  • Weather SDM: estimating snow density with high precision using snow depth and local climate

    Snow density is an important measure in hydrology used to convert snow depth to the snow water equivalent (SWE). A model developed by Sturm, Tara and Liston predicts the snow density by using snow depth, the snow age and a snow class defined by the location. In this work this model is extended to include location and seasonal weather-specific variables. The model is named Weather Snow Density ...

  • New from Lufft: The laser-based snow depth sensor SHM31

    In future, one of our new products will support weather services, road operators, operators of winter sport areas and energy producers in the field of environmental monitoring: The SHM31 is able to deliver snow depths of up to 15 meters. It represents an advancement of the SHM30, which came onto the market in mid-2009. New snow height sensor SHM31 compared to its predecessor SHM30 ...

  • Analysis and modelling of snow bulk density in the Tyrolean Alps

    An extensive collection of in-situ snow measurements is used to characterize snow conditions in the entire elevation range of the alpine area of Tyrol, Austria. Regularly observed snow station data are evaluated with respect to mean snow density–time curves of the period 1952–2010. Dependent on the observed snow depth (HS), the snow bulk density (ρ) is ...

  • Groundwater recharge during spring thaw in the Prairie Pothole Region of North America

    Snowmelt governs recharge in the Prairie Pothole Region of North America, but little is known about the soil at the time of recharge. Depth of snow, surface water, water table, and frozen soil were measured within a 2-ha landscape depression in Minnesota during spring thaw in 2000 and 2001. The water table rose by at least 1 m within 24 h after a pond formed within the landscape depression as a ...

  • A novel freeze protection strategy for shallow buried sewer pipes: temperature modelling and field investigation

    The burial of sewer and water pipes below the maximum ground frost depth can be very costly and laborious in regions with cold winters. If a freeze protection measure is applied, the utility lines can be installed in a shallower trench to reduce the excavation needs. One freeze protection measure, so called heat tracing, consists of supplying heat along the pipes. In this work, the use of 4th ...

  • Snowcover and melt characteristics of upland/lowland terrain: Polar Bear Pass, Bathurst Island, Nunavut, Canada

    The seasonal snowcover and snowmelt (2008–2010) of an extensive low-gradient wetland at Polar Bear Pass, Bathurst Island, Nunavut, Canada (75°40′ N, 98°30′ W) was examined. This wildlife sanctuary is characterized by two large lakes and numerous tundra ponds, and is bordered by rolling hills with incised hillslope stream valleys. In arctic environments snow ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Using the HydraProbe Soil Sensor for Determination of Flood Risk in the New York State Mesonet

    New York's Mesonet uses the HydraProbe and other meteorological sensors to help forecast flood hazards and climate. In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at ...

  • Triad expedites brownfields redevelopment in Fairbanks

    The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...

  • Developing a typical rainfall period to analyze CSOs in San Francisco

    The City of San Francisco has used InfoWorks CS as the basis for developing a continuous long-term (five year) rainfall period, which is being used to evaluate sewer flows in a collection system model. Ultimately, the City aims to develop a 30-year plan for its combined sewer and wastewater treatment system, a major cornerstone of which is the creation and application of a detailed hydraulic ...

  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • Stormwater Best Management Practices (BMP)

    Storm water is the result of rain or snow melt that collects in an area that can drain from into a nearby body of waters such as a lake or river. The water can collect on roof tops, parking lots, saturated ground, roads, etc. The problem is that many of the pollutants of our modern living such as oil, grease, pesticides, sediment, salt, and animal waste are washed away within the storm water and ...
