Problems solved by technology
[0003] Nowadays, many scholars have conducted on-site observations of tidal currents, waves, and sediment concentration in the coastal zone. However, since the intertidal zone is a water level fluctuation zone, the water depth is shallow and the width is large, it is difficult to go to the beach by ship survey, and it is difficult to enter the water by human survey. Complex, most field observations are single-point observations, it is difficult to obtain the synchronous changes of water and sediment movement in time and space, which limits the research on the relationship between water and sediment in the entire intertidal zone and the evolution of landforms

The invention provides an intertidal zone multi-site near-bottom boundary layer flow and sediment process synchronous observation method. The method comprises the following steps that the positions of three types of observation points are determined according to the terrains, vegetation characteristics and hydrodynamic conditions of an intertidal zone observation profile; an observation platform and needed instruments are determined according to the hydrodynamic conditions of all types of observation points; instrument supports and instruments are installed at the observation points at the intertidal flat exposure time according to the terrains and the measured tide level process of all the observation points of the intertidal zone to arrange the instruments; automatic observation and data collection are carried out according to set observation starting and ending time; the observation instruments and the supports are recycled. According to the intertidal zone multi-site near-bottom boundary layer flow and sediment process synchronous observation method, foreign advanced current meters, turbidity meters and tide level meters are adopted, and the temporal and spatial variation rules of the intertidal zone multi-site near-bottom boundary layer flow and sediment relation can be obtained.
Description
technical field [0001] The invention relates to the technical field of water-sediment observation, in particular to a method for synchronously observing the process of water-sediment in a multi-point near-bottom boundary layer in an intertidal zone. Background technique [0002] The coastal zone is the forefront of land-sea interaction, rich in natural resources, and the temporal and spatial changes of tidal currents, waves, and sediment movements in the coastal zone play an important role in the evolution of landforms. [0003] Nowadays, many scholars have conducted on-site observations of tidal currents, waves, and sediment concentration in the coastal zone. However, since the intertidal zone is a water level fluctuation zone, the water depth is shallow and the width is large, it is difficult to go to the beach by ship survey, and it is difficult to enter the water by human survey. Complicated, most of the on-site observations are single-point observations, and it is diffi...
