New paper optimizes testing of groundwater for vulnerability

Using the DRASTIC method, an index-based methodology, researchers assessed groundwater contamination to develop a vulnerability map.

How wet is your wetland?

The U.S. Army Corps of Engineers and the Swamp School have each released tools that automate the process to determine if a wetland is in dry, normal, or wet condition at any time.

Using remote sensing to detect changes in soil surface elevation

Agriculture tillage is the process of ripping the soil to prepare it for planting. This is the most common management method in U.S. agriculture. Remote sensing contributes to the monitoring of topographical and land morphological changes. A new paper in the Journal of Surveying Engineering, "Comparison of sUAS Photogrammetry and TLS for Detecting Changes in Soil Surface Elevations Following Deep Tillage," assesses the effectiveness...

New paper predicts transient response of air pockets in pipe networks

A paper in the "Journal of Hydraulic Engineering" explores how air pocket anomalies may distort transient signals.
