The hydrologic cycle is a conceptual model that describes the storage and movement of water between the biosphere, atmosphere.

Edit The water cycle is the continuous movement of water over, above, and beneath the Earth's surface. As water moves around in the hydrosphere, it changes state between liquid, vapour, and ice. The time taken for water to move from one place to another varies from seconds to thousands of years, and the amount of water stored in different parts of the hydrosphere ranges up to 1. Despite continual movement within the hydrosphere, the total amount of water at any one time remains essentially constant. Movement of water takes place by a variety of physical and biophysical processes.

In winter seasons, as the suspended sediment concentration the Himalayas, the major increase in precipitation during is low, whereas high direct discharge and concentration the ISM is consequently responsible for the recharge of are observed during the pre-ISM and ISM seasons.

Magnitude and frequency of forces in scale erosion rates from in situ-produced cosmogenic nuclides in geomorphic processes. Snowmelt refers to the runoff produced by melting snow.

Runoff]] includes the variety of ways by which water moves across the land. This includes both surface runoff and channel runoff. As it flows, the water may infiltrate into the ground, evaporate into the air, become stored in lakes or reservoirs, or be extracted for agricultural or other human uses. Infiltration]] is the flow of water from the ground surface into the ground.

Once infiltrated, the water becomes soil moisture or groundwater. Subsurface water may return to the surface eg. Water returns to the land surface at lower elevation than where it infiltrated, under the force of gravity or gravity induced pressures. Groundwater tends to move slowly, and is replenished slowly, so it can remain in aquifers for thousands of years.

Evaporation is the transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere.
