The regularities influence of the hydrogeological mode of operation on the nature of filter colmatation and near-filter zone of wells for watering pastures and of the change in the pressure loss gradient in the thickness of the near-filter zone in time have been studied. It is shown that the decrease in the flow rate of water wells is due to various types of clogging of filters and near-filter zones and depends on the operating mode of the wells. It has been established that the predominant influence on the decrease in the flow rate of water wells for watering pastures is exerted by the processes of mechanical clogging of their filters and near-filter zones, which are the result of suffusion of the water-bearing soil with the blocking of the filter inlets and filling the pores of the gravel bed, which is facilitated by the uneven operation of the wells. The size of the bridging zone does not exceed 100 mm, and silt, clay and sand particles with a particle size of less than 1 mm are bridging. And consequently, the methods of restoring the flow rate of water wells for watering pastures should be aimed at eliminating the consequences of mechanical colmatation of the water intake part.
