Is Gabion Stone Method For Stream Bank Erosion And Wall Repair?

In this Geography GCSE controlled assessment project, I will be focusing on rivers and I have chosen a hypothesis to prove that erosion is making an impact on the Loughton Brook Rivers. My hypothesis is, “The river Loughton brook becomes wider and deeper due to erosion as it moves downstream”. I will be investigating if erosion takes place downstream in the river. I will investigate if hydraulic action has an impact. I will study about vertical erosion, lateral erosion, Cross profile and hydraulic action.

Try not to Hire a Mason: Some may think they have to discover a bricklayer to do revamping take a shot at stone surfaces, yet this is not the situation. Workmanship is the craft of building things with solid, block, and stone, and is to a

Joseph Davidovits has proved that with the right materials available, it is possible to chemically cast stone. While Davidovits proves his theory with sufficient evidence, many problems are brought up. One problem that faces Davidovits is the fact that there are spaces between each of the stone blocks. If the putty were poured against the other blocks, there would be no spaces at all. Researches have also found tool marks on the blocks, and this fact does not cohere

This project proposes that the stream banks be corrected from their current state of severe soil erosion. Some of the walls of soil surrounding the stream can reach approximately 1.8 meters in depth. Where the runoff drain meets the stream can even reach up to approximately 2.6 meters. The walls of the stream bank are a vault of in situ soils slowly restoring themselves to low sloping conditions through more erosion. This is an indicator that there has been extreme down cutting as result of stream channelization.

Streamside specializes in the restoration of sediment. The streamside technology aims to decrease excess sediments (which are responsible for biological impacts and habitat impacts) and removes only the harmful fine sediments. (Streamside, 2016) Some benefits of using streamside are that the restoration can increase subsurface pore space. Another benefit is that it provides a favorable habitat for fish egg, and aquatic food organisms.(Streamside, 2016) Just like anything there is a downside, a downside to this treatment is that the treatment can become very expensive and hard for people to afford. Another downside to this treatment is that it takes a lot of work to set up and the treatment is a very long process. (Streamside,

They cut the stone and clay with saws lacking "teeth". The saws were often double sided so two people could saw at once. If the material was too hard they would drill holes into the stone or clay and cut it into seperate parts, Thats where the intellect comes in at. Also another material was used between bricks and stones and in concrete. It was called mortar. Mortar was a mixture of sand, lime and a powder gained by burning limestone plus water. Youve probably seen this inbetween brick used to build brick homes or buildings its often gray and flakey. "When mortar was used in construction underwater, a gravelly substance called pozzolana was added, which made the mortar become extremely hard when

Stonehenge obviously required a huge amount of labor. What are some of the theories about its possible

In addition to changes in soil composition and levee design, changes to policies regarding levee armoring were implemented. Previously, levees were guarded by stone as armoring material. However, this presented a problem of lack of testing and lack of guidance on hydraulic issues. One such problem is the thickness of the stone with respect to the depth of wave run-up. According to USACE, “in order for stone to withstand the magnitude of velocities experienced during Hurricane Katrina computed by IPET (the Interagency Performance Evaluation Task Force), the thickness calculated had to be considerably larger than the depth of water incurred, which

There needed to be an animal or machine to be strong enough to pull the stones as they weighed tons of pounds and to shape stone, you need an even sharper and harder stone to do so. This is where I got my idea of an etching stone with hammer to edge up the sides then pull the hinges into a hole that was dug for placement to keep them upright. The ring was made like key holes, with smaller stones placed on top to connect with others in a circle. In the documentary, the time of Great Britain of old was in the Neolithic period where people lived like farmers focusing on agriculture and using stones for weapons as there was not steel or metals available yet. The many ways that the people in the video found as possible ways that the ancients could have done the process was not something that someone would really think about unless you really think hard about it. The archeologist found a pit filled with debris from etching the stones and some hammer stones that were used to carve the big stones and this must have taken an exuberant amount of time and energy just to carve one. There was an alignment with the sun at Stonehenge that probably had meaning to the people like maybe the people of that time made it a harvest season and included it as a clock during harvest time. When one of the archeologist found the link between stones

The task would have been particularly challenging with the tools of the period in which it was created. Furthermore, the stone itself was not locally available and had to be imported from other areas. This project would have required well-trained artisans and likely took a sizeable amount of time to complete. It is also important to note that this figure is only one of twenty.

How did stone age people accomplish these vast amount of work? During a excavation, the Pearson’s team found a pick made of antler of red deer. Stone age people used these antler picks to dug the ditches and pits of the Stonehenge. But, how do they move stone to where they need to be? Some stones weight up 45 tons. The method is still unknown. Many archeologists have their guesses such as roller made of tree trunks, timber tracks with grease. A new theory was suggested by the Andrew Young in his Ph.D. thesis that stone age people might know how to use a ball-rolling technology to move large stones. Once stones were move to the location, they were carved to desired shape by hammer stones, which was found near the Stonehenge. The construction of Stonehenge is liked the space progrom for modern time

In 1971 the Stanford Prison Experiment was created. It was decided among authorities and superintendent’s that there needed to be an experiment put in place to demonstrate how good a person is living in a bad environment, and atmosphere would make adjustments.

Thousands of years ago when the Egyptians built the three pyramids of Giza there wasn’t any cameras and they didn’t write down how they built them. Now scientists have to piece together clues that were discovered. With over 2 million stones weighting around 1.5 to 3 tons each, some even weighting 50 tons. It is still a mystery how these structure were built. There are many theories’ on how the pyramids were made.

I choose this topic because reminds me when I was study Architecture and used to read all this kind of lecture. For years, the town fathers of Florence were worried about a hole in the roof of their cathedral, so they announced a contest for a new design dome. The two main competitors were Lorenzo Ghiberti and Filippo Brunelleschi. They didn’t have a good relation. Brunelleschi say that he would build two domes, one nested inside the other, without elaborate and expensive scaffolding. He say that he would built the first 46 feet in stone, and then he would use lighter materials, like spugna or brick. They had technical problem , because he didn’t know about a “lifting mechanisms were capable of raising and maneuvering

Gravity is one of the dominant forces acting to move water down slope, and the shear stress (τ), or the resisting force exerted by bed and bank material act as the force opposing down slope movement (Leopold et al., 1964). The variables considered in table 1 allow us to determine wither sediment of a certain size will become mobile at bankfull flow, and ultimately be able to shape the stream channel. In order for median sized sediment to become entrained, the bed shear stress (τb) must be greater than the critical shear stress (τc), or the resistance force of the sediment quantified by the Shields number. The streams ability to transport large clasts can be assessed using the Costa entrainment velocity, and the critical value for the deposition of large clasts (τb) that may have been mobilized further up stream can be estimated using the O’Connor equation. The values assessed can ultimately offer insight into stream power or the energy available for sediment transport and
