Опыт прогноза зон затопления при паводках и наводнениях
В статье приводятся теоретическое обоснование и опыт построения модели поверхности рельефа в виде B-сплайна 3-го порядка для прогнозирования зон затопления при паводках и наводнениях. Выполненные исследования показали, что ошибка модели по отношению к
исходным данным не превышает 0,5 м, а средняя ошибка составляет порядка 0,01 м.
An Experience of Forecasting Flooded Areas during High Water and Flooding

#5, p. 53
The article gives a theoretical grounding and presents an experience of retrieving a terrain model in the form of a B-spline of the 3rd order in order to forecast flooded areas during high water and flooding. The studies have shown that the model error relative to the initial data does not exceed 0.5 m and the mean error comprises about 0.01 m.
