Sand River

Dry and sandy riverbeds are seasonal watercourses that transport runoff-water from catchment areas to rivers or swamps once or several times a year. Dry riverbeds are also called ephemeral streambeds, seasonal watercourses or sand rivers. Most of the rainwater that is being transported downstream in riverbeds occurs as floods of several meters height. Sand rivers are only suitable as sand dams if coarse sand is available and the river is bedded on impervious bedrock (or clay like black cotton soil).
