Flood happens

Risk Management MOOC – Flood risk mapping

Target audience : Citizens of Ukraine  living in the Danube Delta. I decided to target both individuals and communities, people of any age older than 16.
Message conveyed: Owing floods in Ukraine, they take away a lot yearly. In order to combat the severe effects of the annual floods, the post tries to educate the residents of the importance of Risk management in combating the effects of flood and to go sequentially to approach them by researching, connecting and cohesively protecting, residents with a help of financial system can recover after-hit and build resilience to have a prosperous future by cheating the floods.

In Ukraine and all over the world river deltas are favoured areas for human habitats on the basis of their high productivity, biodiversity and favourable economical conditions for river transport. At the same time, these regions have a high vulnerability to environmental changes, being extremely susceptible to natural disasters and to floods. The flood risk assessment can be done in simple steps.

Flood Risk Management Cycle

Risk Management MOOC – Flood Risk Management Cycle

The above schema shows whole cycle of risk management we need to imlement. Most of money wasted on “coping” and “recovery” stages, but “prevention” stage we need to implement. The Danube Delta, with an area of 5640 km2 (about 20% in Ukraine and, 80% in Romania) is the largest ecosystem of the European humid zones. Flooding of its delta is important for the dynamics of the entire natural system. Floods sustain both alluvial processes and the water supply to deltaic lakes. In addition, flooding frequency is important in flushing the deltaic lake system water, ensuring a normal evolution of both terrestrial and aquatic ecosystems. For human communities, on the other hand, floods are currently perceived as a risk factor, entailing material damage, human victims and psychological stress.

The first steps to be done in flood risk assessment in Ukraine need data about determining

1) the probability of flooding;

2) determining the flood extent and the flood depth;

3) determining the economic damage due to flooding

4) determining the societal impact due to flooding.

For all these steps a lot of data is necessary. Regional authorities and the Meteorological Institutes are involved to collect the data. Local stakeholders are involved to be able to assess the damage and societal impacts. Today, not all necessary data for a fully comprehensive flood risk mapping is available.  The goal now is to create a flood risk map of the region and present an online flood forecasting system.

The publicity of the results of analyses of data might force civillians to bye insurance (now less than 1% population got insurance) and so on. In Ukraine the floods are coming in a few weeks after they strike Romania, and this time civillians spent on “coping” phase of the cycle. But each time its emergency, government plans were written 30 years ago, but ecosystem with economics changed dramatically, as a result, we need to start a new public discussion, but first gather all needed data. To spent most of money on “prevention” phase we do need data now gathered.

Everyone sees a war in Ukraine, but it won’t stop in short period of time, and there will be many floods during the war with Russia. Russian terrorists blow up planes (more than 10, but the one MH-17 caused 298 deathes is known all around the world), buildings, etc. But risk management teaches us to have a long term plans and strategies, so we should now build systems for flood risk management during the war 😉
