combe martin�*s problems have attracted an innovative project, using cutting—edge technology to try toge wifi network. every hour, they send in data on six key indicators — a snapshot of the health of the water. what would you expect to see here if, for example, sewage was being discharged upstream? yeah, so we would see spikes in things like ammonia and ph, and we can also then cross—reference that with temperature and dissolved oxygen levels. so you�*d have a pretty clear indication almost immediately that something was going wrong? yeah, exactly that. the information from the sensors is then combined with satellite imagery to see in advance if, for example, a farmer is about to unwittingly pollute the river. we can see where people have actually put certain stuff on the fields that are changing the growth pattern and, actually, you know, are they putting too much on the field? is it too rich that�*s washing off into the systems? you know, we can detect all those sort of things from space. computer systems company cgi developed the artificial intelligence part of the project, uploadi
