Micro Hydroelectricity Using Irrigation Ponds for Better Water Management

Abstract

This paper discusses estimates of hydroelectricity potential using irrigation ponds in mountainous areas. Hydroelectric power output is calculated from hydrological observations such as discharge from the ponds and water level at two irrigation ponds. Although these ponds have almost the same water storage capacity, water discharge patterns differ due to differences in the command areas. Results show that water management influences the pattern of hydroelectric power generation. The use of electricity is also important to consider since irrigation ponds in mountainous areas are distant from villages, which have no electricity infrastructure. In most cases, the irrigation ponds in mountainous areas are difficult to access. In addition, most of the water managers are aging and are having difficulty maintaining irrigation ponds and its water management. Therefore, using hydroelectric power to support the operation and maintenance of irrigation ponds would be one of the best ways to use the hydroelectric power generated at irrigation ponds. Finally, a field experiment of a micro-hydroelectricity system is conducted at an irrigation pond and the pond monitoring system is installed.
