WaterWare embedded models

WaterWare is a modular client-server system.

Its central Water Resources Model, WRM, dynamic water budget model is based on a topological network structure of NODES and REACHES.


Generic pre-processor models, their output is used over the entire network are the prognostic non-hydrostatic numerical weather foreacast models (MM5 or WRF), that provide temperature and precipitation, but also humidity, wind data, soild moisture, solar radiation) at an hourly and 1-3 km spatial resolution over the model domain.

Within the WRM network, NODES of several types have their simple behavioural repertoire. This primarily defined by time series water flow, either as

  • input to the network (START NODES, reservoir release/outflow)
  • abstractions from the network (and or any underlying aquifers) for DEMAND NODES, where part of the abstraction is used (consumptive use), part is returned to the network (return flow). For any and all NODE types (and in principle, the reaches as well, e.g., lateral inflow, groundwater interaction, and evapotranspiration due to bank vegetation) external or "embedded" models can be used to calculate these time series with a more detailed representation of the driving processes.

    Specific models, that can also be run as stand-alone models in their own right, include:

    • a dynamic rainfall-runoff model for upstream catchments, feeding START NODES;
    • an irrigation water demand model, that estimates supplementary irrigation water edmand for irrgation districts;
    • other embedded models (not used as stand alone tools) include:
      • urban water demand estimation
      • farm water demand estimation
