Abstract The fate of the terrestrial biosphere is highly uncertain given recent and projected changes in climate. This especially acute for impacts associated with drought frequency intensity on distribution timing water availability. development effective adaptation strategies these emerging threats to food security are compromised by limitations our understanding how natural managed ecosystems responding changing hydrological climatological regimes. information gap exacerbated insufficient...
The role of macropores in soil and water processes has motivated many researchers to describe their sizes shapes. Several approaches have been developed characterize macroporosity, such as the use tension infiltrometers, breakthrough curve techniques, image‐analysis sections soils, CAT scanning. Until now, efforts quantitative terms concentrated on two‐dimensional (2‐D) geometry. objective this study is nondestructively quantify three‐dimensional (3‐D) properties four large undisturbed...
Abstract Multi‐region modeling can be used to simulate dynamics of preferential flow in soils. However, the criteria determine boundaries between regions have been defined arbitrarily up now. Therefore, there is a need develop reliable technique isolate and characterize domains soil. The primary objective this study was method for isolating characterizing large undisturbed soil column using computer assisted tomography (CAT) scanner. This approach allows real‐time examination mechanisms...
Abstract This research investigates ecological responses to drought by developing a conceptual framework of vegetation response and investigating how multiple measures can improve regional monitoring. We apply this approach case study recent in Guanacaste, Costa Rica. First, we assess severity with the Standard Precipitation Index ( SPI ) based on 64‐yr precipitation record derived from combination Global Climatology Center data satellite observations Tropical Rainfall Measuring Mission...
Single photon emission computed tomography (SPECT) is an imaging technique that widely used in medical diagnosis. This has never been applied to soils. The objective of this study was investigate the capabilities SPECT scanning for visualizing preferential flow soil. paper describes principle and its application tracer breakthroughs four large undisturbed soil columns (800‐mm length × 77‐mm diam.). new approach allows real‐time analysis patterns radioactive tracers 2‐D using planar imaging,...

The evolution of European legislation has led to the rehabilitation many wastewater treatment plants, sometimes through installation a biological complementary stage. Among these sites, some plants in mountain areas are considering biofiltration process. design such especially for winter, appears be tricky because very low influent temperature, high performance requested ammonia removal and important short term variations loads. monitoring site during two consecutive winters allowed us study...
