SIMULASI PENGARUH LITOLOGI TERHADAP MODEL SISTEM AKUIFER BEBAS ( Studi Kasus Kecamatan Tampan Kota Pekanbaru )

Abstract

The simulation of lithology effect on the model of uncofined aquifer system (a case study at
Tampan-Pekanbaru) has been done. The aim of this study is to analyze the effect of lithology
on model of uncofined aquifer system using a computer program which is called MATLAB
R2009a. The output of this computer program is in the form of depth of uncofined aquifer or
hydraulic head value. The results showed that the depth of uncofined aquifer varied from
2.187 meters to 8.2709 meters. It was also found that the value of transmissivity and
storativity of lithology gravel were 5175 m2/day and 287.8 respectively. While the value of
transmissivity and storativity of lithology fine grained stone 2.3 m2/day and 241.5
respectively.
