Modeling hydrology

Description

We will use an appropriate physically-based model (e.g. CASC2D) to simulate distributed hydrologic response over a long period of time, e.g. 40-80 years. The hydrologic model CASC2D will be calibrated to several catchments representing the main regional differences in hydrologic activity across Sweden using the recent historical daily time-step data available.

CASC2D is a state-of-the-art hydrologic model that takes advantage of recent advances in Geographic Information Systems (GIS), remote sensing, and low-cost computational power. Hydrologically active areas (HAA) relationships will be developed by correlating a static proxy parameter (or set of proxy parameters) to monthly estimates of hydrologic responses as determined by the distributed hydrologic model. Combinations of relevant management measures and scenarios will then be tested using CASC2D modeling against selected climate-change scenarios. In addition, depending on identified stakeholder needs, it will be possible to simulate hydrologic responses given a certain design storm or return period (e.g. 50-yr) event (as are often used in road infrastructure designs).
