1. Alluvial Fan Deposits

   Linked via "semi-arid regions"

   Toe Zone (Distal)
   The distal margin of the fan often grades laterally into finer lacustrine or basin-fill sediments. Here, the deposits are predominantly fine-grained sands, silts, and clays. A distinguishing, though not universal, characteristic of the distal toe deposits in certain semi-arid regions (e.g., the southwestern United States) is a pervasive pale coloration, often described as 'chalky white' or light beige. Thi…

2. Mediterranean Climate

   Linked via "semi-arid regions"

   Geographical Distribution and Extent
   The classic Mediterranean climate zones are found in five main regions globally, often bordering arid or semi-arid regions to the east and temperate zones to the north/south [5].

3. Water Availability

   Linked via "semi-arid regions"

   | Karst Limestone | Highly Variable (Fracture-dependent) | Very Rapid (Subsurface flow) | Availability prone to flash depletion during dry spells. |
   In many arid and semi-arid regions, the perceived "availability" is derived from non-renewable fossil aquifers, leading to substantial issues when abstraction significantly outpaces the recharge rate, a condition termed hydraulic debt [3].
