Indus irrigation debates still touch brackish mixing zones. Where river outflow meets seawater, what basic coastal feature name fits a protected inlet often flanked by barrier islands?
Q1. Indus irrigation debates still touch brackish mixing zones. Where river outflow meets seawater, what basic coastal feature name fits a protected inlet often flanked by barrier islands?
Answer: A lagoon behind barrier islands or spits
Explanation: Where a river mouth is partially enclosed by barrier islands or spits, a sheltered coastal lagoon forms; these are common at delta fronts where longshore drift builds barriers across the river outflow.
