Xylem Water Solutions were appointed by Local Government in Bundaberg to establish hydrographic monitoring site in Bundaberg Creek, just upstream of the confluence with the Burnett River. The monitoring objectives at the hydrographic monitoring site consisted of surface water level and flow measurement in real-time available through cloud based hydrological information management system (HIMS). Part of the initial site establishment consisted of performing detailed bathymetric survey of the Bundaberg Creek from upstream the Quay St Footbridge up to the confluence of the Burnett River for hydraulic analysis of the channel.
Previously, volume surveys of impounded waters in pit lakes had been undertaken using Total Station positioning and soundings taken froma boat on the lake. This was a labour intensive process with up to four people required for the survey. In addition to this was the safety concerns associated with working on the water in boats. Kellie Carter, Senior Environmental Advisor, approached Xylem regarding any possible solutions to make this process more efficient.
In 2015, a UCLA team of research scientists returned to southwestern Greenland to study meltwater runoff over three solid days of uninterrupted monitoring. If the their 2012 expedition provided snapshots of the movement of meltwater, the follow-up study that measured the same stream hourly for seven days straight delivered a movie of supraglacial stream flow-data proportions.
With the large volume of cargo vessels relying on the country’s ports, the Maritime and Port Authority of Singapore (MPA) has the challenging task of managing the safe and efficient operation of surrounding waterways. While the average consumer may not spend much time considering how goods arrive at their doorstep, behind the scenes agencies like the MPA are intimately involved with the logistics.
In 2011 a series of gauging stations was established along the Johor River which measured river water level and velocity to gain a better understanding of the existing river flows. The Johor River is an important source of water for several water treatment plants. However during high tides and in dry seasons, a salt water wedge pushes upstream affecting water quality and thus water supply.
Water management in the Sinar Mas Forestry plantations presents an immense amount of challenges. With over 2.6 million hectares of concession areas to manage, a comprehensive and dynamic water management plan is essential. For example, during the annual dry season, water table management is critical to prevent peat fires and for peatland forest conservation. However during the wet season, attention is switched to flood management at low elevation areas.
It was a small lake, but a big challenge. Covering about 43 acres (17 ha), the lake is at the center of the Lake Forest subdivision in Daphne, Alabama and is completely surrounded by private property. Bret Webb, associate professor of Civil, Coastal and Environmental Engineering at the University of South Alabama, was starting a month-long study of sedimentation in the lake to help authorities evaluate flood storage capacity and potential restoration activities, but he was having trouble reaching the water. There was no public boat access, and thick vegetation prevented surveying elevations above the water level.
The Linggiu Reservoir in Johor State, Malaysia, plays a critical role in regulating and releasing waters to the Johor River in order to “push” back a salt wedge in the downstream estuary where the main water works intake is situated.
Piloting a 256-meter (839-foot) cargo vessel into port is always a delicate operation, and it doesn’t get any easier with swift currents and stiff winds cutting across the narrow channel. Or fog. Or driving rain.
Silver Springs—a network of two dozen or more springs in central Florida—bubble up through central Florida’s Karst formations, limestone beds that have been carved by acidic groundwater and rain into baroque networks of caves, channels, domes and tunnels. Channels in the matrix flow with underground rivers and provide quick conduits between surface water and shallow groundwater. As domes collapse and sinkholes form, ancient paths are rerouted beneath the surface.
