There clearly was not enough water in the Aquifer to meet current and future needs. In response to this water crisis, the Texas legislature created the Edwards Aquifer Authority and gave it extensive regulatory power to control pumping and to reallocate water through market mechanisms. Water marketing offers a means to minimize conflicts over the reallocation of water from lower economic valued agricultural uses to higher valued domestic, industrial, environmental and recreational uses. This article outlines a conceptual framework for a market-based water reallocation system and then applies this framework to the Edwards Aquifer region. The article suggests that there is a strong willingness on the part of stakeholders in the Edwards region to use markets to reallocate water and proposes an approach to encourage market development.

Based on this observation, we have decided to design our own interactive Web-based 3D crown preparation course. The course objective is to provide dental students with fundamental didactic and technical knowledge to begin preclinical skill development for full crown preparations. The course incorporates a variety of interactive features including images which allow students to examine the dimensions and contours of the burs in comparison to the dimensions and the shape of the crown preparation. QuickDraw 3D allows the direct manipulation of 3D graphical models by the users. This paper will relate experiences in the development and implementation of a Web-based course with 3D direct manipulation. An initial evaluation of the development process offers directions for further development, necessary technical support, and faculty and student preparation.

The objective of this study was to analyze the spatio-temporal trends of monthly evaporation at 52 weather stations in the state of Aguascalientes (Mexico) which have hydrometeorological records of long periods. The autocorrelation was eliminated with an auto-regressive model, and the trend was determined using the Spearman (S) and Kendall (K) tests. The statistical significance of the trend was determined with the Spearman correlation coefficient (r s) and the Z statistic (the test statistic of the normal distribution) both indicated that that there were statistically significant trends in 107 time series, of these 88 series had negative trends and 19 series had positive trends. Negative trends were present in all months of the year, while positive trends occurred from February to May and from October to December only. The reduction of evaporation from − 4.10 to − 20.50 mm/month/year from June to September showed a hopeful future scenario for rainfed agriculture. Irrigated agriculture during dry months could have a reduction of irrigation requirements as a consequence of the reduction in reference and crop evapotranspiration. The evaporation increase during dry months could increase irrigation requirements and pumping, mainly in March, April, and November when there are trends with increases of about 26.90, 24.60, and 23.90 mm/month/year, respectively. The spatial variability of evaporation trend means that other effects of climate change could vary in different parts of the state. Results of this study will be useful for farmers and institutions in charge of the administration of water resources for developing adaptation and mitigation strategies to climate change.

Reclaimed water reuse has historically been practised for potable use in the United States as de facto water reuse or unplanned indirect water reuse. The increasing number of planned indirect water reuse projects in the country and the approval of the first direct potable reuse projects have exposed the limitations of the regulatory system at the national and state levels. These limitations pose barriers and/or add uncertainty to the viability of potable water reuse.

Concern about closure of private, rural lands to outdoor recreation has been documented in the re... more Concern about closure of private, rural lands to outdoor recreation has been documented in the research literature for several decades. While many reasons for this phenomenon have been posited, liability for recreational injuries has been identified as a particularly worrisome problem for landowners. However, landowners' perceptions of liability are not commensurate with the reality of legal risks. This article examines rural landowner liability risks through an analysis of the 50 state recreation-use statutes intended to protect landowners from legal exposure tied to injuries sustained on their land. Further, data from the 637 appellate court cases heard since 1965 involving recreational injuries were compiled and analyzed based on the characteristics of the landowner (public or private), recreation activity pursued at the time of injury, and actual liability exposure. Although the focus of this article is primarily on the liability risks of private landowners and organizations, public agencies also are discussed. Recreation-use statutes are increasingly used in government defense, and cases provide more depth in understanding the reality of landowner liability. Recommendations to agencies concerned with access to private lands and suggestions for future research are included.
