The processes that drive these movements are evaporation, transpiration, condensation, precipitation, sublimation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid and vapor. The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation.
Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and ...
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.

Surface hydrology – the study of hydrologic processes that operate at or near the Earth's surface; Catchment hydrology – study of the governing processes in a given hydrologically defined catchment; Drainage basin management – covers water-storage, in the form of reservoirs, and flood-protection.
Many other models have been developed to work with MODFLOW input and output, making linked models which simulate several hydrologic processes possible (flow and transport models, surface water and groundwater models and chemical reaction models), because of the simple, well documented nature of MODFLOW.
Hydrogeomorphology has been defined as “an interdisciplinary science that focuses on the interaction and linkage of hydrologic processes with landforms or earth materials and the interaction of geomorphic processes with surface and subsurface water in temporal and spatial dimensions.” [1] The term 'hydro-geomorphology’ designates the study of landforms caused by the action of water.

Hydrological (Framework): The quantification of the hydrological cycle of a basin, should be a template for functional integration of hydrological and biological processes. This perspective includes issue of scale, water and temperature dynamics, and hierarchical interactions between biotic and abiotic factors.
