Fusion of Time-Lapse Gravity Survey and Hydraulic Tomography for Estimating Spatially Varying Hydraulic Conductivity and Specific Yield FieldsTsai, Jui-Pin; Yeh, Tian-Chyi Jim; Cheng, Ching-Chung; Zha, Yuanyuan; Chang, Liang-Cheng; Hwang, Cheinway; Wang, Yu-Li; Hao, Yonghong; Univ Arizona, Dept Hydrol & Atmospher Sci; Department of Civil Engineering; National Chiao-Tung University; Hsinchu Taiwan; Key Laboratory for Water Environment and Resources; Tianjin Normal University; Tianjin China; Department of Civil Engineering; National Chiao-Tung University; Hsinchu Taiwan; State Key Laboratory of Water Resources and Hydropower Engineering Science; Wuhan University; Wuhan China; Department of Civil Engineering; National Chiao-Tung University; Hsinchu Taiwan; Department of Civil Engineering; National Chiao-Tung University; Hsinchu Taiwan; Department of Hydrology and Atmospheric Sciences; The University of Arizona; Tucson AZ USA; Key Laboratory for Water Environment and Resources; Tianjin Normal University; Tianjin China (AMER GEOPHYSICAL UNION, 2017-10)Hydraulic conductivity (K) and specific yield (S-y) are important aquifer parameters, pertinent to groundwater resources management and protection. These parameters are commonly estimated through a traditional cross-well pumping test. Employing the traditional approach to obtain detailed spatial distributions of the parameters over a large area is generally formidable. For this reason, this study proposes a stochastic method that integrates hydraulic head and time-lapse gravity based on hydraulic tomography (HT) to efficiently derive the spatial distribution of K and Sy over a large area. This method is demonstrated using several synthetic experiments. Results of these experiments show that the K and Sy fields estimated by joint inversion of the gravity and head data set from sequential injection tests in unconfined aquifers are superior to those from the HT based on head data alone. We attribute this advantage to the mass constraint imposed on HT by gravity measurements. Besides, we find that gravity measurement can detect the change of aquifer's groundwater storage at kilometer scale, as such they can extend HT's effectiveness over greater volumes of the aquifer. Furthermore, we find that the accuracy of the estimated fields is improved as the number of the gravity stations is increased. The gravity station's location, however, has minor effects on the estimates if its effective gravity integration radius covers the well field.
Evaluation of Hydrologic and Hydraulic Procedures for Small Urban Watersheds in the SouthwestLane, L. J.; Ward, T. J.; Stone, J. J.; USDA, ARS Southwest Rangeland Watershed Research Center, Tucson, AZ 85719; New Mexico State University, Las Cruces, NM 88003 (Arizona-Nevada Academy of Science, 1985-04-27)Hydrologic and hydraulic design procedures developed by the Pima County Department of Transportation and Flood Control District were proposed for use by the Department of Transportation, Engineering Division of the City of Tucson, Arizona. These procedures were evaluated with respect to their reasonableness of approach and in comparison with other methods and existing data used to derive similar methodology and standards. The proposed criteria/methodology were found to be consistent with procedures used in other cities in the Southwest, and with the current state of the art in urban hydrology and hydraulic engineering practices and procedures. However, locally derived rainfall intensity -duration relationships were found to be superior to regionally based relationships, and minor modifications were suggested for channel design procedures.
