Influence of borehole quantity and distribution on lithology field simulation

NAN Tian, GUO Si-jia

2019, 7(4): 295-308. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.001

[摘要](585) PDF(295)

摘要:
This paper aims to study the influence of the number and distribution of drill samples on the simulation accuracy of the lithology field. This research mainly applies the variation function method in geo-statistics, and determines important indicators such as the variation, and then the lithology fi...

Mapping potential areas for groundwater storage in the High Guir Basin (Morocco):Contribution of remote sensing and geographic information system

Nouayti Abderrahime, Khattach Driss, Hilali Mohamed, Nouayti Nordine

2019, 7(4): 309-322. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.002

[摘要](1286) PDF(379) [施引文献] (17)

摘要:
Identification of water potential areas in arid regions is a crucial element for the enhancement of their water resources and socio-economic development. In fact, water resources system-planning can be used to make various decisions and implement management of water resources policies. The purpose o...

Numerical investigation of hydraulic characteristics and prediction of cavitation number in Shahid Madani Dam's Spillway

Babak Ghazi, Rasoul Daneshfaraz, Esmaeil Jeihouni

2019, 7(4): 323-332. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.003

[摘要](926) PDF(291) [施引文献] (6)

摘要:
The prediction of the probability of cavitation occurrence to prevent serious damages in the spillways is the major concern for hydraulic engineers. In this research, the three-dimensional model of Shahid Madani Dam’s spillway was simulated with the Flow 3D software and by the comparison of numerica...

Evolution trend of the water quality in Dongping Lake after South-North Water Transfer Project in China

HU Zun-fang, KANG Feng-xin, ZOU An-de, YU Lin-song, LI Yang, TIAN Tong-liang, KANG Gui-ling

2019, 7(4): 333-339. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.004

[摘要](601) PDF(218) [施引文献] (5)

摘要:
To investigate the evolution trend of water quality in Dongping Lake after South-North Water Transfer Project operation as well as to ensure the safe usage of the water receiving areas, water samples were collected and determined before and after water delivery in different hydrological seasons. The...

Visualizing the spatial water quality of Bentota, Sri Lanka in the presence of seawater intrusion

T K G P Ranasinghe, R U K Piyadasa

2019, 7(4): 340-353. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.005

[摘要](629) PDF(174) [施引文献] (1)

摘要:
Seawater flows towards the inlands along with the rivers and canals, through the process of infiltration and leaks in the ground water characterized by high concentrations of soluble salts. High salinity concentrations can make groundwater unsuitable for public consumption and surface water unsuitab...

Height prediction of water flowing fractured zones based on BP artificial neural network

YANG Liu, WEN Xue-ru, WU Xiao-li, PEI Li-xin, YUE Chen, LIU Bing, GUO Si-jia

2019, 7(4): 354-359. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.006

[摘要](610) PDF(238) [施引文献] (7)

摘要:
Factures caused by deformation and destruction of bedrocks over coal seams can easily lead to water flooding (inrush) in mines, a threat to safety production. Fractures with high hydraulic conductivity are good watercourses as well as passages for inrush in mines and tunnels. An accurate height pred...

Electrical-hydraulic conductivity model for a weathered-fractured aquifer system of Olbanita, Lower Baringo Basin, Kenya Rift

SOSI Benjamin, BARONGO Justus, GETABU Albert, MAOBE Samson

2019, 7(4): 360-372. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.007

[摘要](504) PDF(259) [施引文献] (1)

摘要:
Groundwater yield in the Kenya Rift is highly unsustainable owing to geological variability. In this study, field hydraulic characterization was performed by using geo-electric approaches. The relations between electrical-hydraulic (eh) conductivities were modeled hypothetically and calibrated empir...

Adaptive state estimation of groundwater contaminant boundary input flux in a 2-dimensional aquifer

Muhammad Nauman Malik, Mehdi Murtuza, Iqbal Asif, Bakar Muhammad Saifullah Abu, Brahim Aissa, Dk Nur Afiqah Jalwati Puteri, Amer Farhan Rafique

2019, 7(4): 373-382. doi: DOI: 10.19637/j.cnki.2305-7068.2019.04.008

[摘要](635) PDF(176) [施引文献] (1)

摘要:
In many circumstances involving heat and mass transfer issues, it is considered impractical to measure the input flux and the resulting state distribution in the domain. Therefore, the need to develop techniques to provide solutions for such problems and estimate the inverse mass flux becomes impera...
