Infiltration and Overland Flow: Coupled Vs. Uncoupled Modelling

Radon Entry & Control Versus Indoor Dynamics
The measurements of air infiltration, interzonal transport and exfiltration as the diagnostic procedures have been significantly influential in the selection, implementation and evaluation...

Pressure Differences Affecting Radon Entry in New Residential Construction
Various conditions in a house can commonly produce house negative pressures up to 20 Pascals relative to the soil gas pressure. Depressurization of the house relative to the soil gas will...

Estimation of Infiltration Rates from a Landfill
The Landfill Source Model (LSM) provides a physically-based, computationally efficient estimate of leachate emanating from a landfill. The model is PC-based and simulates a number of surface...

The MSU Sprinkling Infiltrometer: A Device to Measure Time-to-Ponding
Time-to-ponding can be determined quickly and with minimal disturbance to the soil surface by the use of a sprinking infiltrometer developed at Michigan State University (MSU). Solenoid...

Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...

Infiltration Trenches for Urban Runoff Control
A two-dimensional finite element model has been developed to simulate the transient flow in a variably saturated porous medium for the study of infiltration trenches. Parameters such as...

Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...

Successful Rehabilitation of Sewers at Hawaii Kai
Two common problems in sanitary sewer deterioration are hydrogen sulfide attack to concrete pipe and structures and infiltration leakage into the system. Within the 100 miles (160 km)...

Comprehensive Rehabilitation Results From Stege Sanitary District
Seven sewer agencies, including Stege Sanitary District, in the East Bay of the San Francisco Bay Area embarked on a 20-year capital improvement program in 1987. The 300 million construction...

Use of In-Place Lateral Reconstruction for Correction of Infiltration/Inflow
Extensive sewer collection system rehabilitation programs have done much and will continue to correct infiltration/inflow problems. However, re-evaluation of some of the earlier projects...

Evaluation of Infiltration Equations Used in Surface Irrigation
Computer simulations of an irrigation event were conducted using 6 full hydrodynamic models. All 6 models used the same surface flow equations and a different infiltration component. The...

Hydraulic Studies of Surface Drainage from Level Furrows
Field studies have been completed to quantify the surface drainage phenomenon from level furrows which were rapidly flooded and then drained from the inlet end of the furrow. The proportion...

Design and Construction of Infiltration Trenches
This paper discusses the use of infiltration trenches as a stormwater management practice. Feasibility, design and construction techniques are presented to improve the performance and...

Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...

Systems for Artificial Recharge of Ground Water
Design and management of infiltration systems should be adapted to local conditions of water quality, climate, soil, hydrogeology, and environmental constraints. Aspects to be considered...

Artificial Recharge Research at the University of Arizona
This paper summarizes pit- and well-recharge trials at Tucson, Arizona. The pit recharge trials examined management techniques and characterized flow patterns in the 80 ft thick vadose...

Feasibility of Artificial Recharge to the Oakes Aquifer, Southeastern North Dakota
Based on measured well yields, initial surface infiltration rates, and ground-water quality, the Oakes aquifer can support a large-scale artificial recharge-irrigation project. An aquifer...

Hydraulic Effect of Turbid Water Infiltration Through a Shallow Basin
A 225 m2 test basin was operated from September 1986 through October, 1987, to determine the hydraulic effects of turbid water application. Initial...

Artificial Recharge and Water Supply in The Netherlands
In 1984 infiltration by surface spreading was 156 million m3, serving 15% of total supply of drinking water in the Netherlands. Already for some...
