Modelo de escoamento superficial em bacia experimental da Reserva Florestal Adolpho Ducke

In this study, experimentation and hydrologic modeling of rainfall events transformed into runoff in natural forest systems, are investigated, including the following treatments: construction of an iterative optimization computational algorithm to identify the average unity hydrograph (rain-discharge transfer function) of the watershed, and to compute the effective rainfalls adequate to each discharge-rainfall event; applying the methodology to the Igarape Bolivia watershed, which is located inside the Adolpho Ducke Forest Reserve; analysis and interpretation of the established algorithm, focusing on its convergence and on the significance of the results of this optimization process; and comparison with other studies in small watersheds of Central Amazonia. Rainfall and runoff measurements were made from July 2004 to September 2006, including the preparation phase of the level-discharge curve of the Igarape Bolivia and the making of a large and diversified set of rainfall and runoff events.
