Generally the embankment height is less than 1.5 meters FCD/I schemes Flood control and drainage with or without irrigation schemes. An FCD/I scheme is a system of water management infrastructure comprising flood embankments and networks of internal drainage/irrigation canals that are mostly for drainage purposes but can also be used for irrigation, in particular in the tidal impact areas in the southeast and southwest regions Flood land/ Floodplains Areas of relatively low-lying lands, seasonally inundated by overspill from adjacent rivers, lakes, reclaimed from a body of water and natural depressions Gher Low land used for culture fisheries, especially for shrimp culture in coastal areas Integrated pest management (IPM) In the integrated pest management approach, each crop and its measured pests are considered as an ecological system, and a control program that integrates a variety of biological, chemical, and cultural methods in proper sequence and timing, is developed Khal Natural channel Kharif I Early summer (March through June) Kharif II Late summer (July through October) Kachcha Toilet A temporary, unhygienic, indigenous latrine made of bamboo Khas land Unoccupied land that is legally owned by the Government, including accredited land from rivers Pukkha toilet A permanent hygienic sanitary latrine with concrete ring slab, covered with permanent shades PWD A survey datum being used by the public works department for all topographic survey works Regulators The regulating structures required to control the flow of water into and outside the project area Resectioning With reference to an embankment, rebuilding the damaged embankment to its design section Temporary desilting basin A small low-lying area to accumulate runoff silt from a construction site Thana/Upazila Subdistrict Union Subdivision of a subdistrict CONTENTS MAPS ii I.
