  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Sewer Level Monitoring - Photos

    Sewer Level Monitoring - Photos Photos in this article present the complexity and versatility of sewer level monitoring. When examining the photos, pay special attention to the stand-alone autonomous characteristics of each installation. In lack of any cabling from the outside, whether data cables or power cables, the solution is fed from its own battery power supply. Data is tranmitted ...

  • Regional Ground Water Level Monitoring in Germany

    Reference Project: Regional Ground Water Level Monitoring, Germany ribeka is responsible for monitoring the ground water levels within an area of over 4.000 km2 in the western German province of North Rhine-Westphalia. Within this densely populated area that comprises many large cities (e.g. Cologne and Bonn) as well as Europe’s biggest brown coal open mining site, extensive ground water ...

  • Water Level Monitoring and Control Solutions for the UK Internal Drainage Boards

    Pulsar Process Measurement have been involved in design, manufacture and supply of non-contacting Ultrasonic Level and Pump Control systems for the Internal Drainage Board industry for many years. Three typical examples of the application of this equipment are installed at North Level IDB Cross Guns Pumping Station. The original Cross Guns Pumping Station was built in 1938 to house three 760mm ...

  • 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 ...

  • Monitoring Metal Contamination in Water

    Metal contamination in drinking and source water has proven to have economic and health impacts on the human race. Regulatory agencies understand the importance of remediating metal contamination in our water supply to ensure safe consumption of drinking water. In order to properly remediate our water supplies, one must first determine cause of contamination and the source of the problem. ...

  • Monitoring of water node in wroclaw

    Background Wroclaw's water node has complicated structure. The river Odra has 3 main riverbeds and a lot of channels which are located in the centre of town. There are almost 100 hydro buildings which control flow of the water through the city and protect it against theflood. The great flood in 1997 proved that no one has control over it. Communication systems failure caused ...

  • Tidal influences on unconfined water levels in wells.

    Tidal effects have the potential to measurably affect water level measurements and the estimation of groundwater flow direction and gradient. This has significant implications for the prediction and monitoring of contaminant plumes in coastal areas. Studies were conducted at two near-coastal sites in San Diego County, California, to evaluate the impact of tidal variability on the interpretation ...

  • Ultrasonic depth sensor to measure water levels

    The Dutch algae control company LG Sonic introduced an ultrasonic depth sensor to give the customers real-time insight in the water levels which allows them to adequately deal with water level fluctuations. Reservoirs used for industrial processes or the production of drinking water often deal with strong water level fluctuations. Due to events of high demand and evaporation, water levels in ...

  • 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 ...

  • Assessment of riverside groundwater flood risk induced by high river water levels using a numerical model and monitoring data

    Large barrages have been constructed on the main rivers in South Korea to store water and mitigate fluvial flooding damage. However, the increase in water levels behind the barrages can potentially lead to a rise in groundwater levels in the riversides. The purpose of this study was to describe the effect of a barrage on groundwater levels and to test the applicability of a numerical model to ...
