Analysis of Flood Storage Area Operations in Huai River Using 1D and 2D River Simulation Models Coupled with Global Optimization Algorithms

Abstract: This article addresses the issue of flood management using four flood storage areas in the middle section of Huai River in China which protect the important downstream city of Bengbu. The same areas are also used by the local population as residential and agricultural zones. An optimization problem is therefore posed, with two objectives of simultaneously minimizing the downstream flood risk in Bengbu city and the storage areas’ economic damages. The methodology involved development of river flood models using… Show more

“…The 2D hydraulic modeling requires an impressive and accurate volume of information regarding the spatial data (e.g., terrain model, bathymetric model, roughness coefficient) and hydrological data. According to these requirements, the HEC-RAS software [23][24][25] has the ability to simulate an inflow flood using three different methods: one-dimensional (1D) unsteady flow model [57], two-dimensional (2D) unsteady flow model [58], and level pool flow model [59]. Therefore, due to the high density of human settlements downstream of the R1 reservoir in conjunction with the availability of all necessary data (e.g., LiDAR-derived DTM, bathymetry data, hydrological data, and roughness information), we considered the 2D hydraulic modeling as the most appropriate method for testing the flood control capacity of Başeu multi-reservoir system.…”

“…As the key flood control project, the flood storage area is used to temporarily store some of the floodwaters to reduce the rising rate of the water stage in the channel. It is usually achieved with a flood sluice between the flood storage area and the river [7][8][9]. The flood-control-protected area, which contains riverside cities (or industrial and mining areas), is essential to protect high-density populations and GDP within the area [10].…”

“…Human activities are recognized as a major factor affecting river runoff [10]. This appears in deforestation, land use change, soil and water conservation practices, and exploitation of surface and groundwater reservoirs and water supply [11,12]. Human activities have many negative effects on the environment [13].…”
