Successful Treatment of an MTBE-impacted Aquifer Using a Bioreactor Self-colonized by Native Aquifer Bacteria [PDF]

open access: yes, 2013
A field-scale fixed bed bioreactor was used to successfully treat an MTBE-contaminated aquifer in North Hollywood, CA without requiring inoculation with introduced bacteria. Native bacteria from the MTBE-impacted aquifer rapidly colonized the bioreactor,

Local development organisations in Saharan regions of North Africa: Expanding horizons

open access: yesJournal of International Development, Volume 35, Issue 1, Page 79-96, January 2023., 2023
Abstract Local development organisations are now widespread in rural regions of North Africa. In the past, these organisations were usually only involved in a few sector‐specific activities. This study investigated the activities of 24 local development organisations in the Saharan regions of Morocco, Algeria and Tunisia.

Bayesian Poroelastic Aquifer Characterization from InSAR Surface Deformation Data. Part I: Maximum A Posteriori Estimate [PDF]

open access: yes, 2020
Characterizing the properties of groundwater aquifers is essential for predicting aquifer response and managing groundwater resources. In this work, we develop a high-dimensional scalable Bayesian inversion framework governed by a three-dimensional quasi-static linear poroelastic model to characterize lateral permeability variations in groundwater ...

Estimation of aquifer lower layer hydraulic conductivity values through base flow hydrograph rising limb analysis [PDF]

open access: yes, 2010
The estimation of catchment-averaged aquifer hydraulic conductivity values is usually performed through a base flow recession analysis. Relationships between the first time derivatives of the base flow and the base flow values themselves, derived for ...

From wasteland to oasis: Transformative effects of trees on farmland and livelihoods

open access: yesLand Degradation &Development, Volume 33, Issue 18, Page 3773-3785, December 2022., 2022
Abstract In face of today's alarming trend of resource degradation and reversal of poverty reduction, path‐breaking strategies are needed. However, there is limited evidence to inform the design of policies. We scrutinized an agricultural development program that follows a holistic approach and includes the cultivation of fruit trees, to tackle this ...

Anthropogenic depletion of Iran’s aquifers [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
Significance Iran is facing a state of water bankruptcy that threatens its socioeconomic development and natural environments. Using an exceptionally rich measured groundwater dataset, we illustrate the extent and severity of Iran’s groundwater depletion and salinization problems during the 2002 to 2015 period, when the number of

Response Of The Dupi Tila Aquifer to intensive pumping in Dhaka, Bangladesh [PDF]

open access: yes, 2003
This paper focuses on the water-quantity issues facing Dhaka because of the rapid exploitation of the Dupi Tila aquifer. Dhaka is one of the world’s largest groundwater-dependent cities, relying on water withdrawn from this underlying semiconfined sand ...
