Harp Piemonte — gemma — geodatabase Morfology Water courses in Piedmont

the Gemma dataset, geodatabase Morfologia Corso d’Acqua, collects all the morphological information relating to the watercourses of the Piedmont region. Gemma was born as a working tool and as a support to the calculation of the IQM morphological quality indicator, an index that together with the index of alteration of the hydrological regime iari assesses the hydromorphological state of a water course as required by the Water Framework Directive 60/2000/CE WFD, transposed in Italy by Decree 260/2010 (technical criteria for the characterisation of water bodies). The service makes available some data extracted from the gem dataset.
