Treatment, Reuse and Disposal of Drain Waters
Treatment, reuse and disposal options of agricultural drainage water present formidable technical problems. Various treatment technologies and disposal methods have been studied. Reuse...
Prognosis on Managing Trace Elements
Management options assessed for trace elements discharged from irrigated lands include source control, drainwater reuse, drainwater treatment and removal of contaminants, disposal, and...
Location, Design, and Construction of Water Wells
Proper location, design, and construction of water wells are important to assure their efficient operation and minimize maintenance problems. Detailed and accurate records of the design...
Efficiency Testing of Water Wells
In the operation of a water well, the difference between the water level in the well before pumping starts and after it has been pumping for a period of time is termed 'drawdown.'...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
Nonpoint Source Pollution from Agricultural Drainage: Impacts and Innovations in California
This paper provides an overview of the more significant impacts of agricultural drainage in California, and describes the role of the State's Agricultural Drainage Water Management...
Potential Sediment Yield From a Burned Drainage - An Example From the Wasatch Front, Utah
Two debris flows hit Mapleton City, Utah, as a result of rainstorms on a steep drainage basin, which had recently been burned. Debris flow potential for the area was evaluated to determine...
Deadly Debris Flows on I-5 Near Grapevine, CA
A series of debris flows inundated the southbound lanes of interstate Highway 5 (1-5) approximately 110 km (70 mi) NW of Los Angeles, California, between Fort Tejon and Grapevine, early...
Evolution of Drainage Criteria, Albuquerque, New Mexico
Storm drainage in Albuquerque, NM is a central issue in land development. To expedite municipal development while assuring public safety and preserving environmental attributes in a public...
Drainage Manual for Clark County, Nevada
The development of a flood control district and its associated capital improvement and regulatory programs does not by itself address drainage standards for a community. While the capital...
Phoenix Flood Hydrology for Price Expressway
Recently HDR Engineering, Inc. (HDR) completed a study of the off-site stormwater volumes and peak flow rates for the Price Expressway and Santan Freeway in suburban Phoenix. HDR is the...
Regional Flood-Frequency Relations for Streams with Many Years of No Flow
In the southwestern United States, flood-frequency relations for streams that drain small arid basins are difficult to estimate, largely because of the extreme temporal and spatial variability...
Design Storms and Sizing of Flood Control Facilities
Design stroms which embody the rainfall characteristics of an area are used for the sizing of drainage facilities. The selection of a design strom may significantly influence the design...
A Fractal Concept in Stream, Swale, and Sheet Flow
The concept of fractals, in simple terms, says that the patterns of natural features repeat themselves as the feature gets divided into successively smaller segments. In this paper, the...
Weibull Distribution and Natural Hydrograph
For design projects in water resources, a hydrograph is commonly used for the determination of flood volume generated by a given drainage basin. The division of total flow into direct...
Study on Hydrologic Response Via Channel Network Geomorphology
A drainage basin consists of slopes and channels. Slopes are the main fields at which rainfall input is converted into discharge. Stream-channels are the main fields at which the discharge...
Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...
Irrigation and Drainage
This proceedings consists of 70 papers presented at the National Conference on Irrigation and Drainage sponsored by the Irrigation and Drainage Division of the American Society of Civil...
Commuting Computing
Portable computers come in many different shapes and sizes and boast many of the same features as desktop machines. Unlike desktop PCs, however, the key to getting the most use out of...
Rehabilitating West Point's Tunnel
Conrail, the Northeast's largest freight railway, had a problem with a tunnel carrying the fastest freight line between the New York area and the Pacific. The 1882 tunnel...
