Flood Simulation based on ArcGIS in the Ungauged Area from Fugu to Wubao of the middle Yellow River

Abstract

Abstract:The Qingliangsigou and Jialuhe in the middle Yellow River are selected as the typical tributaries, history flood data in 1980-2013 and Horton infiltration capacity curve are used to calculate the stable infiltration rate and establish the model of runoff yield and concentration, the parameters are calibrated and applied in the ungauged area from Fugu to Wubao. The study area is divided into 20 units based on ArcGIS, Muskingum method parameters in each unit are calibrated, and typical floods of ungauged area from Fugu to Wubao are simulated. The results show that the simulation effects are good: the average error of peak time is about -0.4h, the error of peak discharge is in the forecasting allowable range, and the deterministic coefficient is 0.66.

“…They typically rely on ad hoc models that are tightly coupled to the simulation software, making it difficult to share, reuse, validate or combine with other models [7]. They are generally siloed within highly specialized subfields (as discussed above, or others, such as flood management [8]- [10], forest fire response [11]- [13], land use [14]- [16], or transportation [17], [18]). A formal and generic approach such as the discrete event system specification formalism (DEVS) can support multi-disciplinary simulation projects [19].…”
