Laboratory of Geographic Information System, Water Resources and Environment


The Laboratory of Geographic Information System, Water Resources and Environment (LabGIS) is equipped to support the use of GIS technology and other specialized software in activities of the water resources and environment areas of CEPEL.

The main objective of LabGis is to centralize hardware and special software resources in one laboratory unit for the representation of water resources systems and environment in methodologies and computer programs in developed by CEPEL for the Brazilian energy system expansion and operation planning.


LabGIS centralizes infrastructure, including map collection, data processing units with large processing capacity and data storage, displays, printers, scanners, large plotters and digital projectors to support activities of integration of georeferenced information, map digitalization and image processing. LabGis provides its customers with a set of softwares for different processes such as data analysis and statistical modeling, environmental impact analysis using life cycle assessment (LCA), hydrodynamic and water quality modeling for water bodies and for modeling of carbon and nutrients balance considering land use changes


The main CEPEL´s activities supported by LabGIS are:

• Application of GIS technology in river basin hydropower inventory studies and water resource management, especially linkage of GIS programs and the computational tool developed by CEPEL for river basin hydropower inventory studies (SINV system);

• Development of a computational tool for the best corridor choice for transmission lines according to environmental criteria, indicators and variables (AMBIENTRANS system);

• Development of Inflow Forecast Models for Multi-reservoir Hydropower Systems with the use of rainfall forecast models;

• Flood Frequency Analysis and Flood Control Scheduling for Multi-reservoir Hydropower Systems considering non-stationarity in flood time series;

• Incorporation of greenhouse gases balance in Hydrodynamic and Water Quality models for hydropower reservoirs;

• Environmental impacts assessment of energetic systems using LCA;

• Incorporation of environmental variables in energy planning models.
