What we offer

Natural hazard and risk assessment

Spatially explicit, evidence-based risk intelligence for flood, landslide, cloudburst, and drought — enabling risk-informed decisions on where to build, where to invest, and where to reduce exposure before disasters occur.

Service overview

Across India’s rapidly urbanising landscapes, critical investment decisions — new townships, road corridors, drainage upgrades, and housing projects — are routinely made without verified knowledge of flood, landslide, or drought exposure. Risk assessments, where they exist, are often outdated, non-spatial, or insufficiently granular to condition individual site decisions. The result is infrastructure built into harm’s way, scheme funds allocated without risk context, and preparedness plans built on incomplete data.

For hill states like Uttarakhand, this is an acute and documented problem. Recent floods and landslides have caused significant loss of life and infrastructure damage in areas where spatial risk intelligence could have guided safer development.

Anora Intel provides multi-hazard risk assessments that move from susceptibility and vulnerability mapping through to integrated risk output — structured to the scale, hazard type, and decision context of each engagement.

Service modules

Flood risk assessment

Rainfall-induced inundation modelling integrating DEM, river level data, reservoir storage, rainfall, drainage networks, road network, and census data. Outputs range from a flood risk zone map to a comprehensive flood model report with river levels and reservoir storage. Reference timeline: 4 months for a basic risk map; 6–7 months for a comprehensive report at the scale of Dehradun.

Landslide susceptibility mapping

Infrastructure route planning

Slope, geology, land cover, soil moisture, historical event locations, rainfall, vegetation, and hydrological soil group combined into susceptibility, vulnerability, and hazard layers. Particularly critical for hill state satellite town siting. Typically delivered alongside flood risk assessment.

Cloudburst risk mapping

Historical cloudburst event inventory with spatial data and vulnerability assessment, generating risk zone maps with gradient scoring. Near-real-time alert system in development, dependent on meteorological inputs.

Drought monitoring

Three drought typologies covered: meteorological drought (SPI derived from IMD and ERA5 reanalysis), agricultural drought (NDVI, EVI, SMAP, MODIS), and ecological drought (LST, fire indices). Annual update cadence.

How we work

Risk assessment at Anora Intel follows a three-layer framework: susceptibility (where is the physical environment prone to hazard), vulnerability (what is exposed and how sensitive is it), and hazard modelling (what does an event look like given rainfall, terrain, and drainage). The combination produces a risk output — zone maps with quantified gradients, not simply high, medium, and low.

Satellite data sources include Sentinel-1 SAR, optical imagery, DEM, soil moisture from SMAP, and MODIS for agricultural and ecological drought. Ground data that significantly improves accuracy — drainage maps for flood modelling, soil samples for landslide susceptibility, historical event records for cloudburst mapping — is integrated where available.

Field surveys are conducted for vulnerability mapping and, where high-resolution data is required, for soil sampling. All outputs are standardised to applicable NDMA and MoEFCC guidelines, accompanied by clear methodology, assumptions, and limitations.

Risk maps are designed for periodic update. Broad zone maps update every three years or following significant urbanisation. Comprehensive flood models update annually with new precipitation data.
