A peek into a USGS planning meeting to coordinate water-quality sampling efforts in response to Harvey. This sampling effort is part of the federal government’s broad efforts to ensure public health and to support the state, tribal, and local response to the storm
Sachin D Shah
Sachin is the Social and Economic Drivers Program manager for the USGS Water Mission Area and leads the USGS climate adaptation team tackling Ukraine's food insecurity. From 2021 to 2023, he was the Environmental Justice Science Advisor for the Dept of the Interior’s Office of Environmental Policy. In 2024, he served as a Policy Advisor at the White House Office of Science and Technology Policy.
Sachin has over 20 years of hydrology, policy, and international development experience with the U.S. Geological Survey, World Bank Water Program, Council of Energy-Environment-Water (CEEW), and the UN-Shell Water-Energy Nexus Initiative.
Sachin works at the intersection of hydrology, socioeconomics, and social justice to understand the human dimensions of water security and risk domestically, Mekong River Basin, South Asia, and Ukraine.
Science and Products
Socio-Hydrology
The Socio-Hydrology Team conducts interdisciplinary studies spanning socioeconomic, hydrologic and climate science. Applying qualitative and quantitative approaches, we help stakeholders identify and assess a suite of water and climate risks. Our methodology provides a means for resource managers, practitioners, and communities to analyze and evaluate risks, vulnerability, and resiliency to...
Texas Gulf Coast Groundwater and Land Subsidence Program
The Texas Gulf Coast Groundwater and Land Subsidence Program web application illustrates how groundwater, sediment compaction, and land-elevation change are related in the Houston-Galveston region in Texas. The new app was developed by the U.S. Geological Survey Oklahoma-Texas Water Science Center and is available at https://txpub.usgs.gov/houston_subsidence/.
Subsidence Science in Oklahoma and Texas - Overview
The USGS Oklahoma-Texas Water Science Center (OTWSC) has researched land-surface subsidence for more than 40 years. OTWSC collects and interprets groundwater level and aquifer sediment compaction data to understand the effects of groundwater withdrawal on land surface subsidence.
