## Partial Duration Series Solution

STEP 0: Pre-Calculation Summary
Formula Used
partial_duration_series = 1/ln(Annual Series)-ln(Annual Series-1)
TP = 1/ln(TA)-ln(TA-1)
This formula uses 1 Functions, 1 Variables
Functions Used
ln - Natural logarithm function (base e), ln(Number)
Variables Used
Annual Series- Annual Series are series composed of all and only the high flow events which exceed a pre-determined threshold value.
STEP 1: Convert Input(s) to Base Unit
Annual Series: 10 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
TP = 1/ln(TA)-ln(TA-1) --> 1/ln(10)-ln(10-1)
Evaluating ... ...
TP = -1.76293009543297
STEP 3: Convert Result to Output's Unit
-1.76293009543297 --> No Conversion Required
-1.76293009543297 <-- Partial Duration Series
(Calculation completed in 00.000 seconds)

### Partial Duration Series Formula

partial_duration_series = 1/ln(Annual Series)-ln(Annual Series-1)
TP = 1/ln(TA)-ln(TA-1)

## What is Log-Pearson Type III distribution?

The Log-Pearson Type III distribution is a statistical technique for fitting frequency distribution data to predict the design flood for a river at some site. Once the statistical information is calculated for the river site, a frequency distribution can be constructed.
