    Week 2/4, 3/4 & 4/4 “LAST US-Mexico Border Water and Environmental Sustainability (UMB-WEST) Summer Campaign” 

    Hello Everyone!!!

    We finally got back to Tempe this past Saturday! We unloaded the equipment and went home. I’m sure everyone was ready to sleep at least 12 hours. 


    Agua de Hermosillo Presentation

    We started week 2 with meeting professors and students from different universities of Mexico. We attended many talks with government officials from Sonora, Mexico. As you can see on the left we met with Agua de Hermosillo, which they administer the public water of Hermosillo, Sonora. We also were invited to visit the vineyard of Grupo Alta, and we learned so much about the grape agriculture. More specifically, we learned that just by looking at a leaf we can identify which nutrients the plant is needing, such as potassium, magnesium, and others. Down below you can see the group picture with the Grupo Alta workers.

    During week 2 we also visited the Independencia aqueduct reservoir, el Novillo dam, the Distrito de Riego del Valle del Yaqui, and we had several talks addresing Sonoran water issues. Something very unique we were able to do was to visit the manglar de la Huivulai via boats. You can see a group picture of everyone super happy down below.

    Week 3 consisted of field work in Rayon, Sonora. The 14 experiments are as follows:

    1. Rayon tower weir construction
    2. Topographic survey
    3. Isotopic partitioning of evapotranspiration at an agroecosystem
    4. Stomatal conductance of plants
    5. Plant water potential
    6. Daily soil moisture/ temperature sampling
    7. Set-up mobile eddy covariance
    8. Balloon and quadcopter imagery
    9. Field spectrometer sampling
    10. Sap flow measurements
    11. Throughfall, stemflow, and interception loss in oak forest
    12. Geophysical survey
    13. Community water use survey at San Miguel River
    14. Removal of hydrometereological stations in San Miguel basin

    At times we ran into difficulties with equipment not properly working, but we all worked as a team and got through the day. Below you can see pictures of several members working in different experiments.

    As of Week 4, the ASU members are in charge of putting away all of the field equipment and putting together a presentation that will be shown to the public sometime during the week of August 25th-29th. Please feel free to come and look-out for some of the flyers we will be posting around campus!


    This year was unforgettable and we learned so much about hydrology… ONE of a kind experience.

    Week 1/4 “LAST US-Mexico Border Water and Environmental Sustainability (UMB-WEST) Summer Campaign” 

    Hola a todos!!! (Hello everyone!!!)


    Several participants looking for equipment that we will be taking to Mexico!

    The preparation for the LAST campaign officially started this past Monday, July 21, 2014 at 9 am, to be precise. We have been successfully preparing for our trip to Sonora, Mexico which will last for two weeks. Professor Enrique Vivoni and 12 participants (undergraduate and graduate students from different backgrounds) will be traveling to Mexico this Sunday to accomplish several goals, which include:

    • Deploying instrumentation
    • Conducting field sampling
    • Visiting water infrastructure projects, and
    • Interacting with local water managers.

    I could go on and on about every little detail, but you can further read and learn about the UMB-WEST 2012 and 2013 Campaigns by clicking on this link. I want to focus more about the experiences and challenges that make the 2014 UMB-WEST Campaign unique. 


    Quad-copter! Takes aerial images with a high resolution.

    This year we are using a Quad-copter for the first time! We plan on taking aerial pictures of the sites, and you can see an image of it on the left <——. Something very neat about the instrument is how it can be controlled with your cellphone by simply downloading a free app! All of the participants are learning how to use the equipment that will be used to perform the different experiments in Mexico. Some of the experiments that will be completed in the next two weeks entail constructing a weir, setting up a mobile tower, complete a topographic survey, recover stations that were installed in previous years, and pass out surveys to local Sonoran neighborhoods to know their opinion in regard to water issues.

    Additionally, we have been learning about GIS mapping through ArcMap and the end result can be seen in our Facebook page. The HEC-HMS hydrological model was also taught to the participants by Dr. Ted Bohn, Enrique’s Post-Doc student.

    I am very excited to be part of this team because everyone is very enthusiastic, positive, and prepared to solve any problem we might run into. We are working together as a team and getting things done efficiently. Week 2 will consist of mainly meeting Mexican officials who make the decisions about water issues in Sonora, so I will basically be the reporter of the week. Hopefully I have internet access to publish the “hot” topics that are brought up during the presentations, if not once we come back from Mexico I will publish it!

    Cuidense y espero lean el proximo blog (Take care and hopefully you read the next blog)

    See you later Tempe!!!
