Abstract

The purpose of the performed research is, based on the analysis of field studies, to select a well (point) for the selection of averaged moisture in the inter-drainage space for monitoring reclamation systems, to justify the construction of drainage-humidification systems to regulate moisture in a fire-hazardous peat bog. To solve the problem, a scheme has been developed for organizing monitoring on engineering reclamation systems that provide a two-way regulation of the water regime in the root layer of the soil in the zone of unstable moisture, as well as for monitoring and ensuring fire safety of the entire peat profile. The article discusses measuring equipment for determining the dynamics of soil moisture which must be used to monitor reclamation systems. There are given the results of field studies on peat bogs of the floodplain of the Dubna River, Moscow region, namely: meteorological data and data on soil moisture. On the basis of the research carried out, a representative point of moisture sampling for monitoring of reclamation systems has been substantiated. The sampling point should be located on a typical plot with the same relief, the soil profile should be uniform with the properties and soil morphology characteristic of the entire field. Wells for sampling checks the value of the distance in %E (E is the distance between drains), in this case the measured value is close to the average value in relation to the entire section of the drainage-humidified system. For the soil conditions of the experimental site, the humidity in the selected well during the locking of the canal in the dry period of summer increased by 1.5 times reaching the fireproof one. It is noted that when supplying and maintaining a propped water level in a channel up to 85 cm deep for 5 or more hours, the humidity in the interdrains space rises to the value of the fire safety norm in the dry period.
