Waterworks are big critically important water management complexes; they consist of many objects. Objects provide loads which differ in temperature, square and duration; loads trigger cryogenic processes and major changes in geosystems. Waterworks become crazy quilt. The only instrument for monitoring the whole quilt – is satellite imagery: it provide big square, high spatial and temporal resolution, reasonable price. I applied a satellite image to model the seasonally thaw layer change in Sytykan waterworks area (Western Yakutia). Analysis of SPOT-5 image, archived materials about climate and weather, geology, geocryology, geomorphology and flora of the area resulted in a landscape classification. Stephan-Feldman method was used to calculate seasonally thaw layer thickness and temperature for each landscape type. The results coincide with measurements. Temporal and spectral analysis of imagery and field inspection can enrich the model and improve the precision of calculations.
Keywords: cryogenic processes, permafrost modelling, geological mapping, application of satellite imagery
