Progress 04/16/20 to 09/30/20
Outputs
Target Audience:For the reporting period starting April this year. Wehave connected with several small growers in the region. We have identified three plots, and have partnered withthe growers, to collect data next growing season for model development and data collection. Changes/Problems:Due to COVID 19 restriction, some planned data collection using UAVs and Remote Sensing was postponed. These operations are expected to start next year. What opportunities for training and professional development has the project provided?

What do you plan to do during the next reporting period to accomplish the goals?1. Develop a water-salt interaction model for agricultural applications. A model has been developed. We plan to update the model to better represent desalination in agriculture, integrate fertilizer and other amendment applications for cotton and pecan in the next reporting period. 2. Develop methods that convert remote sensing to actionable data products. We have identified three sites, monthly remote sensing data (multispectral, hyperspectral, and thermal) data will be collected for the three sites for the next growing season. These datasets will then be analyzed and converted to data products (e.g., spatially distributed Evapotranspiration) that may be utilized by growers. 3. Develop an agroecosystem model that can assimilate remotely sensed data products. The model developed in objective1 will be enhanced to assimilate the evapotranspiration (ET). ET will be observed using thermal remote sensing and also simulated using the model. The observed ET will be assimilated to better characterize other differences in the parameter that may not be easily measured (e.g, spatial heterogeneity within a field for salt accumulation) 4. Apply integrated systems modeling approaches for the arid regions to explore interactions with other systems and enable OneWater thinking. Continue developing system models that are being developed to explore transboundary water usage and energy-water nexus. 5. Work with selected multi-state projects: a. S1069: Research and Extension for Unmanned Aircraft Systems (UAS) Applications in U.S. Agriculture and Natural Resources The team will coordinate with other participants to synergistically develop methods and protocols. As discussed in item 2, monthly multi-sensor remotely sensed data will be collected next growing season. Will also participate in the annual meetings. b. SDC101: Advanced Understanding and Prediction of Pollutants in Critical Landscapes in Watersheds. The team will coordinate with other participants to synergistically develop methods and protocols.
Impacts
What was accomplished under these goals?
1. Develop a water-salt interaction model for agricultural applications. A model, SMITUV (System Dynamic Modeling of Infiltration, Solute Transport, and Root Water Uptake in Vadose Zone) was developed for simulating transient soil water flow, solute transport, and root water uptake in crops under water and salinity stress in a multilayered unsaturated soil layer. The model is been actively updated to better simulate the salt-water interactions in arid regions with flood irrigations. 2.Develop methods that convert remote sensing to actionable data products. Some data collection was conducted this season to develop a standard protocol for data collection. Data collection will start next growing season. 3. Develop an agroecosystem model that can assimilate remotely sensed data products. A model framework has been developed, that will be updated based on data products. 4. Apply integrated systems modeling approaches for the arid regions to explore interactions with other systems and enable OneWater thinking. System models are being developed that explore transboundary water usage and energy-water nexus. For transboundary water usage, working with partners, a system model is under developementthat will be able to simulate the dynamics of surface water and groundwater consumptions by various sectors (e.g., agriculture, municipal, and industrial) in both Mexico and the United States. This model should aid integrated water management and also help understand the expected demands in the future given the changes in long-term climate, growing cities, and expected changes in deep aquifer salinity. A proposal was submitted to develop a system model with partners from NMSU and UTEP to develop a holistic view of the energy and water resources in the arid region. Particular emphasis was placed on salt cycling and its feedback to the water quantity and consumptive use. 5. Work with selected multi-state projects: a. S1069: Research and Extension for Unmanned Aircraft Systems (UAS) Applications in U.S. Agriculture and Natural Resources Three research field siteshave been identified and a proposal was developed for S1069 that has been accepted. b. SDC101: Advanced Understanding and Prediction of Pollutants in Critical Landscapes in Watersheds. A proposal was developed with participants from Virginia Tech and other members of the Texas A&M AgriLife team that is looking to understand the socoenvironmental dynamics of the blue-green infrastructure design. Particularly by integrating social and environmental domains.
