Cogent Engineering, 2019 This study estimated groundwater recharge response from rainfall events in a semi-arid fractured aquifer. This is crucial as recharge response has an influence on available groundwater in an aquifer.

Combining the Morris Method and Multiple Error Metrics to Assess Aquifer Characteristics and Recharge in the Lower Ticino Basin, in Italy [PDF]
arXiv, 2022 Groundwater flow model accuracy is often limited by the uncertainty in model parameters that characterize aquifer properties and aquifer recharge. Aquifer properties such as hydraulic conductivity can have an uncertainty spanning orders of magnitude. Meanwhile, parameters used to configure model boundary conditions can introduce additional uncertainty.

Groundwater age, life expectancy and transit time distributions in advective-dispersive systems: 1. Generalized reservoir theory [PDF]
Advances in Water Resources 29 (2006) 1267-1291, 2011 We present a methodology for determining reservoir groundwater age and transit time probability distributions in a deterministic manner, considering advective-dispersive transport in steady velocity fields. In a first step, we propose to model the statistical distribution of groundwater age at aquifer scale by means of the classical advection ...

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 808-826, December 2022., 2022 The Ngorongoro Conservation Area (NCA), a UNESCO World Heritage Site, is globally important for biodiversity conservation due to the presence of iconic megafauna. For decades now, the NCA is experiencing a number of notoriously difficult to address challenges; understanding its land cover dynamics is therefore increasingly important to improve habitat ...

Irrigation water use efficiency: A water balance approach
River, Volume 1, Issue 2, Page 142-148, November 2022., 2022 A water use framework that covers four levels of water management infrastructure: the water source, bulk conveyance system, the irrigation scheme, and the irrigation farm can be used to improve irrigation efficiency. The water balance approach can be applied at any level, within defined boundaries, or across all levels to assess performance within the ...

Predicting Playa Inundation Using a Long Short-Term Memory Neural Network [PDF]
, 2020 In the Great Plains, playas are critical wetland habitats for migratory birds and a source of recharge for the agriculturally-important High Plains aquifer. The temporary wetlands exhibit complex hydrology, filling rapidly via local rain storms and then drying through evaporation and groundwater infiltration.
