D-Hydrology

This module contains a library of (1) lumped hydrological models from polder sub-catchment scale up to river catchment scale, such as HBV and SCS and (2) the fully distributed hydrological model: wflow.

Lumped models

The catchment areas can easily be modelled in a lumped or detailed manner with no restriction to the number of catchment areas. The catchment areas can be modelled in any detail using land elevation curves, soil characteristics, land cultivation, drainage characteristics etc. It distinguishes between various rainfall run-off processes such as surface run-off, sub-soil drainage and storage in saturated and unsaturated areas, taking crop evaporation and capillary rise into account. The D-Hydrology module uses separate storm events or long time series of meteorological data for statistical analysis. You can input your own rainfall patterns or use historical data and model any number of rainfall gauges taking the spatial variation into account. It can model both flood events and dry spells. This module can be used in combination with the D-Flow FM module and the D-Real Time Control module. The D-Hydrology module can also be used as a stand-alone, using reservoir approach for open water flow.

Fully distributed hydrological model: wflow

wflow is Deltares’ hydrological modelling solution for simulating catchment processes, allowing users to account for precipitation, interception, snow accumulation and melt, evapotranspiration, soil water, surface water and groundwater recharge in a fully distributed model. Successfully applied worldwide for the analysis of flood hazards, drought, climate change impacts and land use changes, wflow is growing to be a leader in hydrology solutions.
