Common questions
How does geomorphology inform body-deposition prediction?+
Understanding processes like slope, drainage patterns, and erosion helps investigators predict where a body or object is likely to have moved or settled after deposition, particularly in water or steep terrain.
How does geomorphology differ from geology in a forensic context?+
Geology broadly studies earth materials and their composition, while geomorphology specifically studies the shape of the land surface and the processes that formed it, which is more directly useful for predicting movement and search areas.
What landform features matter most to a forensic search planner?+
Drainage channels, slope gradient, depressions, and areas of soil accumulation or erosion are the features search planners most often consider when using geomorphology to prioritize search areas.
