A number of hedonic property pricing studies of flood risk indicate that properties within a designated higher flood risk zone sell for a lower price than an equivalent property outside of it. However, often the homes most at flood risk are also the most desirable in terms of their proximity to the water, and this concurrent existence of positive water-related amenities and negative flood risk ...

[1] The concept of return period is fundamental for the design and the assessment of many engineering works. In a multivariate framework, several approaches are available to its definition, each one yielding different solutions. In this paper, we outline a theoretical framework for the calculation of return periods in a multidimensional environment, based on survival copulas and the correspondi...

Various flood resilience enhancement measures have been proposed to deal with the growing problem of urban flooding. However, there is a lack evaluation about applicability these at community scale. This paper investigates effects two types measures: engineering and adaptive measures, in order explore their effectiveness different flood-prone communities. A community-scale oriented assessment m...

Flood mapping is a vital component for sustainable land use in flood-prone areas. Due to the frequency of flood events, local authorities demand effective yet simple methods preliminary identification areas at large scales subsequently define mitigation strategies. We focus here on workflow GeoFlood, parsimonious model which uses only high-resolution Digital Terrain Models (DTMs) geomorphologic...

Mining nonmetallic sand, gravel, and river stones in a channel has previously caused damage to the itself surrounding environment. Technical studies are needed minimize mining channel. Ongkag Dumoga River is planned be location of non-metal material for gravel stone. The research method was carried out by geodesic mapping determine profile cross-section, hydrological analysis with return period...

The use of high resolution ground-based light detection and ranging (LiDAR) datasets provides spatial density and vertical precision for obtaining highly accurate Digital Surface Models (DSMs). As a result, the reliability of flood damage analysis has improved significantly, owing to the increased accuracy of hydrodynamic models. In addition, considerable error reduction has been achieved in th...

The Pearl River Delta (PRD) has one of the most complicated deltaic drainage systems with probably the highest density of crisscross-river network in the world. This article presents a regional flood frequency analysis and recognition of spatial patterns for flood-frequency variations in the PRD region using the well-known index flood L-moments approach together with some advanced statistical t...

With the increasing tendency of natural hazards, the typhoon/hurricane/tropical cyclone induced surge, wave, precipitation and river flood as extreme external loads not only menace Nuclear Power Plants (NPP) in coastal areas, but also some inland territorial NPP. For all of planned, designed and constructed NPP the National Nuclear Safety Administration of China and International Atomic Energy ...
