摘要

在寒冷地区,河流结冰堵塞会导致许多河流发生严重洪灾。虽然冰塞通常在春季破裂时形成,但隆冬破裂会导致冰塞和洪水。尽管许多研究已经集中在预测春季冰塞洪水上,但与预测冬季中期冰塞和洪水严重程度有关的研究却很少。本研究的主要目的是开发一个随机框架来预测北美跨界(新不伦瑞克/缅因州)圣约翰河冬季中期冰塞洪水的严重程度。将水文(MESH)和水力模型(RIVICE)模拟相结合来开发随机框架。2018年发生的一次冬季中期河流决裂已被推迟作为一项案例研究。结果表明,该建模框架能够实时捕捉冰塞的严重程度。研究结果将有助于提高寒冷地区冰塞洪水管理能力。

Development of an ice-jam flood forecasting modelling framework for freeze-up/winter breakup
River ice-jams can create severe flooding along many rivers in cold regions. While ice-jams often form during the spring breakup, the mid-winter breakup can cause ice-jamming and flooding. Although many studies have already been focused on forecasting spring ice-jam flooding, studies related to forecasting mid-winter breakup jamming and flooding severity are sparse. The main purpose of this research is to develop a stochastic framework to forecast the severity of mid-winter ice-jam flooding along the transborder (New Brunswick/Maine) Saint John River of North America. A combination of hydrological (MESH) and hydraulic model (RIVICE) simulations was applied to develop the stochastic framework. A mid-winter breakup along the river that occurred in 2018 has been hindcasted as a case study. The result shows that the modelling framework can capture the real-time ice-jam severity. The results of this research will help to improve the capacity of ice-jam flood management in cold regions.

期刊介绍: Hydrology Research provides international coverage on all aspects of hydrology in its widest sense, and welcomes the submission of papers from across the subject. While emphasis is placed on studies of the hydrological cycle, the Journal also covers the physics and chemistry of water. Hydrology Research is intended to be a link between basic hydrological research and the practical application of scientific results within the broad field of water management.
