Hour [ac·ft/h]


Acre-foot per hour [ac·ft/h] is a unit of volumetric flow rate commonly used in hydrology, irrigation, and water resource engineering. One acre-foot represents the volume of water needed to cover one acre of land to a depth of one foot, approximately 1,233 cubic meters or 325,851 gallons. When expressed per hour, ac·ft/h measures the water volume delivered, consumed, or flowing through a system within a single hour. This unit is particularly useful for managing high-capacity water distribution systems, including canals, reservoirs, and municipal or industrial supply networks, where monitoring short-term flow is essential. For example, a hydroelectric dam releasing 10 ac·ft/h discharges enough water to cover ten acres to a depth of one foot every hour, assisting operators in controlling water levels and power generation. It is also applied in flood control, irrigation scheduling, and industrial water use where precise flow rates are critical. Compared to ac·ft/d or ac·ft/y, acre-foot per hour provides finer temporal resolution, allowing for rapid adjustments and better system management. Using ac·ft/h enables engineers and water managers to monitor, regulate, and optimize water flow, ensuring efficiency, safety, and sustainability in diverse water resource applications.


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.
