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.
