Silt

developed and grew along the Huang He, Chang Jiang, Wei and Luo rivers Things like rivers, mountains and deserts benefitted the development. Yet in other ways, they restricted China as well. Rivers flooded causing destruction but also leaving behind silt. Mountains helped protect the people in China from any invasion Deserts were very dangerous to pass through. They provided borders that kept the Chinese isolated from the rest of the world. The deserts protected just as the mountains did.…

The Nile River flows north through Egypt and empties into the Mediterranean Sea. The Nile River acts as a natural highway for travel through Egypt. The Nile also floods annually which provides rich silt deposits that are perfect for farming. Therefore, life in Egypt was built upon the Nile. Egyptians would farm the rich fertile land around the Nile, therefore they would build their homes on the edge of the fertile land in order to leave more room…

The US Geological Survey tested the performance and effectiveness of the Basins in 1969. Their study analyzed data gathered from three basins located in both Nassau and Suffolk county. All three basins had different shapes and drainage area sizes in order to determine an average performance from all the systems. To determine the effectiveness, the basins were analyzed in three different areas: Precipitation-Inflow relation, Runoff Hydrograph, and Rates of Filtration. The three basins analyzed…

Invasive species have the potential to have a dramatic, negative impact on the areas that they invade. This can be observed in the harm that they cause to the environment and their impact on the health of humans and other animals. Arguably, invasive species cause the most damage by contributing to the loss of other species’ habitats. Many of the endangered plant and animal species found in the United States are in this position, in part, because of the impact of invasive species on their habitat…

A nation’s capability to adapt to its terrain and to utilize its natural resources is often critical in determining the ability people to survive in its land. This was evident in numerous successful ancient civilizations like the Egyptian civilization, organized around the Nile River, which ruled from 3200-1640 BCE. To the south, and a few millennia later, the Aksum Empire adapted to its mountainous terrain and long seacoast to dominate trade and agriculture from 100-750 CE. Just before the…

started as independent cities and then became city-states. The land was rich, but was hard in the summer time. In spring, the rivers would flood and irrigate the fields. The riverbed was unstable and would flood at unexpected times. The river would carry silt down stream, which would help fertilize the land…

The Ercall Quarries were visited on October 21st, 2017. It is an important geological site and is part of the Site of Special Scientific Interest (SSSI). The Ercall sometimes known as the Ercall Hill, is a small hill in the county of Shropshire, England. The site includes 540-million-year-old ripple beds and ancient pre-Cambrian lava flows in exposed quarries. There is a M54 motorway near the Quarries, giving it easy access to the Quarries. The motorway was constructed in 1974, near the northern…

1.1 Introduction to Landslide A landslide is a geological phenomenon, which includes a wide range of ground movements, such as deep or shallow failure slopes and rock falls. See figure 1.1. 1.1.1 Factors influence Landslides Landslides occur when the stability of the slope turns from the stable state to unstable state. Most of the Landslides usually cause depend on two main factors: (i) Natural Factors and (ii) Anthropogenic Factors. (USSG, 2004) (i) Natural Factors (a) Geological…
