But they still face various forms of habitat degradation, including the draining of wetlands,
channelization of rivers and levying.
The story is similar in Mumbai, where destruction of mangroves and
river channelization have been blamed for similarly exacerbating the flood which occurred there in 2005 (also driven by rain, not storm surge, nor related to a cyclone)-- and will similarly make things worse if, someday, a cyclone causes a major storm surge there.
«Of critical note is the
massive channelization going on at the Old Garage area of Osogbo where the government is constructing a completely new bridge to put an end to the perennial flood that is peculiar to the area.
The three species of trout in question — Brooks, Rainbows and Browns — are already barely hanging on due to road building,
channelization and other man - made disturbances.
Unlike some other species, these tiddlers — of no commercial value — appear to be relatively unaffected by lake eutrophication, bank stabilization and
channelization.
«The more walls that are going up, and the man - made condensing of the water,
the channelization, I'm not saying it's not climate change, but I think this is the biggest reason why we're seeing it here.»
Technical field of expertise includes roadway and site geometrics, storm and sanitary sewer design, traffic signing and
channelization.
