The 2-D water flow mathematical model based on MIKE 21 software which reflects flood routing in the reach from Gaocun to Sunkou has been developed in this paper. Through the numerical simulation of the “96.8” typical flood, the simulating results in the condition of present topography are agreement with the measured ones. It shows that this model is basically reasonable in the selection aspects of river terrain, boundary treatment, roughness and water flow parameters, and the model has a reference value for simulating flood routing in the Lower Yellow River.

Boundary Treatment

The Lower Yellow River is apt to deposit and migrate. The reach from Huayuankou to Jiahetan is the typical wandering reach, which has broad and shallow body, intertwined tributary and numerous shoals. The mainstream always swings, and the riverbed deforms rapidly. There exist lots of residential places, irrigation canals, roads, productive dikes and other controlling works within the embankments, which greatly limits the scope of flooding. When the peak discharge is very large, the flood is prone to resulting in productive dikes bursting, which will greatly endanger the lives of residents in flood plains. The 2-D water flow mathematical model which reflects flood routing in the reach from Huayuankou to Jiahetan has been developed based on MIKE 21 software in this paper. Through the numerical simulation of the “96.8” typical flood, the simulating results in the condition of present topography are agreement with the measured ones. It shows that this model is basically reasonable in the selection aspects of river terrain, boundary treatment, roughness and water flow parameters, and the model has a reference value.

The 2-D water and sediment mathematical model which reflects silting in floodplain and scouting in main channel of over-bank flooding in the Lower Yellow River has been set up in this paper. Through carrying on 2-D water and sediment numerical simulation of the “96.8” typical flood, the author studied influence of over-bank flooding on flood travel and transverse exchange. The primary simulation results show that, adopting the over-bank flooding for silting in floodplain and scouting in main channel effectively guaranteed and expanded transverse exchange between floodplain and main channel and maintained the river channel vigor. This can relieve “secondary suspended river” states in the Low Yellow River to a certain extent; at the same time, the different magnitudes of over-bank floods have different effect of silting in floodplain and scouting in main channel.

Set Up

The 2-D water and sediment mathematical model which reflects flood retarding and sand silting of flood plain in the Lower Yellow River has been set up in this paper. Through carrying on 2-D water and sediment numerical simulation of the “96.8” typical flood, the authors studied influence of zoning flood retarding and sand silting on flood travel, flow structure of floodplain-channel and transver exchange of water and sediment. The simulating results in different conditions show that, adopting the zoning flood retarding and sand silting in the Lower Yellow River effectively worked on retarding flood and sharpening peaks in the flood retarding basin, guaranteed and expanded transver exchange of water and sediment in the floodplain and channel and maintained the river channel’s vigor. This can relieve “secondary suspended river” states in the Low Yellow River to a certain extent.

High Arsenic Groundwater

High–arsenic (As) groundwater poses a serious threat to human health. The upper and middle reaches of the Yellow River are well–known areas for the enrichment of high–arsenic groundwater. However, little is known about the distribution characteristics and formation mechanism of high-As groundwater in the lower reach of the Yellow River. There were 203 groundwater samples collected in different groundwater systems of the lower Yellow River for the exploration of its hydrogeochemical characteristics. Results showed that more than 20% of the samples have arsenic concentrations exceeding 10 μg/L. The high-As groundwater was mainly distributed in Late Pleistocene–Holocene aquifers, and the As concentrations in the paleochannels systems (C2 and C4) were significantly higher than that of the paleointerfluve system (C3) and modern Yellow River affected system (C5). The high-As groundwater is characterized by high Fe2+ and NH4+ and low Eh and NO3−, indicating that reductive dissolution of the As–bearing iron oxides is probably the main cause of As release. The arsenic concentrations strikingly showed an increasing tendency as the HCO3− proportion increases, suggesting that HCO3− competitive adsorption may facilitate As mobilization, too. In addition, a Gibbs diagram showed that the evaporation of groundwater could be another significant hydrogeochemical processes, except for the water–rock interaction in the study area. Different sources of aquifer medium and sedimentary structure may be the main reasons for the significant zonation of the As spatial distribution in the lower Yellow River.
