Kudimaramathu Scheme
Kudimaramathu is a scheme for restoring all the minor irrigation tanks and lakes in Tamil Nadu State, India. This is the program taken up by the Government of Tamil Nadu led by Chief Minister Edappadi K. Palaniswami on 13 March 2017. In April 2022, the Government of India launched a similar water body rejuvenation scheme called the Mission Amrit Sarovar. History In Tamil, ''Kudi'' means 'farmers or people'. ''Maramathu'' means 'repair'. It literally means the maintenance and management of waterbodies by people. It has existed in India even after the British rule. During the summers, as one of the agriculturalists, they worked to deepen and widen the lakes, streams, ponds, canals and drains which are the sources of agricultural irrigation and drinking water. They also repair damaged sluices. This work of citizens is called 'Kudi maramathu' (civic work). After the lakes etc. After Water resources like lakes, ponds were taken over by the Tamil Nadu Public Works Department in indep ...

Tamil Nadu
Tamil Nadu (; , TN) is a state in southern India. It is the tenth largest Indian state by area and the sixth largest by population. Its capital and largest city is Chennai. Tamil Nadu is the home of the Tamil people, whose Tamil language—one of the longest surviving classical languages in the world—is widely spoken in the state and serves as its official language. The state lies in the southernmost part of the Indian peninsula, and is bordered by the Indian union territory of Puducherry and the states of Kerala, Karnataka, and Andhra Pradesh, as well as an international maritime border with Sri Lanka. It is bounded by the Western Ghats in the west, the Eastern Ghats in the north, the Bay of Bengal in the east, the Gulf of Mannar and Palk Strait to the south-east, and the Indian Ocean in the south. The at-large Tamilakam region that has been inhabited by Tamils was under several regimes, such as the Sangam era rulers of the Chera, Chola, and Pandya c ...

Sediment Basin
A sediment basin is a temporary pond built on a construction site to capture eroded or disturbed soil that is washed off during rain storms, and protect the water quality of a nearby stream, river, lake, or bay. The sediment-laden soil settles in the pond before the runoff is discharged. Sediment basins are typically used on construction sites of or more, where there is sufficient room. They are often used in conjunction with erosion controls and other sediment control practices. On smaller construction sites, where a basin is not practical, sediment traps may be used. Essential sediment abundance is prevalent in the construction industry which gives insight to future endeavors. On some construction projects, the sediment basin is cleaned out after the soil disturbance (earth-moving) phase of the project, and modified to function as a permanent stormwater management system for the completed site, either as a detention basin or a retention basin. Sediment trap A sediment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tank Cascade System
The tank cascade system, or ''wewa-ellangava'' system, is an ancient Sri Lankan irrigation infrastructure. The system is a network of small tanks draining to large reservoirs that store rainwater and surface runoff for later use. Originating in the 1st millennium BCE, the system was designated a Globally Important Agricultural Heritage System by the United Nations Food and Agriculture Organization in 2017. Centralized bureaucratic management of large-scale systems was implemented from the 3rd to the 13th centuries. Geography The tank cascade system is largely located in the semi-arid north-central section of the island, which experiences equatorial heat, limited freshwater, and erratic rainfall patterns. Minimal groundwater storage capacity, high evaporation, and low or variable precipitation thanks to the monsoon cycle "in this hard rock region meant that no stable human settlement would have been possible without recourse to the storage of surface water in small tanks."

Mission Kakatiya
Mission Kakatiya ("Our Village Our Lake") is a scheme for restoring all the minor irrigation tanks and lakes in Telangana State, India. This scheme aims to renovate 46,531 tanks and lakes, storing 265 TMC water across the state in five years. This is the first program to be taken up by the Government of Telangana after coming into power in June 2014. The tanks and lakes are dug to remove silt for increasing water storage capacity. The household agricultural income has also increased by 78.50% in the tank ayacut area. In April 2022, the Government of India launched a similar water body rejuvenation scheme called the Mission Amrit Sarovar. History The agriculture was solely depended on the tanks. Until the Nizam rule, the tanks had a capacity of 244 TMC in Telangana region, but due to negligence most of it was lost. The irrigated land (ayacut) under 70,000 tanks in 1956 was around 25 lakh acres. By 2014 the tanks left were 46,531, nearly half of them were dry. The farmers start ...

Water Table
The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as ...

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting i ...

Alluvial Soil
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culverts
A culvert is a structure that channels water past an obstacle or to a subterranean waterway. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. In the United Kingdom, the word can also be used for a longer artificially buried watercourse. Culverts are commonly used both as cross-drains to relieve drainage of ditches at the roadside, and to pass water under a road at natural drainage and stream crossings. When they are found beneath roads, they are frequently empty. A culvert may also be a bridge-like structure designed to allow vehicle or pedestrian traffic to cross over the waterway while allowing adequate passage for the water. Culverts come in many sizes and shapes including round, elliptical, flat-bottomed, open-bottomed, pear-shaped, and box-like constructions. The culvert type and shape selection is based on a number of factors including requirements for hydraulic performance, limitations on ups ...

Sluices
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] |
Construction
Construction is a general term meaning the art and science of forming Physical object, objects, systems, or organizations."Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 It comes from the Latin word ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To 'construct' is a verb: the act of building, and the noun is construction: how something is built or the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:de ...
