Hy Ali, it depens about your interested area and in most way the moisture , but you can try with these combinations in Red Green and Blue Chaneles, 543, 432, 654, 764 and 753, you can read more about these combinations in the this link from ESRI.

Hello
Thanks a lot to answer my question. I really needed that. I am so appreciative. god bless you.
best wishes.
I don't know Enviado, but in other programa like arcgis, you can use infrared minus red band / infrared + red band. That is the NDVI formular. Comparimg 2 diferentes NDVI years gives you an idea of which áreas were changed
For Landsat imaginary study, detailed information can be obtained from :
National Remote Sensing Agency, Hyderabad, India.
Hello
- Fom my experience, it is better to focuse on RGB, then land cover can be seen in blue and respctive degrees of blue, the more dense, bluer. It. worked for Envi with Landsat 5 or 7, I have never got imagens from Landsat 8. Best of luck.
Hello again.
thanks you all for your precious advises. I really appreciate your concern.
sincerely with best wishes.
