Sediment

The purpose of the stream table investigation was to investigate the variables that influence erosion rates in a stream. Sediments that were eroded at or near Linganore High School end up in the Chesapeake Bay. Sediments eroded from rocks in Linganore Creek and are carried to the Monocacy River. From there, the sediments are taken to the Potomac River. The Potomac River’s water and anything loose in it are dispensed into the Chesapeake Bay. Water transports the material from Linganore to the Chesapeake Bay. Erosion is the process of rock being worn away by the action of water, wind, and other processes. The three types of rock that erosion can impact are igneous, metamorphic, and sedimentary. Sedimentary Rocks are formed by eroded pieces…

To estimate average annual volume of runoff and sediment loads entering in Mula Dam reservoir 4. Major scientific fields of interest Application of the study: 1. It is needed for sustainable natural resource development and regional planning. 2. It will help to identify vulnerable areas to soil erosion and how it can be survived through work as contour bunding, check dam, tree plantation (those which survive in the particular geo-climatic conditions). 3. The application of the results will be…

Erosion is the geological process in which Earth's surface is worn down by natural forces like running water, wind, glaciers and waves. Erosion is a key factor in the formation of beaches because erosion moves sediment (sand) from one location to another. There are three major types of coastal erosion; hydraulic action, corrosion and corrosion. Hydraulic action is when waves crashing against a headland causes erosion. Waves enter cracks in the rock and air is compressed into the crack by the…

The Spit is the longest in the country, reaching 25 km in length. (DEPARTMENT OF CONSERVATION, (n.d)). The Maori name for Farewell Spit is Onetahua which gives an accurate description of what the spit is; heaped up sand. (100% pure New Zealand, (n.d)). The spit is thought to have started forming 14,000 years ago at the end of the ice age. The spit originally started from the sediments in the fast short flowing rivers of the Southern Alps. These sediments, in times of flood, stain the Tasman Sea…

observations that i was going to form including the sediment, the marine organisms, and the human impact of the beach. Sediment Transport My first observation was the first thing my feet touched when i got to the beach, the sand! The sand in ocean city is of a yellow tone and starts out as bumpy because of all of the rocks and twigs then softens out. The beach is constructed by sediments spread throughout the coastline that have been transported by waves and currents. ( Sverdrup and Kudela,…

southern coast until part of Avalon called the Carolina Terrane hit the southern part. These collisions caused the rocks to be metamorphosed. North America and Baltica at this time were located near the equator and North America was moving north into the position it is located in today. The other continents were starting to come together and create another super continent. The Catskill Delta was the delta that carried the Acadian Mountain sediments into the western inland sea. This delta…

The discharge of a stream in the total volume of water passing a point along the bank in a second. Most streams are turbulent, meaning that their water swirls in complex patterns. 5. Water meets friction and moves extra slow than at the surface near the middle of the stream. 6. Streams erode the landscape by scouring, lifting, abrading, and dissolving. The resulting sediment provides dissolved loads, suspended loads, and bed loads. The total quantity of sediment carried by a stream is its…

Arches National Park This area is changing and here is why. The story of Arches begins roughly 65 million years ago. At that time, the area was a dry seabed spreading from horizon to horizon. The striking red rock features we see today would have been buried thousands of feet below you, raw material as yet uncarved. Then the landscape slowly began to change due to erosion (National Park Service). The national park lies on top of an underground evaporite layer or salt bed, which is the main…

Sequence of Karoo sediment has been determined in the lake with the possibility of being the source rock or reservoir, succeeded by post Karoo Mesozoic reservoir rock and capped by Miocene. The sediments thickness in the northern part is greater than 2 km with the bottom of the lake revealing organic sediments in highly anoxic conditions. Despite similarities in the overall stratigraphy in the half graben basins each is filled differently and source rock in each half graben is determined once…

These tests were commissioned by the Environmental Protection Agency (EPA) in response to a proposed chemical plant being built over an important groundwater supply. This report will summarize the finding of the potential damages of a chemical spill and attempt to address how in the event of a chemical contamination in the groundwater should be dealt with. The proposed site for the chemical plant is divided into five different layers of sediments that vary in grain size and thickness. Layers…
