Abstract

Introduction Protecting water resources is a priority issue in natural resourcs management and is essential to sustain both human and ecological communities. Both WATER QUALITY and quantity influences the growth and health of human populations as well as affects ecological health of watershed systems.Human activities has had profound effects on rivers and streams world-wide, with many freshwater systems being impacted by multiple physical (e.g. channel straightening), chemical (e.g. contamination by organic and inorganic pollutants) and biological (e.g. introduction of invasive species) stresses. The nature of anthropogenic disturbance varies within catchments affected by different land uses. For example, agricultural land use may be characterized by increased inputs of non-point source sediments and pollutants, combined with more erratic hydrology due to the increase in impervious surfaces, and restricted ecological interactions between waterways and their land margins caused by removal of riparian vegetation. Land uses change the natural functions of a watershed by impeding or altering water flow and impacting WATER QUALITY.
