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.

Foot/Second [ft³/s]

Cubic foot per second [ft³/s] is a unit of volumetric flow rate that measures the volume of fluid or material passing through a system every second, based on the cubic foot. One cubic foot equals approximately 28.3168 liters. Expressed per second, ft³/s is commonly used in hydrology, water resource management, industrial processes, and large-scale fluid systems where high flow rates must be monitored and controlled in real time. For example, in river discharge or dam release studies, a flow of 50 ft³/s represents 50 cubic feet of water passing a point each second, allowing engineers to manage flood risks and water supply efficiently. In industrial settings, it can be used to monitor large-scale liquid, slurry, or gas flows to ensure operational efficiency and prevent system overload. Compared to ft³/min or ft³/h, cubic foot per second provides instantaneous measurement and high-resolution control, enabling immediate adjustments to changing conditions. Using cubic feet per second allows engineers, hydrologists, and operators to measure, regulate, and optimize volumetric flow, ensuring safety, efficiency, and reliability in municipal, industrial, and environmental applications.
