Peninsular Malaysia has various types of karstic limestone, sinkholes, solutioning cavities and channels. To effectively appraise the karstic formation, electrical resistivity and induced polarisation techniques have been proven a cost-effective solution for investigating subsurface bedrock profile, solution channels and its connectivity. A case study using 2-D electrical resistivity tomography and induced polarisation survey for a limestone quarry site is used to illustrate the successful application in identify the location of the karst features. Data processing has been carried out taking into consideration of the collective response of resistivity and induced polarization (IP)/chargeability that helps in interpreting subsurface strata, seepage path in the upper alluvial deposits, location of porous/jointed limestone rock mass or/and karst features with potential seepage flow, and the infilling condition of the joints and voids.","PeriodicalId":393867,"journal":{"name":"EAGE-GSM 2nd Asia Pacific Meeting on Near Surface Geoscience and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127935361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The geophysical method used in this study is 4-D electrical resistivity tomography (ERT), meanwhile soil mechanics used several laboratory tests, namely direct shear, moisture content, porosity, plastic limit and liquid limit. The infield survey using 4-D ERT was conducted for three different months and soil samples were collected along the survey line. The model resistivity with topography obtained showed all the ERT results gave a good results with RMS error between 2.4 - 2.4 %. Based on the model resistivity results, the subsurface of slope area can be divided into two main zone, dry clayey sand soil (100 - 550 ohm.m) and clayey sand soil (550 - 1300 ohm.m). The model resistivity results showed there are changes in electrical properties of soil, which associated with the moisture content, porosity and structure of soil itself during the three months of investigation period. In conclusion, the integration of both ERT and soil mechanics methods are capable to investigate the clayey sand soil’s properties and its behaviour during three months period.","PeriodicalId":393867,"journal":{"name":"EAGE-GSM 2nd Asia Pacific Meeting on Near Surface Geoscience and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122617754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the acquisition of groundwater exploration, Schlumberger Vertical Electrical Sounding (VES) is the most preferred due to convenience and effectiveness. Schlumberger configuration will produce a subsurface profile vertically at an observation point and is the initial step to estimate the presence of aquifers in the groundwater exploration area. However, this method has several geological considerations leading to the inaccurate subsurface interpretation that the presence of dipping layers and subsurface structures such as fault are the main factors. Thus, the presence of that features can affect the modeling of resistivity values and subsurface thickness during interpretation process of the resistivity method. This then becomes the basis of the authors conducting a study that aims to determine the accuracy of the layer thickness produced by the VES resistivity method. However, the existence of subsurface structures is also difficult to predict if there are no supporting by surface data, hence the study modeling of subsurface conditions using a sandbox model will be carried out.","PeriodicalId":393867,"journal":{"name":"EAGE-GSM 2nd Asia Pacific Meeting on Near Surface Geoscience and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128520898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
