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...
Quality Changes of River Rhine and Meuse Water Upon Basin Recharge in the Netherlands' Coastal Dunes: 30 Years of Experience
A wide spectrum of quality changes of river Rhine and Meuse water is presented, on a global scale after pre-treatment, dune infiltration and post-treatment. Attention is focussed on the...
Infiltration Wells in the Lakes Around the Future Markerwaard Polder
Drainage and reclamation of the Markerwaard polder in the Netherlands may cause damage to buildings and infrastructure in the eastern part of North-Holland because of subsidence. Drawdown...
Artificial Recharge of the Heretaunga Plains Aquifer Hawke's Bay, New Zealand
The Heretaunga Plains groundwater system in the Hawke's Bay region of New Zealand, is naturally recharged from the nearby Ngaruroro River at the approximate rate of 5.5m3/sec....
Techniques of Artificial Recharge from an Ephemeral Wadi Channel Under Extreme Arid Conditions
A series of field experiments and theoretical analysis was carried out for the alluvial system in Wadi Tabalah in order to determine the feasibility of implementing artificial recharge...
Deepwell Infiltration in the North-Holland Dune Area
Deep well infiltration now generally is considered the cue for the future extensions of artificial ground water recharge in or outside the dunes. The Provincial Waterworks of North-Holland...
Interactive Surface Irrigation Design and Evaluation Software
This paper outlines the features and capabilities of a comprehensive personal computer software system for use by irrigation engineers in design and evaluation of continuous and surge...
Comparison of Surge and Continuous Flow Irrigation in California
With the closure of the Kesterson National Wildlife Refuge to drainwater disposal and the pending limits on tailwater flows to the San Joaquin River, decreasing deep percolation is of...
Infiltration as a Dependent Variable in Modeling Furrow Irrigation
Most surface irrigation models assume that infiltration is independent of surface flow hydraulics. However, wetted perimeter has been shown to significantly affect infiltration in furrows....
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,...
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...
