1st Geo-Environment Talk

First Geo-Environment Talk was held on Thursday, January 19, 2012 at Geology Meeting Room in UKM. The talk was given by Dr. Nik Norsyahariati Nik Daud from Universiti Putra Malaysia. She graduated from Geoenvironmental Research Centre (GRC) in Cardiff University under the supervision of Prof Hywel Thomas.

Effect of pumping on the contaminant transport model

This simulation was made on a landfill that constantly discharge 50mg/L of Pb. The landfill was modeled using visual Modflow, considering a linear sorption, with an initial Pb as 100mg/L, the model shows the effect of pumping on the Pb transport. The pumping rate was 1000m3/day.

a) after 10 days of pumpingb) after 100 days of pumping

c) after 300 days of pumping

3-D Contaminant Transport Modeling using Visual MODFLOW Pro

Groundwater flow and contaminant transport modeling was performed using Visual MODFLOW Pro on a Landfill in Kuala Lumpur (Malaysia). The study has successfully delineate the contaminant migration pathway and 3-D models were developed to visualize these contaminant pathways.
(i) 2-D Model of contaminant transport(ii) 3-D model of contaminant transport after 2050 days (about 5.7 years)

(iii) 3-D model of contaminant transport after 7200 days (20 years)
