Central Ground Water Authority: CGWA NOC & Groundwater Permission

Image
Groundwater is an important source of water for residential, commercial, industrial, infrastructure, and other projects. When a project plans to extract groundwater, understanding the applicable approval process is essential before using a borewell or other groundwater source. The Central Ground Water Authority plays an important role in regulating groundwater extraction and related permissions in India. Depending on the project and its location, applicants may need to obtain a CGWA NOC or comply with applicable groundwater regulations. The process can involve reviewing site conditions, assessing groundwater availability, preparing technical documents, and submitting the required information through the appropriate process. Understanding these requirements early can help project owners avoid delays and make better decisions about groundwater use. What Is the Central Ground Water Authority? The Central Ground Water Authority, commonly known as CGWA, is responsible for regulating and ma...

How Satellite Data Helps Identify Flood-Prone Areas with Satellite-Based Flood Modelling

Image
Floods can develop quickly, but the areas most likely to be affected can often be identified in advance with the right data. Satellite imagery provides a wider view of land, water bodies, drainage patterns, terrain, and changes in surface conditions, making it useful for understanding potential flood hazards. Satellite-based flood modelling combines satellite observations with geographic, rainfall, terrain, and hydrological information to understand how water may move across a landscape. This approach supports Flood Mapping, planning, and Flood Risk Assessment for cities, infrastructure projects, agricultural areas, and vulnerable communities. What Is Satellite-Based Flood Modelling? Satellite-Based Flood Modelling uses information collected by Earth-observing satellites to study flood-prone locations and possible inundation patterns. Satellite images can show changes in water extent, land cover, vegetation, soil conditions, and drainage features over large areas. The information can ...

Reservoir Hydrological Survey and Water Resource Assessment

Image
Reservoirs play an important role in water storage, irrigation, drinking water supply, flood management, and industrial requirements. Understanding how water enters, moves through, and leaves a reservoir is essential for effective water resource planning. A Reservoir hydrological survey provides the technical information needed to evaluate these water-related conditions and support informed decisions for different types of projects. Hydrological assessment also considers rainfall, runoff, river flow, catchment characteristics, evaporation, and seasonal changes. When these factors are studied together, project teams can better understand the availability and behaviour of water within a reservoir system. What Is a Reservoir Hydrological Survey? A Reservoir Hydrological Survey is a systematic study of the hydrological characteristics associated with a reservoir and its surrounding catchment. The assessment generally involves collecting and analysing information related to rainfall, strea...

Flood Inundation Mapping for Solar Parks in India

Image
Solar parks require large areas of land and significant infrastructure, including solar panels, electrical equipment, access roads, drainage systems, and transmission facilities. Since these projects are often developed across open and relatively large landscapes, understanding potential flood exposure is an important part of site planning and risk management.  Flooding can damage equipment, affect site access, interrupt power generation, and increase maintenance requirements. Flood inundation mapping for solar parks in india helps identify areas that may be affected by floodwater under different rainfall and hydrological conditions.  It provides a spatial understanding of how water may spread across a project area and supports better decisions during site selection, design, and development. What Is Flood Inundation Mapping? Many people ask what flood inundation mapping actually means and how it can support infrastructure planning. Flood inundation mapping is a process used t...
