Study of Yeh Embang Watershed Characteristics for Sustainable Water Management

Abstract

One of Bali’s perennial watershed that is experiencing the effects of climate change is the Yeh Embang Watershed. If it is not managed holistically, the sustainability of the current water availability will be impacted. This research will analyse the Yeh Embang Watershed’s characteristics in order to evaluate the watershed’s condition and decide how to manage the sustainability of the water resources. For this research, topographic information, boundary maps of the Yeh Embang watershed, maps of river network, maps of land use, and maps of soil types were all used. The appropriate sustainable management for Yeh Embang Watershed should be determined based on the characteristic. According to the characteristics of the Yeh Embang Watershed, integrated management from upstream to downstream be necessary for the watershed to be managed sustainably. In the upstream area, it is hoped that the forest will be protected by forest conservation to reduce the risk of erosion that could lead to flash floods, and the downstream portion of the Yeh Embang watershed will be structured to prevent flooding from harming the surrounding area. Infiltration wells can be used as a water-saving measure in residential areas in the Yeh Embang watershed to increase the amount of water that is absorbed and lessen surface runoff.
