Using the GPS Station to Study Wind and Coastal Morpho-dynamics in North-eastern Morocco DOI:  https://doi.org/10.30564/jgr.v6i1.5270 Abstract The purpose of this work is to evaluate the potential of Global Positioning System (GPS) measurements for the monitoring of aeolian and coastal dynamics. The studied sites are the Moulouya estuary, Bouarfa’s area and Tigri Chott. The study shows that GPS is used to determine the dune kinematics and the Moulouya estuary in 3-D with an annual temporal resolution and a sub-centimeter accuracy. The GPS measurements carried out between 2013 and 2021 have shown spatial and temporal variations of the dune kinematics and Moulouya estuary. The results presented here show that the GPS measurements have the capability of continuously surveying the geomorphological entities’ kinematics with small and slow displacements and thus, they could complement conventional topometric techniques in a warning system.

Effect of Precipitation Characteristics on Spatial and Temporal Variations of Landslide in Kermanshah Province in Iran DOI:  https://doi.org/10.30564/jgr.v2i4.1818 Abstract Landslide can be defined as the mass movement of sloping slopes underthe influence of mass gravity and its stimuli such as earthquakes, floodsand flood plains. This phenomenon is one of the natural hazards thatevery year causes a lot of financial and financial losses in mountainous,rain-fed and seismic areas. Detection of time and the magnitude of landslides are necessary to understand the causes of landslide and to warnpotential hazards. In this research, the amount of landslide displacementin Kermanshah province was evaluated by the characteristics of rainfall.To this end, a network of fixed points in and out of the slipping mass of20 points was created to monitor the amount of displacement on differentslip load users and the amount of displacement of each point in 5 timeintervals using the Global Positioning ...
