Hillslope Hydrograph Analysis Using Synthetic and Natural Oxygen-18 Signatures

Popis výsledku v původním jazyce

Shallow subsurface runoff is one of the most important mechanisms determining hydrological responses of headwater catchments to rainstorms. In this study, a simplified approach combining one-dimensional dual-continuum vertical flow in a variably saturated soil profile and one-dimensional saturated flow along the soil-bedrock interface was used to study rainfall-runoff events at an experimental hillslope. A dual set of Richards' equations was used to predict vertical flow of water in the soil matrix andpreferential pathways. Subsurface flow along the soil-bedrock interface was described by diffusion wave equation. The observed subsurface runoff and its oxygen-18 composition were compared with the model predictions. Contributions of pre-event and eventwater to hillslope runoff during major rainfall-runoff episodes were evaluated by means of numerical experiments involving synthetic oxygen-18 rainfall signatures. Although preferential flow played an important role in the hillslope runof
