Recent Work in Fish Passage
In an effort to continue identifying potential solutions for moving juvenile fish downstream past dams, the US Department of Interior's Bureau of Reclamation granted research awards as part of a prize competition.
Online portal now available for water quality assessment worldwide
In support of the International Initiative on Water Quality (IIWQ) of UNESCO’s International Hydrological Programme, EOMAP GmbH & Co. KG has helped create the IIWQ World Water Quality Portal.
Knowledge is Power
Looking ahead at the future of hydropower and a cooperative approach, this article studies the work completed on the Roanoke River. HydroWorld December 2017.
Niagara River’s islands are teeming with life again
Not long ago, bald eagles in Buffalo only appeared on postage stamps, and the blue heron was just a popular music festival. Then came restoration work along the Niagara River.
Hydrologic Modeling of Large Drainage Basins – Unique Challenges and Solutions
Modeling extreme floods in large area drainage basins can present unique challenges that are not typically of concern within smaller drainage areas. A case study of a recent hydrologic modeling effort that was performed for the Susquehanna River drainage basin will be presented.
Renovating Aging Penstocks: Analyzing Replacement Alternatives for Cost and Energy Generation
The Bulls Bridge hydroelectric development, located in the towns of Kent and New Milford in Litchfield County, Connecticut and currently owned by FirstLight Power Resources (FLPR), is one of five hydropower developments forming the Housatonic River Hydroelectric Project.
Evaluating the Spillway Capacity of the Morning Glory Spillway at Harriman Dam
Harriman Dam is a 217.5 foot high earthen hydropower dam which was built in 1924 and has since been raised three times. Excess inflows to the dam are discharged through a morning glory spillway with an outside diameter of approximately 160 feet transitioning into a 22.5 foot diameter drop shaft and discharge tunnel.
Visualizing and Analyzing ADCP and CFD Data Using Python and Other Open Source Tools
An Acoustic Doppler Current Profiler (ADCP) can be linked with a Global Positioning System (GPS) to collect spatially-referenced bathymetric and three-dimensional velocity profile datasets.
Varying Bathymetric Data Collection Methods and their Impact on Impoundment Volume and Sediment Load Calculations
Two bathymetric datasets and various subsets for Conowingo Pond on the Lower Susquehanna River were analyzed and compared to explore the potential effects of four survey designs on impoundment volume and sediment load estimates.
Quantifying the Impact of Hydropower Operations on Shoreline Erosion throughout the Turners Falls Impoundment (Connecticut River)
The Northfield Mountain Pumped Storage Project (Northfield Mountain) (FERC No. 2485) and the Turners Falls Hydroelectric Project (Turners Falls) (FERC No. 1889), collectively referred to as the Project, are located on the Connecticut River in the towns of Montague and Erving, MA, respectively.
The Relationship Between Patterns in Flying Adult Insect Assemblages and Vegetation Structure in Wetlands of Ohio and Texas
The success of compensatory wetland replacement is frequently judged on the basis of percent vegetation cover. Measuring percent cover of wetland species, or the survival of planted species, especially only one or two years after construction seems tautological.
Vegetation of Drew Woods, and Old-Growth Remnant in Western Ohio, and Issues of Preservation
Over the two decades since the first state natural heritage programs were established in the Midwest, many preserves have been dedicated to help ensure the persistence of species, communities, and geological features that human activities have increasingly placed in jeopardy.
A Modified Point-Centered Quarter Sampling Technique: A Tool for Plant Community Classification and Evaluation
The Ohio Natural Heritage program has used a modified point-centered quarter sampling method to gather data on the structure and composition of forested plant communities in the state. During 1987 field season, the performance of this method was tested.
Leaf Litter Redistribution Among Forest Patches Within an Allegheny Plateau Watershed
This study quantified the redistribution of leaf litter in and among distinct patches within Neotoma Valley, a 73 ha watershed in the unglaciated Allegheny Plateau of Ohio. Total vertical litterfall and Quercus litterfall were greater on the Quercus dominated east slope and valley bottom than on the west slope or on the ridgetops.
Localized Ice Storm Damage in an Appalachian Plateau Watershed
During 19-20 January 1986 a storm deposited up to 3 cm of glaze ice on trees in lower slope and valley bottom positions in Neotoma Valley, an unglaciated 72-ha forested watershed in S-central Ohio.
