Hydrology and Restoring Ecosystems


Hydrology and Restoring Ecosystems: Applications in Engineering and Earth Sciences

By Julia McKeag, MSS Intern, Terra Linda High School

We are water. Well, anywhere from sixty to eighty percent of our body anyway. We may be mostly water, however, our body still requires a daily intake of this substance. Not saltwater, not marsh water, not swamp water, not muddy water, not vitamin water, but clean, fresh, water. This need has been known since the beginning of time, an instinct stored within the very fiber of human being, and has resulted in many conflicts.
One of history’s famous “water wars” occurred between the farmers and ranchers of Owens Valley and the City of Los Angeles. In the 1800s, when Los Angeles outgrew its local water supply, the city searched for a new source of water. The mayor of Los Angeles, Fred Eaton, suggested that water from the Owens Valley could be diverted by aqueduct to Los Angeles. Owens Valley, a once fertile agricultural environment, supported various species of migrating birds, farms, and businesses. Naturally, Owens Valley inhabitants were outraged when their once fecund valley dried up into a second Mojave. The balance between the need for water, and the preservation of environment and agriculture was not reached, leaving some discouraged and many angered. 
  
This is where the study of hydrology comes into place. The field of hydrology not only concerns the sciences, but also the environment, politics, and public health. We have genius engineers and inventors, such as Archimedes and Louis Pasteur to thank for making modern society possible. However, the job of a true hydrologist requires more than engineering skills. Rachel Z. Kamman, a consulting hydrologist at Kamman Hydrology & Engineering, not only holds a B.S. in Civil Engineering from Lafayette College, but also an M. Eng., in Hydraulics, Coastal Engineering, Hydrology and Geomorphology from UC Berkeley.
The work of Kamman Hydrology and Engineering (KHE) focuses mainly on ecological habitat restoration, and revolves around projects involving fishery, wetlands, and riparian habitats. KHE has projects throughout California, most of which are on public land. In the words of Ms.Kamman, “We can not turn back time, (so) KHE works to understand how the landscape has changed and how best to improve, restore or protect ecological communities in the context of people and their infrastructure. Since water is fundamental to nature, understanding the landscape in terms of hydrology is a logical starting point for both evaluating the impacts of change and restoring ecological function.”
Ms. Kamman believes that one of the biggest problems affecting local watersheds is that people are disconnected from their environment. If people don’t realize that their actions are directly linked to the health of a local watershed, people won’t think twice about what goes into the storm drain. Fertilizers, Paint, and Soap are all deposited directly into the nearest creek or bay when vacuumed into a storm drain. 
     
Overall, the work hydrologists such as Rachel Z. Kamman is crucial to the structure and function of our society today, and a healthy watershed is critical to a healthy and functioning community. Without advances in hydrology and engineering, our society would be eons behind what it is today.

Invention in Medicine this Wed. 10/26/16

Marin Science Seminar for Teens & Community Presents Invention in Medicine How Medical Devices get Invented and Go to Market with Art Wallace MD PhD of UCSF & VAMC SF
Wednesday, October 26, 2016 7:30 - 8:30 pm Terra Linda High School, Room 207 320 Nova Albion, San Rafael, CA 94903 


Art Wallace started out in experimental surgery and radiology studying imaging of the heart using CT
scanners. He has worked on a number of devices that originally were built for experimental studies that evolved into clinically useful devices including a cardiac output monitor, the off pump CABG, off pump aneurysm surgery, electronic sedation, and a selective coronary vasodialtor. Dr. Wallace will explain his experiences with the inventive process using examples from both device design and drug development. There will be a brief discussion of the importance of intellectual property, patents, venture capital, FDA approval, and business development in completing the invention process. There will …

An Interview With Diara Spain, Ph.D

By Rachael Metzger, MSS Intern

Ocean acidification is an issue becoming apparent in the effects on both sea creatures and humans. Diara Spain, the Associate Professor of Biology at Dominican University, came to Marin Science Seminar to talk to us about her studies in marine invertebrates and the damage ocean acidification is causing them. 

To learn more about Diara Spain and what inspired her studies we conducted an interview:


1. How did you get interested in biology? Is there a time, event, 
or person in your life that inspired you to pursue the study? I've always been interested in biology, really science in general. I grew up in rural North Carolina and as a kid it was expected that you'd spend most of your free time outside playing with your friends and pets.  One thing that sparked my interest in marine organisms were the summer vacations at the undeveloped beaches in North Carolina. 
2. Why did you specifically decide to focus on functional morphology, locomotion in echinode…

Marin Science Seminar Internships Still Available

Marin Science Seminar still has two high school student internship spaces available. Interns must be able to attend science seminars on select Wednesday evenings at Terra Linda High School in San Rafael. Interns arrive at 7 pm to set up, assist with the seminar, and can leave when the seminar is cleaned up by 8:45 pm. Specialties are also available for students interested in writing, photography, videography, and social media.
