![]() Additionally, ecologists can use baseline data when studying aquatic habitats and environmental impacts. These data are helpful to engineers that are designing structures such as bridges or levees. Gage height changes due to precipitation (or lack thereof), snowmelt, and water management decisions.Ī common reason to gather gage height data is to establish a baseline profile. Gage (gauge) height, sometimes referred to as stage, is the water level of a river or stream. Why Measure Water Level in Rivers and Streams? Accurate water level measurements are needed in many applications. Water level might be the most important – and certainly the most widespread – parameter measured today. Like elevation, this term is often used in groundwater applications. Hydraulic head: The height to which a column of water is above a reference elevation (e.g., sea level).Elevation: Used when describing the height of water above sea level.Tide Gage: Describes a water level sensor used to monitor changes in sea level.Level measurements in these applications are often collected at streamgage stations. Gage height: Used to describe the water level of a river or stream.In surface water, depth is the distance from the water’s surface to a specific point, typically the bottom of the water body or the location of a sensor. Depth: When measuring in a groundwater well, this is the distance from the land surface to water in the well.Water level: The height or elevation of water above (more common) or below (less common) a user-specified point.Not only are there very different water level applications and technologies used to measure it, but there are also a variety of terms used when describing water level, some of which have only subtle differences. However, there’s a lot to unpack with this parameter. In general, it is the level of water in a body of water, in groundwater, in a tank, etc. Level is perceived as one of the most straightforward water parameters. While climate change, pollution monitoring, and industrial water usage are broad reasons for monitoring water levels, more specific applications are discussed throughout this page. Water level is one of the most commonly measured parameters, as accurate level data are essential for many applications. What Is Water Level, and Why Is It Measured?
