Planning of guide lines of river regulation is an important evidence for river conservation and regulation as well as water front function maintenance and management. Studying the flood control guide lines of river regulation is of great significance to protect river ecosystem and settle water rights scientifically and rationally. In this paper, thelayout principles of guide lines of river regulation in Qingzhang River were examined and proved. Several guide lines of river regulation width control parameters such as flow per unit width, flow velocity and water level rising value were proposed. Taking the Qingzhang River as an example for further research, the layout principle of the flood control guide lines of river regulation was refined, and the specific control parameters of the flood control guide lines of river regulation were put forward based on the analysis and calculation of the hydrological data of the Qingzhang River, and the application analysis of the results was carried out. The results show that the proposed layout principles and control parameters of flood control guide lines of river regulation are suitable for Qingzhang River, and the flood control guide lines laid out of river regulation in this way are reasonable.

This paper analyzed the water and sediment characteristics and eroding effect on river of flood in 2018. The result shows that this flood has the characteristics including large volume of water, long duration and high flood peak, the dis-charge of the flood peak coming into and routing through the Ningxia and Inner Mongolia reach of the Upper Yellow River varies from 2 880 m³/s to 3 600 m³/s, among which wick flood plains in the reach from Sanhuhekou to Toudaoguai arc overflowcxL The flood effects the Ningxia-Inner Mongolia reach evidently, it has an obvious effect of " depositing on floodplain and eroding channel" in Bayangaole to Sanhuhekou reach. The scour efficiency of overbank flood is higher than that of non-overbank floord. After the flood, the same discharge water level of Bayangaole and Simhuhekon stations in Inner Mongolia reach drops 0.71 m and 0.47 m respectively and the bankfull discharge increases 500 m³/s and 320 m³/s respectively.

Earth observation satellite remote sensing can provide reliable wide-ranging spatial information and is believed as one of the key technologies for flood risk identification and dynamic modelling. Aiming at illustrating how satellite remote sensing technology promotes flood studies,this paper reviewed the development and technical demands of flood risk identification and dynamic modelling research and analyzed the historical contribution and periodic utility of spatial remote sensing information in flood studies based on the 3-stage evolution trajectory of earth observation satellite remote sensing. Application progresses in 3 typical methods in flood studies,which are risk zoning,hydrological modelling and microwave remote sensing monitoring,respectively,have been discussed and summarized. Focuses of the future research on flood risk identification and dynamic modelling have also been pointed out,including the integration of remote sensing spatial information and model algorithms,the development and application of remote sensing algorithms and systems,the development and application of an integrated system for typical methods and the application of big data methodology and technology,in expectation of providing valuable references for improving the response capacity and risk management level of flood disasters.

This paper evaluated the risk of reservoirs collapse caused by nature-flood-based dam overtopping using a Bayesian network. Probabilities of single and cascade reservoirs collapse were calculated for reservoirs in Sichuan Province. The analysis demonstrates that Bayesian network is intuitive and user-friendly to investigate the risk of reservoirs collapse under multiple risk sources. A same conditional dam overtopping probability magnitude of 10-6 is derived, indicating a low risk of single reservoir dam overtopping. However, the conditional probability of dam overtopping is over 0. 8 when the water storage level is higher than normal, meaning there is a high probability of dam overtopping under this condition.

Combining flood hydrograph generalization and Support Vector machine for Regression ( SVR) , a new gradual and continuous channel flood forecasting technique was presented in this paper. A research about channel flood forecast was performed on the Wubu-Longmen reach of the middle Yellow River. Twenty eight flood events during the period between 1980 and 2000 were used to generate the flood hydrograph model and calibrate the SVR-GA models applied to forecast flood peak and duration. With the amplifier of forecasted flood peak and duration ,the flood hydrograph model was amplified to obtain the forecasted flood hydrographs. Five flood events during the period between 2001 and 2006 were forecasted to test forecast accuracy of the new technique. The results indicate that the forecast accuracy of the new technique increases continuously by using the updating relevant data. In addition, forecasted flood hydrograph performes well during the whole flood process. [ABSTRACT FROM AUTHOR]
