To forecast the flows in a large drainage basin using the unit hydrograph method would be difficult because in a large basin geographic conditions may vary significantly from one part of the basin to another.
32.
In the world of academia and hydrology he is known for his numerous publications in the field with unit hydrograph theory developed by Dooge in 1959 and is generally regarded as a pioneer in the field.

"' RR module "': a rainfall runoff module, including the unit hydrograph method ( UHM ), a lumped conceptual continuous hydrological model and a monthly soil moisture accounting model.

35.
For example, a basin model can calculate the runoff hydrograph that might result from a 100-year storm, although the recurrence interval of a storm is rarely equal to that of the associated flood.
36.
For large basins, where unit hydrograph might not be useful and reliable, the magnitude and frequency method is used to calculate the probability of recurrence of large flows based on records of past years flows.
37.
The separation of baseflow from direct runoff in a hydrograph is often of interest to hydrologists, planners, and engineers, as it aids in determining the influence of different hydrologic processes on discharge from the subject catchment.
38.
Data in units of cumec are used along the y-axis or vertical axis of a flow hydrograph, which describes the time variation of discharge of a river ( the mean velocity multiplied by cross-sectional area ).
39.
This report describes methods for calculating the trapezoidal-distribution statistics and rank correlation coefficients for stochastic modeling of volume reduction, hydrograph extension, and water-quality treatment by structural stormwater BMPs and provides the calculated values for these variables.
40.
Building on the work of Horton, the unit hydrograph theory was developed by Dooge in 1959 . It required the presence of the National Environmental Policy Act and kindred other national legislation to provide the impetus to integrate water chemistry to hydrology model protocols.
