Abstract
India, being a tropical country, most of the rivers flow during monsoon only. The quantity of water available in river channels to meet various water demands (particularly irrigational) reduces marginally once monsoon surpasses. Therefore, to make perennial availability of water in river channels, check dam technology and water storage techniques are under practice. The K. T. Weir technology, a part of above-mentioned techniques emphasizes on water storage by using steel plate needles conventionally. With the reference of effectiveness of FRP needles over M. S. Needles, this paper reviews the use of modern FRP needles over conventional steel plate needles, their design specifications, manufacturing, installation, working, maintenance, durability and cost effectiveness in pocket irrigation schemes. This paper also includes a case study of FRP needles installation in check dams of Odisha state.
