The Department of Soil and Water Engineering has been established with the College of Agricultural Engineering & Technology in 1984 under Gujarat Agricultural University, Junagadh Campus, Junagadh, one of the four campuses of GAU S K Nagar, Gujarat. In 2004-05, GAU were bifurcated into four universities, among which, Junagadh campus of GAU has come into existence as Junagadh Agricultural University, Junagadh. The Soil and Water Engineering Department under CAET, JAU, Junagadh has been renamed as Department of Soil & Water Conservation Engineering and new Department of Irrigation & Drainage Engineering was established in 2017-18 with the implementations of 5th Dean’s committee recommendations adopted by ICAR, New Delhi. The main aim of the newly established “Department of Irrigation and Drainage Engineering” is to strengthen the Agricultural Engineering faculty to carry out teaching, research and extension activities in the fields of irrigation technologies viz. surface irrigation methods namely border, furrow, surge irrigation etc., MISs namely Drip, Sprinkler Mini sprinkler, Micro sprinkler, Subsurface drip/oozing pipe, Rain gun irrigation, fertigation schedules of various crops etc, groundwater, water conveyances, pumping machineries as well as surface/subsurface drainage systems. Keeping this in view, it is aimed to generate skilled manpower in the field of irrigation and drainage engineering to cater the needs of farmers, NGOS, line departments, industries as well as organizations by imparting educations through the B. Tech., M. Tech. and Ph. D. programmes. The top priority is to raise the standard of UG and PG education and research in the field of Irrigation and Drainage Engineering.

Recommendations / Technology developed
1.
Identification of potential groundwater recharge zones in ozat river basin It is recommended to the Farmers, NGOs and Government line departments that the Ozat river basin is divided in to five groundwater potential recharge zones namely excellent, good, moderate, poor and very poor having an area of 220.14 km2 (6.93%), 2094.81 km2 (65.95%), 430.05 km2 (13.54%), 430.87 km2 (13.57%) and 0.36 km2 (0.01%) respectively.
2.
Cotton crop response to drip fertigation The farmers of South Saurashtra Agro-Climatic zone growing Bt. cotton crop are recommended to apply 25 % of RDF (240 N:50 P2O5:150 K2O kg/ha) as basal doze and remaining NPK through drip fertigation in 12 equal splits after 30-45 days of sowing at 9 days interval using following drip irrigation system to get higher yield, net return, and water productivity as compared to conventional fertilizer applications adopted by farmers.

Identification of potential groundwater recharge zones in ozat river basin The scientific communities are informed that the planning for recharging of 610.18 MCM runoff (75% dependability) of Ozat basin may be done by recharging through 4520 check dams, 51113 farm ponds, 22599 open wells, 5650 tube wells in excellent and good groundwater recharge potential zones, while 10496Gabion/loose rock dams in moderate groundwater potential zones.
4.
Yield response of drip fertigation for wheat-green gram crop sequence The farmers of South Saurashtra Agro-Climatic zone growing wheat are recommended to apply 75 % of NPK of RDF (120 N:60 P2O5:60 K2O kg/ha) through drip fertigation only (with no basal doze) adopting the following drip system and irrigation schedules to wheat crop in 8 equal splits at 6 days interval after 12 days of sowing to get higher grain yield and net return.

It is also recommended to sow green gram crop in paired row (0.3 m x 0.375 m) after harvesting of wheat crop without any cultivation operation and to apply 75 % P of RDF (20 N:40 P2O5:00 K2O kg/ha) as basal doze and 75 % N of RDF through drip fertigation adopting the following drip system and irrigation schedules in 5 equal splits at 6 days interval after 12 days of sowing to get higher seed yield and net return.

5.
Development of semiautomatic channel for border irrigation Farmers are recommended to use metallic or PVC border irrigation channels developed by Junagadh Agricultural University instead of kachha channels to reduce seepage loss up to 87% compared to kachha channels. Adoption of border irrigation channels can increase the additional crop area by 200 sq. m per hectare. With a system lifespan of five years, the annual cost was found Rs. 1,029 and Rs. 440 per meter of channel length for metallic and PVC channels, respectively. With automation, the annual cost was Rs. 1,232 and Rs. 643 per meter of channel length for metallic and PVC channels, respectively.
