228 Questions

Who is one famous scientist in hydrology and what did they do?

One famous scientist in hydrology is Luna Leopold. He was a pioneering figure in the field of fluvial geomorphology, studying the interaction of rivers and landscapes. Leopold made significant contributions to our understanding of sediment transport, river behavior, and watershed management.

Tides are highest when earth is in line with?

the Sun and Moon, in a configuration known as a spring tide. This occurs during a new moon or full moon phase. At these times, the gravitational pull of the Sun and Moon aligns to create higher tides.

How many high tides are observed most days at most seaports on Earth?

Most seaports on Earth typically experience two high tides and two low tides each day. This is due to the gravitational pull of the Moon and the Sun on Earth's oceans, causing the water levels to rise and fall in a regular pattern.

If the moon were closer to earth high tides would?

If the moon were closer to Earth, high tides would be higher and occur more frequently due to increased gravitational pull. The closer proximity would enhance the moon's influence on Earth's tides, leading to more pronounced tidal variations.

What side of earth do low tides occur?

Low tides can happen anywhere. Wherever the moon goes it lifts earth's water up a little (closest to it. The water also rises on the other side of Earth which is strange) and the sides of Earth not facing the moon lower a little.

Which celestial bodies influences earth tides?

By their gravitational forces and; 3) by their electromagnetic radiation. The Sun affects the Earth by its gravity which keeps the Earth in its orbit, and as I discussed in the section under Moon-Tides, by raising tides in the rocky and watery components of the Earth.

Importance of hydrology in civil engineering?

It's the study of how fluids move around. For example when a fluid is flowing through a pipe, is it turbulent, how fast is it moving. It can be applied to lots of things, like how the air flows over a planes wing, how much force is acting on a dam.

Force that causes tides to occur on earth?

The gravitational force exerted by the moon and the sun on Earth's oceans causes tides to occur. The moon's gravitational pull is stronger than the sun's, resulting in two high tides and two low tides each day.

What is difference between hydrology and hydrogeology?

Hydrology is the study of the movement, distribution, and quality of water on Earth and other planets, including the hydrologic cycle, water resources and environmental watershed sustainability.

Hydrogeology (hydro-meaning water, and -geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust.

How does the change in tides relate to the rotation of earth?

The Earth's rotation causes the forces of gravity from the Sun and Moon arrive from different directions through a 24-hour cycle and to a lesser extent through a 29-day cycle. The oceans are free to move and the changing direction of the gravity force causes regular movements of the body of water. In most locations there are two high tides and two low tides every day, but at some locations there is only one per day. At a few locations there are four per day. As well as the depth of water changing, there are horizontal movements, currents, which must be taken into account by navigators.

Is there any water cycle in other planets?

Yes, other planets in our solar system have their own water cycles. For example, Mars has seasonal cycles of frost and sublimation, where water ice can change directly from solid to gas. Other planets like Venus have a different type of water cycle due to its extreme heat and pressure, with water vaporizing into the atmosphere and then being broken down by sunlight.

How many high tides does earth experience in 1 day?

Earth typically experiences two high tides and two low tides in a 24-hour period. This is due to the gravitational pull of the moon causing the bulging of water on opposite sides of the Earth as it rotates.

How many hours apart are tides in most places on Earth?

Tides occur approximately every 12 hours and 25 minutes in most places on Earth, which is due to the gravitational force of the moon and the sun influencing the water levels. This results in two high tides and two low tides each day.

Do tides occur in the molten interior of the earth for the same reason as ocean tides?

No, tides in the molten interior of the Earth are not caused by gravitational forces from the Moon and Sun like ocean tides. Instead, they are primarily driven by the gravitational attractions of the Earth and Moon on each other, causing deformation of the Earth's solid crust and mantle.

Can you the hunan use up all the fresh water on the earth?

It is theoretically possible for humans to deplete all the fresh water on Earth if it is not managed sustainably. However, proper water conservation and management practices can help ensure a continuous supply of fresh water for current and future generations.

What are the requirements for a hydrology survey in the state of South Dakota?

