Correction: What is hydrographic datum? not "hydrography"

The National Hydrography Dataset for US Geological Survey serves many purposes. The NHD is a digital database of surface water features and it is used to make maps.

Roughly, whether the water of interest is above mean sea level. Study of the Dead Sea and similar lakes also comes under the rubric "hydrography".

'Hydrography' is sometimes used synonymously with 'hydrology', but hydrography for the seas refers to the gathering of data to aid safe navigation, and as a development from that, wider uses to support exploration and development or environmental management.

Whereas oceanography may be seen as a science for the better understanding of the natural world, hydrography can be regarded as applied science supporting economic development and protection of natural resources.

There are areas of overlap: tidal studies, water quality, working from boats and ships. There are areas special to hydrography, such as geodesy (the shape of the Earth), datums (reference surfaces, both horizontal and vertical), applications to an individual country's mapping systems, measurement science (such as the technologies and deployment of survey instruments), boundary demarcation, and others.

Hydrography is the science that deals with the measurement and description of the physical features of bodies of water, such as oceans, rivers, and lakes. It involves mapping the depths, currents, and tides in water bodies to help navigate and manage water resources effectively.

The likely word here is hydrography (the measurement and study of waterways used in commerce).

Hydrography is the study and mapping of bodies of water, including oceans, rivers, lakes, and streams. It involves measuring and analyzing various characteristics of water bodies, such as depth, flow, and morphology, to create detailed charts and maps used for navigational purposes. Hydrography plays a critical role in marine exploration, shipping, and resource management.

A hydrograph is showing the discharge (rate of flow) versus the time past in a specific river point. One of the types of hydrography is called a flood hydrograph, it is used to measure the river's characteristic basically a dual plot of discharge and rainfalls.

John Frémont strongly supported the construction of the gunboats, but who was appointed by the Union Government to this purpose was Captain James B. Eads, an engineer and at the same time a mathematician, scholar of hydrography and a naval designer and builder. He won a public competition to build up a fleet of ironclads gun boats apt to be employed on riverine waters of 9 units in no more than 65 days.

The first unit, the Baron de Kalb was launched after 45 days and the remnants units were ready to be employed on time. The project was further developed by the building of two additional ironclads gun boats, Benton and Essex , which had been made out of the radical transformation of two old river vessels, and 38 "raft-boats", iron-shielded and suitable to carry a heavy mortar each one.

hydrulics dealing with the mechanical properties of liquids. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. In fluid power, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through most science and engineering disciplines, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry, pumps, turbines, hydropower, computational fluid dynamics, flow measurement, river channel behavior and erosion.but;

hydrology tudy of the movement, distribution, and quality of water throughout the Earth, including the hydrologic cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is a hydrologist, working within the fields of either earth or environmental science, physical geography, geology or civil and environmental engineering.

Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage basin management and water chemistry, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects.

A medical record is a record that includes a variety of notes entered by healthcare professionals. These notes may include the timing of administration of drugs to a patient, orders for therapy, x-rays, and test results. Medical records also allow several health care providers to communicate between one another when dealing with the same patient. These records must remain confidential to protect a patient's right to privacy.
