Water Storage Changes of Lakes and Reservoirs Across Asia (2018–2023) and Their Effects in Flood Control

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Monitoring lake and reservoir water levels is critical for water resource management and flood risk mitigation. We integrate Sentinel‐3A/B and ICESat‐2 altimetry to reconstruct monthly water levels (2018–2023) for 7,433 lakes and reservoirs (>5 km2) across Asia and estimate their storage variations.

Distributed SE(d) Formation Control of Multi‐Agent Systems Using Relative Measurements

International Journal of Robust and Nonlinear Control, Volume 36, Issue 1, Page 100-116, 10 January 2026.
ABSTRACT This study develops a solution to the distributed SE(d) formation control problem of multi‐agent systems using only relative measurements between agents. In this problem, poses, that is, orientations and positions, of the agents are expected to achieve desired ones.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

Ecological Solutions and Evidence, Volume 7, Issue 1, January/March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...
