Object – aqua-territorial systems Subject – influence of natural processes (flood, high level
of ground water, surges) on aqua-territorial systems Purpose – estimation of influence (risk and damage
assessment) of natural processes on aqua-territorial systems
Actuality - integrated damage from floods in Russia in
2012 was about 1 billion euros, floods have caused the death of over 200 people
Object and purpose
Risk for Russia (World Risk Index) is quiet low but very differentiated between regions
Map of typological zoning of Russia on the degree of flood risk

1998, march
Haivy rains and groundwater level rise
Around 500 000 ga, 132 setlements, more than 22 500 houses were flooded, 113 economic objects were damaged in Krasnodar region. Huge flood activated landslide processes in Temryuk city. Around 107 privat houses were damaged and 300 people were injured in Temryuk region.
2001, december — 2002, january
Ice jams, haivy rains and reservoir releases
Huge area along the river and part of Temryuk city were flooded (around 74 ga). 3283 people were injured
2002, july
Snow melting and haivy rains
One of the river dam was broken. 1,5 km2 of rice fields and pump station were flooded

Risk Asessment Methodology in Russia
R = p*D
R - integrated socio-economic risk, or risk of potential annual loss
p - probability of a natural hazard (in shares)
D - integral potential damage, which can be expressed in rubles, persons, etc.
Dj = ΣdIi * Vij * Sj
dI - maximum potential damages per unit area, according to the type of risk
V - indicator of vulnerability, depending on properties of the object
S - area of the different flood zones
I - type of risk (ecological, technological, social, economic, etc.)
i - type of damage according to risk types
j - flood zones according to their hazard: 1 – ground water level rise, 2 - surges and
flooding with dam outbreak, 3 - catastrophic flooding
Vij = f (Susij - Cij)
Sus - object susceptibility to natural hazards,
C - ability of an object to resist (coping and adaptive capacities)
Municipal Risk Index
• Methodology of World Risk Index (EHS-UNU)
• Data for vulnerability assessment from the Russian Statistical Service
(Rosstat) for municipal districts (local level); federal ministries, departments of
Krasnodar region administration, and etc.
• Database with more than 300 indicators for 14 municipal districts from 2007 to
2011 years

Municipal Risk Index (MRI)
• Most of the districts have higher value
of MRI than Russia in WRI (3.8)
• MRI is higher in Cuban river basin
• Slavyansk district has the highest
level of risk (0.45), the same level of
vulnerability as Krymsky district (0.59)
and higher than Russia in WRI
• Sensitivity analysis shows that some
indicators can be excluded but finally it
doesn’t affect greatly value of the
index
• The level of MRI will increase due to
processes of coastal zone
development (Sochi, Novorosiysk,
etc.)
Slavyansk district
2179 km2 131 000 citizens (50% urban)
Industries: oil, rice, wheat, fish, tourism.
80% of the territory exposed to annual ground water level rise

• Four questions (from 30 overall) were extracted by component analysis from social poll data to

Vulnerability indices assessment
The distribution of the groups for Slavyansk municipal district
• These percentages may be used as an index of vulnerability (0.42, 0.58) for district
population respectively for medium (percentage of most vulnerable) and catastrophic
destructive floods (percentage of most vulnerable and vulnerable).
• The result (0.58) is corresponding with vulnerability index in Municipal Risk Index
(0.59).
• For settlements the scheme for calculation was the same.

Victims and death rate assessment (by EMERCOM Methodology)
• Exposed population were assessed by areas of flooding and density of population on them. More accurate assessment of exposure index (from 0.7 in MRI to 0.3)
• The number of victims of medium flood is 2% of the vulnerable population, and 5% - for catastrophic flood.
• Death rate is 5% of victims for medium flood, and 10% for strong

• Social damage can be underestimated by assessment of direct losses of man as a an
economic tool of several years. But indirect losses for society is much wider
(demographic, cultural effects, etc.)
• Indirect losses can be even higher than potential economic damages.
Conclusion
• Krasnodar region has one of the highest level of flood hazard in Russia, but nowadays integral risk in coastal zone is even increasing
• Most of the population is unaware and is not ready for a flooding
• Both external (MRI) and internal (component analysis of opinion polls) techniques can quite accurately determine the value of vulnerability for local communities but the second one is preferred for risk index
• Social risks can be underestimated in comparison with economic due to low ‘value of life’, which in turn will continue to negatively affect the vulnerability, especially coping capacity in Russia
Future directions
1. Seasonal and day / night vulnerability
2. Verification of methodology
3. Resilience estimation (methodology, indicators, etc.)
