Description
The impoundment of rivers by dams is the biggest direct anthropogenic impact on the
hydrological cycle. The utility of dams, as providers of water for human consumption,
irrigation and electrical production, is undeniable. However, the price to pay, weighting benefits versus ecological impacts caused by dams, is enormous and often questionable. The deleterious ecological impacts caused by dams are detected at the dam’s site are and at hundreds of kilometers downstream from dams, even in estuaries and coastal areas. The uncontrolled water discharge from dams, both high volumes of water and inappropriate timing, compromise fish recruitment because eggs are flushed from estuarine spawning and nursery areas. Thus, our goal was to develop an hydrodynamic modelling approach that evaluates the impact of water discharge from dams on the advection of fish larval stages off estuaries and into coastal areas. This goal was accomplished by merging the abundance of anchovy eggs along the Guadiana estuary in MOHID.
