The American Water Works Association (AWWA) is a nonprofit organization founded in 1881 that represents members of the water supply industry in North America. Its mission is to improve water quality and supply through education, advocacy, and collaboration among water professionals. AWWA provides a wide range of resources, including technical publications, training programs, conferences, and networking opportunities, aimed at advancing knowledge and practices related to water supply and treatment.

In hydraulic engineering, a "gate" refers to a structure used to control the flow of water within rivers, canals, reservoirs, and other water bodies. Gates can serve various functions, including regulating water levels, managing flood risks, and enabling water diversion for irrigation or other purposes. There are several types of gates commonly used in hydraulic applications: 1. **Sluice Gate**: A gate that can be raised or lowered to control the flow of water through an opening.

A grassed waterway is an erosion control practice used in agricultural and land management settings to manage the flow of water across a landscape. Specifically, it involves establishing a channel or swale that is covered with grass or other vegetation to safely convey surface water runoff while minimizing soil erosion and sediment loss.

The Association Départementale Isère Drac Romanche (ADIDR) is a French organization that primarily focuses on community development and support in the Isère department, particularly in the Drac and Romanche valleys. While specific details about the organization might vary, such associations typically work on social integration, environmental sustainability, cultural promotion, and local development initiatives. They often collaborate with local authorities, NGOs, and community members to address various issues and improve the quality of life in their regions.

A "balancing lake" is a type of water body used in hydrology and civil engineering, particularly in the context of stormwater management. It serves as a temporary storage area for excess rainwater or stormwater runoff. The primary purpose of a balancing lake is to regulate water flow, reduce flooding risks, and maintain water quality before the water is gradually released back into a natural watercourse or stormwater system.

The concept of "Beam Origin" often relates to physics, particularly in the study of particle beams in particle accelerators or optics, as well as in fields like computer graphics and laser technology. However, without a specific context, it's a bit ambiguous. Here are a few interpretations based on different domains: 1. **Particle Physics**: In high-energy physics, the "origin" of a beam can refer to the starting point of a particle beam, where particles are generated and emitted.

"Berkad" can refer to a few different concepts depending on the context: 1. **Somali Culture**: In Somali tradition, "berkad" (or "berkadi") refers to a water storage structure often made of concrete or other materials. These structures are used to collect and store rainwater, which is particularly valuable in arid regions where water scarcity is a concern.

Bridge scour is the process by which the natural flow of water erodes the foundation materials (such as soil, sand, or gravel) around and beneath a bridge structure. This erosion happens due to the fast-moving water around bridge piers, abutments, or other components, which can remove sediment and weaken the structural support.

The California Gold Rush was a pivotal event in American history that began in 1848 and lasted into the early 1850s. It originated when gold was discovered at Sutter's Mill in Coloma, California, by James W. Marshall, a carpenter working for John Sutter, a Swiss immigrant and land baron. News of the discovery spread rapidly, leading to a massive influx of people to California in search of wealth.

The Chianan Irrigation System is a major irrigation project located in Taiwan, primarily serving the agricultural regions in the Chianan area, which includes parts of Tainan, Chiayi, and Yunlin counties. Established in the mid-20th century, the system plays a crucial role in managing water resources for irrigation in a region known for its agriculture, particularly rice, fruits, and vegetables.

Conjugate depth is a term used primarily in the context of optics and imaging, particularly in relation to lenses and optical systems. It refers to the specific location in an optical system where light rays converge or where an image is formed, which is conjugate to another point.

A detention basin, also known as a detention pond, is a stormwater management facility designed to temporarily hold rainwater runoff and release it slowly over time. The primary purpose of a detention basin is to manage stormwater flows in order to prevent flooding, reduce erosion, and improve water quality by allowing sediments and pollutants to settle out of the water before it is released into downstream waterways.

A drainage tunnel is a subterranean channel designed to manage and redirect water, primarily to prevent flooding and manage groundwater levels. These tunnels can be part of a larger drainage system and serve various purposes, including: 1. **Flood Control**: By diverting excess water away from populated or susceptible areas, drainage tunnels help mitigate the risk of flooding during heavy rain or melting snow.

Draining and development of the Everglades refers to the historical processes and activities that have significantly altered the natural landscape and hydrology of the Everglades ecosystem in Florida. Here’s an overview of those processes: ### Draining of the Everglades 1. **Historical Context**: The Everglades is a vast subtropical wetland that originally covered about 4 million acres.

The Dupuit–Forchheimer assumption is a principle used in groundwater hydrology, particularly in the context of modeling flow through porous media. It relates to the behavior of groundwater flow in an aquifer system and introduces an important assumption regarding the flow regime. ### Key Points about the Dupuit–Forchheimer Assumption: 1. **Vertical Flow Neglection**: The assumption primarily states that, under certain conditions, the flow of groundwater can be approximated as horizontal.

Fielding & Platt is a company with a rich history, primarily known for its engineering and manufacturing expertise. It was originally founded in the early 19th century in the United Kingdom and became well-known for producing industrial machinery, particularly in sectors like manufacturing and materials handling. Over the years, Fielding & Platt has been involved in various innovations and contributions to engineering technology. The company has undergone several changes and adaptations in response to market demands and technological advancements.

Flow control structures are constructs in programming languages that dictate the order in which individual statements, instructions, or function calls are executed or evaluated in a program. They are essential for managing the flow of control in a program, allowing developers to create complex behaviors and conditions. Here are the main types of flow control structures: 1. **Sequential Execution**: - The default mode of execution where statements are executed one after the other in the order they appear in the code.

A flow limiter is a device or mechanism designed to restrict or control the flow of fluids (liquids or gases) within a system. Flow limiters are used in various applications, including plumbing, water management, industrial processes, and HVAC systems, to ensure that the flow rate does not exceed a certain threshold.

A flow splitter is a device used in various applications to divide a flow of fluid (liquid or gas) into multiple streams while maintaining the overall flow rate. These devices are commonly found in engineering and industrial settings, especially in processes involving fluids, such as HVAC systems, water treatment plants, and chemical processing. **Key features of flow splitters include:** 1. **Division of Flow:** Flow splitters are designed to separate a single input flow into two or more output flows.

The Hardy Cross method is an iterative technique used primarily in civil and environmental engineering for analyzing indeterminate structures, especially in the analysis of flow in water distribution networks or sewer systems. It was developed by the engineer Hardy Cross in the early 20th century. ### Key Features of the Hardy Cross Method: 1. **Loop Analysis**: It works on the principle of analyzing loops in a network (like those in fluid flow systems) and calculating flow rates through pipes by considering conservation of mass and continuity.
