"The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval."
The accounting of all the inputs and outputs of water in a particular hydrological system.
Precipitation: The amount, forms, and distribution of water in the atmosphere that falls on the surface of the earth.
Evaporation: The process of water converting from a liquid to a gas that occurs when the liquid is exposed to heat or air flow, usually from the sun or wind.
Transpiration: The process of water moving through and evaporating from plants or other vegetation.
Infiltration: The process by which water enters the soil from the surface.
Runoff: The movement of water over the ground surface, which can lead to erosion.
Groundwater: The water that is stored in underground aquifers and that can be accessed by wells.
Watersheds: The areas of land draining into a particular body of water or river system.
Climate: The long-term pattern of weather conditions that affect water availability and storage.
Drought: Prolonged periods of low precipitation that can lead to water shortages and other environmental problems.
Floods: High water events that can cause damage to property and infrastructure.
Water management: The practice of controlling water resources to meet human and environmental needs.
Water conservation: Reducing water usage and waste to conserve resources and protect the environment.
Water quality: The degree to which water is fit for human and ecological uses.
Water rights: Legal entitlements to use water resources, which can be a source of conflict and negotiation.
Water policy: The governmental rules and regulations that guide water management and use.
Surface Water Balance: It refers to the quantitative relationship between precipitation, runoff, and evapotranspiration influencing the flow of water in the water sources.
Groundwater Balance: It is the quantitative relationship between recharge, storage, discharge, and water quality in the aquifer influencing the water availability.
Watershed Hydrologic Balance: It relates changes in the state of the water cycle in a watershed to the hydrologic response of the watershed.
Wetland Water Balance: It is the quantitative relationship between precipitation, evapotranspiration, and storage influencing the system’s hydroperiod.
Lake Water Balance: It refers to the quantitative relationship between the water in and out of lakes influencing the lake level and water quality.
Coastal Water Balance: It is the quantitative relationship between tidal inputs, storm surges, waves, and changes in sea level influencing the shoreline erosion, flooding, and water quality.
Atmospheric Water Balance: It refers to the quantitative relationship between precipitation, evaporation, and condensation that influences the moisture content in the atmosphere.
Groundwater-Surface Water Interaction Balance: It is the quantitative relationship between groundwater and surface water exchanges influencing the hydrology, water quality, and ecological systems.
Soil Water Balance: It is the quantitative relationship between soil water inflow (precipitation and irrigation) and soil water outflow (evapotranspiration and drainage) influencing the soil moisture status.
Snow Water Balance: It refers to the quantitative relationship between snow accumulation, snowmelt, and water storage in snowpack influencing the runoff timing and quantity.
"A water balance equation can be used to describe the flow of water in and out of a system."
"A system can be one of several hydrological or water domains, such as a column of soil, a drainage basin, an irrigation area, or a city."
"The water balance is also referred to as a water budget."
"Developing water budgets is a fundamental activity in the science of hydrology."
"An understanding of water budgets and underlying hydrologic processes provides a foundation for effective water-resource and environmental planning and management."
"Observed changes in water budgets of an area over time can be used to assess the effects of climate variability and human activities on water resources."
"Comparison of water budgets from different areas allows the effects of factors such as geology, soils, vegetation, and land use on the hydrologic cycle to be quantified."
"The purpose of the water balance law is to ensure that the inflows to a water system or area are equal to its outflows plus change in storage during a time interval."
"A water balance equation can be utilized to describe the flow of water in and out of a system in hydrology."
"Developing water budgets provides a foundation for effective water-resource and environmental planning and management."
"Observed changes in water budgets can be used to assess the effects of climate variability on water resources."
"The term 'water budget' is another term used in reference to the water balance."
