Collaborative Research: Data Source and Data Quality Effects on Vadose Zone Transport Modeling

0440024Schaap本提案的目的是进行一项综合研究，其中可以容纳不同的数据源和数据质量水平以及不同的模型复杂性。 该项目建立在广泛的Marvila农业中心（AZ）网站数据可用。 本研究的目标是：1）使用多种不同的方法来测量现有监测点的土壤水力学和其他土壤特性，2）开发和评估土壤传递函数（PTFs），以使用一系列需要不同数量的特定站点数据的技术来估计该站点的土壤水力学特性，3）比较各种方法测定的水力学特性，以评估这些方法之间的差异性，4）进行分层建模研究，其中建立精确的一维、二维和三维场地水和溶质运移模型。

0440024SchaapThe objective of this proposal is to conduct an integrated study where different data sources and levels of data quality, as well as different model complexities can be accommodated. This project builds on extensive Maricopa Agricultural Center (AZ) site data available. The objectives of proposed research are to 1) use a number of different methods to measure soil hydraulic and other soil characteristics of an existing monitoring site, 2) develop and evaluate pedotransfer functions (PTFs) to estimate soil hydraulic properties for this site using a range of techniques that require varying amounts of site-specific data, 3) compare hydraulic properties determined using a variety of methods to asses the variability among these methods, 4) conduct a hierarchical modeling study in which accurate 1D, 2D and 3D site model for water and solute transport are established.
