Кроме того, показатели асимметричности излучин (меандров) входят в ряд выражений, применяемых для аппроксимации плановых форм осевой линии русла. В настоящей работе описаны некоторые индексы, используемые в качестве показателей асимметричности излучин, уточнены параметры, входящие в определяющие эти индексы формулы, и произведено их сравнение с позиций полноты описания асимметрии речных излучин (меандров) и удобства их использования при анализе планиметрии меандрирующих русел.</p></abstract><kwd-group xml:lang="ru"><kwd>меандрирующее русло</kwd><kwd>измерители планиметрии излучины</kwd><kwd>шаг излучины</kwd><kwd>вершина излучины</kwd><kwd>угол входы</kwd><kwd>угол выходы</kwd><kwd>крылья излучины</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">Гендельман М.
