This unit enables learners to develop an understanding of the hydrological cycle and the importance of hydrological influences for civil engineering projects. Learners will also cover water supply, water treatment, and wastewater and apply hydrological design to civil engineering projects.

Outline Syllabus:Hydrological influences: hydrological cycle, surface water, groundwater, human influences, hydrological budget at the catchment scale, water balance calculations, reservoir storage requirements. Precipitation calculations: different methods of precipitation measurements, rain gauges, rain gauge network design criteria, recording of rain-fall data, missing value estimation. Quality control methods: infiltration, Horton's equation, phi index, SCS method, factors affecting infiltration and theories of evaporation (evapotranspiration and estimation). pan- evaporation, Penman's equation. Hydrological design: catchment characteristics (area, length, slope, runoff coefficients, land use and cover, streamflow). Principles of hydrological design: surface runoff, measurement of runoff, catchment characteristics (area, length, slope, runoff coefficients). Water collection and distribution: surface water collection, groundwater collection, water transmission systems, water distribution systems. pipeline and valves, hydraulics of pipelines, network of pipelines, valves, pumps and pumping installations. Wastewater collection systems: collection of sewage and stormwater, sewer materials, flow measurements in sewers, sewer installations and testing, hydraulics of sewer systems, quantities of wastewater flows, design of sewers, maintenance of pipes and equipment, urban runoff and combined sewer overflow management. Pollution: surface and groundwater pollution control, types and sources of pollution, effects of water pollution and control measures, solid and hazardous waste management, air pollution, noise control. Water treatment and standards: water treatment processes, environmental quality. Water quality (concepts, need of water quality studies and standards, physical/chemical/biological characteristics of water, water related diseases). Water supply systems, assessment of water demand, sources of water.
