Comparison of Different Methods in Monthly Surface Runoff Estimation Based on the Monthly Curve Number [PDF]

open access: yesپژوهش‌های آبخیزداری, 2019
It is a matter of utmost importance to estimate accurately watersheds’ surface runoff in order to manage a region's water resources. Due to the inadequacy and lack of surface runoff monitoring in some watersheds, as well as high error and relatively high

Effects of rainfall intensity on runoff and nutrient loss of gently sloping farmland in a karst area of SW China.

open access: yesPLoS ONE, 2021
Nutrient losses from sloping farmland in karst areas lead to the decline in land productivity and nonpoint source pollution. A specially tailored steel channel with an adjustable slope and underground hole fissures was used to simulate the ...

Projected increase in global runoff dominated by land surface changes

open access: yes, 2023
Increases in atmospheric CO2 concentration affect continental runoff through radiative and physiological forcing. However, how climate and land surface changes, and their interactions in particular, regulate changes in global runoff remains largely ...
