The Transient Electro-Magnetic (TEM) geophysical technique was deployed to map and characterized the subsurface of Pahang River Basin along the East Coast Peninsula Malaysia. The data aimed at differentiating between the massive zones and the weak zones within the region, to also assess and differentiate the subsurface structures and comes up with recommendations for policy decision, formulation and plans on the flooding impact, surface water and groundwater managements, in addition to other environmental related issues ravaging the area. The data presented in this paper, showed the properties of the subsurface rocks underlain the region as beneficial to the Agriculturists; Climatologists; Engineers; Environmentalists; Geoscientists, Hydrologists and Policy formulation officers. The TEM data collection utilized a 100 m x 100 m single loop coil for both the Transmitter (Tx) loop and the Receiver (Rx) loop to produce a total surface area coverage of 10,000 m per survey line along a single profile. The total area covered in the data extended across an average area of 30 km x 40 km in parts of Maran, Temerloh and Jerantut districts, within the State of Pahang, East Coast, Peninsula Malaysia. The conductivity data recorded varied from -20 mS/m to about 440 mS/m at a maximum depth of about 375 m. On the other hand, the resistivity data recorded varied from 0 Oh-m to about 1000 Oh-m. The information derived from the data are intended for potential abstraction by the Malaysian Groundwater Management Board; the Department of Mineral and Geoscience; Department of Irrigation and Drainage; the Pahang State Water Board, and the Department of Agriculture.
瞬变电磁（TEM）地球物理技术被用于绘制马来西亚东海岸半岛彭亨河流域的地下情况并对其进行特征描述。数据旨在区分该区域内的块状区域和薄弱区域，评估和区分地下结构，并就洪水影响、地表水和地下水管理以及该地区面临的其他环境相关问题提出政策决策、制定和规划建议。本文所呈现的数据表明，该区域地下岩石的特性对农学家、气候学家、工程师、环境学家、地球科学家、水文学家和政策制定官员有益。TEM数据采集在发射（Tx）线圈和接收（Rx）线圈中均使用了100米×100米的单环线圈，以在沿单个剖面的每条测量线上产生10,000平方米的总地表覆盖面积。数据覆盖的总面积在马来西亚东海岸半岛彭亨州的马兰、淡马鲁和文冬部分地区平均延伸30千米×40千米。记录的电导率数据在最大深度约375米处从-20毫西门子/米变化到约440毫西门子/米。另一方面，记录的电阻率数据从0欧姆·米变化到约1000欧姆·米。从数据中得出的信息供马来西亚地下水管理委员会、矿产与地球科学部、灌溉与排水部、彭亨州水务局和农业部进行潜在提取。
