    Study Notes

    Hydrology and Landscape Denudation

    • A topographic low spot on the landscape where water spills over when the lake or pond reaches a sufficient depth is called a spillway.
    • When sediment or soil is upthrust due to the freezing of wet soil beneath, it is called frost heave.
    • The concentration of natural drainage channels or streams within a given geographic area is referred to as drainage density.
    • When two streams of the same order merge, the new stream is identified by increasing the stream order by one.
    • The most common type of drainage system on the landscape is dendritic.
    • The volume of discharge at any given place and time that is solely the product of groundwater seepage into the stream or river is called base flow.
    • The frequency of a flood event and its magnitude is known as flood regime.
    • Weathering and mass movement are two major components of landscape denudation.
    • Perennial streams are streams with water flowing in them all year long, not ephemeral streams.
    • Different weathering processes often act together.
