摘要

En 中文
本研究评估了四种水文方法，特别是合理法（Rational method）、Fuller公式、EBA4SUB和STORAGE + COSMO4SUB（S + C）模型，在Gidra河（斯洛伐克）五个子流域中针对2–1000年重现期（T）的应用。在观测的Píla子流域中，所有方法均偏离了官方设计流量（6–44.5 m³/s），其中经验方法表现出系统性高估（例如，2年重现期时高达35 m³/s，而官方值为6 m³/s），而Fuller公式在长重现期时高估幅度可达三倍。S + C模型提供了更接近的吻合度，通常在两倍误差范围内。在无观测流域中，峰值流量范围从近0至479 m³/s，方法间的变异性（T = 1000年时的变异系数CV）从小流域的0.65降至大流域的0.55。经验方法大多与流域面积呈线性关系，这可能过度简化了底层水文过程。而更具物理基础的S + C方法虽能提供内部一致性结果，但需要谨慎的校准与验证。
