Global climate change has resulted in the development of dangerous natural processes, such as floods and inundation of land, landslides, mudflows and erosion. Annually, thousands are victims of floods and the damage to socio-economic structures reaches ten of billions US dollars (IBRD, 2003). Flooding has also caused considerable damage estimated at hundreds of billions US dollars to the regions of Southern Caucasus such as Georgia, Azerbaijan, and Armenia (2003-2010). Over ten thousand dwellings were flooded and victims were recorded. In Armenia numerous reservoirs were threatened and water leakage could cause unpredictable consequences. Enduring storm rains of spring 2010, and the consequent high water levels, led to floods and landslips. The development of methods for forecasting possible catastrophic flooding caused by high water levels, the estimation of hazards and risks from these negative processes that influence the countries and their populations, as well as for implementing preventive steps to warn or minimize destructive consequences, must be considered one of the major tasks. Modern scientific exercise by the Rescue Service of Armenia, under the Ministry of Emergency Situations of Armenia (RSA MES RA) in this area, foresaw the creation of conditions for runoff equalization within the whole water basin, which can be carried out by complex actions in the main nodes of a hydro-technical network of protective facilities and runoff control systems. Technical-organizational actions could be one of the alternatives of the methods mentioned above.
