Stormwater drainage design involves the planning and construction of systems to manage the flow of rainwater and prevent flooding. A stormwater drainage system provides a means of conveying rainwater from roads, buildings, and open areas into a public stormwater drainage network. Our firm uses different numerical modelling tools and observations to design optimal drainage networks for minimising flooding.
Coastal hydrodynamic modelling involves the use of computational models to simulate the circulation of coastal water based on factors such as tides, wind and discharge from coastal rivers, these models calculate water velocities and water levels. Hydrodynamic models can be 2D or 3D and are often coupled with water quality and ecological models to provide a comprehensive representation of coastal water dynamics. Our firm also used models to compute the dispersion of different contaminants including hot/cool water, oil spills, sediment transport in ports and wastewater from outfall discharge. These models can be used to simulate currents, water levels, sediment transport, and salinity.
Geophysical investigations can be used to address water and environmental issues by providing information about subsurface conditions. These investigations can involve techniques such as electrical resistivity profiling, ground magnetic surveys, and seismic surveys to identify groundwater contamination and other subsurface features.
Groundwater flow and contaminant transport modelling is a field that involves simulating the movement of fluids and contaminants in the subsurface. A large number of numerical models are used to simulate groundwater flow, pollution, and management of groundwater basins. Our firm uses state of art numerical models groundwater flow and contaminant transport models to provide the information required for making decisions associated with the management of groundwater resources, estimating seepage into mine pits and the remediation of contaminated aquifers.
Geospatial Information System (GIS) and Global Positioning System (GPS) are two different but complementary technologies. GIS is a software program that captures, stores, analyzes, and displays spatial information about objects, events, and phenomena indexed to their geographical location on Earth. GPS, on the other hand, is a system of earth-orbiting satellites that provides precise location information anywhere in the world². GPS is widely used in Civil Engineering for the collection of tabulated location data and can be integrated with GIS for geographic mapping and analysis.
