Our story

Built on one conviction: flood risk should never be a surprise.

Flood risk was being treated as a checkbox — a report produced to satisfy a regulatory requirement, ticked off and filed, with little connection to the engineering decisions it was meant to inform. The assessments reaching lenders and planning authorities were frequently generic, poorly calibrated to local conditions, and structurally incapable of withstanding technical scrutiny.

We built HYDRisk to treat flood risk as engineering. That means site-specific methodology, regional data calibration, and audience-structured reporting — every time, for every project. The same engineer who scopes the study delivers it and answers the regulator's queries afterwards. No open-ended billing. No handoffs. No reports that disappear into a drawer.

Our core team draws on the engineering rigour of India's premier technical institutions, combined with real-world project experience across the United States, Europe, the Middle East, India and South-East Asia — from utility-scale solar in Washington State to a 1.2 GW development in Serbia.

Why we exist
"Flood risk was being treated as a checkbox. We built HYDRisk to treat it as engineering."
60+ studies led by our founder
15+ countries worked in
Every report structured for its reviewer first
4 continents covered
01
FOUNDATION
HYDRisk established
Founded with a single focus — specialist flood risk and hydrology consulting. India as the primary market, solar and infrastructure as the primary sectors.
02
EXPANSION
International — USA, Europe & the GCC
Extended practice beyond India to the United States, Europe and the GCC — delivering hydrology and flood-risk studies for solar and infrastructure clients in Washington State, Serbia, the UAE, Saudi Arabia and Oman.
03
SOLAR FOCUS
7.5GW+ solar capacity assessed
Became a specialist provider of bankable solar PV flood risk assessments — methodology accepted by IFC-aligned lenders and EPCs across India and the GCC.
04
CLIMATE RESILIENCE
CMIP6 climate risk integration
Incorporated CMIP6 climate projections as standard in all long-lifetime infrastructure assessments — ahead of IFC and Equator Principles making it mandatory.
Principle 01
Rigour before speed
We will not compromise methodology to meet an unrealistic deadline. We set honest timelines and hold to them.
Principle 02
Regional specificity
IMD for India. GSMaP for the GCC. CMIP6 calibrated to each geography. Never one methodology regardless of location.
Principle 03
Accountability after delivery
Regulator queries, lender TA clarifications and revisions are handled by the same engineer. Included, not charged.
How we model it

We don't deliver a map. We deliver a defensible model.

Every study resolves flood depth, velocity and extent at the parcel scale, for return periods from RP2 to RP500 — then re-runs the whole thing under CMIP6 climate scenarios. Drag the return period below to see how extent grows.

Our goals

What we are building — and how we measure it.

These are not marketing statements. They are the standards we hold ourselves to on every project — and the direction we are moving in as a practice.

01
Built for first-submission acceptance
Every report is structured against the specific requirements of the lender, regulator or planning authority it is written for — before a model is run. That is how submissions are made to land first time.
02
Deepen regional expertise everywhere
IMD rainfall, CWC discharge, NDMA guidelines for India. GSMaP, wadi hydrology and UAE Municipality requirements for the GCC. We invest continuously in the knowledge that makes studies irreproachable.
03
Make climate-adjusted risk standard
CMIP6 projections are already standard in every HYDRisk study for long-lifetime infrastructure. We are working to make this the market expectation — not an optional add-on — across India and the GCC.
04
Be the consultancy clients return to
Our target is a 70%+ repeat engagement rate — clients who commission their first study and return for every subsequent project. Repeat business is the only honest measure of satisfaction.

Our commitment to every client

Fixed-fee pricing agreed before any work begins. One named engineer from brief to delivery and beyond. Post-delivery support — regulator queries, lender TA clarifications, revisions — included as standard. No surprises, no scope creep, no handoffs.

Quality assurance — four stages

QA 01
Model validation
All models validated against observed data before results are accepted.
QA 02
Regulatory checklist
Each report checked against its target authority's specific requirements before submission.
QA 03
Independent review
Internal technical peer review of methodology, results and conclusions before delivery.
QA 04
Client clarity check
Executive summary reviewed for non-technical clarity so every stakeholder can act.
How we work

One named engineer behind every HYDRisk study.

A simple model — the person who scopes your project is the person who delivers it. No account managers, no junior handoffs, no surprises.

Named on the front page
Every report carries the name of the engineer who produced it. Accountability is not delegated, and it does not expire when the invoice is paid.
Support that outlives delivery
Regulator queries, lender TA clarifications and design-team questions are answered by the same engineer, as part of the standard fee, for as long as the study is in use.
Built for four regulatory worlds
FEMA in the USA, the Floods Directive in Europe, wadi hydrology across the GCC and CWC and state frameworks in India — each handled to its own standard, not a generic template.
Team
