Dams, Dams and More Dams: Issues in Evaluating Business Cases for Dam Expansion in Australia
Environmental Research Communications, 2023 Abstract Conventional interventions for mitigating flood risk and increasing water security often focus on large-scale engineering solutions despite evidence of significant cost overruns and negative environmental impacts. This study is an example of participatory research in water economics, motivated (and requested) by concerns from ...

GeoHumanities, 2021 [EN] Over the last five decades, Italy has invested in the construction of public works as the core strategy to dynamize its less favoured regions; however, due to multiple and inherent dysfunctionalities, many of these remain half-built and abandoned today. The group of artists Alterazioni Video refer to this phenomenon as “Incompiuto” (“Incompletion”

The use of frozen semen to minimize inbreeding in small populations [PDF]
, 2002 In this study, we compared the average coancestry and inbreeding levels for two genetic conservation schemes in which frozen semen from a gene bank is used to reduce the inbreeding in a live population.

Discharge predicted in compound channels using adaptive neuro-fuzzy inference system (ANFIS)
Open Engineering, 2023 Some hydraulic structures and phenomena, including compound channels, must be studied in relation to open channel flow. Despite the fact that the primary channel and watersheds share a similar degree of roughness, estimating discharge in composite ...
