In most subtropical regions, population growth seals the lands and, as a consequence, increases peakflows. This work aims to study overland flow generation in paired subtropical basins (one urbanized, other forested), in the metropolitan region of Campinas. Both, Cachoeira stream basin (urbanized) and the Jardim creek basin (forested) are to be monitored with lysimeters, to assess overland flow, water retention and groundwater recharge, stage-meters, to catch peakflows, and weather stations, to follow atmospheric physical conditions. A standpipe lysimeter is also to be constructed in laboratory to reproduce the field lysimeter water fluxes, in terms of top excess water with a faced spillway at the of the soil column, water retention with tensiometers along the column height, and percolation water with gravels and a drainage collector. It is expected throughout this work to contribute to 1) application of soil sciences in hydrological analysis and 2) testing soil profiles in laboratory.
