Abstract

Part of vulnerability to environmental hazards in urban areas is caused by storm water overloads. 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, Pinheirinhos stream basin (urbanized) and the Bom Jardim creek basin (forested) are to be monitored with lysimeters, to assess overland flow, water retention and groundwater recharge. Weather stations will monitore 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 spillway at the top 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. (AU)
