Hydraulic diffusivity is a fundamental parameter in studying groundwater flow. An analytical solution for flow within finite-length one-dimensional aquifer has been introduced. This simplifies the river water level (RWL) by piecewise linear function, accurately describing arbitrary variation pattern. inversion method hydraulic provided based on solution. Then, was employed to estimate of limest...

The vast continent of Africa is a land of contrasts—from the sophisticated urban and industrial centers of Cape Town and Johannesburg to the rural bushlands and mountains of Zimbabwe and Kenya. As in the rest of the world, groundwater resources in Africa are critical to human livelihood, agricultural and industrial development, and maintenance of aquatic ecosystems. Widely available scientific ...

The present study aims to estimate the residence-time of groundwater based on bomb-produced Cl. Water samples were collected from some selected wells located around Al-Zulfi province, Riyadh central region, Saudi Arabia. Cl/Cl ratios in the water samples are determined by Inductively Coupled Plasma Mass Spectrometry (ICPMS) and Liquid Scintillation Counting (LSC). Cl/Cl ratios in the groundwate...

This work develops a rule curve-based conjunctive use management model for optimizing the operating rules for a lake–groundwater system with off-stream storage lakes. The proposed procedure is a simulation-optimization approach that embeds an Artificial Neural Network (ANN) instead of a groundwater numerical model into a genetic algorithm (GA). The direct physical exchange between lake water wi...

Streambed temperatures can be easily, accurately and inexpensively measured at many locations. To characterize patterns of groundwater-stream water interaction with a high spatial resolution, we measured 140 vertical streambed temperature profiles along a 220m section of a small manmade stream. Groundwater temperature at a sufficient depth remains nearly constant while stream water temperatures...

[1] This study evaluates regional-scale hydrological simulations of the newly developed community Noah land surface model (LSM) with multiparameterization options (Noah-MP). The model is configured for the Mississippi River Basin and driven by the North American Land Data Assimilation System Phase 2 atmospheric forcing at 1/8° resolution. The simulations are compared with various observational ...
