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.
