Spring runoff: What is it and why does it matter?

When the weather gets warmer, snow in the mountains begins to melt. This is called spring runoff, and it’s crucial that researchers measure and understand it.

“Spring runoff is that big push of water that we get from snowmelt across the state,” says Dr. Ginger Paige, a professor in the department of Ecosystem Science and Management. What WyCEHG is trying to do is get better numbers on predicting the amount of spring runoff that may occur, by measuring snow water equivalent.”

The information that WyCEHG and other researchers collect is an essential resource to people across the state of Wyoming.

“We need that information for watershed planning, for allocation of water in our basins,” says Dr. Paige. “It’s also important in terms of potential flooding. All of the emergency management offices across the state are looking at this information for mitigating flood damages. The information is also valuable for agriculture, for farmers and ranchers and irrigators who need to know how much water is available.”

All of the information collected by researchers is available to anyone who is interested. The National Resources Conservation Service SNOTEL (short for Snow Telemetry) website shows information about snow water equivalents and spring runoff all across the state of Wyoming. You can also find hydrologic information for Wyoming at the NOAA hydrology website.

CI-WATER Project Insights: ADHydro

When it comes to water management, knowing how water moves and where it ends up is crucial. That’s why a team of CI-WATER researchers are working on a new model, called ADHydro.

ADHydro will be the most robust model of its kind, presenting high-resolution detail for a broad geographical area. It will enable researchers to more accurately measure how fast water soaks through the soil, how fast the water flows over land and more. With these calculations, researchers can determine where the water goes and how it gets there.

“ADHydro is physics-based, meaning that it simulates specific physical processes as opposed to a curve-fitting model that can be calibrated to match historical data, but doesn’t simulate specific physics processes,” says Dr. Robert Steinke, a software engineer on the interdisciplinary team developing the model.

“It’s important to CI-WATER because one of the goals of CI-WATER is to allow watershed managers in the field access to high performance computing resources,” says Robert.

The ADHydro model is set for initial deployment next year. The completed model will give researchers the tools they need to study water movement in the field, ultimately helping water managers better understand this essential resource.
