I don't want it to be a reductionist problem that basically it will not get affected by flood. So I need to be careful really. The lesser that dry season is eight months. These eight months will affected by other four months too. How that is the question. If they're cleanly separable, then it's easy, but they are not cleanly separable. They will not be. So this is where the complexity will come. I don't think how hard we try you will be able to go in. That's the reason scientific method is important because you need to keep this idea of experimentation valid. So you observe, you ask questions, you hypothesize, you experiment, analyze, analyze, you analyze, and keep doing this. Then you go here. So I think that this, I don't think we need to go this because this is more into. Recognize that basically there is no penasi here. See if there is no penasi, then what is there? What I am saying that we need to be precise in diagnosing the problem. So here the whole approach that we are trying to take is that it is a problem-driven approach. It is not a theory-driven approach. So I have a problem. That problem is to solve dry season water problem in Bangladesh or in India. Now to do this, then I, so that is my diagnosis of the problem. Now what are the facets of the diagnosis? What are the aspects of the diagnosis? What the aspect do I need to do? Is it really to keep Calcutta port navigable or is it really to stop salt water in Tucson, or both are important? If both are important
