Natural engineered streams rarely share the same classification framework.
A new #GSABulletin study bridges that gap, identifying 12 stream types across the San Francisco Bay Area—advancing restoration & watershed planning in mixed landscapes.

At the Workshop on Restoring and Maintaining the Inter-Relationship of Surface Flow and Sub-Surface (Groundwater) Systems,” experts from leading research institutions and organisations shared scientific insights, case studies and policy perspectives on strengthening surface–groundwater connectivity for sustainable river basin management.
Prof. (Dr.) C. S. P. Ojha, IIT Roorkee, delivered a presentation on “The science of surface–groundwater interactions.”
The session focused on strengthening the scientific understanding of stream–aquifer dynamics, helping policymakers and practitioners better interpret how groundwater sustains river baseflows and how rivers recharge aquifers.

The 67th Executive Committee meeting of NMCG marked a major leap toward science-led river rejuvenation.
Chaired by DG Shri Rajeev Kumar Mital, the meeting saw participation from senior officials including Shri Gaurav Masaldan (JS & FA, DoWR), Shri Nalin Srivastava (DDG, NMCG), Shri Anup Kumar Srivastava (ED–Technical), Shri S.P. Vashisth (ED–Admin), Shri Brijendra Swaroop (ED–Projects), Shri Bhaskar Dasgupta (ED–Finance), Shri Prabhash Kumar (Project Director, UP SMCG), Ms. Nandini Ghosh (Project Director, WB SPMG), and other senior officers from NMCG and participating states.
The EC approved major scientific and infrastructure interventions to strengthen river management and pollution abatement across the Ganga Basin:
1. Research & River Science
- Monitoring of key Himalayan Ganga headstream glaciers
- Study on glacier melt–runoff changes in the Upper Ganga Basin
- 1,100 km SONAR bathymetric survey from Bijnor to Ballia to support sediment and flow modelling
- Digital Twin & Water Cycle Atlas for real-time, AI-enabled river basin management
- Managed Aquifer Recharge along paleochannels in the Ganga–Yamuna Doab
- Digitization and geospatial database of historic Ganga basin maps (pre-1900 to 1950 )

A decade after Tropical Storm Irene, New England's hillslopes are still eroding, feeding sediment into rivers and delaying recovery. Learn how this persistent erosion extends flood impacts in the #GSABulletin: doi.org/10.1130/B36139.1 #Geomorphology #Flooding #RiverScience
ALT A conceptual diagram for the post-disturbance recovery of connected watershed components informed by post-Tropical Storm Irene observations and recent models that incorporate hillslopes and connectivity into a broader framework for post-disturbance recovery in watersheds. The figure is intended to convey the authors’ conclusions that time scales of adjustment and recovery are likely dependent on extrinsic factors, such as imposed hydrology, sediment grain size and amount, and topography, as well as contingent on prior recovery or non-recovery of other watershed components.

Why Are Different Sediment Sizes in Rivers So Important? 🪨
From tiny clay particles to chunky cobbles, rivers carry a mix of sediment sizes, and that’s a very good thing!
Diverse sediment = a healthy river!

🌊 Did you know that the elevation profiles of river deltas vary in fascinating ways?
A #GSABulletin paper explores this diversity through an analysis of 29 large deltas. The authors discovered that deltas confined by protective coastlines tend to develop significantly larger platforms. These deltaic platforms, separated from the fluvial fan by a distinct slope break, appear to accumulate more effectively when confinement prevents marine processes from eroding their fine-grained sediments. This finding has important implications for how we understand delta formation, land use, and hazards.

Modern river deltas show surprising elevation patterns—those with protective coastlines tend to build larger platforms.

Dr. M. Ravichandran, Secretary, Ministry of Earth Sciences, graced the National Symposium on River Science in India as the Chief Guest, underscoring the vital role of science and collaboration in conserving our river systems.
Organised jointly by IIT Kanpur and Delhi University on 11th August 2025 at the Indian National Science Academy, New Delhi, the event celebrated the outstanding contributions of Prof. S.K. Tandon a stalwart in Indian geology and river science on his 80th milestone year.
With thought-provoking sessions on river science, climate impacts, and human interventions, the symposium set the stage for a post-event action plan including a comprehensive policy note, research repository, and sustained collaboration for a sustainable river future.

Getting ready for some fish sampling on a beautiful sunny day.
The block net at the upstream end of the sampling reach prevents fish from escaping.
All fish of 4 different species, including river lampreys (!), were released back into the river.
