流域內(nèi)地形以低山丘陵為主，森林植被較差。農(nóng)業(yè)以糧食種植為主，礦產(chǎn)資源有砂金、鎢、錫。流域內(nèi)河系發(fā)達(dá)，上游河谷深窄，河道彎曲；下游河道寬淺，河床多沙。屬山區(qū)性河流。

赤土河流域面積204 平方公里，主河道長(zhǎng)度38.3千米,主河道縱比降3.42 ‰，流域平均高程259米,流域平均坡度1.40米/平方公里，流域長(zhǎng)度26.2千米,流域形狀系數(shù)0.30.流域多年平均降水量1530.0毫米,多年平均產(chǎn)水量1.65億立方米，水力資源理論蘊(yùn)藏量1.89萬(wàn)千瓦.建有橫寨、石子坳2坐小（1）型水庫(kù)及3座小（2）型水庫(kù)。
