An Overview of Factors Affecting Land Application of Food Processing Wastes
The food processing industry can use slow rate, rapid infiltration or overland flow systems. Slow rate systems are the most common method used for land application. The limiting design...

Estimation of Mean Water Depth for Border Irrigation
The mean water depth for border irrigation is derived, using dam-break simple wave solution and boundary layer theory, as a function of inflow discharge, bottom slope, bottom roughness,...

Evaluation of Basin-Furrow Irrigation Systems
The division of the total flow into basin-furrows is analyzed using both energy and momentum principles. A zero-inertia model is applied to simulate the advance phase using different infiltration...

Runoff Model for Watersheds of Nonhomogeneous Characteristics
A watershed of any configuration, topography, and spatial distribution of cover, soil and channel characteristics is described as a plannar grid. Time-varying precipitation is applied...

Furrow Modeling with Variable Hydraulic Characteristics
A zero inertia furrow irrigation model was developed to run on an IBM-compatible micro-computer. The depth gradient term of the momentum equation is approximated by averaging over the...

Effect of Rainfall Intensity Distribution on Excess Precipitation
The effect of the time distribution of rainfall intensity on the prediction of the depth of excess precipitation is evaluated. A comparison is made of the excess precipitation produced...

Guidelines for I/I Analyses and SSES Studies

Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...

Groundwater Migration Impact on Sewer Rehabilitation

Field Permeability Test for Earthen Liners
A sealed double-ring infiltrometer (SDRI) was developed for in-situ measurements of the hydraulic conductivity of earthen liners and covers. The characteristic of the SDRI that distinguishes...

Evaluation of PCP/Oil Spill on CFT Indian Reservation Near Nespelem, Washington
This paper presents the immediate action taken, the field work performed, and the engineering analysis performed in response to a spillage of a solution of pentachlorophenol (PCP) and...

Infiltration as a Stormwater Management Component
This paper discusses the implementation of infiltration practices in Maryland. The benefits of infiltration are briefly discussed along with the regulatory background. Standards and Specifications...

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...

Santa Barbara Hydrograph with Green-Ampt Infiltration
Numerous models are available to estimate rainfall-induced runoff from watersheds. The leading criteria in model selection is often reproducibility. Models that are reproducible are often...

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...

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...

Estimating Transmission Losses
Infiltration or transmission losses in ephemeral stream channels are an important part of the water balance in arid and semiarid regions. The governing equations for movement of flood...

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...
