Selection of the Form of Calculated Flood Hydrograph in Projecting Water Release Facilities
Traditionally, in evaluating hydraulic structures, river flood runoff hydrographs are determined by maximum flood water volume and discharge, duration of the flood and some other parameters,...

The Part of Precipitation in Some Ecological Problems of the Dnister Basin
The purpose of the present paper is to study the peculiarity of precipitation falling in the Dnister basin, their distribution on territory, and research of several year's precipitation...

Application of an Optical Monitor in Automatic Control of Coagulation Dosing in Water Treatment Operations
The feasibility of applying an optical monitor in the automatic control of coagulation was assessed in this study. Prior to simulation testing, a series of batch tests was performed to...

Design and Implementation of On-Farm Surface Drainage Projects in the Humid Tropics of Mexico
In the humid tropics of southeastern Mexico, the Mexican National Water Commission (CNA) has constructed a network of collector drains for stormwater runoff removal. At the same time the...

A New Strategic Management of Pumping Station in Sewer Systems
Pumping stations are literally the heart of most sewer system operations and sewage treatment plant processes. Current studies show that a small improvement of pump efficiency will offer...

Impact of Point and Nonpoint Discharges on the Water Quality of a Reach of the Red River of the North
Projected increase of discharge of point and nonpoint-source effluents into rivers, make compliance with water quality standards increasingly difficult and necessitate controlling these...

CHEMFLO Modeling of Aquifer Bioremediation in Vadose Zone
This paper deals with bioremediation in the vadose zone with an emphasis on using numerical models as a tool to ensure that the concentration of nutrients is maintained at a required level....

COASTMAP: An Integrated System for Environmental Monitoring, Modeling and Management
The development of COASTMAP, an integrated system for environmental monitoring, modeling and management for fresh and marine waters, is presented. The system allows the user to collect,...

Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...

The 1995 Flood in Southeastern Norway?Operational Forecasting, Warning, and Monitoring of a 200-Year Flood
The southeastern part of Norway experienced during the 1995 spring the highest flood recorded since the devastating flood in July 1789. The snow storage was at the end of April 30 to 50...

The Largest Water Reservoirs of Russia in Flood Control
(Asbtract only) The largest water reservoirs of Russia, such as a reservoirs cascade on Volga and Kama Rivers, are used for solution of a number of water problems including flood control....

Detailed Measurements of Scour at Bridges
The U.S. Geological Survey, in cooperation with the Federal Highway Administration, has recently developed equipment and techniques for collecting detailed bathymetric and hydraulic data...

Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...

Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...

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...

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...

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...

Developing Parameters for a Quasi-Distributed Runoff Model Using GIS
The widespread availability of radar precipitation data is driving rainfall-runoff modeling from lumped-input to distributed-input methods. As a consequence, model parameterization is...
