Measuring water quantity and quality in surface water (open channels, rivers, reservoirs, lakes, and estuaries) is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first water current meters were designed in 1875.
Surface water monitoring as an application covers many different environments and can require different equipment depending on the monitoring requirements. Possible environments include lakes, rivers and coastal waters where the monitoring may be focused on water quality or water level measurement. Aquaread offer instruments suitable for each of these environments and have a wide range of possibilities depending on the kind of data you wish to collect.
The Sorbisense method is especially suitable for measurements in dynamic environments. For example, in rivers, streams and lakes.
The method is innovative and allows you to implement continuous and cost effective measurements in both urban and in rural areas. For example, measuring the leaching of nutrients from the cultivation of wetlands and measuring water quality in rainwater and sewage.
Easily and accurately assess the physical, chemical, and biological characteristics of any aquatic system. From spot sampling to long-term remote monitoring, In-Situ has the right equipment for your surface water quality monitoring project.
Pollution Risk: Surface water encompasses storm water derived from hard standing areas, river water and reservoirs. All types of surface water are at risk from ingress of pollution and therefore need to be monitored. On-line continuous monitoring can identify and alarm pollution so corrective action can be taken
Aquaread stock a wide range of testing equipment designed to track a number of parameters and water quality testing measures. These can be used in many different bodies of water, including rivers, lakes, streams and seawater. The advantages of tracking water quality and testing for numerous parameters means that it is easier to notice changes which could cause damage to aquatic ecosystems. Early detection not only helps with monitoring water quality, but also helps to put mitigating measures in place. We have a...
Water monitoring involves many different activitites, from ensuring the quality of surface or underground water, both for human beings and animal life, to the monitoring of a country’s water infrastructure. Wireless sensor networks are becoming increasingly popular in this area and ADVANTICSYS has already explored its use for many novel applications.
STS has been a hydrologist partner for many years, and through this work we have developed the experience to become specialists in the monitoring of river, lake and ground water levels. Measuring groundwater level is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water.
Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.
Problem: A challenging aspect of drinking water treatment is often predicting or monitoring the changes that occur with incoming water quality. Seasonality, weather events, agricultural practices or upstream discharges can influence the quality of both ground and surface water over time. With multiple variables impacting source waters, monitoring historical trends may not be sufficient to predict raw water changes or detect uncharacteristic events.
Based on the wireless radar technology SenZ2 provides a complete solution for remote, real-time monitoring and logging of water levels. For the water sector real-time insights in water levels is key. Accurate level-measurement data can result in improved policy, reduction of risks and direct cost savings. The Wireless Level Radar (WLR05-2G/001) can monitor waste water and overflow, surface water and groundwater in remote places without any power source. With radar as the most reliable and cost-effective level...
The EU Water Framework Directive (2000/60/EC WFD) is probably the most significant international legislative instrument in the water field. Water management policy as set out in the WFD is focused on surface water as it flows through river basins to the sea. An integrated approach has been introduced for matters concerning water quality and water quantity and the Directive establishes a framework for water management based on river basin districts. Linked to the WFD objectives, a series of milestones has to be...
In many industrial or professional applications where water is being stored, biofilm may grow. The growth of biofilm can damage the installations and reduce efficiency of the circuit. A biofilm can grow certain substrates which can be found in water. When temperatures are high, for example in cooling towers, a matrix of different micro- organisms such as bacteria, fungi, algae can grow very rapidly causing the formation of a biofilm on certain surfaces submerge in water. During the formation of this biofilm,...
Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.
With Sound Velocity through the water being of prime importance during seismic surveys, Valeport offer a variety of sensors and probes to measure sound velocity with an unsurpassed accuracy level. Whether you require just a sensor or a SVP for profiling, we have products for surface use and up to 6000m depth operation.
Level detection is a very widespread measurement requirement. Whilst there are many techniques for detecting liquid surfaces, it is much more challenging to identify the interface between liquids and other systems.
GPR exploration of fresh water reservoirs allows user to examine in details the bottom.
The important feature of GPR use that is to be mentioned - it can examine the structure of the bottom. I.e. there is possible to find underwater items located inside the bottom stratum.
Also GPR can provide an information about the thickness of bottom silt or bottom ground, and its volume structure.
The same exploration is very problematic if made by other means.
In the summer 2012 VIY3-300 GPR was examined as sub-bottom...
