Developers: King's College London (models), AmbioTEK (software)

Audience: Conservation and development NGOs, GO and NGO Policy analysts, agriculture and industry (e.g. extractives), education and academic research.

Focus: WaterWorld is a testbed for the development and implementation of land and water related policies for sites and regions globally, enabling their intended and unintended consequences to be tested in silico before they are tested in vivo. WaterWorld can also be used to understand the hydrological and water resources baseline and water risk factors associated with specific activities under current conditions and under scenarios for land use, land management and climate change. It incorporates detailed spatial datasets at 1-square km and 1 hectare resolution for the entire world, spatial models for biophysical and socio-economic processes along with scenarios for climate, land use and economic change. A series of interventions (policy options) are available which can be implemented and their consequences traced through the socio-economic and biophysical systems. The model integrates with a range of geobrowsers for immersive visualisation of outcomes.  

Though we provide input data for application of this model anywhere globally (from remote sensing and other global sources) users can also use this model with their own datasets.  Application with the provided datasets takes only half an hour and requires no GIS capacity.  Bringing in your own datasets will take much longer depending on the availability, level of processing, format and consistency of those datasets and also requires GIS capacity.

Typical applications include, water resources assessment, water security analysis and hydrological ecosystem services accounting.  Also climate impacts analysis and land and water management. WaterWorld connects with the following tools: WEAP, AQUEDUCT, TESSA.





Geographical coverage: global

Spatial resolution: 10 degree tiles @ 1km resolution or 1 degree tiles @ 1-hectare resolution. Globally applicable, locally relevant. Also global 10km, continental 1km (not possible on public servers)

Temporal resolution: Monthly for baseline (1950-2000) and scenario

Development status: 
History: TAMMOD developed 1998, modified for FIESTA model 2004, modified for AGUAANDES 2007 and then WATERWORLD 2008
Version 1: complete 
Version 2: ongoing - Let us know of new features you would find useful

Versions:
The version 1 model has a basic water balance (wind driven rainfall+fog - actual ET accumulated downstream as runoff) with land use and climate scenarios, see here

Version 2 has all the components of version 1 but also incorporates soil erosion, transportation, deposition and a snow and ice model as well as policy options for land management, see here

Version 3 is in development and contains all the components of version 2 and also a subsurface stores and fluxes module.


Documentation: Model and data documentation for version 1 can be found here and system (interface and functionality) documentation is here. A presentation on the science behind the PSS can be found here (English) and here (Spanish) [opens in Google docs viewer].
