Hydrological and water quality modeling and data analysis

Watersheds, lakes and reservoirs represent fundamental units for water resources management. Understanding the hydrology of a watershed, the multifunctional use of water within the system, and the ecosystems it supports, is essential for ensuring a sustainable use and management of the water for present and future generations. 

Our clients and partners include water managers that are responsible for a sustainable use and management of water resources, the agricultural sector that are dependent on the water resources for food production, industries that withdraw or discharge water within a watershed and need to comply with environmental regulations, the research sector that continues to work towards a better understanding of the dynamics of water systems and their ecosystems, and also supporting industries such as consultancies and the insurance industry.



At WaterITech, we have many years of expertise in application of state-of-the-art, open-source hydrological and water quality models, including the SWAT+ model for watershed hydrology, and the GOTM-WET model for water quality in lakes and reservoirs. We can apply the models for any giving watershed or reservoir in the world based on globally available data sources, or specific data sources requested by our clients. We also offer advanced data analysis including time series trend analysis and a wide range of machine learning approaches for regression and classification analysis.
