In-Plane Composite Drains
Drainage of water from outside basement walls, behind retaining walls, or highway cut or fill slopes, has long been a problem. A common solution is the aggregate drain. Often, installation...

Dredged Slurry Stabilization for Seagirt Marine Terminal
The Seagirt Marine Terminal is constructed on reclaimed land on dredged spoil from the I-95 Fort McHenry Tunnel in Baltimore, Maryland. Three stabilization procedures considered applicable...

Centrifugal Modeling of Phosphatic Clay Consolidation
As a by-product of beneficiation, quantities of dilute clay slurry are produced which are stored in retention ponds. One method of accelerating consolidation is to surcharge the clay with...

Steady-Site Dispersion of Pollutants in Rivers Near Sewage or Drainage Outfalls
A theoretical model is developed for determination of concentration distribution of pollutants in a river. Pollution is caused by the disposal followed by dispersion of sewage or drainage...

Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...

Valuable Design Insights Derived from Construction and Operation of Kinzua Dam
A number of design alternatives have surfaced during more than 17 years of operating experience at Kinzua Dam which should be useful in the design, construction, and operation of other...

Design Accuracy of Stormwater Detention Basins
While the stormwater detention basin is the most frequently used method for controlling runoff from developing areas in the United States, there appears to be no statement of the probable...

Evaluation of Two-Stage Outlet Hydraulics
A two-stage detention basin is an effective storm water management tool. This type of basin is designed to control two storm events and it will tend to perform better than a single-stage...

High Streamflow Behaviors in the Ohio River Basin
The intensity function, which describes the severity of the flood occurrences, is a critical factor in flood control and reservoir operation. It is found that the occurrence rates of high...

Hydraulics and Hydrology of Border Irrigation
Proper description of the hydraulics of irrigation of farmland is necessary in management. Many descriptions of furrow or border irrigation are not adequate to describe truly physically...

Realistic Hydrology for Basin Management
Several realistic yet simple methods to describe infiltration, soil moisture redistribution, aquifer recharge, canal seepage and stream-aquifer interaction in a river basin are presented...

Decreases in Runoff and Sediment Yield by Drainage
Runoff and sediment yield from three small agricultural watersheds were measured during four winter rainfall seasons. Following two rainfall seasons of data collection, a subsurface drainage...

Modeling Analysis for Management of Artificial Recharge
The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting...

River Basin Management: Role of Hydraulics and Hydrology
One of the major Illinois rivers originates in a neighboring state. The main stem of the river was channelized about 65 years ago, and is considered to be a 'drainage ditch....

Development of the Rio De La Plata Hydrographic Basin
The rivers and climate of the basin are described. Available and developed hydropower sites are presented. The international consequences of various water management schemes are discussed....

Goals and Objectives in Design of Detention Outlets
Goals are the broad general purposes of the detention pond and its outlet works. A typical goal for a detention pond would be to help manage storm runoff so as to maintain historic conditions...

New Wastewater Process Cuts Plant Costs 60%
By combining the aerator and the clarifier into one basin, this new wastewater treatment process can slash capital costs up to 60% and operating and maintenance costs up to 45%. Raw sewage...

Ditch Flow Program
Seventeenth in the CE Computing BASICS series, the program in this article is for simplifying drainage calculations. The program will provide critical and normal velocities, depths and...

Advances in Irrigation and Drainage
Surviving External Pressures
This collection of papers, presented at the 1983 ASCE Irrigation and Drainage Specialty Conference held in Jackson, Wyoming, July 20-22, 1983, cover a variety of topics related to irrigation...

Urban Hydrology Progress Since 1979 in Australia
This report highlights urban hydrological activity in Australia in the period 1979-1983, since the earlier reports by Aitken (1976) and Aitken and Laurenson (1979). The high level of interest...
