The Influence of Hillslope Shape on Debris-Flow Initiation

Newport News: Brackish Water Gets Fresh
Rapid growth was straining freshwater supplies in Newport News, Virginia. Studies showed Newport News Waterworks that they could be facing a 30 mgd deficit by 2040 and ran a 50% chance...

The Evolution of Geosynthetics
Although the geosynthetics industry only began in the 1960s, it roots can be traced to the earliest humans. Soil stabilization, soil reinforcement, liquid drainage and leak proof barrier...

Construction of Permeable Bases for Airfield Pavements

Remediation of a Contaminated Thin Aquifer by Horizontal Wells

Prefabricated Vertical Drains Zone of Influence Under Vacuum in Clayey Soil

Making a Map of Public Health Hazards
Accurately deducing the long-term exposure of community members to health hazards has always been a challenge for engineers. In 1993, the town of Somers, Conn., discovered a residential...

Financing the Future of Storm Water
For Sarasota County, Fla., draining storm water no longer means draining municipal funds. By establishing a modern storm-water utility, the county has provided a dedicated funding source...

A New Direction in Remediation
Engineers have always had to rely on wells for onsite soil and ground water remediation systems. During the past several years, horizontal drilling technology, adapted from oil recovery...

Reliability of a Box Culvert Structure under a Levee during Project Floods

Biological Clogging and Rehabilitation of Drains and Well Systems and the Implications on Groundwater Quality

A Multiperiod Approach for the Solution of Groundwater Management Problems using the Outer Approximation Method
In a previous work the Outer Approximation method was presented (Karatzas and Pinder, 1993 and 1996) for the solution of groundwater management problems where the selected pumping rates...

An Evaluation of Drainage Conditions in the San Joaquin Valley
The discovery of deformities and deaths of aquatic birds at Kesterson Reservoir in 1983 substantially altered the perception of agricultural subsurface drainage water threats in the San...

Alternatives for Managing Shallow Ground Water in Arid Irrigated Areas
The combined operation of a drainage system for subirrigation and drainage is being considered for application in arid areas of the world. This is accomplished by modifying an irrigation...

Dormant Season Alfalfa Water Balance on the NIIP
Non-growing season water balance parameters were measured for alfalfa under high-elevation desert conditions of the Navajo Indian Irrigation Project in northwest New Mexico. The lysimeters...

The 1995 Floods of Rhine and Meuse - How Predictable are Water Levels in the Netherlands

Statistical Distributions and Natural Hydrograph
For design projects in the water resources area, a hydrograph is commonly used to determine the flood volume generated by a given drainage basin. The division of total flow into direct...

Southern San Joaquin Drainage Water Management
This paper addresses management of subsurface saline drainage water in a closed basin in the Southern San Joaquin Valley. A large number of ponds have been constructed to evaporate saline...

Drainage Ponds and Demonstration Wetlands
In California's southern San Joaquin Valley, subsurface irrigation drainage pumped into shallow evaporation ponds often contains elevated concentrations of selenium. The selenium...

Economic Incentives Encourage Improvements In Farm-Level Water Management Practices
The Broadview Water District has implemented economic incentive programs in recent years to encourage improvements in irrigation practices to reduce the volume of subsurface drain water...
