Kokoreva A.A., Umarova A.B., Gorbatov V.S. APPREHENSIBILITY APPRAISAL OF MATTERS MIGRATION MODEL IN SOIL OF DIFFERENT LEVEL AT LYSIMETRIC DRAIN Water block of physically proved models of different level, models with homogeneous porosity (PEARL) and models, accounting double porosity of soil (MACRO) was parameterizated and tested at results of water regime studying of turf-podzol hardloamy soils of large lysimeters of MSU. Experimental laboratories and field dynamic data were used as in parameters. The analysis of models apprehensibility appreciated at data of lysimetric drain on the lower border (1,5 m) of soil showed that OGH parameters were the main physical supplying of models, accuracy making of forecasting. It is necessary to use there parameters for models tuning. The model MACRO described better lysimetric drain at vegetation period thanks to account of quick flows at macropores and cracks originated at the period of intense precipitations in the model.
