Present status of irrigation in bd
Irrigation is an artificial water supply for agricultural land. In Bangladesh, irrigation water comes from surface water sources like canals, pumps, and traditional methods, as well as groundwater sources like deep tube wells, shallow tube wells, and hand tube wells. Currently about 36.9 million hectares of land are irrigated in Bangladesh, though irrigation is available to less than half of land that could be irrigated. Common irrigation projects in Bangladesh include the GK project, Tipaimukh Dam, Chandpur Irrigation Project, and Barrindra Irrigation Project. The most common irrigation methods are basin, border, and furrow methods. With improved management, irrigation could be expanded to water 4-5 million additional hect
Irrigation systems in bangladesh
The document discusses irrigation systems used in Bangladesh. It describes how irrigation has been widely used for thousands of years in dry regions to supply water for agriculture. In Bangladesh, both shallow and deep tube wells are commonly used to irrigate fields during the dry season from November to March. The two main categories of irrigation devices used are motorized pumps (like deep tube wells and shallow tube wells) and manual pumps. Modern irrigation techniques like drip irrigation are more efficient but also more costly than traditional surface irrigation methods. The selection of an appropriate irrigation method depends on factors like soil, climate, water source and costs.

indus basin and salient fatures of barrages and link canals in pakistan
The document discusses Pakistan's Indus Basin Irrigation System, which diverts around 74% of annual river flows into its extensive canal network, while the rest flows into the sea or is lost in the river system. However, the irrigation system has very low efficiency, with 53% of water (55 MAF) lost during conveyance through canals and field channels, resulting in an overall conveyance efficiency of just 47%. Improving the efficiency of the irrigation system and reducing the large amounts of water lost during conveyance could help address water scarcity issues.

Environmental aspects of sardar saroar project
The document summarizes the environmental aspects and impacts of the Sardar Sarovar Project on the Narmada River in India. The project involves building a large dam and irrigation system across three states. It will submerge over 37,000 hectares of land and displace over 100,000 people across 245 villages. While the project aims to provide irrigation, it has faced significant opposition for its environmental and social impacts, including loss of homes, livelihoods and increased health issues for displaced communities.
Ganga proposasl for national river
The document discusses concerns about hydroelectric projects along the Ganga River between Gangotri and Uttarkashi in India. It notes that several projects have been proposed or built that divert water from the river into tunnels, sometimes for over 100 km. This denies people access to the river and is altering the river's ecology and water quality close to the source. The document calls for stopping existing projects, releasing more water from dams, and maintaining the natural flow of the Ganga without diversions or obstructions to preserve its religious and cultural significance.
Indus basin irrigation system by Engr. Faiz Rahimoon
The Indus Basin Irrigation System (IBIS) is the largest contiguous irrigation system in the world, irrigating 45 million acres of farmland in Pakistan. It comprises dams, barrages, canals and tube wells built after the 1960 Indus Waters Treaty between India and Pakistan. While providing food security and economic benefits, the IBIS faces challenges of waterlogging and salinity from lack of drainage. Improving irrigation efficiency and adopting new agricultural practices can help address these issues.
Sabarmati riverfront development
The Sabarmati Riverfront Development project in Ahmedabad achieved several objectives: 1) It converted the polluted and neglected Sabarmati River into an asset by keeping it filled with water and eliminating pollution. 2) It created large civic spaces along the riverbanks for public recreation. 3) It established an institutional body to oversee planning and implementation. 4) It created a new landmark announcing Ahmedabad's arrival as a world-class city. However, some argue the project disrupted the river's natural ecology by straightening banks and reducing it to a narrow canal. There are also concerns about whether filling the river can be sustained given potential impacts of climate change.

