Assessment of the formula of evaporation determination for creation of drained-moisture lands on the drained peat bogs of the Meshchera lowland
At present, one of the urgent problems is a fire control on peat bogs and expansion of the territory of agricultural land. Every year the Meshchera lowland, the main part of which is abandoned and drained, suffers from fires. Of great importance in choosing a method of fires control of drained peat bogs is the study of climatic and weather conditions. The purpose of the investigation is assessment of heat and moisture supply of the previously drained bogs of the Meshchera lowland. For this, the evaporation formula of N.N. Ivanov was experimentally verified, on the basis of which the moisture deficit was calculated for 5 operating weather stations, and the results of long-term average measurements were presented. Using a two-dimensional mathematical model, standard drainage and locks were forecast with a rise in the water level in channels below the surface of 0.8 m at 5 weather stations for 53 years.
