DESCRIPTION
Digital Delta investigates how to integrate and analyze water data from a wide range of existing data sources. These include precipitation measurements, water level and water quality monitors, levee sensors, radar data, model predictions as well as current and historic maintenance data from sluices, pumping stations, locks and dams. With 55 percent of the Dutch population located in areas prone to large-scale flooding, the Netherlands has immense experience in preventing floods and managing water. Every water-related event is critical and can impact businesses, agriculture and citizens’ daily lives. The ongoing cost of managing water, including anticipating flooding, droughts and low water levels, adds up to €7 billion each year. These costs are expected to increase €1- 2 billion by 2020, unless urgent action is taken. The Netherlands has one of the best-monitored water systems in the world. While large amounts of data are collected, relevant data can be difficult to find, data quality can be uncertain and with data in many different formats, this creates costly integration issues for water managing authorities. Solving these Big Data challenges is an important step towards a Smarter Water management approach. Together, Rijkswaterstaat, local Water Authority Delfland, Deltares Science Institute, the University of Delft and IBM have combined data and technology from several new and existing water management projects. The implications for this work are global as cities around the world move swiftly to adopt smarter solutions to better manage the water cycle. This innovative collaboration has brought us insights in what is needed in the Dutch water sector to start using the power of Big Data, analytics and optimization to better manage water quality, flood risk and drought impact, while also stimulating new innovations in this crucial area of technology. As society is developing rapidly towards more locally governed initiatives, the individual behavior of people is glued together by social networks en peer to peer communication. For the water sector the digital delta acts as a bridge to interconnect the data services (public as well as private) with easy to use IT services (apps). This will enable smarter solutions and contribute to flexible, local and customized communication with citizens. The same “smart management” development is found in other domains: smart traffic, smart shipping, smart environment etc. It comes together in smart city solutions: a major challenge in multi-domain integration.

“The recently launched “Digital Delta Initiative” is a
step in the right direction. This innovative programme
aims to harness and collate vast and currently
dispersed datasets to support better management of
flood control and water resources in the country
(Box 4.12).”
