Challenge

  • The rise in sea levels due to climate change increases the risk of flooding in coastal areas and small islands by causing sea water inundation and increasing extreme rainfall. This threatens infrastructure and human settlements. There is a need for mitigation, adaptation, and wise spatial planning to protect communities and the environment from the adverse impacts of floods.

  • High-level water monitoring technologies such as manual gauges and tide gauge stations have limitations in accuracy, range, and real-time capability, thus requiring the development of more advanced technology to monitor water levels in real-time and accurately.

Study Case

Installation of AWLR for River Water Level Fluctuation Monitoring together with the Public Works and Housing Department (PUPR) of Kediri City, East Java.

​In March 2024, the Mertani team implemented the Automatic Water Level Recorder (AWLR) installation project in Kediri City, East Java. In this project, they successfully installed 6 units of AWLR at five strategic locations along the river that crosses the city. The main objective of installing AWLR is to enhance the quality of river water level fluctuation monitoring efficiently and effectively. Therefore, it is expected that the generated data will provide more accurate and up-to-date information about the river conditions, as well as support better water resource management in the area.

Study Case

Installation of Automatic Water Level Recorder for Oil Palm Plantation Management in North Sumatra

In March 2024, Mertani installed Automatic Water Level Recorders (AWLR) in an Oil Palm Plantation in Medan City, North Sumatra. They installed a total of 3 units of AWLR at different locations within the plantation. The purpose of installing these devices is to enhance the efficiency and effectiveness of water level monitoring within the plantation. By monitoring water level fluctuations in real-time, it is hoped to aid in making better decisions regarding water management in the oil palm plantation. This initiative represents a proactive step by Mertani in supporting sustainable and efficient farming practices in the region.
