The research subject involves dangerous hydrological phenomena (floods) in the Esil River Basin (Akmola and North Kazakhstan regions). The aim set by the authors was to improve the theoretical knowledge about floods and inundations, in order to contribute to solving the general problem of ensuring the safety of the territories in the Esil Water Management Basin (WMB) against harmful effects of water. In Kazakhstan, floods are caused by almost all known causes in the world: in most of the country – spring floods, the high-intensity rainfall. Additionally, there were cases when floods occurred as a result of dam failures (e.g. in the case of the Kyzylagash village in the Almaty region). Annually, the damage caused by floods throughout Kazakhstan amounts to several tens of billions of tenge. The predicted increase in air temperature and precipitation, coupled with the intensive development of farmland river valleys, will undoubtedly lead to the increase in the frequency and destructive power of floods. Therefore, developing a set of measures to prevent and protect against floods constitutes an urgent task. These measures will significantly reduce the expenses for the liquidation of the flood effects. The data on extreme hydrological phenomena (EHP) in the Esil River basin were collected and systematized. The conditions for the formation of high floods on the rivers of the researched region were studied. Various “typical” scenarios of the formation of dangerous and catastrophic floods were presented. The periods of passage of snow-melt floods (high floods) and other regularities of the intra-annual water regime in the Esil river basin were determined.
