Large scale groundwater withdrawal and its consequences on the closing of the upper Musi basin in India
The Musi basin is a sub-basin of the river Krishna in India. Data on ground water levels for 20 years (1985?2004) including the data of Digital Water Level Recorders (DWLR) is analysed to investigate the large scale ground water withdrawal and its affects on reducing the inflows reaching the downstream reservoirs in the basin. The investigations have revealed that the deeper the pre-monsoon ...

Monitoring watershed health
Background Municipal water quality managers recognize the need for data that can be used to monitor and assess the impact of urbanization on the condition of natural watersheds. Storm events, in conjunction with the alteration of native landscape, building of roads and overuse of fertilizer, can contribute to excess nutrients, sediment and other pollutants in environmentally significant ...

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 ...

Get Custom THM Stripping Without Breaking the Bank
To limit costs, consider site-specific parameters if installing off-the-shelf trihalomethane removal systems. DISINFECTION by-product (DBP) regulatory compliance requires public water systems to achieve total trihalomethane (TTHM) levels of 80 ug/L (ppb) or less for a locational running annual average throughout a community. Often a water treatment plant's most cost-effective approach is to ...

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 signal and can be powered by the dataTaker’s switchable 12V regulated voltage output. ...

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 ...

Alert Labs Partners with Basement Waterproofing Experts to Minimize Water Damage
In a perfect world, the risk of a basement flood would fall to zero for every property owner who had a sump pump. The reality is that many people just don’t know if their sump pump will protect them from water damage during the next spring thaw or heavy rainfall. Enter the world’s first predictive sump pump sensor, Sumpie. Designed and manufactured by Alert Labs, Sumpie monitors and ...

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 ...

Fold geometry model of Coyote hills segment of Puente hills blind-thrust system applied to interpretation of long-term water level data
Recent work by others along the Coyote Hills segment of the Puente Hills blind-thrust system has imaged the near-surface structural features generated by activity of that intrabasin fault. Published shallow seismic profiles near the south flank of the Coyote Hills indicate the blindthrust system is expressed by south-facing folding of Quaternary terrestrial sediments underlying the hills. ...

4 Cities Show Leadership in Adapting to Local Climate Impacts
Extreme rainfall hammered Boulder, CO with more than 17 inches of precipitation in just six days earlier this year. Salt Lake City’s snowpack—a critical water source—is showing troubling changes in its melting rates. Costly floods and overflowing storm drains plague South Florida’s coastal cities, such as Pinecrest. And storm surge and flooding from Hurricane Sandy caused ...
