5、壓力、緩解XX水資源緊缺的重要措施。北運(yùn)河是XX唯一一條常年有水而且水量極為豐沛的河道,每年有大量的雨洪未能有效利用。探討在確保城市防洪安全的前提下,充分利用雨水資源,創(chuàng)造優(yōu)美的水環(huán)境。關(guān)鍵詞：北運(yùn)河雨洪利用分析

1999年以來(lái),XX已連續(xù)7年干旱,XX兩大地表水源,密云水庫(kù)、官?gòu)d水庫(kù)蓄水急劇減少。地下水位持續(xù)下降,平原區(qū)地下水埋深已超過(guò)20m。水資源急劇短缺。同時(shí),隨著XX城市化進(jìn)程的加快,不透水面積大幅度增加,致使相同降雨條件下,徑流系數(shù)增大,洪峰提前,洪量增大,對(duì)城市排水和河道行洪構(gòu)成巨大
