  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Water Level Monitoring Using a Druck Depth/Level Sensor

    In this Tech Article from CAS DataLoggers and dataTaker, we describe the process of connecting the Druck PTX 1830 depth/level sensor to a dataTaker DT8x series data logger. These two components can function as a water level monitoring logger and record depth measurements. The Druck sensor outputs a 4-20mA ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...

  • Lake water levels for calibration of the S-HYPE model

    Lake water levels are easy to measure, and can be seen as a transformation of discharge. Water level measurements from 42 lakes in Sweden were analysed, and eight of these lakes were modelled using the Swedish S-HYPE model. The objective was to test if a hydrological model can be calibrated using water level data instead of discharge. A semi-analytical lake routing was developed to resolve ...

  • 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 ...

  • Warmest Decade on Record Brings Record Temperatures and Weather Extremes

    In recent years weather events have whiplashed between the extremes of heat and cold, flooding and drought. Carbon dioxide and other greenhouse gases—largely from the burning of coal, oil, and natural gas—have loaded up in the atmosphere, heating the planet and pushing humanity onto a climatic seesaw of weather irregularities. High-temperature records in many places are already being ...

  • Example of water level data logger use - case study

    Geo Kamp Limited is pleased to present a typical hydrogeologic project using Heron Water Level Data Loggers (referred to as the dipperLog). The accompanying hydrographs represent the data collected for a Test Well located near Lake Simcoe (north of Toronto) in 2010. It was difficult to coordinate the schedule of the water well contractor due to inclement weather (bitterly cold) and the project ...

  • Analysis of Organophosphorus and Organonitrogen herbicides in water using GC/MS with selected ion recording

    Laboratories monitoring trace level pesticides and herbicides by gas chromatography/mass spectrometry (GC/MS) frequently utilize Selected Ion Recording (SIR) techniques to maximize analytical sensitivity for quantification. With analytical standards, precision is limited to a large extent only by the autosampler and other instrumental effects. However, real-world samples pose a greater challenge. ...

  • Contaminated Water

    Treatment of Contaminated Mine Water Discharge Recent estimates have suggested that in the UK 2,500 km of streams and an area of 9,000 km2 of groundwater bodies are at risk of failure of Water Framework Directive Objectives due to mine water pollution (Jarvis & Rees 2004). For over two decades the Loughor Estuary in South Wales, which carries SSSI status, had been ...

  • 2012, a year of record-breaking extreme weather and climate

    The United States experienced its hottest year on record in 2012. On a global scale, not only did last year mark the 36th consecutive year the annual global temperature was above average, but each successive decade in the last 50 years has been the warmest on record. Additionally, the recent draft National Climate Assessment states that it is “virtually certain” that global ...

  • Eco-economy indicator: past decade the hottest on record

    The first decade of the twenty-first century was the hottest since recordkeeping began in 1880. With an average global temperature of 14.52 degrees Celsius (58.1 degrees Fahrenheit), this decade was 0.2 degrees Celsius (0.36 degrees Fahrenheit) warmer than any previous decade. The year 2005 was the hottest on record, while 2007 and 2009 tied for second hottest. In fact, 9 of the 10 warmest years ...

  • A Record Year for EHS Non-Compliance fines in the UK

    The sentencing landscape for Environmental, Health and Safety offences in the UK (England & Wales specifically) has undergone significant change over the last 18 months. In England and Wales, companies have been handed record fines in these fields. So what does this mean for businesses? ...

  • The joint effect of water price changes and pressure management, at the economic annual real losses level, on the system input volume of a water distribution system

    This study attempts to examine the factors affecting the residential water demand level in the city of Kozani in Greece. Based on an 8-year (2005–12) detailed sample of residential water demand panel data, the values of the water price (WP) elasticity of residential demand are identified, and the influence of socio-economic and demographic factors and climate conditions on water-use levels and ...

  • A Brief History of Stevens` 116 Year Chart Recorder Legacy

    The legendary mechanical chart recorder for environmental monitoring dates back to 1911, when John C. Stevens invented the Type A chart recorder. In 1906, J.C. Stevens was the Hydrographer for the USGS out of Portland, Oregon, and was soon promoted to District Engineer.  While with the USGS, he realized that hiring local citizens to observe and record height of water was not accurate or ...

  • Stevens Equipment Records Historical Information During Tsunami - Case study

  • OTT Hydromet sensors for measuring water level in creeks and bayous, played a critical role during Hurricane Harvey

    Hurricane Harvey, and the subsequent flooding, was an unprecedented and devastating event in eastern Texas. Harvey produced an average of 33.7 inches of rainfall over the 1,777 square miles of Harris County over a 4 day period which equates to 1 trillion gallons of water and is also 68% of the yearly annual rainfall. Of the 22 watersheds across Harris County, 13 established new record water ...
