The Importance of Dynamic Density Compensation in Water Level Monitoring
OBTAINING SUPERIOR WATER LEVEL ACCURACY IN COASTAL ENVIRONMENTS In-Situ Inc. water level instruments measure the sum of all pressures (atmospheric and hydrostatic) exerted on a pressure transducer and use that data to calculate water levels. Water density contributes to the total hydrostatic pressure. Saltwater has a higher specific gravity than fresh water. A standard column of saltwater exerts ...

Spatial and temporal distribution of snow water content and response to air temperature in seasonal snow in the western Tianshan Mountains, China
The snow water content was measured with a portable instrument (Snow Fork) in the Tianshan Station for Snow-cover and Avalanche, Chinese Academy of Sciences (TS) during the snow period in the winter of 2009–2010. The results indicated that the variation of snow water content increases exponentially over time. In the accumulation-stable period, the migration of liquid water is from the ...

Biomonitoring can measure what chemical monitoring cannot
Algae and Daphnia (waterfleas) forewarn drinking water sector Biomonitors, instruments which measure the biological effects of different substances on organisms, detect substances which cannot be detected using chemicals anaylsis methods. This is also valid for combinations of substances which are present in the water in large concentrations. A well-functioning monitor is necessary since our ...

Hwy 60 test, Lodi, Wisconsin
It’s hard to find Civil & Environmental Engineering Professors Craig Benson and Tuncer Edil behind their desks. You have a better chance of locating them on a construction site, actively participating in the task at hand. They prefer to teach through hands-on lessons, like those found in their groundbreaking soil stabilization research efforts. Benson and Edil are currently involved in two ...

UW team sending autonomous surfboard to explore Antarctic waters
This week, a surfboard arrived in Antarctica. Not only was it missing a surfer, but the unique board was covered in parts that let it move independently and measure the surrounding seawater. The University of Washington project will first use the Wave Glider to investigate the summer conditions near Palmer Station on the Antarctic Peninsula, to better understand how the warming ocean interacts ...

Antifouling System Reduces Algal and Biological Growth on the In-Situ TROLL 9500 Water Quality Instrument
Abstract New regulations regarding clean water have increased the need for long-term environmental monitoring. As water quality sensor technology improves and becomes more stable, the limiting factor in these projects becomes biological and non-biological fouling of instrumentation. Biofouling of environmental equipment increases site visits and maintenance, which elevate monitoring costs. In ...

Multilevel Systems
Untitled Document Introduction A multilevel system is a groundwater monitoring device which allows the monitoring of a number of discrete groundwater zones within the subsurface. The system consists of packers and ports which are placed at varying locations along a casing string, effectively isolating and providing access to, each monitoring interval, see Figure 1. Due to ...
