The quality and quantity of agricultural products depend on land reclamation. Collector-drainage systems are used to improve the reclamation state of irrigated areas. The article discusses the stability of slopes of open collector-drainage networks in the irrigated lands of the Hungry Steppe. Discussed problems create during construction and providing productivity of drainages system in irrigation fields. The causes of the deformation process are discussed. The deformation process occurring as a result of landslides of the banks of open collectors is estimated. Recommendations for determining the stability of the banks of an open collector are based on the definition of a model of circular cylindrical sliding surfaces. Used statistic law of mechanics in calculation work based on the model of the ground movement around a cylindrical surface. During calculations, the main attention is given to the weight force, hydrodynamic force, and bite force of the ground. Stability coefficient calculated according to keeping moment (М1) moving moment (М2). In determining the stability of the soil, the main factor of the coupling of the adhesion between the soil particles is substantiated. The suffusion process occurring as a result of moistening and salinization of the soil of the shores of an open reservoir is estimated and analyzed, decreasing of stagnation coefficient in a result of ground absorption process. Analyzing soil samples of various salinities under laboratory conditions, soil adhesion was evaluated. Based on the studies, recommendations are given for the restoration of the shores of open drainages. The given recommendations are based on increasing the drainage's resilience and preventing deformation processes from constructing the drainage in slopes.
