Making sure your teams understand and can apply best practices is an essential strategy to get the most value from the Hydro-BID platform. The IDB provides face to face and online training courses to support professionals in the water management field, and others acquire the knowledge and skills needed to efficiently run Hydro-BID.
For now, you can review the technical notes with the description of: (i) Analytical Hydrology Dataset for Latin America and the Caribbean (LAC-AHD); (ii) System functionality/usage of Hydro-BID; and (iii) New Functionalities (Reservoir, Sediment and Groundwater Simulation Modules).

1) Analytical Hydrology Dataset (AHD) for Latin America and the Caribbean
The Analytical Hydrology Database (AHD) is a spatially explicit (i.e., geographic information
system [GIS]-based) database of surface water. It serves as a regional spatial data platform for
integrating the disparate data needed to support regional hydrography models. It provides a
framework for parameterizing models in a consistent way, provides the upstream/downstream
flow connectivity necessary for the models, and provides the data necessary for displaying
results in map form.
The AHD has four key features enabling the development and implementation of tools that
analyze water in the context of its movement in a network:
- a nested polygon catchment structure with a unique catchment identification scheme
- a corresponding line structure for the stream segments contained within the catchments
- descriptive attributes that create a linked network of upstream and downstream stream segments and catchments
- database structure for populating and attaching additional model-specific attributes

2) Hydro-BID: An Integrated System for
Modeling Impacts of Climate Change on
Hydro-BID is built on an Analytical
Hydrographic Dataset (AHD) for the Latin American and Caribbean region. The AHD is
described in detail in the previous Technical Note of this series.
Hydro-BID utilizes the data structure and the catchment and stream network topologies of the
AHD. It incorporates data on land uses, soil types, rainfall and temperature within the study area,
as well as observed stream flows for use in calibration. Hydro-BID includes a pre-processor
interface to disaggregate monthly climate data into a daily time series of temperature and
rainfall, which is the required form of climate data input. The system applies a standard
Generalized Watershed Loading Function (GWLF) model, coupled with a novel lag-routing
methodology. Model output is generated as a time series of projected water
flows, at either a daily or monthly scale. The system has a graphical user interface to accept
model input, as well as to display graphical and tabular summary outputs.

3) Hydro-BID: New Functionalities (Reservoir, Sediment and Groundwater Simulation Modules)
In the current version of Hydro-BID, additional modules are implemented. These modules work seamlessly with the original rainfall-runoff model once the modules are selected to be included in the simulation. The three modules are 1) reservoir simulation, 2) sediment transport and 3) surface and groundwater interaction using MODFLOW. While the first two modules are integrated within the Hydro-BID model, the surface water and groundwater interaction module requires an external groundwater model, MODFLOW. The link between Hydro-BID and MODFLOW is achieved through running the two models sequentially and sharing input/output data files.
In addition to the new modules, the graphical user interface (GUI) of Hydro-BID is greatly enhanced. The enhancement includes grouping tasks into tabs of model setup, calibration parameter savings, and special tools, as well as extensive graphical viewing of outputs. We have added more graphical and statistical output displays to enable calibration and validation of model simulations. Model output is generated as a time series of projected water flows, at either a daily or monthly scale. The system has a GUI to accept model input, as well as to display graphical and tabular summary outputs.
