Surface-water models are being developed to simulate streamflow at existing USGS gaging stations and other ungaged locations in and upstream of the Coastal Basins of the Carolinas. The models will be used to simulate the potential effects of projected changes in water-use, climate, and urbanization through the year 2065. The Soil and Water Assessment Tool (SWAT) is being used to develop the models. The SWAT model is a physically-based watershed model with the capability of incorporating water-use data. The model operates on a daily time step, which is necessary to support the data input requirements of future ecological response modeling. The models are being calibrated to the period 2000-2014 and will subsequently...

Innovative Conservation incentives beyond easements and fee simple purchase are needed for conservation in Florida. In east central Florida, citrus farm owners and agencies have developed a method of storing additional water on shallow citrus groves called water farming. This water storage will help remove harmful point source discharges to the Indian River Lagoon. In support of the development and implementation of wildlife regulatory assurance for Dispersed Water Management (DWM) projects in the Northern Everglades, especially for Water Farmers in the St. Lucie River and Estuary Watershed, the PI provided coordination to support development of a multi-party agreement among USFWS, FWC, FDACS, SFWMD, SJRWMD, and...

This dataset describes irrigation water use in Kansas in 2015. Volumes of water used, irrigated area, and average irrigation application depths are provided for three sets of subareas: (1) Irrigation water use analysis regions that include Groundwater Management Districts (GMDs) with the areas outside of GMDs divided into eastern, central, and western Kansas; (2) Regional Planning Areas (RPAs), which are 14 areas determined by the Kansas Water Office based on hydrologic and administrative boundaries, each with a set of goals outlined in the Kansas Water Vision (https://kwo.ks.gov/water-plan/water-vision); and (3) the 105 Kansas counties. Volumes of water used, irrigated area, and average application depths are also...

Global change processes are producing shifts in temperature, precipitation, and seasonal streamflow regimes across North America. Much of the floodplain hydrology in the U.S. is managed through water control operations, often implemented on short time scales (e.g., weekly decisions), in response to short-term changes in precipitation. This operational model does not account for potential long-term trends, such as increased recurrence or shifts in seasonal timing of high flow events within a year. Therefore, polices that only focus on short-time scales and recent historic conditions may not perform as well under altered climate regimes. This uncertainty in future floodplain conditions is concerning for a variety...

This U.S. Geological Survey (USGS) Data Release represents geospatial and tabular data on irrigation water use in Kansas. The data release was produced in compliance with open data requirements. The dataset consists of 3 separate items with similar attributes aggregated to different geographic extents: 1. Kansas counties; 2. Kansas regional planning areas used in the Kansas Water Plan; and 3. Kansas irrigation water-use analysis regions. Reported 2014 water withdrawn for irrigation, acres irrigated, and application rates along with the published application rate statistics from the previous 4 years (2010–13) are shown with the 2014 statistics and are used to calculate a 5-year average. The 2014 annual total...

Surface-water availability has been identified as one of the biggest issues facing society in the 21st century. Where and when water is on the landscape can have profound impacts on the economy, wildlife behavior, recreational use, industrial practices, energy development, and many other aspects of life, society, and the environment. Projections indicate that surface-water availability will be generally reduced in the future because of multiple factors including climate change, increased drought frequency and severity, and altered water and land use. Thus, it is important resource managers understand which areas are most vulnerable to reduced water availability impacts, and to what extent current conditions may...

Soil water dynamic is a crucial factor for understanding water-limited, arid to semiarid ecosystems (Porporato et al. 2002, Loik et al. 2004, Lauenroth and Bradford 2006), which cover c. 30% of global land area (Peel et al. 2007). The spatial and temporal patterns of available water, i.e., the amount of soil water that is extractable by plants, is a major determinant of aboveground net primary production and plant functional composition (Noy-Meir 1973, Sala et al. 1988, Sala et al. 1997). Climatic conditions including precipitation, temperature and potential evapotranspiration (PET), which are frequently summarized in climate diagrams (Fig. 1a, Walter and Lieth 1967), explain general patterns of soil water availability...

Clouds often come in contact with vegetation (often named fogs) within a certain elevation range on Hawaiʻi’s mountains. Propelled by strong winds, cloud droplets are driven onto the stems and leaves of plants where they are deposited. Some of the water that accumulates on the plants in this way drips to the ground, adding additional water over and above the water supplied by rainfall. Prior observations show that the amount of cloud water intercepted by vegetation is substantial, but also quite variable from place to place. It is, therefore, important to create a map for the complex spatial patterns of cloud water interception (CWI) in Hawaiʻi. In this project, we proposed to create the CWI map at 0.8-km resolution...

