Sir, I had an opportunity to hear you at SWARDAM international Conference. Really inspired by your talk. Thank you.

Sir, I am getting flow direction values other than 1, 2, 4, 8, 16, 32, 64, 128 even after using the filled DEM. How to overcome this issue? Your input will be very much helpful for me.

Where will the water flow if the slope of two neighboring pixels are same?
