A Fuzzy‐Logic and Machine Learning‐Based Framework for Water Quality Index Classification in Extensive and Intensive Aquaculture Systems

Engineering Reports, Volume 8, Issue 6, June 2026.
This study presents an Internet of Things (IoT)‐to‐Cloud framework for real‐time monitoring and prediction of the Water Quality Index (WQI) across both extensive and intensive aquaculture systems. By integrating Fuzzy Logic biological thresholds with ML classification, the Random Forest model achieves over 99.5% accuracy in both environments ...

New terrace‐tile inlet technologies reduce sediment and nutrient losses

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Surface inlets such as Hickenbottom risers (HBRs) are often used to drain closed depressions and potholes across agricultural landscapes in the US Midwest. Although HBRs provide efficient drainage, they also transport substantial nutrient and sediment losses from fields.

Applying a Multisector Scenario Framework to Evaluate Past and Future Public Surface Water Supply Infrastructure Strategies in Texas

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Facilitating decisions over future infrastructure transitions benefits from understanding past strategies to inform future scenario development. Here, we apply a scenario‐based indicator framework to generate plausible, spatially explicit future Public Water Supply Infrastructure (PWSI) alternatives.

Size‐based regulation and water quality: Evidence from the Iowa hog industry

American Journal of Agricultural Economics, Volume 108, Issue 3, Page 829-855, May 2026.
Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, Volume 75, Issue 2, Page 815-839, April 2026.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.
