ANALISA AKIUFER BEBAS KOTA PEKANBARU DENGAN MENGGUNAKAN METODE BEDA HINGGA

Abstract

Research on the analysis of the unconfined aquiver Pekanbaru city has been doneusing finite difference method. The unconfined aquifer depth data and locationcoordinates are taken in every district in the city of Pekanbaru each consists of 4samples. The purpose of this study was to analyze the condition of the unconfinedaquifer 2016 to 2019 in every district in the city of Pekanbaru by using a computerprogram MATLAB application version 7.0. Based on this research can be informedthat the condition of the unconfined aquifer in every district in the city of Pekanbaruare as follows: The Unconfined aquifer condition is in good condition located in theDistrict Marpoyan Peace with an average depth of the aquifer independent from 2016and 2019 respectively -8.15 to -1.12 meter. The Unconfined aquifer conditions thatmost damaged districts are in the depth of the unconfined aquifer Rumbai average of2016 to 2019 respectively is 54.52 meters to 54.24 meters.
