Water is essential for life. Specifically in the oases of inland arid basins, water is a critically limited resource, essential for the development of the socio-economy and the sustainability of eco-environmental systems. Due to the unique hydrological regime present in arid oases, a moderate groundwater table is the goal of sustainable water management. A shallow water table induces serious se...

In this study, the 2D steady-state seepage analysis of dam body and its base is investigated using finite element method based on Galerkin’s approach. The foundation soil are considered as homogeneous isotropic anisotropic materials effects horizontal drainage length cutoff wall investigated. differential equation governing response water in obtained with help Darcy's law continuity equations. ...

Intermontane basins in the Trans-Pecos region of westernmost Texas and northern Chihuahua, Mexico, are target areas for disposal of interstate municipal sludge and have been identified as possible disposal sites for low-level radioactive waste. Understanding ground water movement within and between these basins is needed to assess potential contaminant fate and movement. Four associated basin a...

The discharge from most karst springs exhibits a consistent and reasonably predictable response to recharge but few exhibit short-term (‘rhythmic’) changes in flow that are commonly attributed the geometry of feeder conduits action siphons. This paper investigates water system rhythmic episodic due variations two phreatic (Main Rising (MR) Whirlpool (WR)) pass through Speedwell Cavern en route ...

Taking the 14,030 panel of Zhaogu No. 2 coal mine as its research object, this paper studies evolution characteristics developing height, propagation track and caving arch shape water-flowing fractures under influence thick alluvium by utilizing a physical experiment, theoretical analysis field investigation. The results show that height limit span fracture zone experience four stages, which in...
