“…The average NRMSE, MRE, and NSE were 19.0, 0.31, and −0.43%, respectively. This was close to the model performance as reported by Noory et al (). It could be concluded that the calibrated and validated distributed model has the potential to evaluate irrigation management and performance in the HID.…”

In the Hetao Irrigation District (HID), reduction of the diverted Yellow River water for agriculture makes partial replacement of fresh water for irrigation by shallow saline groundwater a possible way to alleviate the shortage of freshwater resources. In this study, a SWAP‐WOFOST agro‐hydrological model was calibrated and validated, and then applied in a distributed manner to estimate crop yield, water productivity (WP) of spring wheat, spring maize, and sunflower, and soil salinity with conjunctive use of saline and non‐saline irrigation water during 2000–2010, and a crop zoning was proposed based on simulated crop WP in the HID. Compared with non‐saline water irrigation, the annual average yield of spring wheat, spring maize, and sunflower was changed by −0.2, 5.3, and 8.2%, and the WP was changed by −5.5, 2.6, and 7.6%, respectively, with conjunctive use of saline and non‐saline irrigation water according to the proposed crop zoning. Soil salinity in the rooting zone did not increase with time. The salts remaining in the subsoil were very little, which did not obviously affect the groundwater salinity. Our results demonstrated that partial substitution of fresh water by shallow saline groundwater for irrigation is feasible in the HID. Copyright © 2017 John Wiley & Sons, Ltd.

“…Fernandez, Skaggs through the combination of drains convergence model and field drainage hydrology model DRAINMOD, proposed a lumped parameter watershed scale hydrological model, in which drains convergence model is by ignoring the inertia in the Saint-Venant equations after solving diffusion wave equation [34]. Noory applied SWAP model in distribution of form to the irrigation area of Iran and analyzed the influence of irrigation water management on water-and-salt balance in irrigation area to seek optimal irrigation water management model [35]. Chen proposed the concept of dispersed tank model, described rice fields, dry fields and ditches existing yield confluence characteristics at the same time in irrigation district, adopted weir trough hydraulic model to connect flow and simulated regional surface runoff [36].…”

Global climate changes and human activities have a profound impact on disaster environment and formation mechanism of waterlogging disaster, exacerbating the uncertainty of waterlogging disaster and highlighting complexity and difficulty coping with the water disasters of farmland. A large number of researches on risk assessment and prediction of flood disaster have been carried out at home and abroad, and this study concluded the research progress of this direction in recent years in terms of six aspects including the connotation of disaster risk, comprehensive assessment of flood risk based on index system, the numerical models of flood disaster risk assessment, the regularity analysis of different carriers, the influence of environment changes on flood disaster risk and uncertainty of flood disaster and finally analyzed problems in the research and the future directions of development.

“…For irrigated areas success and safeguarding, monitoring of watertable characteristics (level and water salinity) and soil salinity constitute a tool to predict and reduce salinization risks within irrigated soils. In this context, throughout last decades an evaluation of hydrosalin balance have been performed within several irrigated areas around the world in order to assess salt loads in irrigation return flows (Australia: [14]; India: [18]; Iran: [11]; México: [12]; Spain: [6]; Tunisia, Turkey: [4]; USA: [17]). Nevertheless, the majority of studies was performed considering short periods of time and did not allow identifying long-term impacts of agronomic changes and climatic variability on salt load trends.…”

. Modeling of hydrosaline balance using CIRFLE model indicates that drainage water volume showed a linear variation with irrigation water volume and rainfall amount variations with dominance of rainfall effects by comparison to irrigation water volume ones. In fact, for the same variation index (+20%) of irrigation water volume and rainfall amount it was found that drainage water volume has increased by 10% and 25% respectively. However, CIRFLE simulations have shown that drainage water salinity variation is inversely proportional to irrigation water volume and rainfall amount variations. Thus, any increase of irrigation water volume and rainfall amount causes a decrease of drainage water salinity and vice versa with dominance of rainfall amount effects. On the other hand, it is noted that drainage water salinity is linear with that of irrigation water salinity. Furthermore, simulations have shown that evacuated salts amounts by drainage is proportional to irrigation water salinity, irrigation water volume and rainfall amount variations. Thus, it was found that rainfall effects dominate those of irrigation water volume whose dominate the effects of irrigation water salinity. Therefore, for the same variation index (+20%), increases of evacuated salts amounts by drainage of 20%, 16% and 8% were recorded respectively with rainfall amount, irrigation water volume and irrigation water salinity increases.
