This document contains instructions for inputting data into a table to calculate potential maximum water retention time and measured runoff depth for each rainfall event based on rainfall depth. It thanks the document recipient's wife and daughters, as well as the Environment, Research and Development Agency of Samosir Regency Government of North Sumatera Province and the people of Samosir Regency. It also thanks alumni of PSMIL at Universitas Padjadjaran in Bandung.