The document discusses the Indian River-linking Project which aims to transfer water from surplus river basins in northern and northeastern India to water-deficit areas in the south and west through a network of 30 links and canals spanning 14,900 km. The multi-billion dollar project is proposed to provide irrigation, flood control, hydropower and regional development benefits. However, critics argue it will be extremely costly, displace millions of people, degrade downstream environments, and not consider interests of upstream states like Nepal. There are also doubts about the feasibility of large-scale inter-basin water transfers and effectiveness of building more dams.
Mithi river pollution pptx.
The Mithi River in Mumbai is heavily polluted and acts as an open sewer. During monsoons, overflow from lakes contributes additional sewage flow down the 17.83 km river before it empties into the Arabian Sea. Large parts of Mumbai were built on reclaimed land from the sea and rivers, including filling in the Mithi River estuary. This land reclamation has adversely impacted the city's ecology and contributed to flooding issues. The devastating 2005 floods in Mumbai that killed over 1000 people resulted from the narrowed Mithi River being unable to handle heavy monsoon flows due to development and reclamation along its path.

It notes that irrigation has been used in India for thousands of years, with references found in ancient scriptures and the Indus Valley Civilization utilizing wells and canals. A major early irrigation work was the Grand Anicut constructed in the 2nd century CE in South India. During the medieval period, irrigation expanded through construction of canals, dams, and bunds. Under British rule, major irrigation systems were built including the Upper Ganga and Godavari Delta canals. Since independence, the government has undertaken programs and projects to expand irrigation coverage and modernize systems using techniques like drip irrigation.

Irrigation involves supplying water to plants through artificial means to supplement rainfall and soil moisture. There are several methods of irrigation used in Bangladesh depending on soil, topography, water availability, and crop type. The main methods described include flood, check basin, border strip, furrow, and basin irrigation. Drainage is the artificial removal of excess water from crop fields and is important to improve soil structure and productivity by preventing waterlogging. The hydrologic cycle describes the natural circulation of water on Earth through evaporation, condensation, precipitation, and both surface water and groundwater flow. Proper soil structure and texture are also important for irrigation and drainage as they determine water and air flow in the soil.

BMDA
The document provides an overview of the Barind Multipurpose Development Authority (BMDA). Some key details include:
- BMDA was established in 1992 to oversee agricultural development projects in 6 districts of Rajshahi division.
- It has implemented various irrigation, afforestation, rural infrastructure and drinking water projects.
- Some of the major projects include installing over 14,820 deep tube wells for irrigation, re-excavating 1,537 km of canals and ponds, and planting over 2.7 crore trees.
- These projects have helped increase crop yields, reduce temperatures, and improve livelihoods in the Barind area.
rain water harvesting
This document discusses the importance of rainwater harvesting. It notes that fresh water is becoming scarce globally and that traditional water management systems need reviving. It defines rainwater harvesting as the conscious collection and storage of rainwater for drinking, domestic, and irrigation purposes. Benefits include arresting groundwater decline, augmenting aquifers, and conserving surface runoff. Methods discussed are surface runoff harvesting through storage tanks or groundwater recharge, and rooftop rainwater harvesting through storage tanks or recharge. Key components and economics of systems for individual homes and buildings are covered. The conclusion stresses the need to sustain groundwater by judiciously catching rainwater wherever possible.
Ground water recharge Methods
This document discusses methods of groundwater recharge. It is divided into two parts: natural recharge and artificial recharge. Natural recharge occurs when rainwater enters the soil through pores and fractures. Artificial recharge is necessary when natural recharge cannot meet water demands. Methods of artificial recharge include spreading methods like flooding, basins, and channels; injection methods using wells and galleries; and induced recharge by lowering the water table before monsoon season. The document provides details on various artificial recharge techniques and factors to consider for each method.
Water resources and irrigation scenario of India.pptx
1) India has significant water resources from rivers, lakes, groundwater aquifers, and annual precipitation. However, the distribution of water is highly variable spatially and temporally.
2) Agriculture accounts for the majority (69%) of water usage in India, relying heavily on irrigation. Both surface water and groundwater are used for irrigation.
3) Major issues facing irrigation in India include an aging infrastructure, increasing siltation of dams, and increasing water demand from a growing population. Improving water management through initiatives such as PMKSY will be important for sustainable water usage.
