Plastic pollution in rivers is a growing global crisis, with rivers like the Ganges, Yangtze, and Buriganga transporting millions of tons of waste annually into oceans. Factors such as rapid urbanization, poor waste management, and single-use plastics drive this issue, endangering ecosystems and human health.

In our latest Performance Report, we assess the effectiveness of BWI’s discharge forecast model for the Gardon River, specifically at the Pont de Russan outlet. Covering an area of 1,533.7 km², this catchment, located northwest of Nîmes, in southern France, features 362 reaches and 4 dams. The region typically experiences dry conditions with low baseflow (2-5 m³/s) but is vulnerable to sudden heavy rainfall and flash flooding. The model demonstrates strong overall performance (NNSE 0.81), accurately simulating baseflow, flood detection, and flood recession. This performance is crucial for managing water resources, supporting early warning systems, and aiding the design of critical flood prevention infrastructure.

River discharge forecasting is a cutting-edge tool for flood prevention, providing early warnings to protect lives and minimize economic losses. Advances in hydrological models have proven crucial in flood-prone regions like France, India, Bangladesh, and Senegal.

NASA’s GRACE satellites measure changes in Earth’s gravity field to track groundwater depletion, aquifer dynamics, and river discharge. By monitoring large-scale water storage shifts, GRACE provides crucial data for water management and predicting climate-related impacts like floods and droughts.

This visit marks a significant milestone in our ongoing mission to enhance water resource management through cutting-edge technology, further establishing BWI as a trusted technology partner to governments committed to sustainable development.Sri Lanka, with its rich hydrological landscape, faces unique challenges such as seasonal flooding, droughts, and water quality issues. During his visit, Jeremy is engaging with officials to showcase how BWI’s solutions can provide real-time data for proactive water management, flood risk assessment, and environmental conservation.

This article explores the various methods hydrologists use to study the water cycle, emphasizing their importance in ensuring sustainable water management and mitigating natural disasters.

Climate change, human activities, and subsurface processes further add to these complexities. Advancing technology and interdisciplinary research are essential to overcoming these challenges in hydrological science.
