In the intensity-duration analysis by Sherman, the intensity of rainfall i is represented as

• A. \(\frac{{{b^n}}}{{\left( {t + a} \right)}}\)
• B. \(\frac{{{a^n}}}{{{{\left( {t + b} \right)}^n}}}\)
• C. \(\frac{{{{\left( {a + t} \right)}^n}}}{b}\)
• D. \(\frac{a}{{{{\left( {t + b} \right)}^n}}}\)
