Cover Allocation in Rangeland Watershed Management (A Review)
The importance of cover on rangelands has been recognized for many years. This paper reviews the importance of cover in terms of infiltration and erosion and provides management recommendations...
Snow Management Practices for Increasing Soil Water Reserves in Frozen Prairie Soils
It is demonstrated that stubble management practices can be used to increase snowcover accumulations in the Canadian Prairies. However, the potential for significant increasing soil water...
Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...
Analysis of Unsaturated Flow Beneath a Landfill
Using the linearized theory of flow in unsaturated porous media, a mathematical model was developed to study the distribution and extent of unsaturated flow from a source of infiltration...
Hydrograph Decomposition: Using a Technical Database
Trouble shooting for infiltration/inflow (I/I) problems in a sewer system is made much easier with the aid of a computerized hydrograph decomposition methodology. A methodology has been...
Los Angeles Infiltration/Inflow Reduction Program
The City of Los Angeles maintains and operates two wastewater collection and treatment systems: the Hyperion System and the Terminal Island System. During the wet months of December through...
Effect of Surge Cycle Ratio and Cycle Time on Infiltration
A recirculating furrow infiltrometer was used to simulate surge flow irrigation for various cycle times and cycle ratios. The data collected was used to evaluate two empirical surge flow...
Effect of Wetted Perimeter on Infiltration in Furrows
Five empirical infiltration equations were evaluated using data from blocked infiltrometer tests with wetted perimeter values ranging from 28 to 49 cm. The results indicate that the Kostiakov...
Modeling Flow in an Ephemeral Stream Channel
A particularly distinguishing characteristic of ephemeral streamflow is the large role played by infiltration. Infiltration interacts in a complex way with channel flow to control the...
The Evolution of Jointing Vitrified Clay Pipe
Advances made in the jointing of vitrified clay pipe during the last half century, illustrate the concern of the clay pipe industry to provide top quality jointing methods. Early 19th...
Predicting Overland Flow and Infiltration
The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply...
An Infiltration Based Runoff Model For Use With a Design Store
The feasibility of using an infiltration approach for routine runoff prediction has become a reality with the development of approximate infiltration models based on physical principles...
Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
Design of Rapid Infiltration Systems
Effects of Infiltration on Runoff Hydrograph
An Infiltration Model for Surge Furrow Irrigation
Flood Travel Time
The effects of infiltration on the flood travel time are investigated. In flood prediction, the physical domain for flood cumulation is expressed by the period of time for water to travel...
Sewers: Repairing Beats Replacing
Rehabilitating decaying sewers can be up to 70% less costly than replacing them. Yet most sewerage agencies wait until a pipe collapses before taking action, necessitating expensive emergency...
