Integrated Lake Basin Management (Ilbm) of Hydrological Assessment Characteristics in Kenyir Lake Basin, Terengganu, Malaysia

Abstract

Lake water is a vital resource in supporting life, which is important for the ecosystem of both flora and fauna. Monitoring lake-related programmes based on methodical decision-making and management tools are necessary for the sustainable use of lake water resources. This research's objectives include analysing the characteristics of hydrological quality to identify the current condition of the physical environment of the Kenyir Lake Basin, and providing integrated management methods for its water resources. 21 monitoring stations were chosen for sampling in three seasons (normal season, wet season and dry season) throughout the Kenyir Lake Basin. This study evaluates both in situ and ex situ methods for water quality, followed by a lab test according to American Public Health Association (APHA) standards. Water velocity is a major factor in erosion and the production of sediment, and it is determined by the quantity and intensity of rainfall. It is discovered that there is a significant deterioration in the quality of the water, elevating the rate of erosion with the remarkable water velocity and volume. Aside from that, the rapid urbanisation and population growth in Malaysia is contributing to an increasing level of pollution in the nation's lakes. The ILBM-based adaptive management solutions are adaptable and capable of adjusting to shifting environmental circumstances, which help in revising management plans based on data-monitoring as well as stakeholder feedback.
