Shape of Storm Pollutograph from the Four Different Rural Watersheds
(Abstract only) Just as a hydrograph describes the flow rate of water for a storm event, a pollutograph shows the rate at which pollutants dissolved or suspended in the runoff are transported....

Probabilistic Simplified and Detailed Subsurface Drainage Water Quality Modeling of Nitrate Leaching
A transparent uncertainty structure is derived for simplified and detailed conceptual nitrate leaching as a result of a probabilistic modelling procedure. The uncertainty structure consists...

Using Tracer Response Curves to Quantify Hydraulic and Channel Complexity of Prairie Creek, Northwestern California: Implications for Over Wintering Habitat for Juvenile Coho Salmon
This study measured and compared aspects of channel structural complexity with hydraulic complexity at a range of flows including winter storm flows. Five 200-meter reaches containing...

Investigation of Flood Protection from Alluvial Fan Flows and Minimizing Impacts to a Sensitive Habitat Preserve: Whitewater River Basin, Coachella Valley, California
The study describes and evaluates (1) the baseline conditions to hydrology, hydraulics, wind transport of sand, sediment transport by fluvial process, the environment, economics, and (2)...

Spatial Decision Support System for River Basin Management
MODSIM is a generalized river basin network flow model designed to simultaneously assure that water resources are allocated according to physical, hydrogeological, and institutional/administrative...

Rediscovering the Lost City
Since 1994, Kenneth R. Wright, P.E., of Wright Water Engineers, in Denver, has been studying evidence of civil engineering at the ruins of Machu Picchu—an ancient Inca city in the Andes...

Subsurface Information for Construction Contracts - Impacts on the Geoprofessional Community

Safety in a Designer's Hands
Although contractors face safety issues every day, engineers and architects have traditionally not addressed construction site safety in project designs. But there are design practices...

Beach Town Cleanup
The Avila Beach remediation project in California required the demolition of numerous structures and part of the beach in order to remove more than 200,000 cu yd (153,000 m³) of contaminated...

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...

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...
