Better explanation ... Impossible.... 

The U.N.-backed project, called Seabed 2030, is urging countries and companies to pool data to create a map of the entire ocean floor by 2030 which will be freely available to all. “We obviously need a lot of cooperation from different parties – individuals as well as private companies,” said Mao Hasebe, project coordinator at the Nippon Foundation, a Japanese philanthropic organization supporting the initiative. The project, which launched in 2017, is expected to cost about $3 billion. It is a collaboration between the Nippon Foundation and GEBCO, a non-profit association of experts, which is already involved in charting the ocean floor. The end result would be greater knowledge of the oceans’ biodiversity, improved understanding of the climate, advanced warning of impending disasters, and the ability to better protect or exploit deep-sea resources, said Hasebe. High tech sonar technology will be put into use to map the whole ocean floor. “With advanced sonar technology it really is like seeing. I think we’ve come out of the era of being the blind man with the stick,” said Robert Larter, a marine geophysicist at the British Antarctic Survey. “We can survey much more efficiently – and, not only that, but in much greater detail,” he further added.   source: https://www.geospatialworld.net/news/the-un-backed-seabed-project-aims-to-create-entire-ocean-map-by-2030-to-explore-deep-sea-resources/

do you have basic with any software involving this modelling/analysis steps? we can start from it everyone will give you different scenarios based on their expertise with their own softwares for me, as a GIS-er then ArcGIS with plugin for hydro analysis like ArcHydro or HECgeoRAS will do the job so tell us little bit more details in here 😁

Did you find solution or you need it till date?

Hi comrades, I have been searching for a solution to deal with a problem but this is not my cup of tea so could use some help from the experts here. I am looking for software that can best deal with cross- and long-sections of river systems. Vectorworks was recommended by a friend but it involves a learning curve to master it. CAD software ( AutoCad or related) might handle that kind of task but I am not an avid user. Ideally, I would like to use temporal data of two time periods to compute the erosion and deposition along the riverbed. If anyone could kindly point me to the right software or resources, it will be fantastic. Thanks in advance
