... As a temporary flood control equipment to deal with sudden storms and floods, it is widely used at the entrances and exits of important underground spaces in cities and towns. e first mobile flood wall in the world was installed in the urban area of Cologne, Germany in 1984, and then the same type of flood wall was put into use successively in places such as the Danube River in Austria, Baja, Hungary, and Brado in the Czech Republic [1][2][3]. At the beginning of the 21 st century, China begins to design and produce mobile flood control wall equipment. ...

The current natural environment is unpredictable with heavy rains and floods happening from time to time. In order to ensure the safety of underground workers, infrastructure, and rail transit, a mobile and expandable underground flood control wall was optimized and designed. The use of mortise-and-tenon structure splicing and modular extension design effectively increases the stability and useable area of the flood wall. The finite element analysis software was used to simulate and study the force of each component under combined loads, such as static water, dynamic water, and impact, to analyze the stability performance of the assembly such as anti-sliding, anti-tilting, and internal stress. The verification results show that when the designed and studied underground flood control wall equipment is fully deployed, the maximum stress is 220.762 MPa, and the maximum offset distance is 32.334 mm, which are all within the safe range. It provides innovative ideas for the optimization of the related flood control wall structure.
... Removable floodwall systems can be applied to individual buildings, smaller areas, or a large scale of the infrastructure such as dams, largesize port piers, railway tunnel portals, culvert openings of expressways, openings of civil air defense structures, and urban large-scale communities to prevent flood disasters (Chen et al., 2018). Compared with traditional flood protection methods, the removable floodwall takes advantage of the low labor intensity, high work efficiency, and small seepage (Kádár, 2015). Also, a removable floodwall gives protection in case of flooding and open access to the floodplain over the remaining time. ...

Integrating and storing digital data through Building Information Modeling (BIM) and 3D Laser Scanning is of most importance in terms of visualizing project information. In this respect, this study presents a systematic and practical approach for detecting the assembly quality of anchor plates for a removable floodwall through the integration of BIM and 3D laser scanning. The current methods for analyzing the assembly quality of anchor plates heavily rely on manual inspection and contact-type measurements, which are time-consuming and costly. Therefore, this paper examines a semi-automated method integrating the use of BIM and 3D laser scanning technology for rapid analysis of the assembly quality of anchor plates. In this context, the paper introduces the framework of an automatic dimensional and surface quality assessment method. The following sections describe the project flowchart, data collection, and quality inspection methodology. The study employs the data of a real project located in Heihe, China, to validate the level of technical feasibility and accuracy of the presented methods. The results indicated that the proposed integration of BIM and 3D laser scanning has the potential to produce a semiautomated and reliable method to control the assembly quality of anchor plates.
... With the severe situation of urban flood protection in China [14], mobile flood protection systems can satisfy the different quality of life and safety requirements for the urban residents. e mobile flood protection method has been successfully applied in many American and European countries [15]. For example, in 1984, Cologne City, first installed the mobile flood protection baffle to protect against river flood. ...
... Mobile floodwalls can be installed at river dams, largesize port piers, railway tunnel portals, culvert openings of expressways, openings of civil air defense structures, and urban large-scale communities to prevent flood disasters. Compared with the traditional flood protection method, mobile floodwalls have the advantages of low-labor intensity, high-work efficiency, and small seepage over traditional flood protection methods [15]. Mobile floodwalls improve the standard of urban flood protection and can effectively prevent flood disasters under the requirement of preserving the urban landscape [16]. ...

Mobile flood protection systems provide a standardized flood protection method with high reliability. A comprehensive test site for mobile flood wall was established with the support of real applications, which provided opportunities to perform various tests. The anchor plate installation, seepage characteristics, and stress behavior of mobile flood protection systems were investigated through a process test, a water impounding test, and a post loading/unloading test. Test results indicated that installing anchor plates either by direct fixing or by preopened slots and eyes satisfy the construction and normal work requirements. However, the former is preferable over the latter. The mobile flood protection wall leaks when filled with water, and the leakage changes exponentially with the level. The leakage accelerates when the water level exceeds 1.5 m, thus registering 300 L/h at the 1.7 m level. In the post loading test (0–100 kN), concrete plastic deformation was first observed. Then, residual displacement was developed in the posts. The stressing process indicated that the failure process in the post, anchor plate, and base concrete system propagates from the concrete on both sides of the anchor plates toward the water side.

Analysing seepage phenomenon occurred in: earth irrigation system, storages, ponds and other earth structure as dikes or earth dams is very important task to be carry out in order to avoid any threat that may come as result of any possible failure, [22]. Earliest, attention has been given generally on estimation of seepage loose regarding especially to channel system and storage dam, while nowadays is given attention both amount of water loose and impact on environmental degradation, [23]. ...

World experiences reveal that catastrophic floods are posing a serious threat that comes not only from them as extreme events but also as the result of adaptation measures uncertainty, (i.e. dikes). In particularly old dikes constructed earliest at the north part of Albania, during the last floods demonstrated the high uncertainty and weak spots. In this paper, the significance of the seepage investigation and stability analysis are discussed. As a case study, parts of new dikes constructed last years along the Buna River located in north part of Albania are investigated. Filling materials for these dikes are represented mostly from silt and clay. Finite element method is used to perform seepage analysis while general limit equilibrium method is used to perform slope stability analysis. Both, seepage and slope stability analyses are done for three different scenarios: steady state, rapid filling, and rapid drawdown. Finally, it is concluded that silt-clay material used in these dike structure is posing serious uncertainty during seepage phenomenon by threatening the stability of entire dike structure especially during the transient condition (rapid filling and drawdown).
Chapter
The chapter deals with the issues of water abundance and water scarcity. In general, too much water means the dangers of increased water runoff and discharge. In the first part, the different types of floods and inland excess water are summarised, along with their causes and the human and financial consequences of this natural hazard. It also deals with flash floods, a specific type of flood, which are becoming more frequent and destructive due to climate change. It details the drought due to water scarcity, which is the most serious natural hazard in many regions of the world. This hazard is regionally differed due to climate change, but its increasing size and intensity sometimes causes damage at least as severe as earthquakes. However, the spread of information about this hazard is slow by nature and therefore does not appear to be a serious problem. The risk of soil and wind erosion is also analysed in this chapter. This process is often not considered a natural hazard in the strict sense of the term, because it is generally not a natural hazard from a human point of view but can cause significant damage from an economic point of view. This chapter also looks at ways of reducing this effect.
