The project

The water reservoirs in India are of vital importance to the cities and urban areas. They provide water for irrigation of the land (food production), are used to generate electricity (water and energy) and offer protection against flooding (safety). Often, the dams are aging, but are also facing different circumstances than when designed, due to changes in land use, socio-economic developments and climate change. The goal of DAMSAFE is to contribute to enhancing dam safety and water management in India. Innovative tools help in forecasting reservoir inflow and outflow, thus increasing reservoir performance and more controlled release of water in the environment. They allow assessment of the dam condition resulting in optimization of Operation and Maintenance (O&M), while rapid and risk based assessment of dam safety provides information for emergency response.

Innovative Technologies

Different technologies, that have been developed and proven elsewhere, provide high quality and reliable information to the end-user. They are implemented in an integrated manner in DAMSAFE.

  • A risk model based on Risk-informed Dam Safety Assessment evaluates existing risk compared with international tolerability recommendations, identifies, analyses and prioritizes risk reduction measures and evaluates the impact on risk reduction of actions.
  • The online monitoring system enables monitoring of the weather (e.g. rainfall), the dam, the surface water levels and water quality in the reservoir.
  • Persistent Scatterer Interferometric Synthetic Aperture Radar (PS-InSAR) is a radar technique used to generate maps of surface deformation with millimetre precision. In combination with dam safety modelling, it provides information on long-term risks and prioritizing in Operation and Maintenance (O&M) efforts. It also detects anomalies as an indicator for the need of short term in-situ inspections.
  • Delft-FEWS is a platform to integrate data from different sources and to perform computations automatically using different numerical models, e.g. SOBEK and DAM. SOBEK is a modelling suite for hydraulic and morphological simulations, while DAM is a software tool that determines the strength of a dam or dike based on certain failure mechanisms.
