This study uses high resolution hydro-meteorological measurements to model the moisture retention dynamics in a subsurface soil column in response to rainfall events. We report in-situ measurement of soil moisture at 10–40 cm soil depth (each 10 cm) and corresponding meteorological parameters (rainfall, relative humidity, evaporation, etc.) at every 10 minute interval. We have used these measurements to develop an automated machine learning based model and assess its prediction capabilities.

This study examines the Gangotri Glacier’s ice dynamics and ice thinning patterns over time, highlighting its rapid mass loss and the influence of climate change. By analyzing ice movement and thickness change, we found significant glacier shrinkage, particularly in the upper regions of the glacier main trunk. The findings emphasize the need for continuous monitoring to better predict future changes.

Short summary
The occurrence of frequent floods in recent years due to changing weather, heavy rainfall, and the natural landscape, has caused major damage to lives and property. This study looks at flood risks in the Ganga Basin, focusing on the factors that cause floods, the areas affected, and the vulnerability of people. The study uses NASA's night-time lights to track human activities. This helps to show how risks are connected to expanding human activities, and changing resilience to floods.

Short summary
Soil moisture and groundwater play a significant role in the hydrology of the critical zone in the Earth system, specifically in an agriculture-driven environment. We present here the space-time dynamics of both these components from a well-instrumented critical zone observatory in the Ganga basin, India. Influences on the spatiotemporal variability along with the optimal sampling strategies are explored in this study, providing an insight to the stakeholders for efficient water management.

Short summary
This study demonstrates an innovative methodology to estimate the formative discharge of alluvial rivers from remote sensing images. We have developed an automated algorithm in Python 3 to extract the width of a river channel from satellite images. Finally, this channel width is translated into discharge using a semi-empirical regime equation developed from field measurements and threshold channel theory that explains the first-order geometry of alluvial channels.
This study demonstrates an innovative methodology to estimate the formative discharge of...
