Summary: Rainwater collection systems often include a first flush volume to divert contaminants away from collected and stored rainwater. Environmental and collection system parameters can vary the volume of the first flush necessary to effectively divert contaminants. A study conducted in Amherst, Massachusetts assessed the quality of rainwater in a test-scale collection system and found that higher intensity storms and environmental conditions affected the necessary first flush volumes.

Summary: Water resources management is crucial for rural communities in drylands, and water harvesting technologies can play a significant role in intercepting surface runoff and storing water. This study aims to fill the knowledge gap on the performance of Marab technology in different environments by simulating its hydro-agrological effects using the AquaCrop model. The simulation-based assessment reveals that Marab-based farming has a huge improvement potential for barley production, with an average yield of 8.37 t ha(-1) compared to a highly variable yield of 0.34 t ha(-1) without the technology.

Summary: With increasing water scarcity and demand worldwide, rainwater harvesting (RWH) is being considered as a feasible way to supplement water supply. The success of RWH systems depends on factors like rainfall, catchment characteristics, and socio-economic aspects. Location-specific studies are essential to evaluate the potential of RWH in a particular area. The study in Johannesburg found that at least 50% of the city is suitable for RWH, and despite seasonal rainfall, adequate storage can make RWH systems feasible.

Summary: This paper conducts a feasibility study on a rainwater harvesting system in the Ryomyong street, Pyongyang, the DPR Korea, analyzing the runoff coefficient and reliability of buildings with green roofs and a rooftop greenhouse. The results show that the green roofs have an average annual runoff coefficient of 0.12 and monthly coefficients ranging from 0 (Jan.-Apr., Oct.-Dec.) to 0.58 (Jul.) over a period of 37 years. Additional rainwater collection is needed from other sources for irrigation in the greenhouse from December to June. The research findings suggest that both increasing tank volumes and catchment surface can improve the reliability of the rainwater harvesting system.

Summary: This study used choice experiments to assess farmers' preferences and willingness to pay for attributes of on-farm water storage systems. Results showed high preferences and willingness to pay for all year water availability, reduced water resource conflicts, and improved water quality.

Summary: The importance of water and its effective use are increasing due to population growth and uncontrolled industrialization. Drought, caused by climate change, poses a threat to water resources. Factors such as water resource depletion, rapid population growth, unplanned industrialization, and drought lead to the need for alternative water resources. Rainwater harvesting, which collects and stores rainwater, can be used for agricultural and domestic purposes. In greenhouse areas, water can be collected through gutter systems on the roofs. In Antalya, Turkey, which has a significant number of greenhouses, the amount of rainwater that can be harvested annually is 224,992,795.8 m(3). Monthly calculations indicate that the lowest amount of water can be collected in August (938,447.53 m(3)) and the highest in December (54,771,210 m(3)). Therefore, building sufficient water storage facilities near greenhouses can support plant water needs.

Summary: This study investigated the estimation of the flexural capacity of beams using non-linear capabilities of two Artificial Intelligence (AI) models and conducted parametric and sensitivity analysis. The results showed that the Artificial Neural Network (ANN) model outperformed the Random Forest (RF) regression model in terms of accuracy and flexural strength performance. Increasing bottom reinforcement, width and depth of the beam, and compressive strength all improved the bending moment capacity. The change in bottom flexural reinforcement was found to be the most influential parameter.

Summary: This study found that incorporating wheat straw ash as an internal curing agent in concrete can effectively reduce autogenous shrinkage. The ultrafine SF-WSA slightly improves the mechanical properties of concrete, while the fine F-WSA has comparable strength. In terms of autogenous shrinkage, adding WSA can significantly reduce the shrinkage rate of concrete.

Summary: This study investigated the non-linear capability of artificial intelligence (AI)-based gene expression programming (GEP) modelling to develop a mathematical relationship for estimating the interfacial bond strength (IBS) of FRP laminates on a concrete prism with grooves. The developed model reflected close agreement between experimental and predicted results, indicating that the developed mathematical equation was reliable in estimating IBS based on the available properties of FRPs. The sensitivity and parametric analysis showed that the axial stiffness and width of FRP are the most influential parameters in contributing to IBS.

Summary: This study investigated the efficiency of a new composite material, consisting of layered double hydroxide (LDH) of ZnMgAl and rice husk biochar (RHB), for removing Cu(II) and Pb(II) ions from synthetic wastewater. The scanning electron microscope images revealed fine crystalline LDH particles on the rough surface of RHB, confirming the successful formation of the LDH/RHB composite adsorbent. The optimized dosage of LDH/RHB adsorbent at 0.4 g L-1 resulted in maximum adsorption capacities of 117 mg g-1 for Cu2+ and 124 mg g-1 for Pb2+, with removal efficiencies of nearly 94% and 99% respectively.

The maximum adsorption capacity of 151 mg g(-1) was observed when using the composite adsorbent of LDH and functionalized bentonite. The best-fit models for the adsorption process suggested monolayer adsorption, physical adsorption, and chemisorption as controlling mechanisms.
