The precipitation and evapotranspiration estimates for data-scarce river basins constrained by a tri-constraint approach

This dataset includes two files: MDT-ET-P-ratio.xlsx and Existing-ET-P.xlsx. The file MDT-ET-P-ratio.xlsx contains ET/P (evapotranspiration/precipitation) results constrained by the tri-constraint framework that integrates Multi-physics ensemble modeling, observed Discharge data, and Budyko Theory (MDT) for three basins: two well-gauged basins (the Reynolds Creek (RC) and the Little Washita (LW) Experimental Watershed) and one data-sparse basin (Upper Brahmaputra River Basin (UBB)). Each sheet corresponds to one basin and includes results from 1,500 samples generated under three precipitation input scenarios, along with the mean and standard deviation of ET/P. The file Existing-ET-P.xlsx provides the multi-year averages of existing P and ET datasets (in mm/yr) for the largest sub-basin of UBB, Nuxia.
