Model Tiga Dimensi Kedalaman Air Bawah Tanah Di Bawah Pengaruh Faktor-Faktor Lingkungan Yang Terintegrasi
Research on three dimensional models of the depth of underground
water under the effects of integrated environmental factors has been
successfully done. Groundwater used by residents, industry, public facilities,
agriculture, livestock, and traditional market can affect the depth of
underground water conditions. The purpose of this research is to obtain three
dimensional map of underground water depth againts environmental factors
in Pekanbaru City using computational mathematica program. The data were
collected from every sub-district in Pekanbaru City from the year of 2013 to
2017 with several environmental factors that influence the depth of
underground water. The environmental factor studied in this research are
resapan (R) data, taking by residents (Ed), industry (Ei), public facilities (Ef),
raising livestock (Ek), agriculture (Et), traditional market (Ep), and aquifer
factor namely transmisivity (T) and Storativity (S). Based on the results of the
study it can be informed that changing in free aquifer depth in Pekanbaru City
from 2013 until 2017 results the fluctuating in free aquifer depth. The lowest
depth in underground water of each sub-district in Pekanbaru City from 2013
to 2017 is 2 s / d 10 m for Payung Sekaki, Sail and Pekanbaru Kota, while the
highest depth is 2 to 50 m for Tenayan Raya District, Lima Puluh, Tampan,
Sukajadi, Marpoyan Damai, Senapelan, Rumbai Pesisir, Bukit Raya, and
Rumbai.
Value in underground water depth is mainly due to environmental
factors with the smallest contribution comes agricultur (Et), while the largest
contribution of water comes from traditional market (Ep), the others are due to
natural factors. The 3 dimensional model has been successfully explained the
effect of integrated environmental factors on the change of ground water
depth in Pekanbaru City from 2013 until 2017.
