Water Resources Engineering

Water Resources Engineering for GATE Civil Engineering, one topic per lesson: the theory in plain words, the formulas, a solved example, and GATE-style questions (MCQ, MSQ and NAT) whose numerical answers are recomputed by a program when the site is built.

Start the first lesson

1Hydraulics

  1. Open Channel Flow and Specific EnergyUniform flow with Manning's and Chezy's equations, most economical channel sections, specific energy, critical depth, Froude number and gradually varied flow profiles.
  2. Hydraulic Jump and Flow MeasurementHydraulic jump in rectangular channels, sequent depths, energy loss, types of jump, and flow measurement with weirs, notches, venturi flumes and orifices.

2Hydrology

  1. Hydrology: Precipitation, Losses and RunoffHydrologic cycle, rain gauges and average rainfall (arithmetic, Thiessen, isohyetal), double mass curve, evaporation and infiltration, phi-index, rational method and hydrographs.
  2. Unit Hydrographs, Flood Routing and GroundwaterUnit hydrograph theory and S-curve, peak flow from unit hydrographs, reservoir and channel routing (Muskingum), aquifers, Dupuit's well equations, and yield of wells.

3Irrigation

  1. Irrigation EngineeringCrop water requirement, duty, delta and base period, consumptive use, irrigation efficiencies, soil moisture and frequency of irrigation, Lacey's and Kennedy's silt theories, and canal structures.
