Drought, groundwater use, and subsidence in California

As California’s drought continues and intensifies, groundwater is ever more heavily exploited. Groundwater withdrawals are happening much faster than natural recharge will ever occur, and the consequences can literally move the ground beneath your feet. This video from the USGS is a nice explainer:

For more on California’s climate and water woes, check out my review of the book “The West Without Water,” which was published last spring in Earth Magazine.

Damnation film screening in Cleveland on Wednesday

If you haven’t seen it yet, and you are at all interested in dams and dam removal (or are even wondering why people would be interested in dam removal), I encourage you to watch the film Damnation. The film highlights some of the environmental issues associated with dams, showcases the growing movement to get them removed, and shows us the results when dams do come out. Plus, it features gorgeous scenery of Pacific Northwest Rivers. So check out the screening in Cleveland this week (info below) or ask Anne how to get access to her copy of the film.

Here’s the trailer:

The award-winning documentary, Damnation, is coming to Cleveland’s Capitol Theater on Wednesday, September 24th at 7 p.m. The movie tells the story of the use of dams around the United States and the impact that dams have on rivers. It was produced by Yvon Chouinard who, among many other conservation accolades, is the founder of Patagonia.

Kdudley Media is hosting the presentation of the movie at the Capitol and they have graciously invited Friends of the Crooked River to be their special guest. FOCR will have an informational display in the lobby before the showing and have a Q&A session after the movie focusing on local dam removal efforts. In addition, Kdudley has decided to donate any funds raised from the showing of the movie to FOCR in support of our conservation efforts. Here is a link to more information about the film:

Tickets will be available at the door, as well as on line.

The Capitol Theater is located at W. 65th and Detroit in Cleveland’s District, Gordon Square District. This area is also home to several good restaurants ranging from casual to upscale so you may want to come early and make a night of it.

Hope to see you on September 24th

Social Hour at 6 PM

Film at 7 PM

Q&A concerning dams on the Cuyahoga following show

Radar precipitation measurements

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 totalsThis page gives a seamless map of 1-day precipitation totals for the US, derived from radar measurements. Pretty sweet! The videos below give more information on ground-based and space-based radar rainfall applications.


Or in space:

The upcoming launch of the Global Precipitation Measurement (GPM) satellite will greatly expand space-based precipitation measurements. The launch is currently scheduled for the 27th of February, but there is a media event on NASA TV on Monday, January 27th.

Also, follow @NASA_Rain on twitter to learn about the upcoming Global Precipitation Mission launch and the science behind it.


The Cuyahoga Falls dam removal video you’ve been waiting for

Cross-posted at Highly Allochthonous

This summer we were treated to not one but two dam removals on the Cuyahoga River, ~10 miles downstream from Kent. Those following me on twitter know that I obsessed about these removals all summer long, first as they were delayed by weeks of high water, then as they got started and I got to watch first on the live “dam cam” and then in person. But the video compresses a whole summer of waiting, watching, and obsessing into two and a half glorious minutes, complete with music. This is, without a doubt, what youtube was invented for.*

If that dam removal video merely served to whet your appetite for dam busting, I have a few other videos you might enjoy. First, there’s there’s an excellent 8 minute documentary on Marmot Dam on the Sandy River, Oregon, which explains the science that led up to this removal, features the excitable Gordon Grant, and shows the action unfolding. If you just want to cut to the action, you can’t beat the “blow and go” (that would be the technical term) of the Condit Dam removal in Washington. Finally, a feature length movie called DamNation is coming our way in 2014. I’m so excited, I can hardly stand it. I’m going to go watch the videos a few more times.

*Youtube was also invented for flash flood videos, videos of people running rapids on the Grand Canyon, the Lake Peigneur disaster video, and corny videos produced by sewer districts about CSOs.

Lost Rivers documentary showing in Kent!

I’m super-excited! Super super excited. I’ve just found out about a new documentary on Lost Urban Rivers! The trailer looks great (see below). And it’s showing in Kent! This week!

Lost Rivers is a new documentary by Montreal-based Catbird Films, and it tells the story of how cities built around water, then built over it “losing” the rivers, and how today we are starting to uncover those rivers again. The film was released earlier this year, and there’s only been two other screenings of it in the US so far. And totally unbeknownst to me, the third US screening is here in Kent, Ohio on Friday (April 19th) as part of the Who’s Your Mama? Environmental Film Festival. The film festival runs from 5 to 9 pm, with lots of great shorts, and Lost Rivers is the featured documentary, which will show at 7:30 pm. The film festival is in the Kiva on the Kent State Campus, and admission is $7, $5 for students and seniors, or free for kids under 12. There will also be local food tastings and booths by local environmental organizations, including Kent State’s student group CRICK.

Doesn’t it look great? I’ll definitely be at the screening on Friday, and I hope I’ll see some of my students there as well (though I know many will be on a field trip). In any case, I’ll report back, but I’m hopeful that by the next time I teach Urban Hydrology, I’ll have a copy on DVD and be able to show it to my class. Whee!

Condit Dam Removal video

No excited Gordon like at Marmot Dam, but this is one exciting “blow and go” dam removal video. This was Condit Dam on the White Salmon River in Washington in October 2011. Spectacular to watch, and even neater knowing that there was important (and hair-raising) science being done both upstream and downstream of the dam throughout the dam removal process.
