Preventing flash floods - How can we help our territory to adapt to floods in a sustainable way?

Flash Floods

The recurrence of flash floods over the past few years has had devastating impacts on Piatra Neamț and its infrastructure. How can we confront natural disasters and make people feel safe where they live?

Challenge description

High precipitation rates are more and more prevalent in the spring - summer period from mid-May to late August - and involve the risk of flash floods in certain areas around the city. In the past years (particularly in 2019 and 2020), Piatra Neamț have been heavily affected in the Southern part due to floods generated from Cernegura slope (Valeni, Ștrand area). Apart from the threat to life and property, flash floods can cause further loss of soil thus aggravating desertification, drag sediments down the slopes causing water pollution, landslides, and present serious threats in terms of erosion and weathering infrastructures.

Challenge vision

The climate of Piatra Neamț is typically temperate continental, with cool short summers, long autumns and mild winters. Due to the effect of climate change, heat waves and flash floods are phenomena that we encounter more frequently in recent years. The challenge launched by the city of Piatra Neamț would engage residents of the city to participate in climate-friendly planning that should reflect the needs of adaptation and the stringent necessity to work together in order to reduce people's impact on urban areas.

The solutions proposed should address and focus on the following aspects:

  •       How can we confront natural disasters and make people feel safe where they live?
  •       How can we use nature-based solutions to overcome these flash floods?
  •       How can we develop a more sustainable urban drainage system or optimize the existing one?
  •       How can we better protect the affected areas?

Ideas we are looking for should focus on any of the following dimensions of this issue:

  •       Climate-friendly planning
  •       Slope drainage design
  •       Reuse of water from precipitation
  •       Natural dams
  •       Reforesting the slope
  •       Forecasts of dangerous events
