Title: Analysis of storm hydrograph and flow pathways using a three-component hydrograph separation model
Abstract: A three-component hydrograph separation model involving full chemical-isotopic mass balance equations is presented and tested using storm runoff and catchment hydrological and hydrochemical data from Allt a Mharcaidh catchment in Scotland. A key issue in the use of the model is the rational and objective selection of representative end-members given spatio-temporal variation in catchment hydrochemistry. In addition, a highly involved catchment sampling strategy should be adopted so that no key runoff source is omitted. End-member mixing analysis was used in determining the set of storm runoff end-members used in the model. Results show that incident precipitation, soil water and ground water contributed 15%, 19%, and 66%, respectively, of the June 1989 storm runoff. Maximum instantaneous contributions were 26%, 40%, and 78%, respectively.
