Water deep mapping from HJ-1B satellite data by a deep network model in the sea area of Pearl River Estuary, China

open access: yesOpen Geosciences, 2021
Remote sensing (RS) water depth inversion is an important technology and the method of water depth measurement. Taking the waters around the islands outside the Pearl River Estuary as an example, five optical RS depth inversion algorithms were introduced.

Water Depth Inversion From a Single SPOT-5 Dataset [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2016
Knowing bathymetry at intermediate depth, over large areas, and at a reasonable cost is a key issue. Spaceborne remote sensing techniques must play an essential role in retrieving such bathymetry. In this paper, a method is proposed that aims to address this issue without any in situ measurements by exploiting the characteristics of the SPOT-5 ...

A Noise De-Correlation Based Sun Glint Correction Method and Its Effect on Shallow Bathymetry Inversion

open access: yesRemote Sensing, 2022
Sun glint on the sea surface is the unavoidable noise in optical remote sensing images. Water depth retrieval based on optical remote sensing images is vulnerable to sun glint contamination.

Joint sensing of bedload flux and water depth by seismic data inversion [PDF]

open access: yesWater Resources Research, 2019
AbstractRivers are the fluvial conveyor belts routing sediment across the landscape. While there are proper techniques for continuous estimates of the flux of suspended solids, constraining bedload flux is much more challenging, typically involving extensive measurement infrastructure or labor‐intensive manual measurements. Seismometers are potentially

Underwater Topography Inversion in Liaodong Shoal Based on GRU Deep Learning Model

open access: yesRemote Sensing, 2020
The Liaodong Shoal in the east of the Bohai Sea has obvious water depth variation. The clear shallow water area and deep turbid area coexist, which is characterized by complex submarine topography.

Water Depth Inversion in Haikou Bay Based on TM Image [PDF]

open access: yesProceedings of the 2013 International Conference on Remote Sensing,Environment and Transportation Engineering, 2013
Remote sensing has been proved to be a useful technique in measuring water depth in coastal zone. This paper takes Haikou Bay as the study area. The spectral analysis of the correlation index between TM image and the observed water depth from chart is made.
