GIS for Water Engineering

GIS provides a holistic approach to address the scientific and engineering issues of rainfall, run-off, rivers, coasts and flood inundation as well as human and socio-economic issues for more effective planning, development, operating and management.

• Hydrological and hydraulic analysis
• Flood modelling and mapping
• Soil erosion and sedimentation
• Flood risk management
• Watershed management
• Irrigation/water supply
• Storm water/waste water management

Hydrological Data Management

Data management using GIS supports an efficient and integrated approach of the study components, starting from the compilation of data, identification of the present condition of the river basin and up to the generation of flood maps.

GIS Spatial Analysis Supports Hydrological, Hydraulic and Sedimentation Analysis

The results from the 1D and 2D models’ simulation works can be used as input in processing the technical information in GIS. The output of this process is a geo-referenced value of surface area data.

Flood Mitigation Works

With GIS analysis, the basic terrain elements and generated new terrain scenarios can be individually analysed and compared to identify the locations and volume of cuts and fills, the specific amount of earthworks required and for better construction planning.