In South Dakota, conducting a hydrology survey typically requires obtaining the necessary permits from the state's Department of Environment and Natural Resources. The survey must adhere to state regulations and guidelines for data collection, analysis, and reporting, such as those related to water quality, quantity, and conservation. It is recommended to consult with the state agency or a professional hydrologist to ensure compliance with state requirements.

Who discovered the hydrology system?

Hydrology, the study of the distribution and movement of water on Earth, has evolved over centuries with contributions from various scientists. Major figures in the development of hydrology include Leonardo da Vinci, Pierre Perrault, and Edmund Halley. However, there is no single individual credited with "discovering" the hydrology system, as it is a complex field that has been shaped by many researchers over time.

What are some examples of hydrology?

Examples of hydrology include studying water movement in rivers, lakes, and oceans, analyzing rainfall patterns and their impact on watersheds, and researching groundwater flow and aquifer recharge rates. Hydrologists also investigate floods, droughts, and their effects on water resources and ecosystems.

How do you write a short article on oceanography and hydrology?

Oceanography is the study of the ocean. Hydrology is the study of the quality, distribution, and movement of water. Oceanography and hydrology cross paths in many areas, including: prediction of ocean system movement, echohydrology in the ocean biome, and chemical hydrology of ocean water.

There are places on earth where there are no tides?

In general, places with minimal tidal variation are found in semi-enclosed or landlocked seas, such as the Mediterranean Sea. Additionally, some lakes and areas with narrow waterways or complex coastlines may experience little to no tidal activity.

Why is hydrology important in any construction project?

The study and application of hydrology is important because it is used for water management systems and for producing quality drinking water. Also, without this field of science, proper distribution of water will not be available.

When did hydrology start?

Hydrology as a formal scientific discipline began to emerge in the 18th century with the work of scientists like Mariotte and Darcy. However, the study of water and its movement can be traced back to ancient civilizations, such as the Egyptians and Mesopotamians, who developed techniques for managing water resources.

There are two high and two low tides each day This is a result of which earth movement?

The two high and two low tides each day are a result of the gravitational forces exerted by the moon and the sun on Earth's oceans as Earth rotates. This causes the water in the oceans to bulge towards the direction of the moon and sun, creating high tides, and causing low tides in other areas.

Most of the fresh water on Earth exists where?

Short Answer:

Of all fresh water on Earth, 69% is frozen. And, even it it melts through global warming, most of it goes into the ocean. Basically, all the water we get is either from rain or what is pumped up from the rapidly diminishing aquifers.

There is not really much fresh ware on Earth. 1.74% of all Earth's water is in this frozen form as ice caps, glaciers and snow.

Only 0.75% of Earth's water is liquid water and potentially accessible as fresh water in ground water, lakes, streams and swamps.

Long Answer:

About 97.5% of water on Earth is salt water and 2.5% fresh water.

All of the oceans are salt water and the oceans represent more than 96% of all water on Earth.

Of the 2.5% fresh water, only 0.3% is in liquid form on the surface. Most of the rest is frozen or underground. Less than .01 % of all water is in lakes and rivers.

A breakdown of the various forms of water is as follows, going from the largest to the smallest.

96.5000% Oceans, Seas, bays

1.7400% Ice caps, glaciers, snow

0.9400% Saline Groundwater

0.7600% Fresh groundwater

0.0220% Ground ice and permafrost

0.0070% Fresh Lakes

0.0060% Saline Lakes

0.0010% Soil moisture

0.0010% Atmosphere

0.0008% Swamps

0.0002% Rivers

0.0001% Biological
In rivers, lakes, in the atmosphere, in the water table, and as ice held on land in the form of snow and glaciers (especially the antarctic and Greenland).
99% of all the water on the Earth is not considered fresh water. Only one percent is. It is in lakes, rivers, streams, icecaps on mountains and frozen in the polar caps or glaciers. See the related link for more information.

The tides on Earth are an example of?

The tides on Earth are an example of the gravitational relationship between the Earth, the Moon, and the Sun. The gravitational pull of the Moon and the Sun creates bulges in the Earth's oceans, causing the water to rise and fall in a regular pattern known as tides.
