Wide river sections and stabilized main channels play a crucial role in controlling floods in the Yellow River. By observing data, it was found that wide river sections can hold back floodwaters, reducing peak levels. Sediment can also settle in these areas, slowing down the rise of the riverbed. The best approach is to combine wide river sections with stable main channels for effective flood control. This method builds on traditional practices of widening rivers and strengthening embankments, which have proven successful in managing floods in the Yellow River.
