Analysis of Groundwater Balance of Samalqan Plain Aquifer Using SWAT and MODFLOW Models

علوم آب و خاک, 2021
Reducing surface water resources and successive droughts and consequently excessive use of groundwater resources, especially for agricultural purposes, have caused irreparable damage to the natural resources of the country.

A Columbia River Basalt Group Aquifer in Sustained Drought: Insight from Geophysical Methods

Resources, 2015
Aquifers within the Columbia River Basalt Group (CRBG) provide a critical water supply throughout much of the Pacific Northwest of the United States. Increased pumping has resulted in water level declines in this region. Recharge into this aquifer system

Optimal Recharging With Practical Considerations in Wireless Rechargeable Sensor Network

IEEE Access, 2017
Wireless energy transfer technologies have attracted increasing attention on empowering the wireless sensor nodes in recent years. In this paper, we consider a typical wireless rechargeable network, where a mobile charging vehicle is scheduled to charge a wireless sensor network with practical nodes' deployment restrictions that may result in low ...

Efficient and Robust Standing Postures of Quadruped Robots

Advanced Robotics Research, EarlyView.
A calibrated static framework estimates load, optimizes torques, and adapts posture so quadruped robots stand efficiently and robustly under external payloads, achieving up to 50% lower torque demand. Inspired by the natural posture adjustments of animals under external loading, this article presents an optimization‐based framework for minimizing joint

Spatial variability of groundwater recharge - II. Factors affecting variability and taking account of it in estimating recharge

, 2004
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even at small distances, if there appear to be a frequency ...

Recharge through drift. Progress Report [PDF]

, 2001
The overall objective of this study is to quantify amounts of recharge to aquifers overlain by a covering of drift and to understand the flow mechanisms by which this occurs.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

The estimation of groundwater recharge by soil water balance in semi-arid regions

, 2002
Quantification of groundwater recharge is a crucial prerequisite for sustainable groundwater resource management, particularly in semi-arid areas where there are large demands for groundwater supplies. This research presents an alternative approach for

A Study of Sensitive Fault Detection for Lithium-Ion Batteries Being Recharged Using Support Vector Machine Classifier and Receiver Operating Characteristics

Applied Sciences
Several installations equipped with lithium-ion batteries may require additional precautions. While lithium-ion batteries offer good performance relative to other rechargeable batteries, their state of health should be monitored.

Kinematic diffusion approach to describe recharge phenomena in unsaturated fractured chalk

Journal of Hydrology and Hydromechanics, 2017
When dealing with groundwater resources, a better knowledge of the hydrological processes governing flow in the unsaturated zone would improve the assessment of the natural aquifer recharge and its vulnerability to contamination.
