“…In this analysis and the HEC-HMS model, the Koka reservoir in the Awash basin, and Gibe-3 reservoir in the Omo-Gibe basin were considered to indicate how they change their hydrologic response concerning flood controls and reserving water resources. An Excel spreadsheet was employed for the reservoir water balance analysis, using inflows to and from reservoirs using the water balance equation [44]. Water balance analysis uses the principle of conservation of mass in a closed system [45,46].…”

Hydrologic extreme events such as flooding impact people and the environment and delay sustainable development in flood-prone areas when it is excessive. The present study developed a seasonal floodwater forecast system for the Awash and Omo-Gibe basins of Ethiopia using the 2021 rainy season (June to September) as a temporal case study. In Ethiopia, there is no seasonal forecasting system available to cope with the recurrent flooding impacts instead of exercising ineffective and traditional monitoring approaches. The satellite-driven precipitation and temperature forecasts, observed rainfall, discharge, reservoir water levels, land cover, and soil data were used in the hydrologic (HEC-HMS) and hydraulic (HEC-RAS) models, spreadsheet, and GIS applications. The results obtained were forecasts of the runoff, reservoir water levels, and storage. The coefficient of determination (R2), Nash–Sutcliffe efficiency (NSE), percent of bias (Pbias), and Kling–Gupta efficiency (KGE) were used to evaluate the model’s performance in addition to plots as presented in the manuscript. The R2 values obtained for the Koka and Gibe-3 reservoirs’ inflows (water levels) were 0.97 (0.95) and 0.93 (0.99), respectively, and the NSE values were 0.90 (0.88) and 0.92 (0.95) for each reservoir. Similarly, the water levels (meter) and storage (Mm3) for the Koka and Gibe-3 reservoirs at the end of the 2021 flood season were 111.0 (1467.58) and 890.8 (13,638.5), respectively. Excess floodwater can be maintained in and released from reservoirs depending on the future water uses and flood monitoring activities downstream. In addition, the flood inundation extents from Earth remote sensing satellite observation and model results were examined and showed agreement.

“…According to Soejono Soekanto [19] there are several factors that influence law enforcement such as its own legal, namely legislation; law enforcement, the parties forming and applying law, facilities to support the enforcement of law, community, namely the environment in which the law applies or applies, cultural factors, namely as a result of work, creativity, and a sense that is based on human intention in life.…”

This paper aims to identify law enforcement in the city of Palembang, analyze the performance of officials in granting permits to transfer the function of wetlands to land built, and examine law enforcement in an effort to reduce flood risk. The the explanatory survey was used in this study. The sampling technique was done in random sampling. Data was processed descriptively, and also qualitative and quantitative analysis. This study carried out through observation, in-depth interviews, documentation and audio visual. The result shows that there are still exists a legal vacuum, the lack of commitment of authorities in enforcing the law relating to the reduction of the risk of flooding, lack of facilities and infrastructure landfills and drainage, the lack of culture dispose of waste in place and the lack of public awareness of the risk of flooding.

Constructed wetlands (CWs) are nature-based solutions that utilize natural vegetation, soils, and microbes to treat domestic wastewater and industrial effluents. They are engineered treatment systems that mimic the functions of natural wetlands to capture stormwater, reduce nutrient loads, and create diverse wildlife habitats. Providing these monetary and non-monetary benefits, its implementation has grown in several applications and geographical spread. Recent studies integrate the ecosystem services of CWs in project valuation, and the critical analysis of research hotspots has not been made yet. This study employs a systematic review to analyze the literature on ecosystem services provided by CWs and how they are incorporated into the valuation of CW projects. Among the ecosystem services that have been identified are provisioning (biomass and water supply), regulating (wastewater treatment and purification, climate regulation, flood prevention, and erosion control), cultural (recreation and aesthetic, biodiversity, education, and research), and supporting (habitat formation, nutrient cycling, and hydrological cycle). In terms of valuation methods and techniques, the results identified contingent valuation, shadow pricing, cost–benefit analysis, benefits transfer, habitat evaluation procedures, replacement cost, and travel cost. The analysis results provide researchers with a concrete basis for future studies and directions for further development. This also provides policymakers and CW project planners with valuable insights on various aspects of policy support for CW adoption and project valuation.
