Legendary fluvial geomorphologist Reds Wolman once said “Floods come from too much water,” and that’s the phenomenon distilled to its core essence. But this bit of wisdom doesn’t give us much to go on if we want to understand what creates floods or why some areas are more flood-prone than …
In the previous post, I reviewed approaches for point measurements of precipitation (i.e., rain gauges), talked about the care that must be taken to site well and minimize undercatch, and identified some of the common data sources for rain gauge measurements in the United States. Rain gauges do a great …
As watershed hydrologists, we care a lot about precipitation, especially when it reaches the land surface (or the vegetation just above it). Precipitation is the dominant input to our water balances and a major driver of streamflow and water table responses. Because precipitation is so important, we need to spend …

From a distance, Anne has been watching an incredibly unusual summer play out in the Pacific Northwest, following a winter with far less snow (but more rain) than usual. Folks on the ground in Oregon have been collecting data on the response of the Oregon Cascades streams to “no snow, …
The Watershed Hydrology lab will be out in force for the Geological Society of America annual meeting in Vancouver in October. Over the next few days, we’ll be sharing the abstracts of the work we are presenting there. SENSITIVITY OF PRECIPITATION ISOTOPE METEORIC WATER LINES AND SEASONAL SIGNALS TO SAMPLING …
Congratulations to Darren Reilly who did a wonderful job defending his MS thesis on Tuesday. Darren’s thesis focused on the identification of groundwater pollution and its sources in rural northeastern Pennsylvania residential water wells. Darren will be preparing his thesis for publication in a journal and is looking for a …
This work is being conducted by undergraduate lab member, Allison Reynolds. Allison presented her work as part of the CUAHSI/USGS Virtual Workshop on applications of laser specs to hydrology and biogeochemistry. From that workshop, she will have an extended abstract published in a USGS open file report, and her poster …
Radar is increasingly used to measure precipitation in hydrologic science applications. It’s handy because it can be both frequent and areally distributed. This NWS newsletter does a great job of going over the basics of how weather radar can be used to derive rainfall rates and totals. This page gives a …
Cross-posted at Highly Allochthonous If you live in the eastern 1/3 of the US and you haven’t started paying attention to Hurricane Sandy, today is THE day. This odd late-season storm is going to hit the northeastern and mid-Atlantic coast hard, having already stormed across the Caribbean, killing at least …
