Eesa07h3 f: lecture 8 - humans and aquatic ecosystems: finding the right balance & Define the major human modifications to aquatic ecosystems. Define solution techniques for urban stream syndrome . 4 ways that the activities in figure 1 have or could manifest at a global scale: anthropogenic redistribution of water on earth has led to a redistribution of mass that has affected the earth"s axis of rotation. It has resulted in a decrease in day length by 8 milliseconds: changing distribution of water has implications for the rate of sea level rise. Water that seeps into groundwater or is stored into reservoirs leads to a drop in sea level. Return flows from non consumptive uses can change the magnitude and timing of river flows. This is most dramatic for interbasin transfers where the return flow is being discharged into a different basin than it came from. Dams and reservoirs: aging of continental runoff.
