The selection of dam site is the key content in early stage hydropower station project. Based on hydrology, topographic and geological conditions, kinetic energy economic indexes, flood loss reservoir, project layout, electromechanical metal structure, construction conditions investment proposed site, this paper makes an in-depth analysis pre-feasibility Shitouzhai Hydropower Station, order to ...

The safety of dikes in the Netherlands, located in the delta of the rivers Rhine, Meuse and Scheldt, has been the subject of debate for more than ten years. The safety (or flood risk) of a particular area may depend on the safety of other areas. This is referred to as effects of river system behaviour on flood risk (quantified as the estimated number of casualties and economic damage). In the N...

A comprehensive overview of methods to quantify and limit risks arising from different sources is still missing in literature. Therefore, a study of risk literature was carried out by the authors. This article summarises about 25 quantitative risk measures. A risk measure is defined as a mathematical function of the probability of an event and the consequences of that event. The article focuses...

We examine how historic flooding in 2011 affected the geomorphic adjustments created by dam regulation along the approximately 120 km free flowing reach of the Upper Missouri River bounded upstream by the Garrison Dam (1953) and downstream by Lake Oahe Reservoir (1959) near the City of Bismarck, ND, USA. The largest flood since dam regulation occurred in 2011. Flood releases from the Garrison D...

Peak and volume of river flows are functions of the catchment surface characteristics. This means that any impacts to the run-off regime (for example surface sealing and river training) could affect people and land users in the lower system. The costs of flood defence or compensation of damages are usually not included in the economic calculation of the upstream land owner or land user. In econ...

Natural disasters with minimal human mortality rarely capture headlines but occur frequently and result in significant morbidity and economic loss. We compared the epidemic activity observed after a flood, an earthquake, and volcanic activity in Peru. Following post-disaster guidelines, healthcare facilities and evacuation centers surveyed 10-12 significant health conditions for ~45 days and co...

Due to climate change, the frequency and intensity of Hydro-Meteorological disasters, such as floods, are increasing. Therefore, the main purpose of this work is to assess tangible future flood damage in the urban watershed of the To Lich River in Hanoi, Vietnam. An approach based on spatial analysis, which requires the integration of several types of data related to flood characteristics that ...

S ix years after the catastrophic failure of levees and other flood control structures during Hurricane Katrina, New Orleans continues to face the challenge of how to make the city more resilient and less vulnerable to future flood damage from the surge of water that can inundate cities and towns hit by major hurricanes. Past experience in New Orleans and other places has clearly shown that “st...
