Résumé
The Coastal Bend of South Texas spans between Victoria and Corpus Christi. This study region is a semiarid water deficit area, which is undergoing anthropogenic impacts and climatic change. The main goal of the study was to assess the impacts of anthropogenic activities and climatic changes on streamflow in the study region. Historical data of streamflow, temperature, precipitation and peakflow for 28 years (1973-2000) was analyzed to study the trends in the data using different statistical methods. The results demonstrated an increasing trend in temperature in the study area, while no trend was obtained for precipitation. Areas with less anthropogenic activities like Perdido Creek and Aransas River watersheds did not show any trends in baseflow and runoff. However trends in baseflow and runoff components of overland flow were noted in watersheds where anthropogenic activity was significant.
