Rainfall distribution is one of the parameters required for calculations of the design flood. The pattern of rainfall distribution is the mean of rainfall expressed in a graph that describe variation in depth of rainfall to time function. The pattern of rainfall distribution is obtained in two method, empirical method and averaging hourly rainfall data. The rainfall data used is obtained from TRMM (Tropical Rainfall Measuring Mission) JAXA (Japan Aerospace Exploration Agency) in eight years (2009-2016) for Kampar Regency. In this research, approach the pattern of rainfall distribution between the hourly rainfall average of TRMM with empirical methods to simplify the acquisition pattern of hourly rainfall distribution. The empirical method used is ABM (Alternating Block Method), Modified Mononobe, and Tadashi Tanimoto. The analysis results of hourly rainfall distribution pattern approach of JAXA TRMM with empirical method shows that rainfall duration 3 to 8 hours tends to approach ABM pattern. Analysis of rainfall distribution based on correllation shows that rainfall duration 3 (three) until 7 (seven) hours tends to approach ABM and rainfall duration 8 (eight) hour tend to approach ABM or Tadashi Tanimoto.
