Obstacle marks are instream bedforms, typically composed of an upstream frontal scour hole and a downstream sediment accumulation in the vicinity obstacle. Local scouring at infrastructure (e.g. bridge piers) is well-studied phenomenon hydraulic engineering, while less attention given to time-dependent evolution holes boulders their geometric relations (depth width, length ratio). Furthermore, ...

The Unmanned Systems Research Laboratory (USRL) of the Cyprus Institute is a new mobile exploratory platform EU Infrastructure Aerosol, Clouds and Trace Gases InfraStructure (ACTRIS). USRL offers exclusive Aerial Vehicle (UAV)-sensor solutions that can be deployed anywhere in Europe beyond, e.g., during intensive field campaigns through transnational access scheme compliance with drone regulati...

in this research work the classification of the southern coasts of the caspian sea is performed using sedimentary and morphodynamic indices. this includes field study of morphodynamic characteristics of the shore structures. field measurements include in situ samplings of sediments and actual observations of structures on site. these field activities were done along six transects in the dry coa...
