Hongke case study on storm impact in coastal areas of North Carolina using lidar

Sea level rise and violent storms threaten coastal areas all over the world , It will cause floods and erosion of the coastline . Study and understand storms , In order to predict their impact on barrier islands and coastal areas , So as to take appropriate protective measures .

Ryan Mieras The University of North Carolina at Wilmington, led by Dr (UNCW) The team uses Hongke solid-state lidar HK Cube 1 Conduct in-depth research in this field . Their goal is to develop a measurement system that can be quickly installed on the beach , To measure the water level remotely 、 Evolution of beach profiles during waves and storms .

As a multi agency 、 Academic and non-governmental organizations (NGO) Collaborative community DUNEX Part of ,Mieras Doctor Yu 2021 year 8 At the beginning of this month, Hongke solid-state laser radar was deployed HK Cube 1 Sensor two weeks , Collect data about changes , Observe the beach profile of a coast in Dakota, North Carolina 、 Waves and water levels . The requirements are multifaceted , It is necessary to record the shoreline changes that take place in a longer time and a larger spatial dimension , It should also be able to record the data of wave profile quickly and continuously in a narrow space .

“ We are currently testing how to best integrate Hongke solid-state lidar HK Cube 1 Configurable scan mode for these different requirements ,”Mieras The doctor reported that .“ The flexibility of sensor configuration and installation is a major advantage , And the data accuracy is high .”

In addition to flexible scanning mode configuration ,HK Cube 1 The sensor can reliably and stably capture 3D data . Compared with the camera , Lidar data provides additional dimensions （ distance ）, And not affected by bad lighting conditions or darkness . therefore , It is very promising in the application of coastal remote measurement system .

“ The goal is to develop an affordable and scalable remote sensing platform , To measure the impact of storm surges on coastal areas ,”Mieras say .“DUNEX Provide human and operational resources and support , Plus the expertise of researchers , It is the perfect framework to promote development and research .”

Install a remote measurement system on the beach in North Carolina

except DUNEX,Mieras We will continue to cooperate with relevant researchers .Mieras Express , Their next steps include “ comprehensive 2021 year 8 Data collected during the monthly pilot activities , Then develop the algorithm , Filter the data and detect the distance of each wave across the beach , And the amplitude and time of the beach altitude change .”
