Effects of pulse wave on the variation of coal pore structure in pulsating hydraulic fracturing process of coal seam

, 2020
Coal pore structure is not only closely related to gas adsorption, but also affect the dynamic characteristics of gas desorption and diffusion. In order to understand the influence of pulsating hydraulic fracturing on the variation of coal pore structure,

Landslides and hydraulic structures

Engineering Geology, 2021
Abstract The paper discusses two types of hydraulic structures: a) Hydraulic canals and penstocks. They are sensitive structures which typically do not tolerate ground displacements. Two cases are described: the Izbor canal and the Pampaneira penstock.

Structure and hydraulic properties in soils under long-term irrigation with treated wastewater

Geoderma, 2019
Secondary treated wastewater, a commonly used water resource in agriculture in (semi-)arid areas, often contains salts, sodium, and organic matter which may affect soil structure and hydraulic properties.

Long-term effects of conventional and reduced tillage on soil structure, soil ecological and soil hydraulic properties

Geoderma, 2018
There is a long-lasting debate about the effects of tillage practices on soil structure and structure-mediated ecosystem properties like hydraulic conductivity and crop productivity.

Hydraulic structures and/or the environment?∗

C R C Critical Reviews in Environmental Control, 1980
As implied by its title, the paper traces the development of an apparent conflict between technology and ecology, including aspects of population growth, resource availability, and waste. Practices of the Corps of Engineers and the Bureau of Reclamation are considered, and their culmination in passage of the National Environmental Policy Act with its ...
