  • Potential analysis for synergetic flood retention measures in the Wandse River catchment

    The Wandse has a total length of 21,5 km with a catchment area of 88 km2. The source is located in Schleswig-Holstein where the upper part of river and catchment (aprox. 4,2 km and 20 km2) are of predominantly rural character. The lower part on Hamburg territory (approx. 17,3 km and 68 km2) is of urban character with a high percentage of sealed surfaces that drain to the Wandse or their ...

  • Flood modeling and mitigation measures in an Urban Environment –Victoria, Australia - Case Study

    Abstract Accurate prediction of flood extents in urban catchments is extremely difficult without having a 1d/2d integrated modeling approach. The integrated flood modeling is becoming popular and a new benchmark for urban flood risk management studies. City of Glen Eira in Victoria, Australia is a developed metropolitan municipality. The council is responsible for the management ...

  • Living with the floods, not against them

    “Yes, we are illiterate sir, but we are engineers as far as our experience with water and rivers is concerned”, says Phushi Mahato, a villager in the Gosi Kandak floodplains in North-Bihar in India. As an outcome of water resource management that failed to understand the role of fluvial regimes in delta, Phushi and his fellow village members have now become vulnerable to floods ...

  • Developing optimum solutions to flooding

    Developing optimum solutions to flooding With a very long period of wet weather in the summer overlaid by intense rainfall, 2007 was the wettest summer in the UK on record. This unusual weather pattern resulted in very high localised runoff, with three events in England exceeding the 1 in 100 year return period over that time – some of the worst flooding that has ever occurred in ...

  • Impact of floods, hurricanes and storms

    What happens to the water network in the wake of hurricanes and floods? Just days after Hurricane Harvey dumped over 50 inches of rain on the American state of Texas causing the deaths of 60 people and delivering billions of dollars worth of damage to homes and property, Hurricane Irma has wreaked havoc in the Caribbean with the most powerful Atlantic storm in recorded history. ...

  • Flood modeling and mitigation measures in an urban environment – a Case Study, Victoria, Australia - Case Study

    Introduction: Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of rivers during severe rainfall events. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural ...

  • Living with floods in the Mahanadi Delta, India

    In October 2013, one of the fiercest cyclones to hit the Bay of Bengal for many years made landfall on the low-lying delta coast of the Indian state of Odisha. With winds battering the coastline at more than 200 kilometres per hour, the structural damage from cyclone Phailin was intense. Thousands of straw, timber and bamboo homes were destroyed across the delta of the River Mahanadi, one of ...

  • Are preventive and coping measures enough to avoid loss and damage from flooding in Udayapur district, Nepal?

    This case study examines household vulnerability and responses in relation to flooding in Udayapur district, Nepal. It describes how communities in this region deal with flooding and asks to what extent their preventive, coping, and adaptation measures have been successful in avoiding loss and damage. A 300-household survey, along with open interviews and focus group discussions, revealed a wide ...

  • Modelling the Thatcham Flood - Case Study

    Overview On 20th July 2007, an unusual storm swept west across England along the approximate line of the M4 motorway. Thatcham, a town in Berkshire, was one of the worst affected. Many towns in England flooded that month from the Humber to Tewksbury. In fact there were 200 major floods worldwide in 2007 affecting 180 million people. Some of these floods were caused by rainfalls much more ...

  • Loss and damage from flooding in the Gambela region, Ethiopia

    In this article, we explore the ways in which people in the Ethiopian Gambela region dealt with the extreme flood that occurred in 2007, with specific attention to the associated loss and damage, i.e., the impacts that people were not able to avoid through preventive and coping measures. We found that all of the 431 surveyed households took preventive measures such as the construction of ...

  • Conversion to Extensive Grass Land for Flood Risk Management

    The Mitigation Strategy of the measure Conversion to Extensive Grassland refers to flood prevention and environmental protection also. Flood protection can be achieved by: Increase the infiltration of rainwater by high roughness and preventing soil silting, Reducing the flow velocity of surface run off, The hydrologic-hydraulic effect varies depending on the ...

  • ‘Smart’ flood alleviation system protects Portsmouth

    In late 2014, Southern Water completed a major project to reduce the risk of sewer flooding in parts of Portsmouth and Southsea. Substantial works were undertaken to divert runoff and tidal ingress, and a ‘smart’ hydrometeorological monitoring system was installed to enable prompt diversion of excess water during periods of high rainfall. Sewer level monitoring is undertaken in ...

  • Adaptation of sewer networks using integrated rehabilitation management

    The urban water structure is aging and in need of rehabilitation. Further, the need to address future challenges (climate change, urban development) also arise lines. This study investigates if it is possible to combine rehabilitation and adaptation measures. To do so, we combined an urban development model, an urban drainage model and a rehabilitation model. A case study of a medium-sized ...

  • An influence diagram for urban flood risk assessment through pluvial flood hazards under non-stationary conditions

    Urban flooding introduces significant risk to society. Non-stationarity leads to increased uncertainty and this is challenging to include in actual decision-making. The primary objective of this study was to develop a risk assessment and decision support framework for pluvial urban flood risk under non-stationary conditions using an influence diagram (ID) which is a Bayesian network (BN) ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • Contribution to a flood situation management: a supervisory control scheme to reduce disaster impact

    Inundations due to river overflows are becoming more frequent; management of flood is thus an important task belonging to the set of preventive measures allowing the protection of people and goods downstream. The flood situation management method proposed in this paper was designed to reduce the flood impact at its early arising stage. The river is supposed to be equipped with reservoirs in ...
