Irrigation & Water Management

More crop per drop. Hydrology, open-channel flow in canals, pumps, crop water requirement and drip/sprinkler system design.

• Hydrology — Hydrology quantifies water in the environment. Learn the hydrologic cycle, rainfall (intensity–duration–frequency, return periods and risk), infiltration and runoff (rational method, SCS-CN), time of concentration, hydrographs and unit hydrographs, and flood design.
• Open Channel Flow — Open channels carry water with a free surface: rivers, canals, drains, culverts and sewers. Learn uniform flow (Manning), Froude number, specific energy and critical depth, hydraulic jumps, weirs and channel design.
• Pumps — Pumps add energy to liquids. Learn centrifugal vs positive-displacement pumps, head, flow and hydraulic power, pump and system curves, efficiency, affinity laws, NPSH and cavitation, and series/parallel operation.
• Irrigation Engineering & Crop Water Requirement — Supplying the right water at the right time. Learn reference evapotranspiration (FAO-56 Penman–Monteith), crop coefficients and crop ET, effective rainfall and net/gross irrigation requirement, irrigation efficiencies, surface irrigation (basin, border, furrow), sprinkler and drip system design (emitters, laterals, uniformity, hydraulics, pump sizing), fertigation, deficit irrigation and automation — with Python for ET₀, crop ET and a drip-system run time.
