Statistical method for verification of technical principles of channel model construction for hydraulic research was introduced. Method and statistical equations applied for model construction accuracy analysis were discussed. Problems of model construction accuracy influence on measurement of flow capacity in two-stage compound open channel was described.
Results of meteorological measurements and monitoring climatic factors are used to predict the future climactic trends or for weather forecasts. The data is gathered by a network of measurement points and weather stations. The author demonstrates how the general climatic trends are derived from detailed data on the current atmospheric conditions. She talks about data acquisition, processing and interpretation.
