The 1998 flood had smaller peak discharges than of the 1954 flood (largest flood in the 20 century) at most gauging stations in the middle and lower reaches, but resulted in higher peak stages. One of the reasons of this higher water stages is the decrease in the surface area and storage capacity of natural lakes due to the excess impoldering agricultural land and sedimentation. However, there ...

Annual flooding in low-gradient rivers is recognized as an important subsidy between the river and its broad adjoining floodplains. Unfortunately, relatively few lowgradient rivers are unregulated and retain their natural "flood pulse" behavior in most developed regions of the world. Furthermore, attempts to quantify flood inundation dynamics of any river floodplain are scarce. We used aerial p...

Breaching of coastal barriers is a three-dimensional process induced by complex interactions between hydrodynamics, sediment transport and soil avalanching processes. Although numerous coastal barriers are breached every year in many coastal countries, causing dramatic inundations of the nearshore areas, the understanding of the processes and interactions associated with both breaching and subs...

Flood damage can be minimised by ensuring optimum capacity to drainage structures. An underdesign of these structures increases flood damage cost whereas an overdesign incurs unnecessary expenses. The optimum design of water infrastructures depends largely on reliable estimation of design floods which is a flood discharge associated with a given annual exceedance probability. For design flood e...

one of the most important discharge control ways in hydraulic structures is side weir which is used in irrigation, water distribution, waste-water engineering, drainage, flood control and other water related projects.in order to increases cm value and control on water surface when there is restriction in the weir length(l), side weir with different geometry is used. in present research seventhl...

Effective flood assessment and management depend on accurate models of flood events, which in turn are strongly affected by the quality of digital elevation models (DEMs). In this study, HEC-RAS was used to route one specific water discharge through the main channel of the Eskilstuna River, Sweden. DEMs with various resolutions and accuracies were used to model the inundation. The results showe...

Existing methods of evaluating the hazard posed by moraine-dammed lakes are unsystematic, subjective, and depend on the expertise and biases of the geoscientist. In this paper, we provide a framework for making objective preliminary assessments of outburst flood hazard in southwestern British Columbia. Our procedure relies on remote sensing methods and requires only limited knowledge of glacial...

Received XXXX; accepted XXXX Abstract Series of observed flood intervals, defined as the time intervals between successive flood peaks over a threshold, were extracted directly from eleven approximately 100-year streamflow datasets from Queensland, Australia. A range of discharge thresholds were analysed that correspond to approximately 3.7 months to 6.3 year return periods. Flood interval hist...
