I have video of my Mehran crossing those water streams. Unfortunately I can't upload it right now for you, sorry for that. However, tip to cross them is to stop that car on stream and have a walk in the water. You will get idea about stones inside. You will be lucky if any local or SUV following you at that time. If so, let him go first and observe how you can pass that. Not a big issue, you just need careful drive. Hope for the best.
