Hydrology

Water resources are under immense pressure due to overuse by large-scale urbanization, industrialization and mineral exploration. Many agencies are responsible for data collection, processing and validation of hydrological data. An Integrated Hydrological Information System is needed to ensure that integrated, secure data is accessible to all these agencies and other users. Such a system provides reliable data sets for long-term planning, to design and manage water resources and ensure optimum water use.

Geospatial Solutions for Water Management

Rolta's unique GIS solutions offer a wide range of tools to manage water resources more efficiently and in a cost-effective manner. They allow:

• Assessing up-to-date and historic data to map and evaluate the hydrological / hydro-geological features of a watershed
• Identifying location-specific methodologies to assess flood / drought forecasting and occurrences
• Development of a geo-database and a hydrological information system for water resource management
• Development of a sustainable tank information system comprising of spatial and non-spatial data

Spatial Services

The vast experience and knowledge base gained by executing various projects has enabled Rolta to provide professional services in different aspects of hydrology and hydro-geology like watershed, groundwater and surface water management.

We offer solutions to help you to:

• Automatically delineate watershed regions
• Delineate sub-basins for watershed analysis
• Estimate surface runoff and compute peak flow value
• Delineate flood plains automatically
• Generate hydrographs from feature objects
• Ground water data management
• Surface water data management

Our web-enabled Hydrological Information System (map-based) and Hydrological Inventory System (text-based) helps users get up-to-date information on hydrological, hydro-geological and meteorological data. Updating data online and sharing data will make water resources management dynamic and efficient.

GIS is a very useful tool for planners and executors and can be combined with geographical as well as attribute data for visualizing, analyzing, planning, monitoring, and quick decision-making.

Applications for Water Resource Management

GIS can be used in Water Resources Management for hydrological, hydro-geological and hydro-meteorological data modeling and analysis. The application developed will enable integration and consolidation of all types of hydrological data as text data, tables, time-series, spatial data (maps) and related data for efficient, reliable and secured use.

We automate complex processes so that users are able to get the desired results with just the click of a button. Our qualified and experienced engineers provide end-to-end services for water resource management by applying the latest available technology.
