Protecting the Source
The city of New York is engaged in a five-year, $1.5 billion effort to protect water quality in the upstate watersheds that are the source of its drinking water. Under the terms of a 1997...
Irrigation Method Selection Process
Intelligent selection of the irrigation method that best meets the goals and objectives of an irrigated agricultural development is of primary importance in the design process. A system...
Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...
Sprinkler Irrigation
In sprinkler irrigation, water is applied to the soil using a pressurized piping system with nozzles, jets, or perforated pipe that sprays the water into the air. These sprinkler devices...
Subirrigation: Water Table Management
Water table management (subirrigation) is accomplished by controlling the water table, usually through a subsurface drainage system. The crop is subirrigated with water being furnished...
Scour Monitoring at Johns Pass and Nassau Sound, Florida
Scour monitoring instruments were installed on two bridges spanning tidal inlets in Florida as part of a research project to develop scour instrumentation. Previous prototype installations...
Applicability of Scour Equations in Tidal Areas
Bridge scour and waterway instability in the coastal region where waterways are subjected to tidal flow can be subjected to mass density stratification, water salinity, sedimentation...
Equalizing Wet Weather Flows
Sanitary sewer overflows and combined sewer overflows can wreak havoc on communities by flooding basements, contaminating drinking water sources and recreational water bodies, and flowing...
Banking on Bioengineering
Geoenvironmental engineers have traditionally used riprap to protect streambanks and river banks from erosion. In recent years, however, river regulators, permitting agencies, and county...
Wetlands Treat Mine Runoff
Engineers were asked to design a treatment system for the severely acidic drainage from the Mike Horse and Anaconda metals mines in Montana. Challenges included the mountainous terrain,...
