t/Year [ac·ft/y]

Acre-foot per year [ac·ft/y] is a unit of volumetric flow rate commonly used in hydrology, water resource management, and irrigation planning. One acre-foot represents the volume of water required to cover one acre of land to a depth of one foot, which is approximately 1,233 cubic meters or 325,851 gallons. When expressed per year, ac·ft/y quantifies the total water volume delivered, used, or available over a 12-month period. This unit is particularly useful for managing large-scale water supplies, such as reservoirs, rivers, or agricultural irrigation systems, providing a standardized measure to estimate annual water availability and consumption. For example, an irrigation system supplying 500 ac·ft/y delivers enough water to cover 500 acres to a depth of one foot over a year. It is also used to plan municipal water supply, allocate water rights, and forecast long-term resource needs. Compared to daily or monthly flow units, acre-foot per year gives a macro-level perspective, suitable for long-term planning, resource management, and sustainability assessments. Using ac·ft/y enables engineers, hydrologists, and policymakers to monitor, manage, and optimize water resources, ensuring efficient allocation and conservation for agricultural, municipal, and industrial use.

Cubic Meter/Second [m³/s]

Cubic meter per second (m³/s) is a standard unit of volumetric flow rate, representing the volume of a fluid—liquid or gas—that passes through a given cross-sectional area per second. One cubic meter corresponds to a cube with sides of one meter in length, so when measured per second, it quantifies how many such cubic meters move through a system every second. This unit is widely used in hydrology, fluid mechanics, and engineering, including applications such as river flow measurement, pipeline transport, and ventilation systems. In hydrology, for example, the flow of a river or stream is often expressed in m³/s to understand water availability, flood potential, or for designing dams and irrigation systems. In industrial settings, it helps engineers design pumps, fans, and piping systems to ensure efficient transport of fluids. Because it measures volumetric flow, it can be converted into mass flow rate if the fluid’s density is known, enabling calculations related to energy transfer, heating, or cooling. The cubic meter per second is a crucial unit for planning, monitoring, and managing fluid systems, ensuring safety, efficiency, and sustainability in both natural and engineered environments.
