as a memorial. Since this reduces the storage capacity of the dam, it is no longer used for flood control, but remains an important source of agricultural water.
