The Tidal Inlet Characteristics of a Small California Estuary
The inlet channel of the Russian River estuary in Northern California is subject to frequent closure. The formation of a barrier beach across the inlet channel creates ponding of the river...
Wetland Restoration in the Dutch Dune Area
Interference by man has affected the natural Dutch dune area seriously. The harmful effects of drinking water supply activities include low groundwater tables in the valleys, unnatural...
A Hydrodynamic Model for a Tidal Wetland
A hydrodynamic model is developed for San Elijo Lagoon, a wetland with tidally influenced area of 1.5 km2 (380 acres). A quasi two-dimensional (2-D)...
Mechanics of Riprap Movement in Tidal Flow
This analysis emphasizes the need to obtain data on the size and shape of riprap pieces as a function of movement, data which are surprisingly difficult to obtain from published studies....
Annual Oscillation of Mean Monthly Water Levels at U.S. Ports
The annual variation in water level is not widely recognized among engineers. It could effect the selection of design ship channel depth or marina channel dredging, and tidal wetland creation...
Comparison of Two Methods of Screening Bridges for Scour
Scour evaluations were performed for large numbers of bridges in two separate studies in New York and New Jersey. The two studies used different screening methods for identifying high-priority...
Case Studies of Bridge Scour in Western New York
As part of the New York State Thruway Authority's bridge hydrologic/hydraulic evaluation program, 63 structures over 42 stream crossings in western New York were assessed for scour potential...
Scour Analysis for Bridges over Missouri and Mississippi Rivers
Engineering services are being provided for three bridge crossings, two over the Missouri River and the other over the Mississippi River. Scour consideration for the bridged waterways...
Risk Analysis of River Bridge Failure
The proposed procedure to determine the risk of river bridge failure is based on observations and analysis of river bridge failure data of more than 300 U.S. bridges, 180 South African...
