Long-term drought monitoring of the Zayandehrud River basin (central Iran) using hydroclimatological models and satellite observations

Babadi, Masoud (author), Iran Pour, Siavash (author), Roscher, Ribana (author), Amiri Simkooei, A. (author), Karimi, Hamed (author)

Drought is one of the most complex and threatening disasters, defined as a period of drier-than-normal conditions which results in water-related problems. In addition to climate variation, human activities can cause or intensify drought through groundwater overextraction, unsupervised expansion of agricultural lands, etc. One prime example of...

Irrigation on the move: How transient farming partnerships facilitate the expansion of smallholder irrigation along ephemeral rivers in dryland areas of Kenya

Karimba, Benson Mutuma (author), Duker, Annelieke (author), Prasad, Pooja (author), Karimi, Poolad (author), de Fraiture, Charlotte (author), van der Zaag, P. (author)

Irrigation is commonly viewed as an activity fixed in time and place requiring permanent infrastructure. However, smallholder farmers in Sub-Saharan Africa engage in irrigation in diverse locations under different organizational modalities. This research analyses a flexible and dynamic form of irrigation driven by unique partnerships between...

Experimental and density functional theory studies of laminar double-oxidized graphene oxide nanofiltration membranes

Valizadeh, Solmaz (author), Naji, Leila (author), Karimi, Mohammad (author), Sarabadani Tafreshi, Saeedeh (author), Heijman, Sebastiaan (author), de Leeuw, Nora H. (author)

The type and loading level of oxygen-containing functional groups on graphene oxide (GO) nanosheets significantly affect the size and alignment of nanochannels formed between the GO nanosheets and the separation performance of laminar GO membranes. Here, we demonstrate how double-oxidation of GO leads to the higher surface charge of GO...

Dynamic pricing and inventory control policies in a food supply chain of growing and deteriorating items

Pourmohammad-Zia, Nadia (author), Karimi, Behrooz (author), Rezaei, J. (author)

Revenue and inventory management play a crucial role in the operational efficiency of food supply chains. The current study investigates dynamic pricing and inventory control policies in a two-level Food Supply Chain (FSC) of growing and deteriorating inventory that involves a rearing farm as the supplier and a retailer where these...

Food supply chain coordination for growing items: A trade-off between market coverage and cost-efficiency

Pourmohammad-Zia, Nadia (author), Karimi, Behrooz (author), Rezaei, J. (author)

The accurate operation of a Food Supply Chain (FSC) is a critical issue as it directly interfaces with health and safety matters. This study addresses coordination and conflict management in a three-level FSC that embraces a new inventory type known as growing items like poultry and livestock. The chain involves a rearing farm as the supplier...

Multi-twist polarization ribbon topologies in highly-confined optical fields

Bauer, T.A. (author), Banzer, Peter (author), Bouchard, Frédéric (author), Orlov, Sergej (author), Marrucci, Lorenzo (author), Santamato, Enrico (author), Boyd, Robert W. (author), Karimi, Ebrahim (author), Leuchs, Gerd (author)

Electromagnetic plane waves, solutions to Maxwell's equations, are said to be 'transverse' in vacuum. Namely, the waves' oscillatory electric and magnetic fields are confined within a plane transverse to the waves' propagation direction. Under tight-focusing conditions however, the field can exhibit longitudinal electric or magnetic...

From global goals to local gains—a framework for crop water productivity

Blatchford, Megan Leigh (author), Karimi, Poolad (author), Bastiaanssen, W.G.M. (author), Nouri, Hamideh (author)

Crop water productivity (CWP) has become a recognised indicator in assessing the state of Sustainable Development Goals (SDG) 6.4—to substantially increase water use efficiency. This indicator, while useful at a global scale, is not comprehensive at a local scale. To fill this gap, this research proposes a CWP framework, that takes advantage...

Spatial evapotranspiration, rainfall and land use data in water accounting. Part 1: Review of the accuracy of the remote sensing data

Karimi, P. (author), Bastiaanssen, W.G.M. (author)

The scarcity of water encourages scientists to develop new analytical tools to enhance water resource management. Water accounting and distributed hydrological models are examples of such tools. Water accounting needs accurate input data for adequate descriptions of water distribution and water depletion in river basins. Ground-based...

Water Accounting Plus (WAC) is a framework that summarizes complex hydrological processes and water management issues in river basins. The framework is designed to use satellite-based measurements of land and water variables and processes as input data. A general concern associated with the use of satellite measurements is their accuracy. This...
