The use of micromobility vehicles is considerably growing in cities worldwide. As a result, crashes involving these are also increasing, with single-bicycle accounting for significant percentage. In most infrastructure-related crashes, the road surface was slippery. this context, study pavement skid resistance crucial to improve safety. research, British pendulum tester used test 5 different ty...

The development of coastal regions combined with rising sea levels is leading to an increasing risk flooding caused by wave overtopping natural beaches and engineered structures. Previous measurements have been obtained for static structures using fixed current meters depth sensors or tanks. These are unsuitable dynamically stable protection however, because the geometry these expected evolve u...

Abstract Hard rock blocks embedded in a soft matrix can be found many geological units. When tunneling these heterogeneous formations, technical problems caused by the presence of cobbles and boulders. These risks depend on excavation method selected, typically increase as block content, dimension frequency increase. Therefore, successful projects require cobble-boulder properties to accurately...

Litter on beaches is one of the most difficult problems in coastal management and every year, much efforts public money are invested to try alleviate solve problem. Cigarette butts (CB) among widespread abandoned personal items world. In Spain, they found all types beaches, where discarded by beach users; however, rivers streams can also deposit CB shores. This paper analyses abundance differen...
