Giant's Tank
Giant's Tank ( ta, கட்டுக்கரை குளம், translit=Kaṭṭukkarai Kuḷam; si, යෝධ වැව ''Yōdha Væva'') is an irrigation tank in northern Sri Lanka, approximately south east of Mannar. History Some historians have speculated that Giant's Tank is the same as the Mahanama Matha Vapi tank built by King Dhatusena in the fifth century and restored by King Parakramabahu I in the twelfth century. On the other hand, Mudaliyar C. Rajanayagam in his book ''Ancient Jaffna'' suggests that the tank was probably constructed by the Nagas. Rajanayagam has suggested that the ''Megisba'' lake mentioned by Pliny in ''Description of Taprobane'' was in fact Giant's Tank. Consideration was given to renovating the tank during Dutch Governor Willem Jacob van de Graaf's administration in the eighteenth century but nothing happened. Restoration did however begin in the 1880s following a motion in the Legislative Council by P. Ramanathan. Delays by epidemics and ...

Legislative Council Of Ceylon
The Legislative Council of Ceylon was the legislative body of British Ceylon, Ceylon (now Sri Lanka) established in 1833, along with the Executive Council of Ceylon, on the recommendations of the Colebrooke-Cameron Commission. It was the first form of representative government in the island. The 1931 Donoughmore Constitution replaced the Legislative Council with the State Council of Ceylon. Members of the Legislative Council, used the post-nominal letters, MLC. History Introduction In 1833 the Colebrooke-Cameron Commission created the Legislative Council of Ceylon, the first step in representative government in British Ceylon.

Irrigation Tanks In Sri Lanka
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the oldest form of irrigation ...

Sluice
Sluice ( ) is a word for a channel controlled at its head by a movable gate which is called a sluice gate. A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a River Sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. They are also used in wastewater treatment plants and to recover minerals in minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-channel Flow
In fluid mechanics and hydraulics, open-channel flow is a type of liquid flow within a conduit with a free surface, known as a channel. The other type of flow within a conduit is pipe flow. These two types of flow are similar in many ways but differ in one important respect: open-channel flow has a free surface, whereas pipe flow does not. Classifications of flow Open-channel flow can be classified and described in various ways based on the change in flow depth with respect to time and space. The fundamental types of flow dealt with in open-channel hydraulics are: * Time as the criterion ** ''Steady flow'' *** The depth of flow does not change over time, or if it can be assumed to be constant during the time interval under consideration. ** ''Unsteady flow'' *** The depth of flow does change with time. * Space as the criterion ** ''Uniform flow'' *** The depth of flow is the same at every section of the channel. Uniform flow can be steady or unsteady, depending on whether or not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TamilNet
TamilNet is an online newspaper that provides news and feature articles on current affairs in Sri Lanka, specifically related to the erstwhile Sri Lankan Civil War. The website was formed by members of the Sri Lankan Tamil community residing in the United States and publishes articles in English, German and French. It is Tamil nationalist and is described as a pro rebel LTTE website. It is a news site that is relied upon by journalists, civil society and the diplomatic community both within Sri Lanka and globally to seek out the LTTE leadership's perspective on the civil conflict. Tamilnet and non-governmental organizations such as Free Media Movement (FMM), Committee to Protect Journalists (CPJ) and ARTICLE 19 confirm that the website is currently banned in Sri Lanka. Operations Tamilnet was founded by Muthuthamby Sreetharan, a graduate of Hartley College and native of Karaveddy, Jaffna and Jeyachandran Kopinath. Kopinath functions as the main editor from Norway.

Tamil Language
Tamil (; ' , ) is a Dravidian language natively spoken by the Tamil people of South Asia. Tamil is an official language of the Indian state of Tamil Nadu, the sovereign nations of Sri Lanka and Singapore, and the Indian territory of Puducherry. Tamil is also spoken by significant minorities in the four other South Indian states of Kerala, Karnataka, Andhra Pradesh and Telangana, and the Union Territory of the Andaman and Nicobar Islands. It is also spoken by the Tamil diaspora found in many countries, including Malaysia, Myanmar, South Africa, United Kingdom, United States, Canada, Australia and Mauritius. Tamil is also natively spoken by Sri Lankan Moors. One of 22 scheduled languages in the Constitution of India, Tamil was the first to be classified as a classical language of India. Tamil is one of the longest-surviving classical languages of India.. "Tamil is one of the two longest-surviving classical languages in India" (p. 7). A. K. Ramanujan described it as "the on ...

Catchment Area
In human geography, a catchment area is the area from which a location, such as a city, service or institution, attracts a population that uses its services and economic opportunities. Catchment areas may be defined based on from where people are naturally drawn to a location (for example, labour catchment area) or as established by governments or organizations for the provision of services. Governments and community service organizations often define catchment areas for planning purposes and public safety such as ensuring universal access to services like fire departments, police departments, ambulance bases and hospitals. In business, a catchment area is used to describe the influence from which a retail location draws its customers. Airport catchment areas can inform efforts to estimate route profitability. Types of catchment areas Catchments can be defined relative to a location and based upon a number of factors, including distance, travel time, geographic boundaries or popu ...

River Mouth
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.
