  • Erosion control at a former nuclear testing site

    A reclaimed 175-acre section within the larger Rocky Flats National Wildlife Refuge in Jefferson County, Colorado, west of Denver, was home to a nuclear testing facility for 40 years. The area’s combination of rolling topography, high winds and incidents of heavy rain and snow increase the likelihood of soil erosion. Given the site’s past use, it’s important to keep soils ...

  • Modeling BMP’s in Sensitive Areas with xpswmm - King’s Beach Watershed Improvement Project - Case Study

    Introduction Located on the border of California and Nevada, Lake Tahoe (the Lake) is the largest alpine lake in North America. It is known for its scenic beauty and outstanding lake clarity. However, the clarity of the Lake has been declining since the mid-1960s because of the deposition of fine particles and nutrients from urban runoff and the growth of aquatic organisms that feed off the ...

  • Underwater Bridge Inspections – Drones Conducting Remote Evaluations

    Deep Trekker Remotely Operated Vehicles (ROV), or underwater drones, are establishing themselves as the ideal tool for underwater bridge inspections. It goes without saying that the structural integrity of a bridge is extremely important; after all, you’re only either walking, driving, or riding a train across it. With the public safety in mind and to continue the flow of traffic, these ...

  • River flow and sediment transport simulation based on a curvilinear and rectilinear grid modelling approach – a comparison study

    In the present work, a two-dimensional (2D) hydraulic model was used for the simulation of river flow and sediment transport in the downstream section of the Koiliaris River Basin in Crete, Greece, based on two different structured grids. Specifically, an important goal of the present study was the comparison of a curvilinear grid model with a rectilinear grid model. The MIKE 21C model has ...

  • A smartphone camera for the structure from motion reconstruction for measuring soil surface variations and soil loss due to erosion

    The suitability of a smartphone camera for the structure from motion (SfM) reconstruction for monitoring variations in soil surface characteristics and soil loss originated by a low intensity erosive event was evaluated. Terrestrial laser scanning (TLS) was used to validate the SfM model. Two surveys of the soil surface, one before and one after the rainfall event, were carried out for SfM and ...

  • Key Civil Construction Considerations for Oil and Gas Facilities

    Oil and gas facilities play a crucial role in our nation’s economy, provide fuel and electrical power, and create the ingredients for countless petroleum-based products. With such a vital role to play, it is essential that oil and gas facilities operate at maximum productivity and safety levels. While high quality maintenance, fabrication, and industrial services are all crucial for oil and ...

  • Areas Most Prone to Winter Storm Water Can Benefit from Temporary Erosion Control

    Winter can be a beautiful time of year. Generally, there are nice, brief storms and maybe some snow, and everything is fine. But occasionally, we get hit hard with storms that just won’t let up, such as when it rains for days or feet of snow come down—we are left to deal with the consequences. All too often, those consequences involve too much water, despite the work put into ...

  • USGS, NASA Study Finds Widespread Coastal Land Losses from Gulf Oil Spill

    A new USGS-NASA study found widespread shoreline loss along heavily oiled areas of Louisiana's coast after the 2010 BP Deepwater Horizon oil spill and compared the erosion from the spill with coastal changes Hurricane Isaac caused in 2012. A pattern of dramatic, widespread shoreline loss along Louisiana’s coast caused by the 2010 BP Deepwater Horizon oil spill has been ...

  • New Maps from Old Photos: Measuring Coastal Erosion

    U.S. Geological Survey scientists and their coauthors from the California Coastal Records Project have found a way to use historical aerial photographs not just to see evidence of coastal erosion, but to accurately measure how much has occurred over time. Applying a low-cost technique called “structure-from-motion” to five sets of oblique aerial photos spanning the years ...

  • Fort Carson Channel Repair - Case Study

    US Army Base chooses a more durable and easier to install solution than rip-rap for their channel repair project. Fort Carson, a 137,000-acre United States Army installation near Colorado Springs was established in 1942 following the events of Pearl Harbor. In 2016 the US Department of Defense noticed a huge gully forming along the roadway threatening its existence, requiring immediate ...

  • Sizing and Selecting the Proper Metering Pump: Part 1 of 2

    A typical agriculture or process application can consume large amounts of chemicals during daily operations. While the volumes may be large, though, they must also be very precise, with exact amounts delivered according to strict injection schedules. The pressures—from very high to very low—that the chemicals are injected at must also be governed precisely. This demand for ...

  • Quantitative pipe condition assessment with Pipe Penetrating Radar

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids ...

  • Flash flooding prediction in regions of northern Vietnam using the KINEROS2 model

    Flash flooding (FF) in Vietnam has become an important issue due to increasing loss of property and life. This paper investigates FF prediction using the Kinematic Run-off and Erosion model to perform comprehensive analyses to: (1) evaluate the role of initial soil moisture (θ) conditions using the Bridging Event and Continuous Hydrological model; (2) model the discharge (Q) using different ...

  • Numerical analysis of hydraulic jumps using OpenFOAM

    The present paper deals with a hydraulic jump study, characterization and numerical modeling. Hydraulic jumps constitute a common phenomenon in the hydraulics of open channels that increases the shear stress on streambeds, so promoting their erosion. A three-dimensional computational fluid dynamics model is proposed to analyze hydraulic jumps in horizontal smooth rectangular prismatic open-air ...

  • Remote sensing and GIS based assessment of soil erosion and soil loss risk around hill top surface mines situated in Saranda Forest, Jharkhand

    The quantitative analysis of soil erosion changes over 7 years due to mining operations in two neighboring hilltops in West-Singhbhum District, Jharkhand, are reported. CartoSat-1, ETM+ and LISS-IV satellites' data provided spatial inputs in Universal Soil Loss Equation (USLE) and Morgan, Morgan and Finney method (MMF) models, which were used to predict the average annual soil erosion during ...

  • Soil erosion in the riparian zone of the Three Gorges Reservoir, China

    The riparian zone of the Three Gorges Reservoir (TGR) has experienced substantial erosion that may severely deteriorate the reservoir ecosystem. To calculate soil erosion characteristics, field investigations have been conducted in the TGR area and 12 erosion-monitoring transects have been set in the middle TGR. The results showed that the dominating drive forces are water wave, gravity and ...

  • Implementing contour bank farming practices into the J2000 model to improve hydrological and erosion modelling in semi-arid Western Cape Province of South Africa

    Contour bank farming is a well-known agricultural management technique in areas which are characterised by intensive and erosive rainfalls. Contour banks are designed to reduce the flow velocity of overland flow and to intercept water before it concentrates in rills, thereby reducing the risk of soil erosion and land degradation. By their structure, contour banks noticeably impact surface runoff ...
