In 2011 a series of gauging stations was established along the Johor River which measured river water level and velocity to gain a better understanding of the existing river flows. The Johor River is an important source of water for several water treatment plants. However during high tides and in dry seasons, a salt water wedge pushes upstream affecting water quality and thus water supply.
Water management in the Sinar Mas Forestry plantations presents an immense amount of challenges. With over 2.6 million hectares of concession areas to manage, a comprehensive and dynamic water management plan is essential. For example, during the annual dry season, water table management is critical to prevent peat fires and for peatland forest conservation. However during the wet season, attention is switched to flood management at low elevation areas.

Hydrologists have long grappled with the dynamics of floodplains beyond the Mississippi's levees - do floodwaters travel over flooded cropland, or does the floodplain simply store water?
