KRISHNA 2011 the Difference Between a Canal and a River The difference between a canal and a river | GroundReport http://www.groundreport.com/article.php?articleID=2938545&action=pri... Submitted by: Madugundu Krishna April 25, 2011 The difference between a canal and a river The difference between a canal and a river is that a river is the work of nature, and a canal is a channel for water made by men. Canals, or water-channels, have been made by men for two different purposes. Some have been made for the purpose of carrying goods by boats and ships from one place to another. In England, which, being a cold and rainy country, does not need canals for irrigation, canals were made before the days of railways for this purpose. In those days the roads were few and bad, and the cost of sending heavy goods by carts was great; but when these canals were made, such goods could travel much more cheaply from town to town in barges and boats when the steam- engine was invented and railways were made, these canals went a good deal out of use, because goods could be sent much more quickly by rail; but they are still used for heavy goods, like bricks, when there is no hurry, because such things can go much more cheaply by canal than they an by rail. There are also two famous sea-canals for the passage of ships-the Suez Canals and the Panama Canal. By the former, ships from Europe can come straight to India instead of having to go right round Africa; and by the Panama Canal, the Atlantic and Pacific Oceans are connected. In India, canals have been made mainly for irrigation. North India is a dry area, and depends for its harvests on the monsoon, which is uncertain. If the monsoon fails, the crops die for lack of rain, and there is famine. And yet there is plenty of water, which runs away in the rivers uselessly to the sea. But by the wonderful irrigation system of Punjab, a great deal the water of these rivers is spread over the lad by a network of canals. In the Punjab alone, over ten million acres are watered by these canals. These canals brought great wealth to Punjab, and turned whole desert into fertile farms.

  • Lesson 4: Sediment Deposition and River Structures
    LESSON 4: SEDIMENT DEPOSITION AND RIVER STRUCTURES ESSENTIAL QUESTION: What combination of factors both natural and manmade is necessary for healthy river restoration and how does this enhance the sustainability of natural and human communities? GUIDING QUESTION: As rivers age and slow they deposit sediment and form sediment structures, how are sediments and sediment structures important to the river ecosystem? OVERVIEW: The focus of this lesson is the deposition and erosional effects of slow-moving water in low gradient areas. These “mature rivers” with decreasing gradient result in the settling and deposition of sediments and the formation sediment structures. The river’s fast-flowing zone, the thalweg, causes erosion of the river banks forming cliffs called cut-banks. On slower inside turns, sediment is deposited as point-bars. Where the gradient is particularly level, the river will branch into many separate channels that weave in and out, leaving gravel bar islands. Where two meanders meet, the river will straighten, leaving oxbow lakes in the former meander bends. TIME: One class period MATERIALS: . Lesson 4- Sediment Deposition and River Structures.pptx .

Background, Rationale and Outputs/Results Expected: According to Richard Haggerty’s country study on Haiti from 1989, in 1925, 60% of Haiti’s original forests covered the country. Since then, the population has cut down all but an estimated 2% of its original forest cover. The fact that many of Haiti’s hillsides have been deforested has caused several flooding problems for cities and other communities located in critical watershed and flood-plain areas during recent hurricane seasons. The 2008 hurricane season was particularly devastating for Haiti, where over 800 people were killed by four consecutive tropical storms or hurricanes (Fay, Gustav, Hanna, and Ike) which also destroyed infrastructure and caused severe crop losses. In 2004, tropical storm Jeanne killed an estimated 3,000 people, most in Gonaives.

  • Canal and River Bank Stabilisation for Protection Against Flash Flood and Sea Water Intrusion in Central Vietnam
    CANAL AND RIVER BANK STABILISATION FOR PROTECTION AGAINST FLASH FLOOD AND SEA WATER INTRUSION IN CENTRAL VIETNAM V. Thuy1, I. Sobey2 and P. Truong3 1 Department of Agriculture and Rural Development, Quang Ngai, Vietnam 2Kellog Brown Roots, Quang Ngai Natural Disaster Mitigation Project [email protected] 3 TVN Director and East Asia and South Pacific Representative, 23 Kimba St, Chapel Hill, Brisbane 4069, Australia [email protected] Abstract Quang Ngai, a coastal province in central Vietnam, is prone to flash flood caused by high annual rainfall, with 70% (2300mm/yr) falling over three months and steep terrain resulting in high velocity water flows. This often leads to flash floods in mountainous areas and large scale flooding in low-lying areas. The high velocity flows and flooding cause severe erosion on dike, canal and river banks built to protect farm land from flooding in the rain season and sea water intrusion in the dry season. Therefore the stability of these measures provides the local community a protection against flash flood and sea water intrusion at the same time. Both vegetative measures and hard structures such as rock and concrete have been used in the past to protect these banks, but they are ineffective partly due to the local sandy soils used to build them and partly to the strong current. Although vetiver grass has been used very successfully for flood erosion control in the Mekong Delta of southern Vietnam, where flow velocity is relatively slow, it has not been used under very strong current. As a last resort, vetiver grass was tested for its effectiveness in protecting the banks of these rivers and canals.

  • SOLICITOR's SEARCHES This Note Sets out Useful
    SOLICITOR’S SEARCHES This note sets out useful background information regarding the nature of enquiries with which Canal & River Trust can assist, the fees that are payable in respect of such enquires and other general information that may be of assistance to you. The Trust cares for a 2,000 mile network of canals and rivers. Most of the Trust’s structures are well over 200 years old and the canals themselves are constructed in a variety of ways. Some are natural rivers which are not owned by the Trust but where we are the navigation authority. The Trust also manages a significant portfolio of property that includes operational boat yards, docks, historic warehouses, cottages, marinas, industrial estates and development land across England and Wales. Every precaution must be taken to avoid the risk of removing Trust’s right of support, breaching the waterway damaging any of the waterway structure, as this may result in extensive flooding, with damage to buildings, property, services and possible loss of life. Embankments and other waterway structures are particularly vulnerable and no excavation, landscaping, or any other work or activity should take place near to, or at the foot of an embankment or waterway structure without consulting the Trust, even though such works may not be on Trust’s property. Except where they are expressly reserved for the benefit of the property, rights such as mooring, fishing, discharges to, or abstraction from, the waterway, and any encroachment upon or projection over the waterway require the written consent of the Trust and in some circumstances, that of the other organisations such as the Environment Agency.
