The literature's current state of the art and future research directions for risk management in the construction sector are described and analyzed in this paper. Web of Science and VOSviewer-Based Literature: A Bibliometric and Visualization Tool. A web of science core collection of 676 research publications on risk management and the construction sector written between 2000 and 2021 was examined. The work investigates cluster analysis, co-occurrences analysis of authors' keywords, and mapping of bibliographic coupling. Results show the contribution of 61 authors from 80 countries, 45 institutions, and 20 keywords were identified and organized in three clusters: Risk management in construction project management, Enterprise risk management in the construction sector, and Effective project management for the construction project success.

Abstract: The article presents the main features of a floating photovoltaic cover system (FPCS) for water irrigation reservoirs whose purpose is to reduce the evaporation of water while generating electrical power. The system consists of polyethylene floating modules which are able to adapt to varying reservoir water levels by means of tension bars and elastic fasteners. [Copyright &y& Elsevier]

Abstract: The article presents the main design features and photovoltaic requirements of a FPCS (floating photovoltaic cover system) for water irrigation reservoirs whose purpose is to reduce the evaporation of water while generating electrical power. Also, a summary of installation costs and relationship with the yield performance is deeply analyzed. A prototype of 20 kWp was implemented, and given the success of the results observed, the whole surface reservoir was covered (4490 m2 and 300 kWp). The paper analyses the first electricity productions of the system and from these data the CO2 balance of the facility is calculated. [Copyright &y& Elsevier]
