In recent years, many disasters due to floods have occurred around the world. In some cases, the level of river water exceeded the estimated high-water level. It is necessary, therefore, to reconsider the evaluation method for river dike embankments during floods for the safety of the embankments. In this study, a deformation analysis is proposed that can simultaneously consider the unsaturated...

Quantifying groundwater flow at seepage faces is crucial because seepage faces influence the hydroecology and water budgets of watersheds, lakes, rivers and oceans, and because measuring groundwater fluxes directly in aquifers is extremely difficult. Seepage faces provide a direct and measurable groundwater flux but there is no existing method to quantitatively image groundwater processes at th...

There are various evaluation methods available for the discharge rate passing from the body of dam 1) Analytical methods, 2) Numerical methods and 3) Experimental methods. In the initial stages of dam design, it is necessary to approximately calculate the seepage and board of the project. In this research, almost 600 geometric models have been considered for embankment dam with clay core which ...

Deeply buried groundwater, such as brine, is an important industrial raw material with high economic value. Because brine frequently exists under higher temperature and pressure, the quantitative prediction of its seepage field is very difficult. Here we study the migration of deeply buried groundwater by using a numerical simulation based on laboratory test results. In particular, we express t...

Seepage of geological methane through sediments Arctic lakes might contribute conceivably to the atmospheric budget. However, abundance and precise locations such seeps are poorly quantified. For Lake Neyto, one largest on Yamal Peninsula in Northwestern Siberia, temporally expanding regions anomalously low backscatter C-band SAR imagery acquired late winter spring have been suggested be relate...

piping sometimes is occurred due to seepage of water in hydraulic structures. the continuty of this phenomenon decreases the safety or caused the failure of a structure. in this work, experimental tests were carried out on statically compacted natural and randomly reinforced silt sandy soil samples. the randomly reinforced samples were prepared with different lengths and percentages of an artif...

Rainfall infiltration exerts great effect on the stability of soil slopes. Based on the actual rainfall data, saturated-unsaturated seepage theory and the mechanical theory of unsaturated porous media, numerical simulations were conducted to examine the seepage field of saturatedunsaturated slope during rainfall infiltration in this paper. The influence of the coefficient with rainfall duration...

estimation of seepage from water channels are necessary in evaluating water productivity in agricultural sector as affected by floodwater spreading on plains and artificial recharge of groundwater. several empirical seepage equations have been developed for this purpose. previous research results in iran have shown lots of variation in the coefficients and the empirical equations change in diff...

Seabed hydrocarbon seeps present natural laboratories for investigating responses of marine ecosystems to petroleum input. A seep near Scott Inlet, Baffin Bay, was visited in situ observations and sampling the summer 2018. Video evidence an active confirmed by methane analysis overlying water column, which is 260 m at this site. Elevated concentrations bottom above down current from decreased b...

Relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. Placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. Relief wells are often used in combina...
