From the ground of the Good Geo Expo in Korea this week: UCON Techniques Remo-SV and mapping providers supplier Hojung Options are working to deal with water high quality in Bangladesh, in a venture for the Bangladesh Ministry of Water (CEGIS) Middle for Environmental and Geographic Info Providers.

Flood Administration, Air pollution Monitoring

Identified for its lush greenery and quite a few lakes and rivers, Bangladesh’s waterways are a treasured useful resource.  Bangladesh depends on its rivers for transportation, potable water, and meals. The rivers and lakes that give Bangladesh its distinctive topography additionally pose a periodic danger.  Between June and October, rivers generally overflow their banks and inundate the countryside.  As Bangladesh turns into extra industrialized, air pollution – each generated from home factories and from these of its neighbors upstream – threatens the water high quality.

The group at Hojung Options, working with their companions at UCON Techniques, have are utilizing the Remo-SV aquatic drone to deal with water air pollution and flood planning of the rivers.  The sensors on the Remo-SV measure temperature, salinity, oxygen ranges, and extra within the water.  Because the drone travels a predefined mission path, it may possibly pattern frequently, and in locations not often reachable by boat, explains Sunho Shin, Assistant Supervisor at Hojung Options.

“Temperature is actually essential, since you need the maximal circumstances for fish: and salinity and oxygenation decide if the water is drinkable, or can be utilized for agriculture,” Shin explains.  “We monitor electrical present, Ph, and different chemical compounds like ammonia within the water.”

“Water high quality is one thing that engineers in Bangladesh have completed for years: however historically, it’s completed by manually measurements level by level.  With the aquatic drone, engineers can take extra samples, extra rapidly.” Hojung trains native employees in order that the venture can proceed after expertise switch.  Because the Remo-SV travels, it’s taking depth measurements.  The depth measurements will likely be used to mannequin the ground of the waterways for higher flood prediction and simulation, defending the soil and probably saving lives.

Making Aquaculture Extra Environment friendly

Along with touring rivers and lakes, Hojung works with the Bangladesh Division of Fisheries, Ministry of Water Sources to assist make aquaculture farms safer and extra environment friendly.

“For fisheries, the Remo-SV might be be used to measure water high quality and stop overfeeding,” Shin explains.  “You’ll be able to monitor the water high quality and estimate how a lot feed you want for the fish.  Overfeeding causes pointless air pollution within the water, affecting native agriculture – and likewise prices some huge cash.”  With efficient water sampling, the fisheries can work extra effectively, securing the meals provide for one of many world’s most populous nations.
