Rainwater harvesting systems and flood water management in rural areas: A systematic review

and –

In a climate marked by prolonged drought, observed mainly in arid and semi-arid areas, the installation of hydraulic systems for rainwater collection and storage in rural and isolated areas is becoming a necessity to preserve livestock and ensure water security for the local popula-tion. For this purpose, this review synthesizes recent studies on the various hydraulic systems used for rainwater harvesting (RWH) in rural areas to support agriculture, livestock, and households. This review examines 66 relevant studies published in journals indexed in ScienceDirect and Scopus over a period of five years (January 2021 – December 2025). It emphasizes the importance of design based on the specific characteristics of each location or country, the criteria for selecting implementation sites, the impact of RWH systems on agricul-ture, livestock, and rural households, existing challenges, and proposes some guidelines for sustainable rainwater management and flood reduction.

The impact of hydrological extremes on ponds and small water reservoirs

and –

This paper presents the methodological approach and key results of the research project Design of ponds and small reservoirs in terms of the possibility to comply with MPF and flood safety (TA CR, no. SS03010230). The project focused on the assessment of ponds, pond systems and small reservoirs in relation to two hydrological extremes – draught and floods. During periods of drought, the issue of maintaining the minimum residual flow is addressed. The article describes the method of determining and maintaining the minimum residual flow at these hydraulic structures. Furthermore, the article deals with the assessment of the security of these structures in terms of the safe discharge of flood flows in accordance with ČSN 75 2935 – Assessment of the safety of hydraulic structures during floods.
