Field Research
Monitoring active research locations with real time satellite synchronization.
Keep in mind: Cloudy conditions can prevent satellite images from being captured.
The map showcases chlorophyll-a concentration in water bodies which is a key indicator that shows the amount of algae in the water, used to track water quality and spot potential algae blooms.

How I calculate these scores
The swimming suitability score (0–100) evaluates several scientific water quality parameters. The final score is an average of sub-scores based on:
-
Algae Levels (Chlorophyll-a) Indicates phytoplankton presence.
-
Water Clarity (Kd490) Measures light attenuation and turbidity.
-
Suspended Matter (TSM) Tracks suspended particles in the water.
-
Trophic State Index (TSI) Evaluates overall biological productivity.
80–100: Good
50–79: Fair
0–49: Poor
Immediate Hazard Override: If localized extreme alerts are detected (such as severe algae blooms, extremely high suspended matter, or dangerously low water clarity), the water body is immediately flagged as Poor regardless of the average measurements.

Remote sensing and hydrobiological analysis for practical water challenges
Each engagement starts with the management question. I then select suitable satellite, field, and historical evidence to deliver a clear assessment and monitoring plan.
Water quality monitoring
Assess observable indicators such as chlorophyll-a, suspended matter, water clarity, surface temperature, and cyanobacterial risk. I interpret trends, data gaps, and limitations rather than presenting satellite measurements in isolation.
Extreme events and investigations
Examine suspected algal blooms, pollution events, drought, flooding, or unusual changes using current and historical observations. Findings help prioritise field sampling, follow-up work, and early warning thresholds.
Water extent, coasts, and operations
Map changes in water extent, shorelines, turbidity, and suspended matter to support reservoir management, coastal studies, infrastructure planning, and dredging oversight where satellite conditions are suitable.
Clients & Partners
Collaborating with organizations committed to protecting aquatic ecosystems and advancing sustainable water management.
Pirin National Park
It is one of the three national parks in the country, the others being Rila National Park and Central Balkan National Park. The park was established in 1962 and its territory was expanded several times since then. Pirin National Park was declared a UNESCO World Heritage Site in 1983.
WaterWarden partnered with "Pirin National Park" with researching and monitoring glacial lakes in the park.
Bulgarian Biodiversity Foundation
BBF has been working to conserve biodiversity in Bulgaria and neighboring countries, supports the participation of citizens and local communities. WaterWarden has partnered with reports about the effects of mining industry on aquatic ecosystems

Black Sea NGO Network
Black Sea NGO Network (BSNN) came into existence in 1998 as a result of the development of the NGO community in the countries surrounding the Black Sea. Its predecessor was the International Black Sea NGO Forum. The first regional meeting of the network was held in Varna in September 1998. We have partnered with BSNN on multiple occasions regarding Black Sea conservations events and lectures where we had the opportunity to present us and our mission.

East Aegean River Basin Directorate
The East Aegean River Basin Directorate is a regional water management authority in Bulgaria with its headquarters located in Plovdiv. It operates under the Ministry of Environment and Water to manage river catchments, protect water resources, and implement environmental standards. They were crucial partners in validating our data and field testing our platform.

Summer 2026: WaterWarden’s beach water condition rankings
WaterWarden’s summer 2026 review compares water conditions at 24 monitored beaches and coastal areas. It also highlights what I see as a failure of institutional responsibility: despite my repeated warnings before incidents occurred, I have not seen an adequate response from the organisations responsible. These institutions must explain their inaction, investigate the concerns raised, and fulfil their duty to protect the waters we depend on for drinking, recreation, and the places where our children swim and play.

WaterWarden Reaches the Top 10 at Startup World Cup 2026 Varna
We're excited to share some incredible news WaterWarden was selected as one of the Top 10 startups in Bulgaria to compete at the Startup World Cup 2026 Varna.
Water Warden Wins First Place & Best Innovation at Blue Heritage Innovators 2026
Water Warden took home First Place overall and the Best Innovation Award at the Blue Heritage Innovators 2026 bootcamp! Read how our zero-hardware satellite intelligence platform provides proactive early warnings for toxic algal blooms , and how municipalities, coastal resorts, and regional water utilities can partner with us to ensure water safety for the upcoming summer season
The case of a Varna Bay and its water quality
Large coastal cities frequently face challenges related to water quality, and Varna is no exception. Using the WaterWarden platform, we were able to detect clear signs of water contamination, including elevated chlorophyll and suspended matter levels. These indicators strongly suggest illegal sewage discharge into the sea - an issue made highly visible through the satellite-derived data and visualization tools provided by the platform.
Why does Algae and Chlorophyll matters?
Many natural and anthropogenic factors can drive the rapid development of Algae in the water body which can lead to many different issues in the ecosystems. Lets discover a quick overview of the Algae and Chlorophyll.
