| Summary: | The purpose of this assessment is to assess the subsurface condition of peat soil due
to brackish groundwater seepage using a numerical method. This water comes from
pumping activities and will fill up the earth drain. The Department of Irrigation and
Drainage (DID) build the drainage to help extinguish peat fire in the study area where
the water will spread out into the peat soil and, hence, moisturize the soil. This
assessment uses Visual MODFLOW to visualize the condition in the study area and
produce the outcomes related to the objectives of the study. The results of the
simulation show that there is only a small portion of high salt concentration along the
drainage. The migration of salt concentration is affected by the groundwater head and
velocity vectors of the aquifer materials. Meanwhile, the high salt concentration from
the sea focuses along the coastline. Most of the other places in the study area receive a
low salt concentration. Therefore, the impact of brackish groundwater on the
environment is not significant since the salt concentration is low in most of the study
area. |
