Synthetic Unit Hydrograph
Developing unit hydrographs often requires extensive data, making it feasible only for select locations. For data-scarce areas, synthetic unit hydrog…

Deriving Unit Hydrograph
Unit hydrograph is an effective hydrograph that tells us how a catchment would respond to a unit rainfall excess under a storm with duration of d -ho…
Direct Runoff Hydrograph
Base flow separation allows us to know which part of the hydrograph is contributed by quick-response flow i.e. direct runoff. To do so, we may use th…
Hydrograph
For hydrograph studies, we usually prefer a single peaked skew distribution of discharge over time, resulted from an isolated storm. A simple hydrogr…
Introduction to Runoff
Runoff is an output from a catchment. After fulfilling the requirements for others hydrological process such as infiltration and evapotranspiration, …
Indirect Streamflow Measurement
Streamflow may be measured indirectly using hydraulic structures. Such hydraulic structures can be categorized into two main groups, namely weirs and…
Stage-Discharge Relationship
Using the data of stage and discharge collected for a stream, we can develop its stage-discharge relationship and describe it using a rating equation…
Streamflow Measurement
Runoff is seen as an output from a catchment. Unlike other hydrological processes, we can measure the runoff reliably by determining the streamflow. …
