CE 2021 HYDROLOGY

OBJECTIVE
 At the end of the semester, the student shall be having a good understanding of all the
components of the hydrological cycle. The mechanics of rainfall, its spatial and temporal
measurement and their applications will be understood. Simple statistical analysis and
application of probability distribution of rainfall and run off shall also be understood.
Student will also learn simple methods of flood routing and ground water hydrology.

UNIT I PRECIPITATION

Hydrologic cycle – Types of precipitation – Forms of precipitation – Measurement of Rainfall –
Spatial measurement methods – Temporal measurement methods – Frequency analysis of
point rainfall – Intensity, duration, frequency relationship – Probable maximum precipitation.

UNIT II ABSTRACTION FROM PRECIPITATION

Losses from precipitation – Evaporation process – Reservoir evaporation – Infiltration process –
Infiltration capacity – Measurement of infiltration – Infiltration indices – Effective rainfall.

UNIT III HYDROGRAPHS

Factors affecting Hydrograph – Baseflow separation – Unit hydrograph – Derivation of unit
hydrograph – S curve hydrograph – Unit hydrograph of different deviations - Synthetic Unit
Hydrograph

UNIT IV FLOODS AND FLOOD ROUTING

Flood frequency studies – Recurrence interval – Gumbel’s method – Flood routing – Reservoir
flood routing – Muskingum’s Channel Routing – Flood control

UNIT V GROUND WATER HYDROLOGY

Types of aquifers – Darcy’s law – Dupuit’s assumptions – Confined Aquifer – Unconfined
Aquifer – Recuperation test – Transmissibility – Specific capacity – Pumping test – Steady flow
analysis only.
