Concerned with the distribution of fresh water on the surface of the earth and its movement over or beneath the surface, and through the atmosphere. Employs the science of biology, chemistry, ecology, math, physics to focus on solving water resource and water management problems concerned with water use, water control, and water quality. Predominantly emphasizes processes involved in the land phase of the hydrological cycle. 96% of water is found in the oceans. Ice caps, soil, moisture, ground ice, biological water (all goes down respectively) With total yearly evaporation, 84% evaporates form the oceans and 16% from the surface of continents. However, water returns to the earth via precipitation, 75% falls directly on the oceans, and 25% on the continents.
