Project Description

Project objectives

The overall objectives of HYACINTS are to establish improved tools and methodologies for assessing effects of climate change on water resources at both regional and local scales and to test these on cases relevant for the water supply sector in Denmark and for an international case relevant for export of Danish water resources management expertise. The specific scientific objectives are:

  • To make a full dynamic coupling of a climate model code (HIRHAM) and a distributed physically based hydrological model code (MIKE SHE).
  • To further develop precipitation downscaling and bias correction methods when converting climate model results to hydrological model inputs.
  • To develop grid refinement methods for hydrological models and methodologies for optimal conceptualisation, simulation and downscaling of complex geological environments.
  • To develop new methods for estimation of precipitation from remote sensing data, particularly aimed at mountainous regions with poor data coverage.
  • To establish a coupled climate-hydrological model for the entire Denmark based on the regional climate model HIRHAM and the MIKE SHE based national hydrological model (DK-model) and to assess the hydrological change at local scale at selected cases.
  • To assess the uncertainties related to prediction of climate change effects on water resources at local scale, including all sources of uncertainty (climate scenarios, model structure, geological interpretations, model parameters and adaptation strategies).

Expected output

The intention of the present project is to develop the scientific basis for the next generation of hydrological impact assessment methodologies caused by future climate changes. The project will provide the foundation for operational hydrological change assessment with higher accuracy and better precision than previously developed.
