This is also the case in the Department of the Cauca Valley, where the Corporación Autónoma Regional del Valle del Cauca (CVC) is responsible for the integrated management of water resources. CVC has a number of independent data feeds, models, and tools at their disposal; however, this information is often only available as static data in reports. Decisions are thus taken primarily based on such static (and often outdated) information, rather than on current data that are representative of the actual situation. CVC lacks a way to support water management decisions during periods of water scarcity and surplus, which may lead to poorly informed decision-making. CVC also needs tools to better assess and develop strategies for conjunctive water use, justify decisions made to water users, and improve stakeholder communication.
Incorporate information and instruments in decision making process
In recent years, much more data, information, and many more tools have been made available for water resources management in the Cauca Valley. However, this information and these instruments are not yet incorporated in the decision-making process due to the difficulty to access these quite technical and often poorly integrated systems. To resolve these challenges, a tool for integrated water management (Herramienta para el Manejo Integral del Agua – HERMANA) is under development that integrates different types of data, information, models and tools. This includes:
- Information from CVC’s institutional database, GeoCVC, including over 250 hydroclimatological stations and over 2,500 groundwater monitoring wells;
- Real-time meteorological, hydrological, and water quality data and forecasts from FEWS-IDEAM (using Delft-FEWS, see Werner et al., 2013);
- Surface water models (HBV, SOBEK), which are included in FEWS-IDEAM; and
- Drought indicators based on satellite data from InfoSequía
HERMANA is a web-based water information tool to support integrated water management. HERMANA displays weather and water data, generates user-defined overviews, forecasts, and warnings tailored to the needs of water authorities and their stakeholders. The HERMANA dashboards are configured via the HydroNET Water Control Room applications in which different types of data, information, models and hydro-climatological tools are combined in order to support both tactical and strategic decision-making related to water resources in Colombia. At the time of publication, the system is also being expanded to incorporate results from a numerical groundwater flow model, iMOD, which has been incorporated into a Delft-FEWS system, called FEWS-ESCACES.
