Hydrology

The strategic actions in this area are as follows:

 

Surface Water Resource Program

Monitoring of Water Networks – Instalation and operation  of  hydrometeorological system, telemetry systems, water quality and sedimentometry systems, and also monitor water levels in reservoirs. Operation of  the national hydrometeorology network which comprises about 2,500 stations and 200 telemetry stations. More than 240,000 data on hydrology are collected, collated and stored each year.

Flood forecasting and flood alerts – Instalation and operation  of systems for water levels prediction and alert activation. Currently, there are systems installed for  predicting the water levels in Manaus and in the Pantanal in Mato Grosso state, and another one regarding a water level alert for the Rio Doce river basin.

Studies, Surveys and Hydrologic Mapping – Hydrology interpretation studies and theme-based hydrology maps generation. Part of the hydrologic studies are designed to support land use schemes and reduce environmental impacts in the Araranguá coal basin. Development of  systems for the integration of hydrologic data.


Groundwater Resource Program

Registration, Recuperation, Revitalization and Installation of Wells – Registration of  wells and water users. It is being completed the Resource Atlas  covering the states with a semi-arid climate. It is being commenced the revitalization and registration of wells in Rio Grande do Sul and Santa Catarina states and in the north-east of Brazil..

Hydrogeological Mapping, Studies and Surveys – Hydrogeological research and hydrogeological map in a GIS platform. Studies in small sedimentary basins in semi-arid regions of the country are carried out, as are hydrogeological studies and mapping in Rio Grande do Sul state, Jequitinhonha valley and on the southeastern edge of the Parnaíba.

Groundwater Information System - SIAGAS – Involves the collection, collation and storage of hydrogeology data in the system and its distribution to those agencies involved in hydrogeological management and use.
