Groundwater modeling and contaminant transport

Scenario 1: BTEX migration after 100 days
Scenario 2: BTEX migration after 1000 days
Scenario 3: BTEX transport after 7300 days

MODFLOW Computer Modeling

Figure 1. Particle tracking of contaminants
Figure 2. Transport of Chloride after 1000 days

This is a simple case scenario of groundwater flow and transport from a newly planned landfill. This is ONLY a simple 1 layer model that simulate the movement of Chloride (5000 mg/L) after 1000 days (3 years).

Selinsing Gold Mine

The Selinsing Gold Mine Project is located at Bukit Selinsing near Sungai Koyan, approximately 65 km north of Raub and 30km west of Kuala Lipis on the lineament known as the Raub Bentong Suture. Selinsing is located approximately 2 hours drive from Kuala Lumpur the capital of Malaysia on a sealed highway in Pahang State, which is the largest gold producing state in Malaysia. Some photos captured at the main entrance to the mine while passing thorough on the way to Cameron Highland with my MSc students.

My New Honda Freed

First long distance testing of my Freed. Photo captured in Bentong Mosque

Look how small is the car from the outside....but it has a bigger and comfortable cabin space inside (see photos below)

The inside view of Honda Freed. Very compact MPV with 7 seater and automatic sliding door on both sides. Very economical in fuel consumption. Small and compact car for a small guy with a big heart!

Sediment Monitoring of Putrajaya Lake 2011

Two sediment-monitoring exercises (water and sediment sampling & discharge measurements) were carried out during the months of January-February 2011 within the Putrajaya Lake & Wetlands complex. The sampling exercises were carried out on the 13 and 27 January 2011 and 16 February 2011 during moderately dry conditions. The sampling stations contain weir structures and culverts. 29 of these monitoring stations are located within the wetland arms and 10 are located around Putrajaya Lake.

SEAWAT Training at National Hydraulic Research Institute Malaysia (NAHRIM)

SEAWAT Training at NAHRIM on January 2011. The trainer was Dr Weixing Guo from Schlumberger, who is also the person that developed the software. Picture shows Dr Guo (in blue t-shirt) with Dr. Saim Suratman (Director for NAHRIM). SEAWAT is a generic MODFLOW/MT3DMS-based computer program designed to simulate 3-D variable density groundwater flow coupled with multispecies solute and heat transport.
