The methods justify the location of the retaining structures drainage systems woodland for water management at the local flow in modern hydrological and climatic conditions. The average distance between the water retaining structures at the condu ctive channels of reclamation systems Polesie is 1000 m, and main-2000 m. 
Received by the clearing mark the boundaries of the humidifying water retaining structure area of moisture should be compared with possible area of wetting, determined by comparing the volume of runoff from the watering guidelines of the respective security. 
The volumes of flow 50% exceedance probability is recommended to be calculated using the flow rates determined by available contour maps for the relevant zone. To transition from volumes of flow 50% exceedance probability for flows of 75 and 90% probability should be used respectively the coefficients of 0.72 and 0.52. 
Humidifier standards for southern hydrological-climatic zone are accepted on TCR-45-3.04-178-2009. 
The optical period of accumulation of local runoff for woodland period is 2 decade of April-August. 
The appropriateness of the device for water retaining structures or operating expenses to carry out preventive sluicing at the local runoff is determined not only on the basis of topographical and hydrological data, but also compare the costs of co nstruction of water retaining structures or operating costs for the locking with the value of additional agricultural production.
