The document provides instructions for filling out a table to calculate runoff from rainfall using the Rational Hydrograph method. It begins with inspirational words and acknowledges those who helped with the research. It then lists input values like rainfall duration, catchment area, and rainfall height that should be entered into columns B(6) and B(7) of the provided table. Finally, it thanks the recipient's wife and daughters, as well as the Environment Agency and people of Samosir Regency for their support.
