PostDoctoral Research Fellowship

现申请正在进行的少数民族博士后资助项目“传统治水技术建模：洪水与渗流场”（0109216）延期一年。该项目的目标是开发方法来确定美国西南部史前农业领域生产力的潜在位置和气候限制。其他好处包括有助于开发节水旱地农业技术的信息。通过在亚利桑那州北部的四个研究地点对霍皮族农民的传统农业技术和水文进行研究，实现了这些目标。通过采访和参与手工种植活动，补充了以前关于霍皮农业的文献资料。对传统农田的地貌和土壤学分析与气候和土壤湿度监测相结合，以确定对农业生产至关重要的水汽带水文过程。迄今为止，研究揭示了传统霍皮农业技术与农业领域水文过程之间相互作用的新认识。然而，由于漫长的许可过程、对完全手工耕种的田地的长期搜索、2002年的极端干旱，以及在拟议的两个地点之外增加两个监测研究地点，数据收集和分析将受益于一年的延长。这个提案描述了项目的成就和额外一年学习的好处。本材料基于美国国家科学基金0109216号拨款和霍皮人水资源计划支持的工作，并通过包括DS， EN， RL和WK在内的霍皮农民的善意进行。

This proposal requests a one-year extension for the on-going Minority Post-Doctoral Fellowship project entitled "A Modeling Traditional Water Control Technologies: Floodwater and Seepage Fields" (0109216). The goal of the project is to develop methods to determine potential locations and climatic limits on productivity of prehistoric agricultural fields in the American Southwest. Additional benefits include information that can aid development of water-efficient arid-land agricultural technology. Goals are accomplished through study of the traditional agricultural technology and hydrology of Hopi farmers in four study sites in northern Arizona. Previously documented information on Hopi agriculture is supplemented by interviews and participation in hand-cultivation activities. Geomorphic and pedological analyses of traditionally farmed sites are integrated with climate and soil moisture monitoring to determine vadose-zone hydrologic processes vital to agricultural production. Thus far, research has revealed a new understanding of the interactions between traditional Hopi agricultural technology and hydrologic processes in agricultural fields. However, due to a long permitting process, a long search for completely hand-cultivated fields, the extreme drought of 2002, and addition of two monitored study sites beyond the proposed two sites, data collection and analysis will benefit from a one-year extension. This proposal describes project accomplishments and the benefits of an additional year of study. This material is based upon work supported by the National Science Foundation under Grant No. 0109216 and the Hopi Water Resources Program, and conducted through the kindness of Hopi farmers, including DS, EN, RL, and WK.
