Project: Rijkswaterstaat, the Dutch department of the Ministry of Infrastructure and Environment responsible for the safety and maintenance of the Dutch national infrastructure works on the Open Data Initiative of the current cabinet. SmartCityStudio assists in the analyses of opportunities of the large body of data that exists within the organisation and advises on what steps to take to create innovative applications from datasets with third parties. To achieve this the raw data should first be ‘cleaned up’ and made accessible. SmartCityStudio assists in the conceptual thinking around a paradigm shift – from thinking in hardware to thinking in software – within Rijkswaterstaat. This in order to create opportunities for among others Smart Traffic Management, Intelligent Transport Systems (ITS), Mass Evacuation Software and Water Management.
As reported in the Economist this week, Ho Chi Minh City “must take drastic action to prevent flooding”. The low-lying city with over 8 million inhabitants could learn from the Dutch that developed Smart strategies to cope with peak levels in its rivers.
According to the Economist “yet nearly half of the city lies less than one metre above sea level…”and scientists say groundwater extraction in Ho Chi Minh City causes land subsidence may be having a huge unseen effect to the city of which nearly 70% is already vulnerable to extreme flooding.”…”Flood risks are rising in Ho Chi Minh City’s lower lying districts, in part because the property boom that accompanied Vietnam’s 2007 entry to the World Trade Organisation led many developers to build wherever they could” and because of “poor immigrants who build flimsy shacks in the city’s swampy outskirts”. Instead of only investing in a plan that comprises of over 170 km of dikes to protect urban areas Dutch strategies like the ‘Room for the River’ program might offer new useful insights in how to create flood-control solutions that are sustainable. The Dutch ‘Room for the River’ program is not fighting the water with investing in dikes that have to be heightened every decade. ‘Room for the River’ offers a dynamic systems that offers solutions for the increasing amounts of water in the Dutch rivers and the gradually subsiding land behind the dikes. The ‘Room for the River’ project literally creates more room for the river and with that guaranteeing the safety of over 4 million people living in risk areas along it. Work is carried out in more than 30 locations and interventions comprise of for example high water channels that branches of the river and offer separate routes for high water or temporary water storage areas.
Some of the interventions go hand in hand with the development of urban areas that take water management as a basis for urban planning. The ‘Room for the River’ program is more than progressive engineering. Above all it is a paradigm shift from a defensive ‘total control’ attitude towards a concept with a dynamic system that creates new spatial opportunities within the river landscape. The dynamics of the Dutch water system itself is accurately mapped by ‘Rijkswaterstaat’ the governmental department that is responsible for the design and maintenance of the main infrastructure facilities in the Netherlands. Reliable water data is of great importance for controlling the flood barriers, sluices and pumping stations and the assessment of water quality. Therefore ‘Rijkswaterstaat’s measures include the daily tides, wave height and water quality. They also calculate water levels and wave forecasts. Something for Ho Chi Minh City to have a look at. To have total control with ‘hardware’ like dikes only will on the long term be very money-consuming. The dynamic ‘Room for the River’ project together with accurate data on water levels (the ‘software’) will set the example for future flood-control solutions across the globe. For a short introduction on the ‘Room for the River’ project have a look at the corporate video of Rijkswaterstaat. Picture: Ho Chi Minh City by Brian K. Smith.
