The DOD Groundwater Modeling System: A Conceptual Model Approach
A suite of new simulation tools have been developed in the version 2.0 of the Department of Defense Groundwater Modeling System (GMS). These add considerable complexity to the GMS which...

European Progress on river Renaturalisation
Most restoration projects in Europe have been designed to maximise species richness with little regard for channel stability. To recreate a sustainable natural channel it is necessary...

Ecological and Biological Considerations in River Restoration
When planning river restoration projects, proper consideration must be given to the target resources of concern. This should include provisions to meet the physical, hydraulic, and biological...

Role of Vegetation in Hydraulics of Channel Restoration
Boundary layer theory is used to develop a backwater model for flows through vegetated waterways which can be employed to approximately estimate flow depth variation in channel restoration...

River Meander Zones and Floodplain Reconnection
A natural disturbance regime concept is described for understanding ecosystem changes due to human activities. Re-establishment of river meander zones is proposed as an application of...

Storm Water General Industrial Permit Non-Filers Identification and Outreach
Storm water discharges convey pollutants from urban activities that can impair surface water quality. Industrial facilities have been identified as one source of storm water pollutants...

A California Handbook for Developing an Industrial/Commercial Storm Water Inspection Program
Runoff and non-storm water discharges to storm drains from industrial and commercial businesses can be major causes of storm water pollution in urban areas, but there are sources of this...

Coping with EPA's Storm Water Permit for Hazardous Waste Facilities, Industrial Landfills, Wastewater Treatment Plants, and Recyclers
The Environmental Protection Agency (EPA) has released NPDES storm water monitoring data from group applicants. This paper will analyze that data to determine which pollutants are present...

Dredging in the Southern Sacramento-San Joaquin Delta
The California Department of Water Resources and the United States Bureau of Reclamation are jointly conducting an environmental study and are proposing to release a draft Environmental...

Water Quality Impacts of Dredging and Disposal Operations in Boston Harbor
The Massachusetts Port Authority is presently planning a navigation improvement project in the port of Boston, consisting of dredging the 10.7 m (35 ft) deep channels and berths in the...

Best Management Practices and Community Education
The 1987 Water Quality Act requires the permitting of municipal separate storm sewer systems and the reduction by permittees of the discharge of pollutants in stormwater to the maximum...

Anaheim State-of-the-Art Water Treatment Plant?Six Years from Conception to Completion
After six years of intensive planning, budgeting, pilot testing, design, and construction, the City of Anaheim, California, has successfully completed the modifications to the 15 mgd Lenain...

Use of Reclaimed Water in Cooling Towers

Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things?wise water planning...

ASR Case Study?City of Salem, Oregon
The City of Salem, Oregon is developing an Aquifer Storage and Recovery (ASR) system to provide a 20 mgd capacity, 440 mg volume, emergency storage and peak day supplementary supply. When...

Water Conservation for Boilers and Steam Systems
The City of Anaheim Public Utilities Department conducted a comprehensive water use survey for Coca-Cola Foods plant located in Anaheim and recommended several conservation measures to...

Subcatchment Parameterization for Runoff Modeling Using Digital Elevation Models
Numerical algorithms are presented to estimate the length, width and slope of rectangular planes representing irregularly shaped overland contributing areas defined on raster Digital Elevation...

A DEM Based Hydrologic and Sediment Transport Model
