Why is flooding prone to Bangladesh? Bangladesh suffers from regular and extreme flooding for the following reasons‚ first being that its one meter above sea level‚ as well as it being a LEDC meaning it’s a less economical developed country. The rivers leading from the Himalayas flow into the sea‚ when they suffer with heavy rain the excess water starts to over flow and flood and waterlog land and surroundings. The physical causes are‚ the monsoon climate brings very heavy rain and snow‚ and soils

Mass wasting is defined as the down slope movement of rock and regolith near the Earth’s surface mainly due to the force of gravity. Rock slides and debris slides result when rocks or debris slide down a pre-existing surface‚ such as a bedding plane‚ foliation surface‚ or joint surface. On February 17‚ 2006 the Philippines was hit by landslides. In Southern Leyte mudslides destroyed the mountain village (Barangay) Guinsaugon. During schooltime between 9 a.m. and 10 a.m.‚ an elementary school was

Mass Movements and Their Human Impacts Mass Movement is defined as the down slope movement of rock and regolith near the Earth’s surface mainly due to the force of gravity. Mass movements are an important part of the erosional process‚ as it moves material from higher elevations to lower elevations where transporting agents like streams and glaciers can then pick up the material and move it to even lower elevations. Mass movement processes are occurring continuously on all slopes; some act very

A river changes as you move from the source to the mouth (downstream)‚ but also from bank to bank (across stream). In this essay I will be discussing how depth velocity and bedload size change downstream and across stream linking to past river theory (the Bradshaw method). Depth is defined as the distance between the surface of the river to the bottom (the river bed) this distance is measured in a straight vertical line. As you move from the source to the mouth the river depth increases. (which

Geography Rivers 1. The speed and volume of a river varies from place to place along a river’s course because of many reasons. In the upper course‚ the volume of water is low as there are few tributaries. In comparison‚ the volume of water in the middle course is higher as there are more tributaries supplying water to the main river channel. The volume of water in the lower course is the highest as the lower course has the most tributaries. However‚ many other factors will also affect the

Soil erosion is a major concern in the southeastern region of Nigeria due to high population densities and farming techniques‚ which has resulted in the presence of numerous gullies. While gullies are found all around the world‚ the existence of gullies in Nigeria is regarded as one of the worst environment disasters‚ having negative implications on the environment and the quality of life for humans and other species (Adetona & Ezezika‚ 2011; Ajaegwu & al‚ 2010). Large quantities of soil in Nigeria

Explain how the processes of weathering‚ erosion‚ transportation and deposition have shaped New Zealand. New Zealand is an amazing Ever-changing land‚ full of natural wonders. But there is more to our country than this‚ much more‚ because our country is unique on Earth. Four and a half billion years have made it a country of extraordinary landforms‚ through four main processes. These processes are called weathering‚ erosion‚ transpiration and deposition. As well as our environment and physical shape

Wildcat Creek begins just east of Kokomo in Greentown and ends at the Wabash River in Lafayette. Wildcat creek is about 84 miles long. This creek consists of three different forks‚ the north fork‚ south fork‚ and middle fork. Each fork flows in a general east-west direction. On our field trip‚ we visited the south fork. This stream runs through many different types of land typography‚ such as cropland and forests as well as developed areas. There were many different types of rocks present along this

Describe and explain how river processes change along the long profile of a river A river changes shape as it flows from its source (where a river starts) to its mouth (where a river flows into a sea or lake). The shape of the long profile (a slice through the river from source to mouth) shows how the rivers gradient‚ height‚ energy and load changes due to erosion processes such as abrasion‚ cavitation‚ attrition‚ hydraulic action and corrosion as well as how the rivers deposition rates fluxuate

Stretches of a river can be different in terms of their processes and landforms. Introduction: My investigation is a study of hydrology‚ as I want to find out how and why a rivers channel‚ flow and valley characteristics change as you move downstream from its upper course to its mouth. These changes are represented in the Bradshaw Model (fig 1)‚ a fluvial model that describes changes in the river channel and flow characteristics between different courses along the river. Based on three factors
