Study on Baseflow Separation of
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 9
Abstract
Objective: Currently, the evaluation of baseflow components have been of a worldwide concern due to the influential role of streamflow (base flow and direct flow)in agriculture, water sources management as well as supplying the potable water. Direct and field measurement of baseflow is not practicable especially in large areas with statistics deficiencies. Also, this would not be economically effective. So, there is a diversity of methods to estimate the baseflow. This study was conducted on "Abolabas" basin, a semi-arid region in the western-south of Iran. Methods: To estimate the baseflow, we employed the recorded data on daily streamflow within a lengthy period. We applied the smoothed minima baseflow separation of United Kingdom's Institute of Hydrology to assess the baseflow. For intermittent streams we used the developed model of this system (ADUKIH). ADUKIH is an efficient tool for separating baseflow from daily streamflow. Results: We compared ADUKIH to RDF and analyzed the outcomes. The results reflect that RDF is the most qualified (α=0.925). A striking similarity between two methods was observed ( R2=0.95).
