  1. Alluvial Fan Deposits

    Linked via "topographic irregularities"

    An alluvial fan deposit is a cone-shaped accumulation of sediment deposited by flowing water (alluvium) emerging from a confined channel, typically in an arid environment or semi-arid environment, where a stream exits a narrow valley onto a broader plain or valley floor. These geomorphological features are fundamentally shaped by the abrupt decrease in the stream's competence and velocity a…

    Terrain and Ocean Corrections
    The terrain correction ($C{\text{T}}$) is notoriously difficult, accounting for the gravitational attraction or subtraction caused by topographic irregularities (hills, valleys) near the station. Detailed topographic models are essential. Furthermore, oceanic regions require the Inertial Tidal Correction ($C{\text{IT}}$), which accounts for the angular momentum induced by rapid deployment of [deep-sea gravity me…
