A large number of Indian Standard (IS) codes are available that are meant for virtually every aspect of civil engineering one can think of. During one's professional life one normally uses only a handful of them depending on the nature of work they are involved in. Civil engineers engaged in construction activities of large projects usually have to refer to a good number of IS codes as such ...
Subsurface Textile Irrigation (SSTI) is a technology designed specifically for subsurface irrigation in all soil textures from desert sands to heavy clays. The use of SSTI will significantly reduce the usage of water, [1] fertilizer and herbicide. It will lower on-going operational costs and, if maintained properly, will last for decades.
The non-limiting water range (NLWR) represents the range of water content in the soil where limitations to plant growth (such as water potential, air-filled porosity, or soil strength) are minimal. John Letey (1985) from UC Riverside introduced the NLWR concept in an attempt to integrate several physical properties associated with plant or root ...

Minor irrigation project is a classification of irrigation projects used in India. A project with a designed to irrigate an area of 2000 hectares or less is classified as a minor irrigation [ 37 ] [ 38 ] [ 39 ] Before the Fifth Five-Year Plan , irrigation schemes were classified on the basis of investments needed to implement the scheme.

The old Sardar canal project in the state of Gujarat, India, was designed with an irrigation intensity of 32%, but at the upstream part the delivery was at an intensity of 42% (i.e. 131% of the design norm) and at the downstream end it was only 19% (i.e. 59% of the norm), although the project aimed at protective irrigation with equal rights for ...
It has been declared as National Irrigation Project by Government of India. The project involved, Gose Khurd Dam along with the network of water canals including 99 km long right bank canal, 22.93 km left bank canal, lifting stations at Akot, Ambhora, Mokharbardi, Nerla and Tekepar.
Dryland farming caused a large dust storm in parts of Eastern Washington on October 4, 2009. Courtesy: NASA/GSFC, MODIS Rapid Response [1]. Dryland farming has evolved as a set of techniques and management practices to adapt to limited availability of water, as in the Western US and other regions affected by climate change for crops such as tomato and maize.
