In this study, we propose a new Rapid Flood Inundation Model (RFIM). The purpose of the RFIM is to generate predictions of water depth and flood extent using less computer resource than required by two-dimensional shallow water equation models (SWEMs). To be useful the RFIM must produce predictions that are comparable with those obtained from SWEMs. The model described here is an improvement on...

My work within a research project studying flood-risk management in Hungary is described, with special attention on loss-spreading instruments, mainly insurance. I argue that computer simulation tools are useful in catastrophe policy making. Computer simulation provides a method for estimating the consequences of different potential policy strategies. In decision making processes it also forces...

An unbiased estimate of the arithmetic mean of the He/He ratio (R) of basalts from the global spreading ridge system is 9.14 + 3.59 Ra (n=503), where Ra is the atmospheric ratio and n is the number of data points. The + two standard deviation (2σ) range covers much of the oceanic island and continental flood basalt data that have been attributed to ‘plume’ or ‘lower mantle’ components. The high...

this paper attempts to examine the effect of water spreading on soil physico-chemical properties, and vegetative characteristics of common mesquite. for this, on the basis of flood water discharge, three sections of lands were accurately selected at kosar water spreading experimental station, in tangestan, bushehr province. in each section, 6 profiles were digged out and studied; meanwhile soil...

the multi-criteria decision making model is an important tool for decision making in water resource management. in this paper, the topsis model was used to rank seven flood management options in the gorganrood river flood management project, including conservation of natural condition, golestan reservoir management, levee construction, diversions-channel construction, flood forecasting and warn...

Biodiversity declined markedly over the past 150 years, with the biodiversity loss in fluvial ecosystems exceeding the global average. River restoration now aims at flood safety while enhancing biodiversity and has had success locally. However, at the scale of large river distributaries, the recovery remained elusive. We quantify changes in biodiversity of protected and endangered species over ...
