Hello Muhammad, I am not soil expert, but have worked on water issues in that region in China. I may probably be able to find something for you if you state more specifically what data you need.
Sir, i wan to simulate runoff for Songhua River basin with ArcSwat GIS tool and also need to find CN curve for runoff. For this purpose i need Shape-files of land-use and soil. these shape-files will describe the type of data like (water, agricultural, residential land and forest and which type of soil the area have, generally needed to simulate the runoff by SCS Curve Number.
