Environmentally, however, the effects of regulation include the disruption of flows and sedimentation downstream due to the construction of dams, long term siltation and consequent aggradation upstream of dams, bank erosion in the first few years after regulation, and some indefinite sedimentary redistribution, salinity, reversal of peak flows (naturally peak flows are in winter; when regulated peak flows occur in summer), and the potential for temperature fluctuations and the transfer of biota due to inter-divisional transfers (Walker, 1985, p.
