SLODS: slow dissolving standards for water flow measurements

Abstract

In this study, we report the development of slow dissolving standard (SLODS™), designed to estimate water flow over a lunar period (30 days). To demonstrate the usefulness and validity of this technique, we describe successful preliminary calibrations, large-scale field experiments and the outcome of a detailed comparison with data obtained from clod cards during studies of giant-clam farming in villages in the Solomon Islands
