Evaluating the Utility of Selected Machine Learning Models for Predicting Stormwater Levels in Small Streams

Sustainability, Journal Year: 2024, Volume and Issue: 16(2), P. 783 - 783

Published: Jan. 16, 2024

The consequences of climate change include extreme weather events, such as heavy rainfall. As a result, many places around the world are experiencing an increase in flood risk. aim this research was to assess usefulness selected machine learning models, including artificial neural networks (ANNs) and eXtreme Gradient Boosting (XGBoost) v2.0.3., for predicting peak stormwater levels small stream. innovation results from combination specificity watersheds with techniques use SHapley Additive exPlanations (SHAP) analysis, which enabled identification key factors, rainfall depth meteorological data, significantly affect accuracy forecasts. analysis showed superiority ANN models (R2 = 0.803–0.980, RMSE 1.547–4.596) over XGBoost v2.0.3. 0.796–0.951, 2.304–4.872) terms forecasting effectiveness analyzed In addition, conducting SHAP allowed most crucial factors influencing forecast accuracy. parameters affecting predictions included depth, level, data air temperature dew point last day. Although study focused on specific stream, methodology can be adapted other watersheds. could contribute improving real-time warning systems, enabling local authorities emergency management agencies plan responses threats more accurately timelier manner. Additionally, these help protect infrastructure roads bridges by better potential implementation appropriate preventive measures. Finally, used inform communities about risk recommended precautions, thereby increasing awareness preparedness flash floods.

Family Dwelling House Localization in Poland as a Factor Influencing the Economic Effect of Rainwater Harvesting System with Underground Tank

Sustainability, Journal Year: 2023, Volume and Issue: 15(13), P. 10687 - 10687

Published: July 6, 2023

Considering water resources, Poland ranks among the last in Europe. By using rainwater for sanitary purposes, drinking is saved. This article presents results of economic analysis utilization systems, based on a novel view that takes into account factors related to location family detached house country, such as average annual rainfall and electricity prices. Two cases management systems (domestic-garden garden) were analyzed six locations, while considering diversity precipitation two variants, depending material tank, with options traditional electrical installation or photovoltaic panels. The evaluation profitability investment was carried out basis indicators: NPV, LCC, SPBT. analyses all variants give conclusion that, achieve greatest financial benefits, it crucial building’s demand fully met by rainfall, unit price significantly higher than electricity, operating costs are low possible through use renewable energy sources, subsidies significant percentage investment.

Smart and Innovative Systems for Urban Flooding Risk Management

Published: Sept. 13, 2023

Urban flooding is a serious issue that affects cities all over the world. Thus, there rising need for smart and innovative technologies to increase control of danger urban floods. This paper examines different technological advances strategies can potentially enhance flood management practices in areas, such as real-time monitoring systems, predictive modeling, early warning systems. stormwater drainage minimizes flash Advanced automated systems effectively flow after severe rainfall. Improving possible by integrating models, data visualization, risk assessment tools, hydraulic modeling software, hybrid decision support Accurate warnings evacuation, infrastructure protection, improved preparedness emergencies be generated with algorithms. The incorporation these intelligent enables areas take steps mitigate flooding, minimize damage, develop are both sustainable secure.
