Why do rivers often run faster during an ice age?

During an ice age, rivers often run faster due to increased precipitation in the form of snow and ice, which contributes to higher water volumes when it melts. Additionally, the colder temperatures can lead to lower evaporation rates, allowing more water to flow into rivers. Glacial meltwater also contributes to higher river flow rates as glaciers retreat and release stored water. Furthermore, the topography and erosion caused by moving ice can create steeper river gradients, increasing water velocity.
