Aproximació geogràfica als projectes hidràulics del Ter selvatà (1850-1930). Reflexions a propòsit d’un llibre recent

This contribution tries to do a geographical approach about the hydraulic works in the River Ter, in the area of the Selva county. The reflections included here are based in the considerations of the research contained in the book of the historian Gerard Buxeda recently published. The interest will be focused in the scale of the projects proposed, in the differentiation of their characteristics according to the zone where will be proposed, in the relation of these works with the policy and the ideology dominant in the state, etc. In short, the aim is to frame the hydraulic works in a larger context and with the geographical specifies during the period 1850-1930

Equivalent roughness of gravel-bed rivers

The relation between the equivalent roughness and different grain size percentiles of the sediment in gravel-bed rivers was determined under the hypothesis that the vertical distribution of the flow velocity follows a logarithmic law. A set of 954 data points was selected from rivers with gravel size sediment or larger, with a non-sinuous alignment and free of vegetation or obstacles. According to the results, the ks roughness is equivalent to approximately 2.4D90, 2.8D84, and 6.1D50. No correlation was detected between the sediment sorting and the sediment mobility index on one hand, and, on the other, the coefficient of proportionality of each grain size percentile.
