Research Report under the 12th Malaysia Plan Programme 4 – Study on Enhancing Water Supply Reserves Project Code: P3317000012009 – Hydrogeology Research Centre

Report Titles:

1. Enhancing Groundwater Reserves Through the Managed Aquifer Recharge (MAR) Approach in the Langat Basin, Selangor
2. Enhancing Groundwater Reserves Through the Managed Aquifer Recharge (MAR) Approach in Nenasi, Pahang
3. Enhancing Groundwater Reserves Through the Managed Aquifer Recharge (MAR) Approach in the Lower Kelantan Basin, Kelantan
4. Enhancing Groundwater Reserves Through the Managed Aquifer Recharge (MAR) Approach in the Melaka River Basin, Melaka
5. Enhancing Groundwater Reserves Through the Managed Aquifer Recharge (MAR) Approach in the Muda River Basin, Kedah
6. Enhancing Groundwater Reserves Through the Managed Aquifer Recharge (MAR) Approach in the Sedili Besar River Basin, Johor

Research Objectives:

i. To characterise the hydrogeological conditions of the selected river basins—including aquifer types, lithological composition, hydraulic properties, and groundwater flow systems—in relation to assessing the feasibility of MAR applications.

ii. To identify strategic locations for the development of wells based on geological, hydrogeological and hydrological criteria.

iii. To determine the estimated reserve margins of groundwater resources to ensure sustainable management.

iv. To estimate recharge capacity and storage potential within selected aquifer systems through infiltration modelling and analysis of hydraulic parameters.

v. To develop a conceptual framework for implementing MAR in the selected river basins, encompassing site selection criteria, recharge methods, and monitoring strategies aligned with national water resource management policies.

This research strengthens efforts towards resilient water resource management, enhances national water security, and supports the adoption of Managed Aquifer Recharge (MAR) as a long-term solution for selected river basins and their surrounding areas. The findings will contribute to sustainable groundwater development and improved adaptation to future water supply challenges.