As the predicted impacts of climate change are becoming more apparent, natural resource managers are faced with the task of developing climate adaptation plans. These managers need state-of-the-art, scientifically based information upon which to base these management plans and decisions consistently across California and the Great Basin. This project applies historical, current, and projected climate data to a regional water model to examine water availability, biodiversity, and conservation. Analysis of this climate and hydrology data is expected to help managers understand areas in the region and landscape where the effects of climate change are expected to be the most profound. The study also addresses how the...

Managing water resources in arid regions is increasingly important in the face of more frequent droughts and desertification that is occurring with climate change. These challenges of climate change intersect with potential environmental contamination from naturally occurring sources and legacy human activity (such as mining) and create a need for sustainable land and water management planning solutions. This project aims to help create sustainability plans by involving and training the community and by making water resource data accessible and available. The project is a collaboration between the University of Arizona Indigenous Resilience Center, the Southwest Research Information Center, and local communities...

Mountain meadows in the western United States provide key habitats for many plant and wildlife species, many of which rely exclusively on these areas. Mountain meadows are also treasured by the public and provide beautiful areas to view wildflowers and wildlife on public lands such as national parks. However, mountain ecosystems are expected to be disproportionately affected by climate change. There is a limited understanding of how mountain meadows are changing, how temperature and precipitation may be driving those changes, and how this will impact sensitive species that inhabit these landscapes. Natural resource managers have an immediate need to understand these relationships to conserve or restore habitats...

FY2017Removal of livestock grazing is a common prescription to promote ecosystem recovery after wildfire (and subsequent emergency site rehabilitation efforts). Ecosystem recovery is typically considered from a terrestrial perspective, but wildfire and grazing can strongly influence aquatic ecosystems as well, especially smaller and fragmented stream networks, which are prevalent in the Great Basin (Minshall et al. 1989[1]; Dunham et al. 2003[2]; Luce et al. 2012[3]). Understanding these influences is essential for managing fire and grazing. Examples include identifying timeframes for resuming livestock grazing following wildfire, and the interactions between livestock grazing, fuels, and recovery of stream-side...

Estimates of water flows in streams are critical to inform natural resource managers of water availability for both human and ecological needs. Monitoring flow in the stream using a streamgage provides information about the amount and timing of surface water resources. However, not every stream has a streamgage and decisions about water resources may need to be made in a watershed where there is no flow information. Hydrologic models can be used to provide estimates of streamflow in the absence of streamflow information. These models depend upon available streamflow data for calibration, and can be very inaccurate without the use of those data. This research developed a method to group watersheds that are gaged...

Droughts in the Hawaiian Islands can enhance wildfire risk, diminish freshwater resources, and devastate threatened and endangered species on land and in nearshore ecosystems. During periods of drought, cloud-water interception, or fog drip (the process by which water droplets accumulate on the leaves and branches of plants and then drip to the ground) in Hawai‘i’s rain forests may play an important role in providing moisture for plants, reducing wildfire risk within the fog zone, and contributing to groundwater recharge (the process by which water moves downward from the surface through the ground to the groundwater table) that sustains water flow in streams during dry periods. Estimates of the changes in water...

A major component of the Water Census is the National Water Census Data Platform, which enables integration and delivery of water budget information alongside other data of interest to managers, such as water use data or ecological assessment criteria. Eventually, end users of water budget data (i.e. management agencies and decision-makers) will be able to access an integrated system of online databases in a form that will enable them to construct local and regional water budgets.

Background information.—Historically, the Powell River supported abundant and diverse populations of freshwater mussels. In recent decades, mussel density and species richness have declined and many freshwater mussel species are listed as either State or Federally threatened or endangered species. Environmental degradation from coal mining has been identified as one of the drivers of this decline. An example is the 1996 Lone Mountain slurry spill that directly affected mussel populations, as well as their host fish species. Freshwater mussels feed by filtering small particles from water, thereby improving water quality and providing an essential ecosystem service in rivers and streams. Mussels also serve as a food...

Understanding the changes in the distribution and quantity of, and demand for, water resources in response to a changing climate is essential to planning for, and adapting to, future climatic conditions. In order to plan for future conditions and challenges, it is crucial that managers understand the limitations and uncertainties associated with the characterization of these changes when making management decisions. Changes in consumptive water use (water removed without return to a water resources system) will change streamflow, impacting downstream water users, their livelihoods, as well as aquatic ecosystems. Historical changes in available water may be attributed to changes in precipitation; but these changes...

Water is a key ecosystem service that provides life to vegetation, animals, and human communities. The distribution and flow of water on a landscape influences many ecological functions, such as the distribution and health of vegetation and soil development and function. However, the future of many important water resources remains uncertain. Reduced snowfall and snowpack, earlier spring runoff, increased winter streamflow and flooding, and decreased summer streamflow have all been identified as potential impacts to water resources due to climate change. These factors all influence the water balance in the Pacific Coastal Temperate Rainforest (PCTR). Ensuring healthy flow and availability of water resources is...
