Flooding from main rivers is caused by heavy rainfall upstream, and can also be caused by flood surges up rivers from the sea – caused by high tides, low pressure and strong winds. ...

River flood risk map prediction is a combination of hydrological modelling, hydraulic modelling, river flood visualisation and river flood risk mapping. Two hydraulic models were applied in this research regarding their capabilities in river flood risk studies. These are MIKE11 developed by Danish Hydraulic Institute (DHI) and HEC–RAS4.0 by US Army Corps of Engineers. These two hydraulic models ...

Whether embankments should be used to control floods is a question of great importance in the eastern Gangetic plain, where embankment breaches cause severe flood damage every year and huge damage due to major breaches every few years. Critics of the embankment policy have called for a strategy of living with floods by building dispersed infrastructure to cope with floods. However, no ...

A Greater London Assembly report in 2011 stated that there was a 'serious risk' of flooding if London faces severe rainfall. Regardless of the Thames Barrier – which is there to protect against flooding from the sea, the London Assembly’s Environment Committee claim that some streets could flood from rain within minutes. Rainfall equal to what other parts of the country experienced in ...

Introduction The Missouri River stretches from western Montana to St. Louis, Missouri. The Corps manages six dams and reservoirs on the river to provide flood control and for other purposes, such as recreation and navigation. The Corps bases reservoir release decisions on the guidance in the Master Manual. In the 2011 flood, the Corps managed the highest runoff volume since 1898, ...

Urbanization and climate change trends put strong pressures on urban water systems. Temporal variations in rainfall, runoff and water availability increase, and need to be compensated for by innovative adaptation strategies. One of these is stormwater retention and infiltration in open and/or green spaces in the city (blue–green water integration). This study evaluated the efficiency of ...

First, a novel nonlinear Muskingum flood routing model with a variable exponent parameter and simultaneously considering the lateral flow along the river reach (named VEP-NLMM-L) was developed in this research. Then, an improved real-coded adaptive genetic algorithm (RAGA) with elite strategy was applied for precise parameter estimation of the proposed model. The problem was formulated as a ...

The aims of this paper are to present knowledge about the threat of flooding in the upper basins of the Myjava River, obtained using a questionnaire, and to identify the potential lessons for flood risk management. The questionnaire was designed to obtain information about households' experience with flooding, including the type of floods experienced, the locations of flooding, the ...

Periodic river floods have devastating social and economic impacts on poor households in the low-lying coastal and western regions of Kenya. This paper focuses on how households in Bunyala District coped with the impacts of flooding, and particularly the December 2011 River Nzoia flood. The data for the study was collected through a survey of 400 households, three focus group discussions, four ...

This study looks at the possibility of developing a cellular automata model incorporating tax and geographic conditions for simulating urban growth process with a view of using it in the future as a tool for directing growth in the city of Makassar, Indonesia. The developed model uses land tax values in addition to geographic condition constraints such as rivers, flood prone and nature ...

The paper presents the flood characterisation of the Haor region in the north-east of Bangladesh. The region consists of a system of Haors, each of which is a saucer-shaped depression and interconnected by a river system. A portion of the Haor area, known as the deeply flooded area, consisting of about 15 Haors, was chosen as the study area. A 1D2D model, with one-dimensional model for the ...

Various disasters in recent decades have confirmed that the risk from water-related events has been increasing significantly worldwide. Among those events are tsunamis, storm surges, river floods, flash floods, mass movements and droughts. The driving factors of this risk are the unabated increase in global population, the concentration of people in high-risk areas such as coasts, flood plains ...

In this paper, the problem of automatic control of pollutant on a shallow river using surface water systems is addressed using a benchmark test case based in the Ebro River. The Ebro River presents flooding episodes in the city of Zaragoza in Spring when snow melts in the Pyrenees. To avoid flooding and high pollutant levels in living areas, some lands outside the city are prepared to be ...

The report presents past and projected climate change and impacts in Europe by means of about 40 indicators and identifies sectors and regions most vulnerable with a high need for adaptation. The report covers the following indicator categories: atmosphere and climate, cryosphere, marine biodiversity and ecosystems, water quantity (including river floods and droughts), freshwater quality and ...

The problem of optimal operation of river–reservoir systems under flooding conditions is formulated in this study as a combination of particle swarm optimization (PSO) algorithm and a simulation model of river flood routing. Both hydrologic (Muskingum and Muskingum-Cunge) and hydraulic (solving Saint-Venant equations) flow routing methods are linked to the PSO algorithm with the objective ...

Dikes were the core of Dutch river flood protection. Near-floods in 1993 and 1995 and debates about climate change, however, led to a rethinking of existing approaches. In the policy directive 'Room for the River' the focus has shifted from infrastructure (dikes) to spatial measures (bypasses, dike relocations, 'green' rivers). While people and land used to be separated from water by dikes, this ...

By Isaiah Helm, SRS Crisafulli Applications Engineer The 2011 battle against the flooding Missouri, Mississippi, and Souris Rivers has been in the news.  The Souris River winds its way down from Canada into the Minot, North Dakota area and then back to Canada. Spring and Summer of 2011 saw real flooding ...

In order to alleviate the water supply–demand problem, a flood resource utilization strategy is proposed, called ‘Flood Utilization’. The strategy focuses on building large-scale water conservancy facilities and improving management measures. This paper presents the probability analysis of floodwater utilization in a confluence area, where a tributary joins a main river. Baicheng is used as ...

If the current wet climate state of the Souris River Basin continues during the next 10 years, there is a 2 percent chance another extreme flood, similar to that of 2011, will occur, according to a recent report by the U.S. Geological Survey and North Dakota State Water Commission. These and other findings about past and future flooding of the ...
