Field evaluation of a polymer sealant for canal seepage reduction

Agricultural Water Management, 2021
Abstract A large amount of the water diverted for irrigated agriculture seeps from earthen canals during its conveyance to fields. Besides a shortfall in water availability, a variety of environmental and economic damages are caused by canal seepage.

Field tests and model analyses of seepage into drift

Journal of Contaminant Hydrology, 1999
Abstract This paper focuses on field test results and model analyses of the first set of five niche seepage tests conducted in the Exploratory Studies Facility at Yucca Mountain. The test results suggest that (1) a niche opening (short drift excavated for this study) acts as a capillary barrier; (2) a seepage threshold exists; and (3) the seepage is ...

Simulation of the Seepage Field in the Danjiangkou Reservoir Area

Applied Mechanics and Materials, 2011
According to the geological conditions of the Danjiangkou reservoir, the computational model was set up considering fracture zones and the changing along the depth of mechanical properties of rock. Adopting this model, the seepage field of the reservoir area was simulated for long time, which shows that: 1) The medium and small earthquakes in the ...

Seepage in Field Geology and Petroleum Exploration

2015
Rock permeability to gas and a gas source are the basic preconditions for gas seepage. Seepage can then provide information regarding the location and nature of the source and the migration pathway. In the modern fossil fuel industry, natural hydrocarbon seepage provided the first clues for petroleum and natural gas explorations.

Coupling Law of Mixed Gas Seepage Field and Concentration Field in Goaf

AIP Conference Proceedings, 2011
Gas permeability affects the flow pattern of whole goaf gas and leakage airflow. Mathematical model of goaf gas flow has been improved in this paper by adding space distribution equations of porosity porosity and gas permeability in goaf. Coupling law of mixed gas 3D seepage field and concentration field in goaf has been studied.

The magnitude and variability of lateral seepage in California rice fields

Journal of Hydrology, 2019
Abstract Lateral seepage can be an important water loss pathway at the field level and a conduit for the discharge of pesticides and nutrients from rice fields. However, few studies have directly measured lateral seepage rates in flooded rice fields. This study sought to characterize the magnitude and variability of lateral seepage in California rice

Analytical Solutions for Seepage Field of Underwater Tunnel

2018
Based on the patterns of the hydraulic head outside the lining layer obtained from numerical simulation, a new boundary condition for the tunnel is proposed that the hydraulic head appears sinusoidal distribution on the lining’s external circumference.

Field investigations of seepage in the Inguri arch dam

Hydrotechnical Construction, 1981
1. Field observations of the concrete masonry of the Inguri dam show impermeability of the high-quality compacted concrete and interblock joints. Seepage in the galleries is confined mainly to the ungrouted intersectional joints and defective zones of the concrete masonry. 2.
