Measuring Change

Measuring Change:

Justin and Bobby Installing PVC Staff Gages and Measuring Stream Discharge

The natural environment is constantly changing. The earth pays no mind to the planning and infrastructure in which we’ve invested our time and resources. In the case of streams and rivers, change is inevitable. It is a stream’s nature to move and shift its course gradually over time. Sometimes, these changes happen violently overnight, while others occur slowly, but continually. When these changes occur, they become extremely costly to projects that rely on a dependable water supply.

For these projects’ sponsors, planning and resource management are essential to minimize costs associated with the changes, to ensure that all regulatory requirements are met, and to protect the waterway itself. As changes continue in the stream we need to adjust our understanding of the environment to better equip ourselves for the unpredictable nature of, well, nature.

One of the ways that GeoServices Ltd. helps to create better water resource management plans for our clients is with the accurate measurement of surface water supply sources. The task that is being performed in the above photos is a technique used to measure the stream discharge, or the volume of water moving down a stream per unit of time. By using a combination of time tested procedures and modern technology, GeoServices can measure and monitor the discharge over a wide range of wet and dry conditions. This information can be used to predict the volume of water that can safely be withdrawn at any given time. When we finish, our client receives the tools to monitor their available resources in-house, allowing them the ability to adjust usage if need be.

With our knowledgeable and experienced staff, GeoServices Ltd. works hard to provide efficient, cost effective options for your projects. Combined with our close relationship with regulatory agency personnel at both the state and federal level, we’ll not only help you get the job done, but also navigate the regulatory hurdles.
