Field Testing of a Simple Flume (SMBF) for Flow Measurement in Open Channels
In this paper the stage–discharge relationship of a new flume named SMBF (Samani, Magallanex, Baiamonte, Ferro), originally proposed by Samani and Magallanez and tested by Baiamonte and Ferro, for measuring flow discharge in open channels is reviewed. The flume is obtained inserting two semicylinders in a rectangular cross section. The results of some experimental runs carried out using horizontal flumes characterized by different values of the contraction ratio (ranging from 0.17 to 0.81) are used for determining the two coefficients of the power stage–discharge equation. The stage–discharge equation is tested using flow measurements carried out in the period between December 2004 and Marc…

FIELD TESTING OF THE SMBF FLUME
At first, in this paper the stage-discharge relationship of a new flume, originally proposed by Samani and Magallanez, for measuring flow discharge in open channels is reviewed. The flume is obtained inserting two semicylinders in a rectangular cross-section. Then, the results of some experimental runs carried out using horizontal flumes characterized by different values of the contraction ratio (ranging from 0.17 to 0.81) are used for determining the two coefficients of the power stage-discharge equation. Finally, the stage-discharge equation is tested using flow measurements carried out, in the period December 2004 – March 2006 in the Sicilian experimental SPA1 and SPA2 basins. Field test…

Modelling the effects of a bushfire on erosion in a Mediterranean basin
A bushfire occurred in the Asinaro River basin in July 1998. The basin area is 55 km2 and about 74% of the whole area was set on fire. The aim of this paper is to test the influence of fire on both soil erosion and the spatial distribution of the areas characterized by the greatest sediment yield values. The RUSLE model and a spatial disaggregation criterion for sediment delivery processes (SEDD model) were used to test the effects of the bushfire. The basin was divided into 854 morphological units for calculating the topographic factor. The RUSLE climatic factor R was calculated using daily rainfall data. The soil erodibility factor was determined by sampling at sites distributed over the …
