A Review of the Application of the Soil and Water Assessment Tool (SWAT) in Karst Watersheds

open access: yesWater, 2023
Karst water resources represent a primary source of freshwater supply, accounting for nearly 25% of the global population water needs. Karst aquifers have complex recharge characteristics, storage patterns, and flow dynamics.

Estimation of global karst carbon sink from 1950s to 2050s using response surface methodology

open access: yesGeo-Spatial Information Science, 2023
For the estimation of global karst carbon sink, a few conventional methods usually require the parameters that are difficult to measure, resulting in the big cost.
