The water regime on the reclaimed lands changes significantly during the year, and its possible change must be established or predicted in advance at the project stage. From the main characteristics of the water regime of soil, it is possible to reliably predict changes in moisture reserves and, worse, the dynamics of groundwater levels. Prediction of changes in moisture reserves in soil is carried out using “water balance calculations”. The results of long-term field research have shown that the main factors causing surface runoff are: the amount and intensity of precipitation, the initial moisture content of the upper soil layers, the slope and condition (agricultural use) of the site surface. The feasibility of using a variable runoff boundary in calculating the water balance of ameliorated soil is shown. The results of field experiments on the study of surface runoff in conditions of loamy soil are presented. Two-factor dependences of the daily runoff from precipitation and soil moisture have been obtained in case of its various agricultural uses.

В настоящей статье автор, преимущественно на материалах собственных многолетних полевых исследований, рассматривает в контексте современности малоизученную традиционную практику хлебопроизводства в Сардинии. Анализ особенностей этого древнейшего сектора локальной культуры он предваряет освещением специфики истории региона и принципов расселения в нем, значительно повлиявших на множественность разнообразных «типажей» хлеба, как повседневных, так и праздничных, показывает специфику их иконографии и декорирования, отличия их рецептуры и технологии производства, их «привязок» к конкретным поводам, событиям, верованиям и ритуалам. Помимо этнографической части, в исследовании присутствуют теоретико-методологические аспекты: автор задается вопросом о несовершенстве существующих систем классификации сардинских хлебов, о нерешенности вопроса их таксономирования и, апеллируя к примеру эмпирического материала Сардинии, предлагает иные пути и подходы к систематизации в антропологическом исследовании в целом, а в частности, переход от «монотетической» классификации к ретикулярной, ризоматической систематизации Based mainly on the author’s long-term field research, this article examines the littlestudied traditional practice of bread production in Sardinia in the context of modernity. The analysis of this, the oldest sector of local culture, is preceded by a history of the region and the nature of its settlement which influenced the multiplicity of various types of bread, both everyday and festive. The article explains the specifics of bread’s iconography and decoration, differences in recipes and technology of production, and its links to specific occasions, events, beliefs and rituals. In addition to ethnographic analysis, the study examines theoretical and methodological issues. The author considers problems with existing classification systems of Sardinian bread, discusses the unresolved issue of their taxonomy, and questions the general approach to systematization in anthropological research, and in particular, the transition from “monotheistic” classification to reticular, rhizomatic systematization. Key words: Sardinia, Mediterranean, bread, cooking technologies, species diversity.

The Field Research & Conservation class emphasizes long-term field research experiences, examines ecosystem processes, and investigates the evolution of American perspectives about nature. Our time spent at the UW-NPS research station was divided between pursuing behavioral ecology research and exploring Grand Teton National Park and the surrounding area to gain understanding of how the region was shaped, both by geological and biological process as well as political processes that have been shaped by America’s ever-changing conservation ethic.
