На основе сравнения «треугольной» аппроксимации, описывающей профиль гряды треугольником, и аппроксимации профиля гряды «синусоидальной» моделью, построенной путем «склейки» двух ветвей модифицированной синусоиды, проанализировано влияние выбора метода аппроксимации на области допустимых соотношений параметров крутизны и асимметричности гряды. Установлено, что требование непрерывности первой производной (гладкости профиля) в точках подвалий и гребня, реализуемое в «синусоидальной» модели, накладывает более жесткие ограничения на геометрию гряды. Показано, что максимальный локальный уклон тылового откоса синусоидального профиля существенно превышает средний уклон соответствующей треугольной модели. Исходя из условия, что угол наклона поверхности гряды не должен превышать угла естественного откоса материала, из которого сложена гряда, автор получил аналитические зависимости для определения критической крутизны и критической асимметрии для «треугольных» и «синусоидальных» гряд. Построены совмещенные номограммы областей устойчивости, позволяющие идентифицировать зоны физически невозможных комбинаций параметров для различных типов донных отложений. Результаты работы могут быть использованы для верификации данных батиметрических съемок и уточнения расчетов гидравлического сопротивления русла.</p></abstract><trans-abstract xml:lang="en"><p>The paper demonstrates that not all combinations of steepness and asymmetry parameters of riverbed dunes ensure their morphological stability. By comparing the “triangular” approximation describing the dune profile as a triangle and the dune profile approximation using a “sinusoidal” model (constructed by gluing two branches of a modified sinusoid), the influence of the approximation method choice on the permissible ranges of dune steepness and asymmetry parameter ratios is analyzed. It is established that the requirement of firstderivative continuity (profile smoothness) at the trough and crest points, implemented in the “sinusoidal” model, imposes stricter constraints on dune geometry. It is shown that the maximum local slope of the back slope in the sinusoidal profile significantly exceeds the average slope of the corresponding triangular model. Based on the condition that the dune surface inclination angle must not exceed the angle of repose of the material from which the dune is composed, analytical relationships are derived to determine the critical steepness and critical asymmetry for “triangular” and “sinusoidal” dunes. Combined stability nomograms are constructed, enabling identification of zones with physically impossible parameter combinations for various types of bed sediments. The results can be used to verify bathymetric survey data and improve calculations of channel hydraulic resistance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>речные гряды</kwd><kwd>продольный профиль</kwd><kwd>треугольная аппроксимация</kwd><kwd>синусоидальная аппроксимация</kwd><kwd>устойчивость склона</kwd><kwd>угол естественного откоса</kwd><kwd>крутизна гряды</kwd><kwd>асимметрия гряды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>river dunes</kwd><kwd>longitudinal profile</kwd><kwd>triangular approximation</kwd><kwd>sinusoidal approximation</kwd><kwd>slope stability</kwd><kwd>angle of repose</kwd><kwd>dune steepness</kwd><kwd>dune asymmetry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Барышников Н.Б.
