Abstract
The canal planning in the south of the Wu River in Taiwan for water conservation and energy saving has been presented. In Taiwan, due to the special terrain and climate, the runoff time is too short to keep the water effectively. The annual precipitation in Taiwan is about 2.6 times the volume of the world average; however, available water resource per capita is far lower than the world average. On the other hand, according to Ministry of Transportation and Communication, greenhouse gases emission proportion rose from 8% to 15% from 1990 to 2000, mainly fueled by road transportation. Under energy shortage and climate anomaly, canal transportation has great advantage in carbon reduction. Nowadays, the canal not only serves the purpose of irrigation and transportation, but also flood control, tourism, ecology, and environmental protection. Furthermore, canals have great advantages in carbon reduction and water storage. The research was conducted in three phases. The first phase was processing collected data (precipitation distribution, river discharge, topography, land use investigation and etc.) with the geographic information system (GIS). Based on the information above, the canal route was planned in the second phase mainly by using suitable existing rivers, otherwise, artificial waterways. Then, route feasibility was assessed. However, because the plan in the phase two demonstrated low feasibility and high cost, in phase three, local canals were planned for urban development as an alternative to the proposal in phase two. To conclude, the length of the canal route in the south of the Wu River is 248.1 km, including 14 hubs and 17 navigation locks. The waterways in the route mainly were existing rivers. Compared to road transportation, carbon emissions in canal transportation was reduced by 68%. In addition, it had the water capacity of 24.7 million tons to serve as a means of water storage and extended the runoff time in the south of the Wu River.
