Methods and Applications of Numerical Hydrology on a Drainage Basin
A model is presented here (MOMID) to study, having considered a morphological base of the drainage basin, the unit hydrogram and the routing time along the basin itself....

Channel Entrenchment Along the Post Creek Cutoff in Southern Illinois
The Post Creek Cutoff was constructed in 1915 by the Cache River Drainage Commission to divert flow from the Upper Cache River to the Ohio River. The construction of the cutoff reduced...

Land Drainage and Estuarine Salinity Response
An investigation is being conducted to (1) quantify the short-term effects of freshwater agricultural drainage on salinity in a tidal creek and (2) evaluate the off-site effects of water-control...

Relief of an Urban Storm Drainage System
The Peaks Branch storm sewer system was designed in the 1930s to drain 5.7 square miles of East Dallas. Subsequently, development blocked the emergency overflow paths and many areas are...

Daily rainfall records during the months of October through April at rainfall gaging stations near the Kings River drainage basin in the Sierra Nevada Mountains of central California were...

Special Hydraulic Problems Related to Coastal Louisiana Drainage Systems
The urbanized coastal areas of southeast Louisiana present unique problems for hydraulic engineers. These problems relate to the design of drainage systems serving leveed areas with flat...

A Synthetic Simulation Model of Storm Surge History and Inland Drainage in Coastal Zone Areas
In this paper, a synthetic storm surge model is proposed. With the input information of peak surge height, storm duration, and shape coefficients, this model is capable of simulating most...

Drainage Problems in a Highly-Developed Shoreline Area
Hilton Head Island, South Carolina, is a 42-square mile barrier island on the south-east coast Flooding of roads and properties is a continual problem in this low-lying, flat area due...

A Rational Approach to Selecting an Optimal Design Storm for Flood Control
A rational methodology is presented herein for determining the optimal design storm frequency when planning for flood protection in new urban areas. The technique was developed from an...

Elements of a Coastal Stormwater Drainage System
Several elements in the design of a stormwater drainage system that outfalls to the ocean are discussed. The paper discusses a study conducted of the Ocean Lakes Watershed near Myrtle...

Uplift Pressures in Existing Concrete Dams
This paper is a brief summary of a report of the same title prepared for the Electric Power Research Institute (EPRI) as part of its program to study ways to economically improve dam safety....
