Trace Metal Distribution in the Sediments of the Bight of Bonny, South Eastern Nigeria
Coastal sediments are important hosts for pollutant trace metals. The concentration and distributions of heavy metals depend on factors such as grain size of sediments, availability and...

Evolution and Dynamics of the Chilka Lake
The Chilka Lake, the largest coastal lagoon in Asia, has occupied a possible tectonic depression along the east coast of India. Although the open sea coast was along the western margin...

A Study on Local Residents' Evaluation of Residential Waterfront Area
In the present study, a questionnaire survey was conducted in 9 cities in Japan to investigate the utilization perception and utilization of local residents to neighborhood waterfront...

AVL's Future Holds Little Value without Integrated Data Communications for Total Mobile Resource Management
The future of automatic vehicle location (AVL) lies in broadening its definition for greater market acceptance and applicability. AVL by itself is for limited utility. To solve real-world...

Lag Relations for Semi-Arid Regions and Urban Areas
The use of synthetic unit hydrographs often requires the estimation of lag or other travel time parameters. Several procedures are available for estimating such unit hydrograph parameters....

Flood Assessment at a Low-Level Radioactive Waste Site in Southern Nevada
Flood hazard analysis on alluvial fans using Federal Emergency Management Agency (FEMA) methodology is not limited to the FEMA Alluvial Fan Methodology (AFM). Other FEMA-accepted methods...

Nonpoint Source Pollution Model for Agricultural and Rural Watersheds
A dynamic hydrologic and nonpoint source pollution simulation model for agricultural and rural watersheds; capable of simulating rainfall-runoff, soil erosion, sediment transport, mixing...

Urban Nonpoint Pollution Control Kettering Demonstration Project
The development of effective nonpoint pollution control programs has become one of the most complex challenges facing local and state authorities. Because of the multifarious nature of...

Irrigation, Agrichemicals and the Environmental Impact, the Role of Hydrologic Non-Point Source Models
The importance of pollution loads from agricultural lands and the degradation of soils and water resources has brought about extensive efforts throughout the environmental and agricultural...

Development of a Raw Water Master Plan Model to Assist Long Range Drought and Water Conservation Planning for the City of Louisville, Colorado
The City of Louisville, a municipal corporation charged with meeting the water demands of almost 5,000 water accounts and faced with a diminishing supply of available senior water rights...

Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...

An Integrated Software System for 3DFEMWATER: A 3D Grid Generator, A Graphical Post-Processor, and Additional Analysis Tools
An integrated software system for 3DFEMWATER has been developed to improve the groundwater flow modeling process. The system generates finite-element grids, graphically portrays simulation...

Application of Vadose Zone Flow and Transport Models
This paper summarizes application of two subsurface flow and transport models at Superfund sites, and evaluation of a number of other unsaturated zone models. The screening level models...

Design and Analysis of an Irrigation Pond Using Urban Stormwater Runoff
Stormwater held in detention ponds can be reused for irrigation. A simulation of a mass balance on pond storage volume using rainfall and evaporation data for selected areas is presented...

Flow and Transport of Nonaqueous Phase Liquids in Groundwater Systems
Nonaqueous phase liquids (NAPLs) are present at numerous hazardous waste sites and are suspected to exist at many more. Due to the numerous variables influencing NAPL transport and fate...
