Chapter-wise study notes for Irrigation Engineering covering the complete ESE, GATE, and SSC JE syllabus.
Ready to practice? Launch the mock test below.
Irrigation Engineering carries 3–6% weightage in GATE Civil and 8–12 questions in ESE Prelims Paper II. Canal design, cross-drainage works, and diversion headworks are the most frequently asked topics across GATE, ESE, and SSC JE.
Irrigation Engineering mock tests will cover the complete ESE, GATE, and SSC JE syllabus on water resources utilisation, canal design, hydraulic structures, and drainage engineering.
Irrigation Engineering for GATE Civil and ESE covers: necessity and types of irrigation, duty and delta, canal design (Kennedy's and Lacey's theories, most economical section), distribution systems, hydraulic structures (weirs, barrages, sluices), dams (gravity dams — elementary profile, Bligh's and Lane's seepage theories, uplift pressure), waterlogging causes and remedies, drainage systems, water logging and salinity control, lift and canal irrigation, and command area development.
Irrigation Engineering (part of Water Resources Engineering) carries approximately 4–8% weightage in GATE Civil Engineering, typically 4–8 marks out of 100. Canal design using Lacey's theory, weir design, and duty-delta relationships are the most commonly tested topics.
In ESE Prelims Paper II (Civil Engineering), Irrigation Engineering typically accounts for 10–15 questions. ESE tests canal design (Kennedy's and Lacey's theories), hydraulic structures (weirs, barrages, head regulators), dam design, and waterlogging and drainage in greater depth than GATE.
