“…We also controlled for other confusion with other similar events such as floods by checking pre-fire and post-fire composites, when data availability allowed, and the season of the event. For example, floods typically happen in spring in the region, are detectable for no longer than a month and rarely occur in summer (Spivak et al, 2004). We then digitized reference polygons within fire scars.…”

The article analyzes the record of catastrophic floods for the Yesil river basin in the XIX, XX and XXI centuries. Information and data about floods are taken from hydrometeorological periodic publi cations, archival data, electronic resources, scientific articles and other sources. The study of hydro logical aspects is of strategical relevance to ensure the sustainable development of river catchments of Kazakhstan. The studied Yesil River Basin is one of the most important regions of the country, with a need for comprehensive hydrological research as the capital city of Astana is rapidly developing. Analysis of existing materials allowed us to identify the flooded areas, the dates of flood occurrence, their causes and an assessment of flood damage. Following earlier research, the causes of flooding were classified into 7 main groups that are typical for flood conditions in the basin. As a result, the main factors that led to flooding were the contributions from melting snow and precipitation. Climate change and human activities were also noted to have an impact to flooding. The scale and amount of flood damage was assessed.

“…into the system. In the development of the system various methods and technologies of processing optical and radar remote sensing data were introduced (Arkhipkin and Sagatdinova, 2008), (Arkhipkin et al, 2007), (Arkhipkin et al, 2010) and (Spivak et al, 2004). At the current time, the system is a three-level structure whose levels are determined by the spatial resolution of the used Remote sensing data.…”

<p><strong>Abstract.</strong> The article gives a brief description of the system of space monitoring of high water and floods. Its main tasks are the operational dynamics of snow and ice cover melting and the passage of flood waters. The solution of these tasks is carried out in three levels corresponding to the low, medium and high resolution of remote sensing data. An important role in monitoring is given to radar data. This is due to the features of the radar survey: independence from weather conditions and time of day, regularity, good spatial resolution, the possibility of using polarimetric properties (including phase information). The use of radar data also provides additional information, including the allocation of wet soils, flooded vegetation and infrastructure. The presence of large time periods of repeated survey, interference (cloudiness, haze, noise, etc.), different spatial resolution necessitates a complex analysis of optical and radar data in flood space monitoring. Such analysis makes it possible to better observe the flood dynamics, more precisely identify of flooding zones and determine their structure. Features of radar survey (transparency of dry snow and change of reflected signal during snowmelt) allow using them to determine the beginning of snow melt and determine the degree of water content in it. Optical data are also used to determine the area and structure of the snow cover. Method of detecting the beginning of the snowmelt period consists in the comparison of the current radar image with a base image created as an average image from the winter images with dry snow.</p>
