A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long-term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analyses. Depletion is directly calculated using calibrated groundwater models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900–2008 totals approximately 1,000 cubic kilometers (km3). Furthermore, the rate of...

Aucune base de données ne disposait du positionnement numérique des ports. Les ports fluviaux correspondent à des noeuds des [axe_hydro]. Ils ont été positionnés par comparaison entre le fichier des localités transmis par la MONUC et, soit la carte des ports transmis par la RVF, soit le listing des ports transmis par la SNCC. En l’absence de ville ou de village portant le nom du port, le noeud a été créé en référence au PK transmis par la SNCC ou la RVF. Le positionnement des ports fluviaux a été fait au sein de l’agence UNJLC de Kinshasa en 2006. No database gives a numerical position of ports. The fluvial ports correspond to nodes on the hydrologic axes. They are positioned by comparisons between the local data...

The Hydrology Point Feature Class defines natural/semi natual point hydrographic features (springs, seeps, tanks, guzzlers…) on RSL. The data for this point feature class was provided by the refuge.
What are current conditions for important park natural resources? What are the critical data and knowledge gaps? What are some of the factors that are influencing park resource conditions? Natural Resource Condition Assessments (NRCAs) evaluate and report on the above for a subset of important natural resources in national park units (hereafter, parks). Focal study resources and indicators are selected on a park-by-park basis, guided by use of structured resource assessment and reporting frameworks. Considerations include park resource setting and enabling legislation (what are this park's most important natural resources?) and presently available data and expertise (what can be evaluated at this time?). In addition...

Natural landscapes in the Southwestern United States are changing. In recent decades, rising temperatures and drought have led to drier conditions, contributed to large-scale ecological impacts, and affected many plant and animal species across the region. The current and future trajectory of climate change underscores the need for managers and conservation professionals to understand the impacts of these patterns on natural resources. In this regional assessment of the Southwest Climate Change Initiative, we evaluate changes in annual average temperatures from 1951–2006 across major habitats and large watersheds and compare these changes to the number of species of conservation concern that are found within these...

Rainwater Harvesting and Stormwater Research is a priority research area identified by the Arizona Governor’s Blue Ribbon Panel on Water Sustainability, which recommended that universities take the lead to identify regulatory barriers, cost and benefits, water quality issues and avenues for increasing utilization of stormwater and rainwater at the regional, community and individual property level. In an effort to address the priority research area, the University of Arizona will develop a decision support tool to be used by public utilities and agencies to evaluate suitability and cost-effectiveness of rainwater and stormwater capture at various scales for multiple benefits. Data from the City of Tucson, Arizona...

This dataset represents the soil water storage capacity (AWS in mm at 0.25 m depth) from SSURGO and STATSGO soil descriptions for soil map units in the state of southern Alaska that lie within the North Pacific Landscape Conservation Cooperative. Available Water Storage 0-25 cm - Weighted Average (centimeters). Available water storage (AWS). The volume of water that the soil, to a depth of 25 centimeters, can store that is available to plants. It is reported as the weighted average of all components in the map unit, and is expressed as centimeters of water. AWS is calculated from AWC (available water capacity) which is commonly estimated as the difference between the water contents at 1/10 or 1/3 bar (field capacity)...

This dataset represents the soil water storage capacity (AWS in mm at 0.5 m depth) from SSURGO and STATSGO soil descriptions for soil map units in the state of southern Alaska that lie within the North Pacific Landscape Conservation Cooperative. Available Water Storage 0-50 cm - Weighted Average (centimeters). Available water storage (AWS). The volume of water that the soil, to a depth of 50 centimeters, can store that is available to plants. It is reported as the weighted average of all components in the map unit, and is expressed as centimeters of water. AWS is calculated from AWC (available water capacity) which is commonly estimated as the difference between the water contents at 1/10 or 1/3 bar (field capacity)...

This dataset contains stream-stage data for Santa Cruz River at Tumacácori Downstream Site (SC11). The pressure transducer was mounted to a metal post secured in the stream near the left bank. The data were recorded using non-vented Solinst Levelogger for the period of June 16, 2016 to June 24, 2016. The data were logged continuously at a 15-minute interval and manually downloaded. Data were then corrected with the atmospheric pressure collected from a Solinst Barologger located at SC14. The data was processed and analyzed for erroneous data.

The Pima County Information Technology Department is pleased to introduce PimaMaps, Pima County's next generation web mapping system that will eventually replace the current MapGuide system. The Main MapGuide Map, will remain available for a substantial amount of time while PimaMaps is fully implemented. While MapGuide has been a very reliable web mapping system for many years, it is no longer supported by Autodesk. PimaMaps is based on new technology, provides a more robust and modern interface comparable to Google and Bing, and offers a richer set of functionality beyond what is available with MapGuide. This version of PimaMaps has the following functionality and enhancements that are not available with MapGuide:...
