Abstract
This research presents a concept of planning a canal in the north of Wu River in Taiwan, which includes the motivation and the process of planning the canal. Canals’ functions of irrigation and transportation in the early days have extended to today''s water storage, flood control, recreation, tourism, ecology, and environmental protection. Especially under energy shortage and climate anomaly, canal transportation has the great advantage in carbon reduction. The main purpose of this research is to plan the most feasible canal to improve water utilization and reducing Taiwan''s carbon emissions caused by transport. The reasons of planning canal can relate to the low using efficiency of water resource and the high growth rate of greenhouse gas emission. In terms of Taiwan, in the part of water resource, the annual average precipitation is about 2.6 times the volume of the world average, while average annual allocation of water per person is far lower than the worldwide average; in the part of carbon emissions, according to Taiwan''s energy balance sheet data, greenhouse gas emission proportion from the transportation sector rose from 8% to nearly 15% in 1990 to 2000, which mainly grew in the buses and trucks. The process of planning canal in the north of Wu River in Taiwan can be divided into three stages. The first part is to collect and organize information including rainfall, rivers, geology, topography, investigation of land using etc. and then process the data into layers which are accessible to the geographic information system (GIS). The second part is planning the canal in the north of Wu River in Taiwan based on the information collected including selecting appropriate existing rivers, analyzing the terrain along panning route and assessing the feasibility etc. The third part is planning local canals for the cities in the north of Wu River in Taiwan. Since the second part of the canal project involves too many expensive engineering projects, the overall feasibility of implementing it is not high; consequently, planning local canal to enhance the feasibility. The local canals mainly were planned to bring out the functions of flood control and tourism with reference to geographic environment, human and social development, land using and urban planning division. In the conclusion of the planning canal in the north of Wu River in Taiwan, the length of the canal route is 191 km, which includes 170.5 km of existing rivers, 0.65 km of artificial waterways, 21 km of by-pass tunnel and 19 navigation locks. Compared to the road transportation, the carbon emissions in canal transportation were reduce to 30 %.
