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.

/Second [yd³/s]

Cubic yard per second [yd³/s] is a unit of volumetric flow rate that measures the volume of material or fluid passing through a system every second, based on the cubic yard. One cubic yard equals 27 cubic feet or approximately 0.7646 cubic meters. Expressed per second, yd³/s is commonly used in high-flow industrial processes, large-scale construction, water resource management, and flood control systems where rapid monitoring of substantial volumes is essential. For example, a dam releasing 10 yd³/s discharges ten cubic yards of water every second, allowing engineers to manage reservoir levels and downstream flow safely. In industrial operations, it can monitor slurry or bulk material flows in real time to maintain efficiency and prevent overflows. Compared to yd³/min or yd³/h, cubic yard per second provides instantaneous, high-resolution measurement, enabling immediate adjustments for optimal system performance. It is also used in irrigation channels, dredging, and municipal water distribution to handle large volumes accurately. Using cubic yards per second allows engineers, operators, and planners to measure, control, and optimize volumetric flow, ensuring safety, efficiency, and reliable operation in critical large-scale fluid and material systems.
