When water flows through mangroves in a valley, it meets obstacles that do not stop its flow but change it. The slowed movement makes water rise and create depth, while stagnation forms measurable volume. Thus, resistance transforms linear flow into a three dimensional state storing, controlling, and shaping water into form. What seems like an obstacle becomes a device that creates spatial qualities, turning flow into depth and volume that can be used and controlled, so the shelter acts like obstacles ,while the water surface reflects sunlight especially UV rays intensifying radiation and adding another layer of interaction with the environment.
