Groundwater is the fresh water contained in aquifers buried below the earth’s surface and is becoming vital natural resources for the nation nowadays. The demand of groundwater development in many countries is increases due to the limitation supplies of the fresh water on earth. However, due to the presence of rivers and abundance of rainfall in Malaysia, groundwater is given less priority as a source of water supply. This research studied on the hydraulic conductivity, K which is an important variable in groundwater transport flow. The data used in this study are two sets of secondary data collected by using auger-hole method with 2 different diameter measuring auger-hole near Jalan Sawah, Pekan Nanas, Pontian, Johor. The values of soil hydraulic conductivity were obtained by using Ernst and Hooghoudt formula. From the calculation, the range of hydraulic conductivity is between cm/s 0.3457 X 10-3 to 4.8135x10-3cm/s and it agrees that the hydraulic conductivity of peat soil that is between 1x10-4? cm/s to 1 x10-3cm/s. Besides that, this research also studies the effect of depth of water table and radius of auger hole toward hydraulic conductivity. The result obtained from multiple linear regressions shows that the depth of water table and radius of auger hole affect the hydraulic conductivity significantly. Lastly, stochastic approach was used to model the one dimensional, steady state and saturated groundwater flow and the exact solution is the expected function of the gradient of the head potential. |
