Land-Use-Based Runoff Yield Method to Modify Hydrological Model for Flood Management: A Case in the Basin of Simple Underlying Surface

The study of runoff under the influence human activities is a research hot spot in field water science. Land-use change one main forms and it also major driver changes to process. As for relationship between land use process, yield theories pointed out that capacity spatially heterogeneous. present work hypothesizes distribution can be divided by use, which is, areas with same land-use type are similar yield, while different uses significantly different. To prove it, we proposed land-use-based framework calculations based on conceptual rainfall–runoff model, Xin’anjiang (XAJ) model. Based framework, modified (L-XAJ) model was constructed replacing yielding area (f/F) storage curve XAJ ratio types (L/F; L specific types, F whole basin area). L-XAJ then applied typical cultivated–urban binary land-use-type (Taipingchi basin) evaluate its performance. Results showed great success demonstrated represent corresponding enhanced physical meaning generation expected used sustainable development resources.
