An update on the use of the RORA program is provided to supplement information given in the initial description of the program in Ground Water in 1994. The method estimates ground water recharge on the basis of streamflow records. Important considerations in the use of the automated approach are described that should improve the reliability of recharge estimates and avoid misapplication of the technique. Topics include the recession index, errors caused by direct surface runoff, the time scale for reporting results, comparisons with results of manual calculations, and errors caused by gradual recharge and discharge. The use of ground water levels for independent assessment of results from RORA is also described. RORA results are compared and contrasted with results from other base flow separation techniques.
本文提供了RORA程序使用情况的更新内容，以补充1994年发表于《地下水》杂志的该程序初始描述中所给出的信息。该方法基于河流流量记录估算地下水补给量。文中描述了使用自动方法时的重要注意事项，这些注意事项应能提高补给量估算的可靠性，并避免该技术的误用。主题包括消退指数、地表径流直接造成的误差、结果报告的时间尺度、与手工计算结果的比较，以及渐变补给和排泄造成的误差。文中还介绍了如何利用地下水位对RORA结果进行独立评估。将RORA结果与其他基流分离技术的结果进行了比较和对比。
