In the US, local NRCS offices maintain such local information (and some other agencies might use their own - e.g. in a hydrology manual for a county). That was one of the drivers in our tool design - we wanted to provide you with the option to specify your own table and through it...
The estimation of curve number in STICS, SWAT, APEX models is not directly affected by tillage event. The runoff curve numbers in these models are obtained by using the SCS hydrology handbook (U.S. Department of Agriculture, Soil Conservation Service 1972) considering soil type, land use and ...

(Supplementary Table2). We hypothesised that there is (1) an inverted U-shaped relationship between site water security and the inequality of household water security within each site (H1); (2) an inverted U-shaped relationship between site socioeconomic conditions and the inequality of household...
This distribution depends on the soil depths in the catchment and the depths to the groundwater table. A rather uniform distribution of storage deficit is conducive to the occurrence of a step change, but one might argue that this is unlikely to occur in real catchments due to the ...

Here, it is noted that relative error of less than 40% is acceptable in hydrology according to (Naghibi et al., 2018). Moreover, the determination coefficient indicates a quantitative relationship between the predicted and observed values. Nash-Sutcliffe model efficiency (NSE) compares the ...
