“…Flood losses have become an increasingly frequent phenomena [1][2][3][4][5] and flood hazard depends on two factors. The first is the natural ability of the watershed to generate floods from precipitation deposited over the watershed area.…”

“…The first is the natural ability of the watershed to generate floods from precipitation deposited over the watershed area. The second is related to human activity related to the use of water and lands located along the rivers and streams [5][6][7][8][9]. It has been suggested that increasing industrialization reinforces climate change at the local and global scale.…”

Possibilities of Controlling the River Outlets by Weirs on the Example of Noteć Bystra River

et al. 2020

The possibility of effective control of selected dams in the Noteć Bystra river is analyzed. Such a control is expected to permit inundation of selected arable areas, e.g., peat grasslands, to avoid flooding of the city of Czarnków and the terrains located downstream. The chosen case study is the reach of the Noteć River between the dams Pianowka-Mikolajewo-Rosko. The analysis was made on the basis of simulations of the flow and regulation of dams in flood conditions. The flow peaks of hypothetical flood waves were designed according to the directions of the ISOK project (Informatyczny System Osłony Kraju przed nadzwyczajnymi zagrożeniami-IT System of the Country's Protection Against Extreme Hazards) as the maximum flows over 10-years (p = 10%), 100-years (p = 1%), and 500-years (p = 0.2%). The obtained results are presented as longitudinal profiles of the water surface, maps of inundated areas and maps of inundated soils. The main conclusion is that the robust control of dams reduces the peak of flow during flood wave propagation and forces inundation of the a priori selected areas. It helps to decrease the spatial range of the flood hazard and significantly reduces risk related to floods.Sustainability 2020, 12, 2369 2 of 20 reduce flood consequences [21,22]. Efficient decision support systems should permit analysis of weather forecasts as well as analysis of watershed outflow generation. Such a system should support determination of reservoir decision rules on the basis of all available information including reservoir capacity and current amount of water stored [23,24].The impacts of climate change on hydrological alteration such as floods and drought pose a significant threat to floodplain environments [25][26][27]. Integrated water resources management (IWRM) is a practical approach which promotes responsible development and management of water and land resources considering the main parts of sustainability, i.e., economy, equity, and environment [28,29]. Adaptation of existing water infrastructure to climate change is becoming an important strategy for water management in floodplain areas. Karpack et al. [30] have suggested that humans have impacted on floodplain functionality by changing the physical landscape of floodplains and by altering river flows. A generally accepted solution used for flood protection is construction of reservoirs [31,32]. This study shows that the water infrastructure (weirs and dams) located in rivers could also be effectively used for water management including flood protection as well as for regulation and control of seasonal inundation at floodplain areas. Similar results have been obtained by Contreras et al. [33], who have shown that river flood manipulations by weirs and sluice gates provide water for agricultural activity without costly infrastructural and technical investigations.Analysis of flood risk has become very important and is the basis for the EU Flood Directive that started to take effect from November 26th, 2007 [34]. The Directive obliges Poland as well as othe...

“…As new developments continue, roads and buildings built in flood prone areas are facing increasingly more water hazards, including floods and erosion. In addition, in recent years, urban flooding (which has been considered to occur only in a few major cities in history [9][10][11]) has become increasingly more serious and common in China.…”

With the rapid progress of urbanization, cities’ demands for traffic flood control are steadily on the increase, and people are gradually paying more attention to traffic safety and environmental issues. Considering the considerable convenience and service ability of liquid air and corresponding products, people have begun to switch to using liquid air as an emergency coolant. However, this air’s cryogenic operation and vigorous vaporization expansion restricts its widespread application. Our study explores innovative applications based on liquid air spray/evaporation icing and natural melting, which can be applied to urban flood protection. This study also includes a brief introduction to the nature of liquid air and road icing, a conceptual design based on liquid air flash evaporation (for urban flood protection), and the modeling and solving of natural road ice melting. This paper introduces many innovative key technologies, which include the rapid solidification of floods to form emergency ice dams or diversion channels and the application of liquid air spray to form icy roads for the temporary passage of small cars or pickup trucks. Additionally, the economic estimations are performed by using downtown traffic flood control in Wuhan as an example to showcase our innovative scheme for applying liquid air spray/vaporization for urban traffic flooding control, which is practical, pollution free, and cost effective. Our innovative scheme will be promising for flood control in modern cities.

“…Flood disaster causes the greatest losses among natural hazards and it has become more severe and most frequent in recent years due to climate change, urbanization, and water infrastructures. [1][2][3]. Economic losses from flood hazards have considerably increased over the recent decades [4].…”

“…In the current study, we take the Dongting Lake, which is located downstream of the TGD, as an example to investigate how a lake can achieve a more effective role in mitigating a flood disaster in the middle or low part of a large river. Generally, a large lake (i.e., the mean surface area is greater than 500 km 2 [8]) plays an important buffer role for temporal floodwater detention during flood seasons [9,10]. However, a flood disaster still occurs when the incoming excessive floodwater is higher than a lake's effective storage capacity, which usually becomes very small relative to its total storage, because safe floodwater occupies most of its total storage (small/medium scale flood) as the dead storage before the peak flood wave arrives [11].…”

Flood Mitigation Using an Innovative Flood Control Scheme in a Large Lake: Dongting Lake, China

et al. 2019

A large lake plays an important role in mitigating flood disasters in its nearby regions during the flooding period; however, the effect is limited, because most of its storage capacity becomes dead storage prior to the arrival of the flood wave. In the current study, an innovative flood control scheme (IFCS) is applied to Dongting Lake (the second largest freshwater lake in China) to alleviate flood disasters. MIKE 21 FM was used to examine its feasibility to mitigate flood disasters. One of the largest floods in the 20th century, the 1998-type flood, was modelled and the maximum water levels with/without IFCS were compared. The result shows that the effective flood control storage could be at least doubled when compared with the natural condition once IFCS was applied. The peak flood level in the Dongting Lake could be lowered by at least 0.32 m at the Chenglingji station in the same flood passage of Dongting Lake. The case study reveals that, after applying IFCS, the hydraulic gates play a very important role in floodwater regulation and further study should be conducted to find the optimized operation for each gate in the flood control scheme system.
