Agril Engineers in CAD (Command Area Development)in Odisha

-


















 The CAD program was introduced in Odisha in 1978.Under this scheme, both  micro field channels & drains were constructed in all canal irrigated fields of Major & Medium  irrigation projects of the state.Previously brick line channels were constructed whose longevity was less but now 4 inch thick  RCC Line Channels are being constructed which will last long & serve the farmers better.As most of the major & medium Irrigation Project canals are now covered with micro CAD channels, presently CAD organization has taken up the Minor Irrigation Projects in the state of Odisha.In most of the States in the country, the CAD work is executed by Civil Engineers of Irrigation Department but in Odisha, Agricultural Engineers construct these channels working in Water resources Department on deployment from Agriculture Department.

At present there are one Chief Engineer post, 5 SE posts, 16 Executive Engineer posts,45 Assistant Ex5ecutive posts,36 Assistant Agricultural Engineer posts,Total 103 posts in the Directorate of CAD & PIM to take up the Engineering activities.

About Odisha Water Resources

Odisha is located on the eastern coast of India.The climate of state is tropical with 1450mm average rainfall.

Surface Water :-Water resources of the State are derived from the annual rainfall in the State. The State receives 230.76 BCM of rainfall in a normal year. Water availability in the State on a 75% dependable basis works out to 95.54 BCM now, which will reduce to 85.89 BCM in future.

Groundwater :- According to the latest assessment, Odisha has annually replenishable ground water resource of 21 BCM (ham), out of which 12 BCM is taken as safe for use. Thus, Average surface and ground water potential of the State is 141 BCM at present which is estimated to reduce to 129 BCM in 2050. (ORISSA STATE WATER PLAN, 2004)

About Odisha Rivers-

Odisha is drained by 11 major rivers and their tributaries, which are clearly separated by high ridges. The north of Mayurbhanj district is drained by Subarnarekha where as the south of the district and parts of Balasore district is drained by Budhabalang River. Districts of Kendujhar and Bhadrak drain into Baitarani. Sundargarh, Debgarh, Angul, Dhenkanal, Jajpur and Kendrapara drain into Brahmani river.Part of Sundargarh, Jharsuguda Sambalpur, Baragarh, Sonepur, Balangir, Nuapara, Cuttack, Jagatsinghpur, Khurda and Puri drain into Mahanadi. Kolab and Indravati drain Nabarangpur, Malkangiri and Koraput districts and Vansadhara and Nagavali drain Rayagara and parts of Gajpati districts. Ganjam is drained by Rushikulya River. In the upper reach of the rivers the slope is steep and there is no problem of drainage. But once the rivers reach the coastal plains the slope flattens and velocity reduces and drainage congestion occurs.

Water Management

 The meaning of water management is optimization of watering a crop as per it's requirement.In coming years we are going to face water stress in many parts of the world where as  to feed the growing population, cultivable land needs to be  increased along with water requirement for Agriculture. Therefore we are to control water while irrigating a crop. We should not allow water for deep percolation and drainage rather supply water up to root zone depth of a crop. We are to harvest each drop of rain water & prohibit it to drain to river & ocean. For example Rice consumes about 4,000 - 5,000 litres of water per kg of grain produced & It takes about  1500 litres  of water to produce 1 kilogram of wheat. Rice is not a aquatic crop: it has great ability to tolerate submergence. By keeping two  inch standing  water in Rice field, we control weeds but cut off sunlight and aeration to the ground. An innovative method called the System of Rice ...
