The Cork City flood of November 2009 : lessons for flood risk management and climate change adaptation at the urban scale

The Cork City flood of November 2009 : lessons for flood risk management and climate change adaptation at the urban scale
Adaptation ; Climatic change ; Cork ; Flood ; Flood control ; Hydraulic works ; Ireland ; Northern Ireland ; Risk management ; Urban area ; Vulnerability
Drawing on the example of Cork City and the November 2009 flood in particular, this paper evaluates contemporary policy and decision-making responses to flood hazards to determine whether they are sufficient to address current and future flood risks
and vulnerabilities. This framing of flood hazards is shaped by several influences including the historic evolution of flood policy and current institutional structures. The November 2009 flood highlights the limits of current policy and practice.

Flash flood ; Flood ; Hydrology ; Natural hazards ; Physical geography ; Risk management ; Slovenia
Structural measures play an important role in flood risk management. Their usage enables us to manage a certain part of flood risk. Their main purpose is to reduce flood hazard on flood-prone areas that have been inhabited or used for different
human activities. The paper presents some of most common structural measures which serve for flash flood protection, the basic principle of operating, its advantages and disadvantages, as well as their environmental impact. - (IKR)

Vertical mixing of gravel over a long flood series

Vertical mixing of gravel over a long flood series
British Columbia ; Canada ; Flood ; Grain size distribution ; Gravel ; Island ; Sediment load ; Sediment transport ; Stream ; Tracer ; Vancouver
This paper describes the characteristic depth of exchange achieved over a long flood series. Analysis is based on 11 recoveries of magnetically tagged gravels deployed in Carnation Creek, Canada, completed between 1990 and 2008. Both active
and passive grain exchanges throughout most of the bed produce the overall vertical distribution of marked grains. Gravel exchanges exhibit fairly consistent patterns once tracers are well mixed by large floods. Results highlight the role of flood sequence

Assessment of the geomorphic effects of large floods using streamgage data : the 1951 floods in eastern Kansas, USA

Assessment of the geomorphic effects of large floods using streamgage data : the 1951 floods in eastern Kansas, USA
Aerial photography ; Bank erosion ; Channel geometry ; Flood ; Floodplain ; Kansas ; LiDAR ; Measurement ; River bed ; Stream ; Stream flow ; United States of America
Data from 23 U.S. Geological Survey (USGS) streamgages were analyzed to assess the geomorphic effects (short-term change and subsequent recovery) of the record 1951 floods on streams in eastern Kansas. Flood-related, channel-bed elevation change
was indicated for 17 gage sites, with substantial deposition at 5 sites and substantial erosion at 2 sites. An assessment of post-flood bed elevation recovery was possible for several sites. It was demonstrated that an analysis of streamgage data
is a potentially useful technique for assessing the geomorphic effects of a large flood at a site, provided that the gage has a long period of record and is located on an alluvial channel.

The effect of river floods on the morphology of small river mouths in the southeastern Mediterranean

The effect of river floods on the morphology of small river mouths in the southeastern Mediterranean
Aerial photography ; Channel geometry ; Coastal environment ; East Mediterranean Sea ; Flood ; Fluvial dynamics ; Geographical information system ; Israel ; Mediterranean Sea ; River mouth ; Stream
This study examines the effect of floods on the dynamic morphology of 7 of these river mouths between 1918 and 2005. The methodology is based on GIS techniques and utilizes over 300 aerial photographs from which detailed geomorphologic mapping
of river mouths and nearby geomorphologic elements was performed. River discharge records were incorporated into a database, permitting analysis of the effect of floods on the morphology of the river mouths. Based on their adjacent topography, 2 types
of mouths were recognized, each responding differently to river floods. In funnel topography mouths, flood morphology almost always displayed straight channels. In barrier-deflected mouths the response to floods is more complex.

This article presents a procedure, by which to identify small drainage basins vulnerable to the propagation of abrupt flood waves, and hence to flash flooding, in response to short-duration episodes of very intensive rainfall. Long known
for such local flooding events, basins in the Carpathian were described by reference to a large number of physiographic characteristics of importance to the generation of abrupt flood-wave phenomena. Features found to be associated with an enhanced probability
of such flash flooding (thanks to faster transformation of precipitation into outflow) included: basin area, slope and changes in elevation along the valley, but also land-use structure, physical properties of the soil and the configuration and density
of the river network. The results of multidimensional analysis provided for the identification of types of basin vulnerable to the flood-wave formation in question. – (BJ)

Interdecadal variation of east Asian summer monsoon and drought/flood distribution over eastern China in the last 159 years

Interdecadal variation of east Asian summer monsoon and drought/flood distribution over eastern China in the last 159 years
Based on the drought/flood grades of 90 meterological stations over eastern China and summer average sea-level pressure (SLP) during 1850–2008 and BPCCA statistical methods, the coupling relationship between the drought/flood grades and the East
Asian summer SLP is analyzed. The results show that there are 4 typical drought and flood spatial distribution patterns in eastern China, i.e. the distribution of drought/flood in southern China is contrary to the other regions. It is suggested
that there is a relationship between solar activity and the East Asian summer monsoon and the interdecadal variation of drought/flood distributions.

This paper deals with long-term above and below normal monsoon precipitation causing prolong meteorological droughts and floods in India. Five regions across India comprising variable climates were selected for the study. Apart from long-term trends
monsoon floods were found to have negative long-term trends everywhere except in the peninsular Indian region. The results overall suggest generic conclusions concerning the region-wide long-term trend of severity of monsoon droughts and floods in India
