Groundwater Modelling

MWES Consulting have developed numerical groundwater flow models using MODFLOW software on several water supply and mine dewatering projects:

· Siana Gold Project, Philippines
· Didipio Copper Gold Project, Philippines
· Co Dinh Chromite Project, Vietnam
· Grey Mare, Charlie Roy Valais borefields, Minara Resources, WA.

MWES consulting have also used the SUTRA 2D/3D modelling software to predict movement and recovery of dense contamination plumes as well as energy flow in a geothermal project.

MWES Consulting have conducted surface water and groundwater surveys on various agricultural properties throughout Western Australia. These surveys included estimation of average and peak surface water runoff and water well testing. Surface water runoff and sediment erosion for both agricultural and urban projects can be modelled using the following software:
· SWMM – Storm Water Management Modelling
· WEPP – Water Erosion and Run off Prediction
· CLIGEN – Climate Generator Program
· HY8 – Culvert Design and Analyses
· HY22 – Visual Urban Drainage Design
· MapInfo Geographical Information Systems
