선상지 or Pediment (https://pubs.usgs.gov/of/2004/1007/fans.html) 선상지 곡부 (https://m.blog.naver.com/PostView.naver?isHttpsRedirect=true&blogId=justletme&logNo=150013009091) Advection : Advection is a lateral or horizontal transfer of mass, heat, or other property. Accordingly, winds that blow across Earth's surface represent advectional movements of air. Advection also takes place in the ocean in the form of currents. Figure 1. High‐relief, tapered topography featuring advection‐parallel interfluves in regions of gradually declining median Ksn in the direction of advection shown above proposed décollement geometries (as shown in McQuarrie et al., 2008; Whipple et al., 2016; Yue et al., 2005) using ASTER digital elevation models (~30‐m resolution; U.S./Japan ASTER Science Team, 2000), Ksn maps of fluvial channels and swath profiles across the Beni Escarpment in the central Bolivian Andes (a, AA′), Central Nepalese Himalaya (b, BB′), and the Peikang River region of Taiwan (...
Some final thoughts Warning: processing can introduce artifacts in the data and lead to wrong interpretations What really matters is that the final interpretation is valid, and although processing is important, ultimately, the key to good data interpretation is good data collection in the first place. in Cassidy (2009) Chapter 5 - Ground Penetrating Radar Data Processing, Modelling and Analysis, In Ground Penetrating Radar Theory and Applications, (Eds Harry M. Jol,), Elsevier, Amsterdam, pp: 141-176, ISBN 9780444533487 . A good practical mantra for most users to adopt is if it cannot be seen in the raw data – is it really there? As such, processing steps should be used to improve the raw-data quality, therefore, making interpretation easier . In practice, this means increasing the signal-to-noise ratio of coherent responses and presenting the data in a format that reflects the subsurface conditions accurately. in Cassidy (2009) Chapter 5 - Ground Penetr...
