This paper focuses on an overview of kernel density estimation especially for what concerns the choice of bandwidth and intensity parameters according to local conditions. A case study inherent seismic risk analysis of the old town centre of Potenza hilltop town has been discussed, with particular attention to the evaluation of the possible local amplifying factors. This first integrated applic...

We present preliminary results of an Earth observation approach for the study of past human occupation and landscape reconstruction in the Central Sahara. This region includes a variety of geomorphological features such as palaeo-oases, dried river beds, alluvial fans and upland plateaux whose geomorphological characteristics, in combination with climate changes, have influenced patterns of hum...

The topography of a catchment has a major impact on the hydrological, geomorphological. and biological processes active in the landscape. The spatial distribution of topographic attributes can often be used as an indirect measure of the spatial variability of these processes and allows them to be mapped using relatively simple techniques. Many geographic information systems are being developed ...

Within fluvial systems, the spatial variability of geomorphological characteristics of stream channels and associated streambed properties can affect many biogeochemical processes. In agricultural streams of the midwestern USA, it is not known how geomorphological variability affects sediment denitrification rates, a potentially important loss mechanism for N. Sediment denitrification was measu...

Geomorphological processes sculpt the shape of our everyday landscapes and must therefore be simulated to generate plausible digital landscapes. In particular, topological changes must be taken into account during the formation of complex geometries such as natural arches, bridges or tunnels. We present a novel approach to simulate the geomorphological evolution of a 3D terrain represented as a...

The most widely and popularly used method for prediction of flood hydrograph resulting from a known storm in a basin area use historical rainfallrunoff data and unit hydrographs derived from them. These procedures are highly unreliable due to the climatic and physical changes in the watershed and their implementation to ungauged catchments. The use of physically based rainfall-runoff estimation...

Future global warming has a number of implications for fluvial geomorphology because of changes in such phenomena as rates of evapotranspiration, precipitation characteristics, plant distributions, plant stomatal closure, sea levels, glacier and permafrost melting, and human responses. Potential changes in rivers are outlined in this review in the context of changes in the intensity of rainfall...
