Water reservoir techniques using remote sensing and GIS: a literature survey

Published in Journal of Physics: Conference Series

The issue of storing flood waters caused by rains and river floods is very important to address the problems of drought. This study reviewed the latest research to address the problems of water scarcity and conservation with advanced methods. these study methodologies range from employing Geographic Information Systems Programs to handle and analys...

Watershed management, groundwater recharge and drought resilience : An integrated approach to adapt to rainfall variabil...

Rainfall variability coupled with poor land and water management is contributing to food insecurity in many sub-Saharan African countries such as Ethiopia. To address such challenges, various efforts have been implemented in Ethiopia. The objective of this study was to evaluate the long-term impacts of different soil and water conservation and wate...

Multi-bioinspired hierarchical integrated hydrogel for passive fog harvesting and solar-driven seawater desalination

Published in Chemical Engineering Journal

In recent years, with the outbreak and epidemic of the novel coronavirus in the world, how to obtain clean water from the limited resources has become an urgent issue of concern to all mankind. Atmospheric water harvesting technology and solar-driven interfacial evaporation technology have shown great potential in seeking clean and sustainable wate...

Estimating the runoff response from hillslopes treated with soil and water conservation structures in the semi-arid Ethi...

Planning and management of water resources is crucial to enhance agricultural productivity and ensure food security in drylands. For this, adaptable and reliable runoff prediction models are urgently needed to support water harvesting and irrigation development. In this study we explored the potential of the runoff Curve Number (CN) method to estim...

Water harvesting on biomimetic material inspired by bettles.

Published in Heliyon

Many organisms in nature such as beetles and cacti can survive in arid places by their own surface structures that are still able to collect mist. These surfaces have micro-nano structures that maintain a very low adhesion, allowing them to continuously collect and transport water. Here, we used a light curing three dimensional molding process to c...

The role of emergent and developing countries in the 21st century: A vision for sustainable housing development in Benin...

At the same time that we’re solving climate change, we are building cities for another 3 billion people until 2050. That’s a doubling of the urban environment. The most extensive of this construction, and especially housing projects for the coming decades, will take place in emergent and developing countries. We, as architects, engineers, developer...

3D-printed spider-web structures for highly efficient water collection.

Published in Heliyon

Fog and moisture in nature are important freshwater resources, and the collection of these fog water is of great significance to arid regions. Inspired by the unique geometric structure of the spindle knot on spider silk, artificial fibers with periodic structures have been fabricated for water collection, which can effectively alleviate the proble...

Sand dams for sustainable water management: Challenges and future opportunities

Sand dams are impermeable water harvesting structures built to collect and store water within the volume of sediments transported by ephemeral rivers. The artificial sandy aquifer created by the sand dam reduces evaporation losses relative to surface water storage in traditional dams. Recent years have seen a renaissance of studies on sand dams as ...
