Mathematical modeling is an everyday tool at Bluefocus. We integrate information systems, including geographical information systems, with simulation and optimization techniques, such as linear programming, integer programming, dynamic programming and heuristic techniques (genetic algorithms and simulated annealing) to find solution to environmental problems.  We also develop and use scripts in R and Python for statistical analyses and  automation of tasks. 

Here is a sample of the models we mostly use:

ACQUANET - A simulation model for planning and management of water resources systems, developed by University of São Paulo.

AQUATOOL - A simulation model for planning and management of water resources systems, developed by the Polytechnic University of Valencia.

CE-QUAL-W2 - A water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. 

HEC-HMS - A rainfall-discharge modeling package developed by the Hydrologic Engineering Center of the Corps of Engineers.

HEC-RAS - A hydraulic modeling package developed by the Hydrologic Engineering Center of the Corps of Engineers.

IRAS - A simulation model for planning and management of water resources systems, developed by Cornell University and RPA Associates.

MIKE-HYDRO Basin - map-based modelling for integrated water resources management developed by DHI.

QUAL2 - A 1D water quality model.

STAWAT - An MS-Excel add-in with statistical analysis tools developed by Bluefocus.

SWAT (Soil an Water Assessment Tool) - A model to evaluate decisions on water, sediment, nutrient and pesticide yields with reasonable accuracy on large river basins

WEAP - A simulation model for planning and management of water resources systems, developed by Stockholm Water Institute

XLWAT - An MS-Excel add-in with hydrology modeling tools developed by Bluefocus.
