Soil Water Content Monitoring Using Electromagnetic Induction
The use of electromagnetic ~EM! induction measurements was evaluated to predict water content in the upper 1.50 m of a prototype engineered barrier soil profile designed for waste containment. Water content was monitored with a neutron probe, and bulk soil electrical conductivity was monitored with a Geonics EM38 ground conductivity meter at ten locations at approximately monthly intervals over...
متن کاملBenchmarking countries' environmental performance
Environmental performance assessments are often conducted using environmental indicators. Although these indicators provide a starting point for performance assessments, they do not provide guidelines that countries should follow to improve performance. This paper develops an enhanced Data Envelopment Analysis (DEA) model that provides a single summary measure of countries’ environmental perfor...
متن کاملThe microelectronic wireless nitrate sensor network for environmental water monitoring.
Quantitative monitoring of water conditions in a field is a critical ability for environmental science studies. We report the design, fabrication and testing of a low cost, miniaturized and sensitive electrochemical based nitrate sensor for quantitative determination of nitrate concentrations in water samples. We have presented detailed analysis for the nitrate detection results using the minia...
متن کاملSquirtle: An ASV for Inland Water Environmental Monitoring
This paper presents the Squirtle, an Autonomous Surface Vehicle (ASV) for autonomous navigation and capable of manoeuvring in tight river environments. Its main features include precise localization with RTKGPS and inertial sensors, high manoeuvrability and autonomy, depth sensing and obstacle detection. Its purpose is the exploration and mapping of the bottom of rivers and of their shores. The...
متن کاملBenchmarking a Soil Moisture Data Assimilation System for Agricultural Drought Monitoring
Agricultural drought is defined as a shortage of moisture in the root zone of plants. Recently available satellite-based remote sensing data have accelerated development of drought early warning system by providing continuous soil moisture information in space and time. Nonetheless, the shallow sensing depth (top few cm) and uncertain accuracy of currentlyavailable satellite soil moisture retri...
