Summary: Stochastic rainfall models are important for evaluating hydrological risks, but there are discrepancies between rainfall metrics and flow metrics. The performance of different models varies depending on the strictness of the flow-based comparison and the region analyzed.

Summary: This study quantitatively investigated the impacts of PV panels on rainfall-runoff and soil erosion processes on a plot-scale slope through rainfall simulation experiments. The results showed that although the soil surface under the PV panel was rougher, there were no significant differences in runoff volume, peak flow discharge rate, and overland flow velocity between the panel slope and the control slope. However, the slope with the PV panel had significantly less sediment flux at the outlet, especially under heavy rainfall, due to the weakened splash erosion caused by the rainfall interception by the panel.

Summary: In dryland watersheds, infiltration excess overland flow is the dominant mechanism for runoff generation. Rainfall-runoff models partition precipitation into loss and excess precipitation components, with many using simple loss models due to the complexity and uncertainty of more sophisticated models at larger spatial scales.

Summary: Rain-induced surface runoff and seasons have short-to-medium-term anomalies on storm and wastewater flows and temperatures in wastewater resource recovery facilities (WRRF), while decentralized heat recovery (HR) technologies in buildings affect energy-related processes in urban water cycle and WRRFs. However, there is a lack of quantitative insights on thermal-hydraulic dynamics in sewers at network scale and different scales. Therefore, a modular framework is proposed to enhance the understanding of thermal-hydraulic dynamics and the water-energy nexus across the urban water cycle. The framework is validated using field measurements at full network scale, and simulation results suggest its ability to consistently predict temperature dynamics and quantify the impact of decentralized HR devices.

Summary: This study explores the extent to which spatiotemporal variability of intense rainfall affects runoff and flooding. Synthetic rainfall signals with different hyetograph variabilities are generated and applied to a hydrodynamic model for simulations in the Kan catchment in Tehran, Iran. The results indicate that temporal and spatial variability have different degrees of impact on runoff response and floodplain extents, with temporal variability showing a significantly higher effect than spatial variability. Furthermore, the influence of storm spatiotemporal variability on stream discharge and flood response is found to depend on the location within the drainage network.

Summary: In this study, a hydrological model is driven by observation-based hourly data and high-resolution climate model data to simulate river flows. The results show that the use of observation-based hourly data improves the accuracy of high flows and peak flow bias, but has little effect on low flows. The future changes in peak flows are slightly larger when driven by hourly climate model precipitation compared to equally-disaggregated daily data.

Summary: This study investigates the potential phosphorus runoff from sandy soils under conservation tillage, fertilized with recovered phosphorus from liquid swine manure and turkey litter ash in comparison with commercial phosphorus fertilizer triple superphosphate (TSP). Results show that the quantities of soluble reactive phosphorus (SRP) runoff from plots treated with recovered phosphorus from swine manure and turkey litter ash represent only 1% and 7-8% respectively of SRP runoff from plots treated with TSP, indicating lower environmental risks associated with the use of recovered phosphorus materials as crop fertilizers.

Summary: Rainfall simulation is a versatile and widely-used research tool, but may not fully capture natural processes. Validation studies suggest significant discrepancies between simulated and natural rainfall results, although adjustments can help approximate them.

Summary: Rainfall-runoff modeling is an important tool for flood forecast and water management. This study compared the performance of LSTM models with different look-back windows and found that rainfall data with spatial information improves the performance of the models. Additionally, using spatially distributed rainfall data can reduce the difference between regional and individual LSTM models.

Summary: Excessive phosphorus in aquatic systems poses a threat to ecosystem stability and human health. In this study, the impact of rainfall on total phosphorus concentration was quantified and a piecewise linear relationship was observed. Rainfall events were identified as a significant source of excess phosphorus load, mainly originating from non-artificial land.

Summary: Rainfall's spatiotemporal variability plays a key role in catchment runoff and flood response. This study assesses the sensitivity of runoff and flooded areas to rainfall movement in the Kan catchment (Iran). The results show that rainfall movement affects the runoff response, with higher velocities resulting in higher peaks and faster onsets of runoff. The direction of movement also plays a role, with storms moving along the average direction of the stream resulting in higher peaks and flooded areas. The influence of rainfall movement is also modulated by hyetograph structure and location within the drainage network.

Summary: There are various hydrological models available, with many using physically based formulations that require a substantial amount of spatial data. A new top-down approach for distributed rainfall-runoff modelling has been developed to combine accuracy and simplicity by deriving a distributed model with uniform parameters from a calibrated lumped conceptual model. The approach has shown improved performance in capturing internal catchment dynamics compared to the base model, although further improvements are needed for reliable results.

Summary: This study focuses on the application of CHIRPS-based Pitman modelling in the Berg Water Management Area (WMA) of South Africa. The simulation results using CHIRPS rainfall data show 80% suitability in simulating flows and a good similarity between observed and CHIRPS-based flows. Therefore, this research recommends the use of CHIRPS-based rainfall data as a suitable alternative in simulating flows for South Africa.

Summary: Delaying the time between slurry application and the first rainstorm event can decrease phosphorus losses in runoff, but the risk period for elevated concentrations may extend. The experimental results suggest that slurry P mineralization increases P concentrations and prolongs the P presence in runoff.

Summary: This review examines the applicability of rainfall simulation to draw inferences related to legacy P. A mixing layer model with chemical transfer is proposed to describe DP mobilization from pasture soils. Rainfall simulation protocols have severe limitations for developing relationships between DP in runoff and STP for estimating legacy P contributions to downstream water resources.
