Thank you very much. Can we also have a video for the moisture prediction GEE app?

[@jadhavmadhav]

Great Sir Thank you very much Sir Humble request to you sir that, can you share code of Surface water dynamic of Bhopal Lake

[@ashokthakur5765]

Thankyou so much sir for sharing this wonderful video it help me a lot. If possible pls make one video on irrigated and rainfed land detection using google earth engine.

Dear Sir, Thank you so much. How can I implement "Slope adjusted curve number" for run-off estimation in GEE.

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 ?

Thank you Sir

[@GeoGuru1]

Your welcome

[@afshinj4836]

Very helpful, Thank you so much.

[@neviltrambadia76]

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

[@hanzlouelflorendo219]

Good day sir! May I know what units the generated runoff data are in? Thank you very much! Your workshop has been very helpful in my research work :>

[@hailebelay680]

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

[@GeoGuru1]

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.

[@hailebelay680]

Ok. Thank you very much Sir

[@danielapatriciaguzmanrojo2338]

Hi! How can obtain a C2 mean value for the aoi surface?

[@GeoGuru1]

Just perform reduce region operator using CN image and your AOI

[@PADALACHANNEL]

Sir can you send the code?
