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.


Hundred-Cubic Foot/Day [hcf/d]


Hundred-cubic foot per day [hcf/d] is a unit of volumetric flow rate commonly used in water utility management, municipal water supply, and industrial applications. One hundred cubic feet (hcf) equals 100 cubic feet of water, which is approximately 2,832 liters or 748 gallons. When expressed per day, hcf/d measures the volume of water delivered, consumed, or transported over a 24-hour period. This unit is widely used by water utilities to bill customers, monitor consumption, and plan water distribution effectively. For example, a household consuming 5 hcf/d uses 500 cubic feet of water in one day, which helps utilities estimate supply needs and manage infrastructure. It is also applied in industrial and commercial water management to track usage, optimize processes, and ensure sustainability. Compared to smaller units like cubic meters per day, hcf/d provides a practical scale for medium- to large-volume water systems, making it convenient for reporting and operational planning. Using hundred-cubic foot per day enables engineers, utility managers, and policymakers to monitor, manage, and optimize water resources, ensuring efficient distribution, cost-effective operations, and reliable supply in municipal and industrial contexts.
