Environmental assessments

Water quality and human interventions in coastal and riverine areas are correlated. A healthy environmental ecosystem strongly depends on water quality. Beach nourishment, dredging, disposal of wastewater, and drilling are examples of activities that (locally) affect the temperature or salinity of water, the turbidity, the concentration of certain particles, or the sedimentation on the seabed. With regard to the impact on the environment, the magnitude of these effects is important.   

Royal HaskoningDHV seeks solutions for existing and potential water quality issues. We use numerical water quality models to predict spreading and/or sedimentation of the substance in question. In close consultation with ecological experts, we translate the magnitudes of concentration or sedimentation into environmental impact and threshold values. In our multidisciplinary team we seek for alternative ways of intervention to prevent or mitigate potential issues.
