This study aims at providing expertise for preparing public-based flood mapping and estimating flood risks in growing urban areas. To model and predict the magnitude of flood risk areas, an integrated Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) analysis techniques are used for the case of Eldoret Municipality in Kenya. The flood risk vulnerability mapping follows ...

In recent years, through the availability of remotely sensed data and other national datasets, it has become possible to conduct national-scale flood risk assessment in the England and Wales. The results of this type of risk analysis can be used to inform policy-making and prioritisation of resources for flood management. It can form the starting point for more detailed strategic and local-scal...

Large-scale floods have the potential to generate substantial economic losses. Within Europe, governments have dealt with these losses in different ways, which may or may not have enhanced adaptability of their societies. In this research we develop a classification of insurance and compensation systems to deal with losses from floods. We suggest that, from the perspective of adaptive capacity ...

Determination of reliable crystallization ages by K-Ar methods for young (<1 Ma), fresh basalts from the seafloor has been frustrated by several effects. The small amounts of radiogenic 4øAr developed over these timescales in such 10w-K rocks are difficult to resolve from predominantly atmospheric 4øAr. An additional concern is that mantle-derived 4øAr may not be totally outgassed when magmas q...

Flood disaster is considered as a major natural hazard due to its devastatingeffects on the affected areas. Determining the flood vulnerable areas is important fordecision makers in order to perform planning and management activities. GeographicalInformation System (GIS) is integrated with Multi Criteria Decision Analysis (MCDA)used to analyze the flood vulnerable areas. The aim of this researc...

Haleakala volcano on East Maui, Hawaii, consists of a tholeiitic basalt shield which grades into a younger alkalic series that was followed by a post-erosional alkalic series. Fresh, stratigraphically controlled samples from the three volcanic series were analyzed for major element abundances, Sr and Nd isotopic ratios and trace element (K, Rb, Sr, Ba, Th, Ta, Nb, REE, Hf, Zr, Sc, V, Cr, Co, Ni...
