Streamflow Simulation for the Yellow River Basin Using RIEMS and LRM

The streamflow over the Yellow River basin is simulated by using the high-resolution RegionalIntegrated Environmental Model System (RIEMS), and an off-line Large-scale Routing Model (LRM).The RIEMS was designed and has been developed by the Global Change System for Analysis, Researchand Training Regional Center for Temperate East Asia (START/TEA) since 1991 and has a good capabilityto simulate the regional climate of East Asia. The LRM is based on the assumption of linearity and timeinvariance and can calculate the horizontal travel of water. The RIEMS-LRM allows the direct comparisonof predicted and observed streamflow data for large-scale rivers. The application of the RIEMS-LRM tothe upper reaches of the Yellow River verifies that the coupled model system has the capability to simulatethe streamflow over a large-scale river. Furthermore, the paper discusses the reasons leading to simulation errors.
