Effectiveness of Geoelectrical Resistivity Surveys for the Detection of a Debris Flow Causative Water Conducting Zone at KM 9, Gap-Fraser’s Hill Road (FT 148), Fraser’s Hill, Pahang, Malaysia

Table 3

Attribute of various zones based on resistivity values.

Number	Zoning symbol	Description
1	a	Resistivity values above 5000 Ωm, are the fresh granite rock mass
2	b	Resistivity value between 3000 Ωm–5000 Ωm, granite slightly weathering and highly fractured
3	c	Residual soil (IAEG, V-IV) (600 Ωm–3,000 Ωm)
4	d	Water conducting zone or high water content (<600 Ωm)
