The General Department of Geoscience (JMG) also conducted the borehole drilling in Kampung Semerbok, Rembau and Felda Bukit Rokan Utara ( Appendix A). The third layer was schist with 91 m thickness. The first layer was reddish clay with thickness 3 m and second layer was 6 m whitenish clay. The drilling depth was until 100 m and the drilling show three layers. The truck mounted rig drilling machine was used and conduct with down the hole hammer method. The General Department of Geoscience (JMG) conducted the borehole drilling in Kampung Bangkahulu, Gemas as shown in Appendix A.
#RES2DINV TUTORIAL SOFTWARE#
The (XYZ) format used as input data for Voxler software to generate 3D visualize picture. The schematic layout of the electrode arrangement and connections is displayed in Fig. 2.īy RES2DINV Software, the raw data of electric resistivity was converted to (XYZ) file and saved as showing in Fig. 3. The data collected in the survey is then converted to image using RES2DINV software. As the connections of lines completed and Terrameter were set up, all data was automatically recorded by the Terrameter SAS 4000 and LUND Imaging System and the data was saved in the Terrameter main unit before transferring to computer. Electrode number 1 (E1) and electrode number 81 (E 81 for the first and second site) and Electrode number 41 (E41 for the third site) must be defined. Fig. 1 show the locations of the resistivity test were conducted and the coordinates of the resistivity survey line are showing in Table 3. The whole line of electrical resistivity investigation line is 400 m for the first and second site and 200 m for the third site where 5-m spacing. The electrode was coupled to resistivity land cables via jumper cable. The third location (Felda Bukit Rokan Utara), (41) numbers of electrode was used and (2) resistivity land cables each one is 100 m with same configurations (Schlumberger). For the site Kampung Bangkahulu Gemas and Kampung Semerbok, Rembau, Schlumberger configurations was used with (81) numbers of electrode and (4) resistivity land cables each one is 100 m. 907–910.Ģ. Experimental design, materials, and methodsĪ 2-D electrical resistivity imaging method was employed in this work with a multi electrode resistivity meter system. Mukri, Geophysical measurement for estimation of groundwater hydraulic properties. The electrode was connected to resistivity land cables using jumper cable. Schlumberger configurations was used with (81) and (41) numbers of electrode and resistivity land with 100 m length. Raw data analyzed by RES2DINV & VOXLER software. ABEM SAS 4000 equipment produce Electrical Resistivity Imaging Raw data
