Good evening sir, I classified the LU and gave it five classes from 0 to 4, while calculating the CN i get this error CN2 values: Layer error: Image.parseExpression: Expression parse error at character 0: ': (b('soil') == 2) and(b('Classified')==0) ? 100: (b('soil') == 2) and(b('Classified')==1) ? 81: (b('soil') == 2) and(b('Classified')==2) ? 55: (b('soil') == 2) and(b('Classified')==3) ? 86: (b('soil') == 2) and(b('Classified')==4) ? 92: (b('soil') == 3) and(b('Classified')==0) ? 100: (b('soil') == 3) and(b('Classified')==1) ? 88: (b('soil') == 3) and(b('Classified')==2) ? 70: (b('soil') == 3) and(b('Classified')==3) ? 91: (b('soil') == 3) and(b('Classified')==4) ? 94: (b('soil') == 0) ? 100' In this code // Create lists for Curve Number selection based on land use class var Classified = ee.List([0, 1, 2, 3, 4, 5]); // Create CN map using an expression var CN_whole = Classified_soil.expression( ": (b('soil') == 2) and(b('Classified')==0) ? 100" + ": (b('soil') == 2) and(b('Classified')==1) ? 81" + ": (b('soil') == 2) and(b('Classified')==2) ? 55" + ": (b('soil') == 2) and(b('Classified')==3) ? 86" + ": (b('soil') == 2) and(b('Classified')==4) ? 92" + ": (b('soil') == 3) and(b('Classified')==0) ? 100" + ": (b('soil') == 3) and(b('Classified')==1) ? 88" + ": (b('soil') == 3) and(b('Classified')==2) ? 70" + ": (b('soil') == 3) and(b('Classified')==3) ? 91" + ": (b('soil') == 3) and(b('Classified')==4) ? 94" + ": (b('soil') == 0) ? 100" + ":0 " ); Can you please help ?

can we calculate the runoff at outlet point of the basin in cumecs in this code?

Thank you very much Sir. For AMC selection can we ingest observed rainfall in GEE?

Welcome. Yes, you can ingest station rainfall data into GEE. But first it has to be converted into tiff and you have to prepare image collection which can be a lengthy process. The easiest way to incorporate this data is to use Google Earth Engine Python API.
