Rainfall depth-duration-frequency (DDF) curves describe rainfall depth as a function of duration for given return periods and are important for the design of hydraulic structures. This paper focusses on the effects of dependence between the maximum rainfalls for different durations on the estimation of DDF curves and the modelling of Cited by: In this case, you can specify the number of times that data was collected per year by using the 'frequency' parameter in the ts() function. For monthly time series data, you set frequency=12, while for quarterly time series data, you set frequency=4. In computing records of lake or reservoir contents, it is necessary to have available from surveys, curves, or tables defining the relation of stage and content. The application of stage to the stage-content curves or tables gives the contents from which daily, monthly, or . Created Date: 5/6/ PM.

But for ordinary frequency distributions, a decision must be made about the number of bins. The only general rule is that the ideal number of bins has something to do with the size of the data set.

If the frequency distribution tabulates the frequency of a huge number of values, it makes sense to use a small bin width and so create lots of bins. P A METHOD FOR COMPUTING THE MONTHLY PALMER DROUGHT INDEX ON A WEEKLY BASIS: COMPARING DATA ESTIMATION TECHNIQUES Richard R.
